Inflammatory diarrhœa, or dysentery, not only follows the continuance of the simpler forms of the disease, but sometimes in the hot months of summer or autumn sets in suddenly with violence. It then frequently commences with vomiting, and the stomach may continue so irritable for twenty-four hours as not to retain even a teaspoonful of cold water. At the same time the over-action of the bowels sets in, and twenty or thirty evacuations may be passed in twenty-four hours. The motions soon lose their natural character, and become watery, slimy, and mixed with blood. They are at first expelled with violence, afterwards with much pain, effort, and often fruitless straining. With these local symptoms, the child, as might be expected, is very ill, feverish, and stupid, though without sound sleep, much exhausted, and its nervous system so disturbed as to occasion frequent twitchings of the fingers and of the corners of the mouth, while sometimes actual convulsions take place. The thirst is intense, the child calling constantly for cold water, and crying out for more the moment the cup is taken away from its lips; while the loss of flesh and the exhaustion are more rapid than in any other disease with which I am acquainted. The fat happy babe of four and twenty hours before is scarcely to be recognised in the miserable little being, with sunken lustreless eyes, and wizened features, and miserable countenance, lying in a state of half-stupor, sensible only to pain, which yet rouses it but to utter a moan, and then sinks again into silent suffering. I can well believe what we are told, that in some countries this, the so-called Summer Complaint of many of the American cities, sometimes carries off children in a few hours.

If a fatal termination does not take place speedily, the disease passes into the chronic stage, the diarrhœa diminishing in frequency, but the pain and straining, and the unhealthy character of the evacuations persisting. Ulceration of the bowels has taken place, emaciation becomes extreme, and the child often sinks at the end of several weeks, worn out by suffering; while recovery, doubtful at the best, is always very slow. But I need not pursue this subject further: enough has already been said to show how little infantile diarrhœa is a disorder for domestic management.

Peritonitis, or inflammation of the membrane covering the bowels and lining the cavity of the belly, is of excessive rarity in its acute form; and is attended by such general illness and such severe local suffering, that it is impossible to overlook it or to misapprehend its gravity. Severe pain in the belly is sometimes complained of by children, and is due to what is termed colic, a spasm of the bowels which is generally associated with constipation. The great test of the cause of the pain is furnished by the presence or absence of tenderness on pressure. The pain of colic is relieved by gentle pressure and gentle rubbing. The pain of inflammation in any degree and of any kind is aggravated by them. This applies also to cases, not indeed very common, in which inflammation is set up by some small body, such as a cherry-stone getting fixed in a little offshoot or appendage of about the size and length of the little finger, connected with the commencement of the large bowel, and producing ulceration. In these circumstances the bowels are confined, there are nausea and sickness, together with pain and tenderness of the belly, especially on the right side. The disease is a very dangerous one, and often proves fatal in the course of a few days. I refer to it because I have often seen it overlooked both by parents and doctors at its outset, since the pain then is often not severe nor the tenderness intense, and because I have seen the patient's condition rendered hopeless by strong aperients being given to overcome the constipation which was supposed to be all that ailed the child. I repeat then the caution, never to overlook the existence of tenderness, never to attempt to treat a case in which it is present; but always to call in medical advice, and above all always to abstain, unless ordered by a medical man, in every such case from the use of aperients.

Large Abdomen.—I must not leave the subject of disorder of the digestive organs without some reference to a condition which often excites much needless anxiety among mothers, namely, the large size of a child's belly. This is sometimes supposed to be a certain evidence of the presence of worms, at other times to be a positive proof of the existence of grave disease, especially of disease of the mesenteric glands, or glands of the bowels as they are popularly termed. It is evidence of neither the one nor the other.

If you go into a gallery of the old masters, and look at any of the pictures of angels which are generally to be seen there in such abundance, you will probably be struck in the case of all the child angels by what will seem to you the undue size of their abdomen. You will notice this even in the works of painters who, like Raphael, most idealise their subjects, while in those of others who, like Rubens, interpret nature more literally, the apparent disproportion becomes grotesque; or, in the coarser hands of Jordaens, even repulsive.

These painters were, after all, true interpreters of nature. In infancy and early childhood the abdomen is much larger comparatively than in the grown person. For this there is a twofold cause; the larger size of the liver on the one hand, and the smaller development of the hips on the other. In a weakly child this appearance is exaggerated by its want of muscular power, which allows the intestines to become much distended with air. If the child is not merely weakly but also ricketty, the contracted chest will leave less room than natural for the lungs, while at the same time the ordinary development of the hips being arrested by the rickets, the disproportion is further increased both by that and by the flatulence due to the imperfect digestion with which the condition is almost always associated.

In no case need the mere size of the abdomen occasion grave anxiety, so long as when the child lies upon its back the abdomen is uniformly soft, nor so long as even if tense it is not tender, and as it everywhere gives out a hollow sound like a drum when tapped with the finger.

It is not for a moment meant that no notice is to be taken, nor opinion asked, as to the cause of excessive size of the abdomen, for its distension may be due to real disease; but it is yet worth while to remember that its mere size is not of itself evidence of disease, nor cause of grave anxiety.

Worms.—There is no mistaking or overlooking the existence of worms when they are really present. Their presence, however, is often suspected without any sufficient reason. Ravenous or uncertain appetite, indigestion, flatulence, undue size of the abdomen, a dark circle round the eyes, itching of the nose and of the entrance of the bowel, a coated tongue, and offensive breath are no real proof of the presence of worms, and do not justify the frequent repetition of violent purgatives or of so-called worm medicines. The only real proof of the presence of worms is their being seen in the evacuations.

The worms commonly found in children are either the round-worm, which resembles the earth-worm, the thread-worm, or the tape-worm; the appearance of each of which is clearly indicated by its name. None of them are spontaneously generated in the body, but they are all introduced from without; their eggs, or, as they are technically called, their ova, being swallowed unperceived in some article of food, or drink. A proof of this is afforded by the fact that an infant, so long as it is nourished exclusively at the breast, never has worms.

The round-worm occasions the fewest symptoms, and is rather an object of disgust than of grave importance, at least in this country, where it seldom happens that more than two or three are present. In other countries, as some parts of Italy, for instance, where the drinking water is bad and stagnant, they are sometimes found in great numbers, as thirty or forty, and it is then not easy to determine whether the symptoms which accompany them are produced by the worms, or by the unwholesome character of the water in other respects.

They appear to live on the contents of the intestines, and do not adhere to them, as the tape-worm does, and hence their comparative harmlessness, and they have no power, as has sometimes been mistakenly imagined, of perforating the bowels, and of thus producing grave mischief.

The thread-worm is the commonest variety of these creatures, and has the peculiarity of inhabiting the lowest twelve inches of the bowel, where it produces much irritation and causes very distressing itching. It is often present in great numbers, and is so rapidly reproduced, that in a week or two after it has been apparently got rid of, it may again be found as numerous as before. Certain articles of food seem to favour its development, such as pastry, sugar, sweets, beer, fruit, and anything which is apt to undergo fermentation, and thereby to impart to the evacuations a specially acid character. These worms are often accompanied with more or less marked symptoms of indigestion, but otherwise the local irritation is usually the only indication of their presence. They produce, indeed, such disturbance of the nervous system as may attend indigestion in any of its forms, but I have never but once known convulsions occur apparently due to their presence in great numbers, and ceasing on their expulsion; and this was in a child between eighteen months and two years old.

The tape-worm is developed in the human body from a minute germ or ovum; one form of which exists in the flesh of the bullock, the other in that of the pig; and which seems to require for its growth the favouring conditions of warmth and moisture which are found in the intestines. It fixes itself to the lining of the bowels by means of its mouth, which is furnished with minute tentacles, and it thus derives its support from the juices which it imbibes. The head is so small as not to be seen distinctly without a magnifying glass; and immediately beyond it the jointed body begins; at first, scarcely bigger than a thread of worsted, but gradually enlarging, till at the distance of three inches it is an eighth of an inch wide, and thence rapidly widens till each joint is half an inch wide, and from a third to half an inch apart. It does not exceed these dimensions, even though it may grow to the length of four or six yards. Portions of it, sometimes a yard or two in length, are thrown off from its lower end occasionally, and this occurrence often gives the first indication of its presence, the worm continuing to grow as before, and fresh portions being detached from time to time. It does not appear that the worm has the power of reproducing itself; hence its French name of ver solitaire, and the occasional presence of two or three would seem to be due to the development of two or three distinct ova within the intestine.

Deriving as it does its support from the system of the child, and not as the other worms do from the contents of the bowel, the tape-worm often produces graver inconveniences. It sometimes causes uncomfortable colicky sensations, which may even be very distressing, and the disorders of digestion which accompany it are often very considerable; certainly more so than in the case of the other varieties of worms; but I have seen no instance of convulsions which could be attributed to them, notwithstanding the generally received opinion to the contrary.

When the existence of worms is suspected, one or two doses of a simple aperient, such as castor oil, repeated two days successively, seldom fail to produce evidence of their presence; which in the case of tape-worm is also furnished by the spontaneous detachment of some of the joints. It must be remembered, however, that until the head has been detached from its connection with the bowel, nothing has been gained, and the tape-worm will in a short time grow again. To obtain the detachment of the head it is necessary that any worm medicine should be given when the intestines are empty. I am, therefore, always accustomed to give a dose of castor oil about two hours after the child's mid-day meal; and to send the child to bed as soon as the aperient begins to act, and to give it no more food except a biscuit and a little milk and water during the rest of the day. In the early morning, the special worm medicine is given, and over and over again I have known the worm to be brought away completely after many previous failures. When the smallness of the joints shows that the greater part of the worm has been thrown off, and that little more than the head remains, it is necessary to have recourse to the unpleasant proceeding of mixing the evacuations with water, and then straining them through muslin, in order that the doctor may by means of the microscope make out whether or no the head has been really detached. This is no question of mere curiosity, but a matter of the gravest moment, since nothing has been really gained so long as the head of the worm remains adherent to the bowel.

Precautions such as these are not needed in the case of the other kinds of worms. Thread-worms, however, are best attacked in their habitation; that is to say, in the lower bowel, by means of lavements. It is, therefore, desirable before they are administered that the bowels should be emptied by a dose of castor oil.

The only other caution which remains for me to give refers to the peculiar effect which salicine, a very valuable medicine, especially in the case of thread-worms, has upon the urine. It sometimes turns the urine of a greenish-yellow, often of a red colour, as though it were mixed with blood. The appearance, however, has no grave meaning, but is due simply to a chemical action of the medicine on the colouring matter and salts of the urine.

There still remain some local ailments of parts connected with the process of digestion, concerning which a few words must be said.

Ulcerated Mouth.—First, with reference to the sore-mouth of children. I have already noticed a form of inflammation and ulceration of the gums sometimes met with during teething, but the sore-mouth of which I am now about to speak is often quite independent of that process; though it may sometimes be found associated with it, and is indeed rarely met with after five years of age. In almost all instances it is preceded and attended with symptoms of indigestion, during the course of which the mouth becomes inflamed, hot and red, and small very painful shallow ulcers with sharp-cut edges, and a little yellowish deposit on their surface, appear at the edge of the tongue, on the inside of the mouth, and especially on the inside of the lower lip, and the adjacent surface of the gum. Successive crops of these little ulcerations not unfrequently appear, so that for many weeks the child may be kept by them in a state of extreme discomfort; swallowing, and even speaking being the occasions of considerable suffering.

It is seldom that nursery remedies, and the so-called cooling medicines, though often of some service, suffice to get rid of the ailment, which for the most part needs judicious medical treatment, and local as well as constitutional measures. Now and then this condition comes on in the course of measles, and is then sometimes of serious importance.

In the other form, the disease is usually limited to the gums, and affects especially those of the front of the lower jaw, which become swollen, ulcerated at their edges, where a very ill-smelling deposit takes place of a dirty white or greyish colour, the surface beneath being spongy, swollen, raw, and bleeding. The ulceration sometimes extends so as to lay bare a large part of the sockets of the teeth; but though loosened they seldom drop out. Coupled with this, the glands at the angle of the jaw are swollen, and the child dribbles constantly a large quantity of horribly offensive saliva. In the children of the well-to-do classes the condition is seldom seen except in a slight degree; but even when severe it is rarely accompanied by any grave disorder of the general health. It seems to tend, whether treated or left to itself, slowly to get well; but its progress to a natural cure is extremely tedious, and the gums are left by it for a long time spongy, bleeding easily, and only very imperfectly covering the teeth.

Anxiety is sometimes excited by this condition; it being supposed that the white deposit on the edge of the gum implies some relation between it and diphtheria. This is not so, for though this peculiar ulceration of the gums has now and then been found associated with diphtheria, the nature of the two diseases is essentially different. It is, however, always wise to call in medical advice in order to settle this important question, and the more so, since there is one remedy, the chlorate of potass, which, in appropriate doses, acts upon the condition almost as a charm.

I say nothing about a dreadful form of inflammation of the mouth which ends in mortification, because it is of infinite rarity except among the destitute poor, and even among them it is very seldom seen except as a consequence of measles, or of some kind of fever. It is only among the very poor that I have seen it, and even among them it has come under my notice only ten times in the whole course of my life.

There is a very common but inaccurate opinion that sore-mouth in childhood is often produced by the employment of mercury. I never yet saw a sore mouth due to the administration of mercury in any child before the first set of teeth were entirely cut; and never but once out of 70,000 cases which have come under my notice in hospital or dispensary practice, have I seen in children of any age under twelve any affection of the mouth from mercury sufficiently severe to cause me a moment's anxiety.

Quinsey, or inflammatory sore-throat, has in it nothing specially peculiar to the child, but occurs at all ages with the same symptoms. It is, however, comparatively rare under twelve years of age, and is almost always less severe in childhood than at or after puberty, while I scarcely remember to have met with it under five years of age. This circumstance attaches special importance to sore-throat in young children, since it will usually be found to betoken the approach of scarlet fever, or of diphtheria, rather than the existence of simple inflammation, or quinsey.

While this fact affords a reason for most scrupulous attention to every case of sore-throat in children, and this in proportion to the tender age of the child, needless alarm is sometimes caused by the appearance on the inflamed tonsils of numerous white specks, which are at once supposed to be diphtheritic. I have already pointed out the distinction between the two conditions when speaking of diphtheria, but the matter is so important that I will repeat what I then said. These spots are not in the form of a uniform white patch or membrane, which, on being removed, leaves the surface beneath red, raw, and often slightly bleeding; but they are rather distinct circular spots, firmly adherent to the tonsil, wiped off with difficulty, and evidently exuding from the openings of little pits, blind pouches, or glands, with which the surface of the tonsil is beset. I do not advise any parent to rest satisfied with his or her judgment on this matter the first time that they notice this appearance; but there are children with whom slight sore-throat is always attended by this condition, and others in whom the tonsils are habitually enlarged, and seldom free from these white spots flecking their surface.

Enlarged Tonsils.—I have said that quinsey or acute inflammation of the tonsils is unusual in early childhood; but a sort of chronic inflammation of those glands which leads to their very considerable enlargement is far from uncommon; and is sometimes the cause of very serious discomfort. It is seldom traceable to any acute attack of sore-throat, but usually comes on imperceptibly in children who are feeble or out of health, or takes place slowly during the cutting of the first set of grinding teeth; the irritation which that produces being in some cases its only apparent exciting cause. Not seldom the enlargement has become considerable before it attracts attention; one of the first symptoms that indicate it being the loud snoring of the child during sleep, who is compelled by the obstruction at the back of the nostrils to breathe with its mouth open. The voice at the same time becomes thick, and this and the snoring breathing are both greatly aggravated when the child catches cold.

A greater degree of enlargement of the tonsils occasions deafness from pressure on the passage leading to the internal ear, and is also apt to give rise to a troublesome hacking cough which sometimes excites apprehension lest the child's lungs should be diseased. When still more considerable the enlarged tonsils block up the passage through the nostrils, and air consequently enters the lungs but very imperfectly. The nostrils thus disused become extremely small, narrow, and compressed, the upper jaw does not undergo its proper development, the teeth are crowded and overlap each other, the palate remains narrow and unusually high-arched, and the face assumes something of a bird-like character. Besides this the child grows pigeon-breasted, owing to the lungs not being filled sufficiently at each inspiration to overcome the pressure of the external air on the yielding sides of the chest.

When any considerable enlargement of the tonsils exists, each cold that the child may catch aggravates it, and if diphtheria, scarlatina, or severe sore-throat should occur, the temporary increase of the swelling may become the occasion of serious danger. The question arises, what are the chances that a child whose tonsils are enlarged will outgrow the condition, or when is it necessary to have the enlarged tonsils removed?

It scarcely ever happens that any such enlargement of the tonsils exists in children under six years of age as to call for their removal. There is almost always ground for the hope that after the irritation caused by cutting the first four permanent grinding teeth has completely ceased, the tonsils may return by degrees to their former size. A similar shrinking of the enlarged tonsil sometimes takes place, especially in the boy, at the time of approach to manhood, when the vocal organs undergo full development. This can be counted on, however, only in cases where the tonsils are not of extreme size, and have not undergone frequent attacks of inflammation. Whenever the hearing is habitually dull, and the voice always thick, when cough is frequent, the nostrils narrow, the chest pigeon-breasted, and the child feeble and ill-thriven, removal of the tonsils is absolutely necessary. In cases where the question is doubtful, its decision must turn on whether the tonsils have often been inflamed. So long as their surface is smooth, and their substance soft and elastic, delay is permissible. When their substance is hard, like gristle, and their surface uneven and corrugated, they have undergone such changes that absorption is impossible, and their removal absolutely necessary.

I dwell thus particularly on the question of removal of the tonsils, because there is among many persons an unreasoning dread of the operation, which is entirely devoid of danger, requiring only a few seconds for its performance, and which may even be done under chloroform. The painting tincture of iodine behind the angle of the jaw, or the touching the tonsils with caustic, iodine, alum, tannin, or sweet spirits of nitre are utterly futile proceedings. They diminish the unhealthy and often offensive secretion from the glands which beset the tonsils, and restore the surface to a more healthy condition, but they are absolutely without influence in lessening their size.

Now and then all the symptoms of enlarged tonsils are present, but yet most careful examination fails to discover any increase of their size. When this is the case the symptoms are due to a thickening of the membrane at the back part of the nostrils, often attended with spongy outgrowths from their surface, which obstruct just as completely as enlarged tonsils would do the free entrance of air. It will, in any case where this condition is suspected, be absolutely necessary to seek the advice of some of those gentlemen who make a specialty of diseases of the throat, and who will have the necessary technical dexterity to discover the condition, and to treat it skilfully.

Abscess at back of the Throat.—I should pass unnoticed, on account of its rarity, the occasional formation of an abscess at the back of the throat, behind the gullet, interfering both with breathing and with swallowing, but that the description of it in my Lectures once enabled a lady in the wilds of Russia to detect it, to point out the nature of the case to her puzzled doctor, to urge him to open the abscess, and thus to save her child's life.

This abscess may form at any age, sometimes after fever, sometimes without any obvious cause. It shows itself by difficulty in swallowing and breathing, unattended by cough, but accompanied by a sound similar to that of croup, but not so harsh or ringing. The neck is stiff, the head thrown back, and often there is a distinct swelling on one or other side of the neck. The finger introduced into the mouth, and carried over the tongue to the back of the throat, feels there a swelling which projects over the top of the windpipe, and causes the difficulty both in swallowing and breathing. This swelling is the abscess; a prick with the surgeon's lancet lets out the matter, and saves the child.

Diseases of the Kidneys.—The kidneys perform very important duties in carrying off from the system a large amount of useless material, and thus supplement in many respects the action of the skin, and the purifying influence which is exercised by the air on the blood, as it passes through the lungs.

It is evident, therefore, that their disorder in any way must be a matter of serious moment, though at the same time the knowledge of the skilled doctor is needed to determine the nature and degree of the ailment from which they are suffering, since that requires an examination of the urine, both chemically and by means of the microscope. My remarks on these diseases must consequently be few and fragmentary.

In the grown person, what is known as Bright's disease is of frequent occurrence, assumes different forms, and depends on various causes. In the child it is comparatively rare, and is scarcely ever met with except as a consequence of a chill, or as a result of scarlatina. In these conditions the kidneys become overfilled with blood or congested, and the congestion may pass into inflammation, by which their structure may be irreparably damaged. Dropsy is the great outward sign of the affection—either slight swelling of the face, eyelids, and ankles, or very great swelling of all the limbs, and even the abundant pouring out of fluid into the belly. The degree of dropsy is, however, by no means an absolute measure of the amount of kidney mischief. It therefore behoves every parent to follow out all directions most scrupulously even in cases of very slight dropsy, in order to guard against the risk of permanent injury to the kidneys being left behind; and especially to remember the liability to the occurrence of dropsy and disease of the kidneys after scarlatina. Any check to the action of the skin while it is peeling or desquamating, as it is termed, is especially liable to be followed by these accidents. To avoid all risks as far as possible, I have been accustomed for many years to insist on a child remaining in bed for one-and-twenty days after the first appearance of the rash in even the mildest case of scarlatina, and I am absolutely sure that it is the height of imprudence ever to neglect this precaution.

It will suffice to mention the fact that diabetes, though very rare, may yet occur in childhood, and that as a rule it is more dangerous in childhood than in the grown person. Whenever a child loses flesh without obvious cause, suffers much from thirst, and at the same time passes urine in greater abundance than in health, the possibility that it may suffer from diabetes must be borne in mind.

Of far greater frequency than any other affection of the kidney is that in which the child passes gravel with the urine, either in the form of a reddish-white sediment, which collects at the bottom of the vessel as the urine cools, or of minute glistening red particles, which resemble grains of cayenne pepper.

These deposits, when abundant in the male child, have a tendency to collect in the bladder, and there to form a stone. This painful disease, too, is so much more frequent in childhood than at a later age, that more than a third—indeed, nearly half—of all the operations for stone performed in English hospitals are done on boys under ten years old.

Even when this grave consequence does not follow the presence of gravel in the kidneys, and its passage into the bladder, it is often accompanied with much suffering. The pain is like that of stomach-ache or colic, the child crying and drawing up its legs on every attempt to pass water, which sometimes is voided only in a few drops at a time, and now and then is completely suppressed for some hours. The very acute form of the ailment seldom occurs, except in infants who inherit from their parents a disposition to gouty or rheumatic affections. In them, however, a trifling cold, slight disorder of the digestion, a state of constipation, or the feverishness and general irritation which sometimes attend on teething, not infrequently produce these deposits and give rise to all these painful symptoms, the deposit disappearing and the pain ceasing so soon as the brief constitutional disturbance subsides.

The very acute attacks seldom occur after the first two years of life, but similar symptoms, though less severe, are by no means unusual in older children, and continue to recur from very trifling causes, especially from errors in diet and disorders of digestion.

In spite of the suffering which for the time attends it, there is no cause for anxiety with reference to the issue of each attack. The warm bath, a castor oil aperient, and soothing medicine soon relieve the pain, and the children return to their former state of health. It is the frequent return of the attack, even in a comparatively mild form, the persistent disposition to the formation of gravel, the remote risk in the case of male children of stone in the bladder, and the habitually imperfect performance of the digestive functions which call for special care. The avoidance of sugar, sweets, and whatever tends to impart acidity to the urine, the maintaining the due action of the skin by wearing flannel, and the judicious use of alkaline remedies, sometimes combined with iron, are the measures on which the doctor is sure to insist.

The difficulty usually encountered in the treatment of these cases arises from the reluctance of the parents to continue for months and years the observance of the necessary rules. It seems so hard to deny their little one the small gratifications in which other children may indulge with impunity; and they fail to realise the heavy penalty, in the shape of gout, rheumatism, gravel, and stone, which in after-life their darling may have to pay for their over-indulgence in his early years.

I will just mention that symptoms similar to those above described, less severe, though more abiding, yet unattended by gravel in the urine, are sometimes produced in little boys by an unnatural narrowness of the end of the passage for the urine. It is well to bear in mind this possible cause of the child's sufferings, and to consult a doctor with reference to it, since he will be able to relieve it by a trivial operation.

Incontinence of Urine.—The irritation which this mechanical inconvenience produces sometimes has to do with that troublesome infirmity of some children, who wet the bed at night. This may also be induced by a very acid, and consequently irritating, state of urine, either with or without the appearance in it of gravel. Often, however, it is a result of want of care on the part of the nurse, who neglects to cultivate regular habits in a child; and does not pay attention to the quantity of liquid taken at its last meal. Something, too, is due to the fact that the sleep of a child is deeper than that of the grown person, so that the sensation of want, which would arouse the latter to full consciousness, does not have the same effect on the former. It sometimes happens undoubtedly from mere indolence; and this may always be suspected when a child, otherwise healthy, wets itself not at night only, but also in the daytime. Lastly, it does sometimes occur from muscular feebleness in weakly children, the bladder being unable to bear more than a limited degree of distension.

The accident usually happens either soon after going to bed, when the warmth stimulates the action of the bladder, or towards morning, when the bladder has become full. The posture on the back favours its occurrence very much, and it is therefore of importance that the child should lie on its side when in bed. The good effect of a blister on the lower part of the back as a means of cure was largely due to its forcing the child to lie on its side. This object can be attained, however, in a much kindlier way, by tying half a dozen cotton reels together, and fastening them at the child's back. The habit may also often be broken through by arousing the child in the night, and compelling it to empty its bladder, the hour being first ascertained at which the accident usually happens. For this, however, to be of any real use, the child must be awakened thoroughly; since otherwise it will mechanically, and quite unconsciously, empty its bladder while still asleep. The habit in this case is not in the least overcome; only for the time the bed escapes the wetting. The utensil must therefore be placed on different nights at different parts of the room, so that the child, in order to find it, must have been roused to thorough consciousness.

Lastly, I will add that the cases in which the accident is the result of mere indolence are very rare, and though in such cases strictness may be necessary, yet actual punishment is out of place. As a rule, reward answers much better. A penny, or a threepenny-piece every night that the accident does not happen, and a forfeit of a halfpenny or two pence for every night of misfortune, is a very efficacious help to a cure.

When all these domestic means, persevered in for months, fail to produce any result, medical aid must be called in.

CHAPTER IX.

Consumption and Scrofula, though similar, are not the same disease. Both, however, depend on some defect in the blood, as the result of which certain materials, incapable of being converted into the natural constituents of the body, are deposited in the substance of different external parts or internal organs. If deposited in small quantities, these materials may be absorbed, as it is termed, that is to say, got rid of, by natural processes, which even now we understand but imperfectly.

If deposited more abundantly, they press upon and gradually spoil the healthy parts in which they are seated, and thereby interfere with the proper performance of their duties. Thus, the deposit of consumption encroaches on the proper substance of the lungs, and so lessens the area in which the blood is exposed to the air and purified: the deposit of scrofula around and in a joint interferes with its powers of movement. Nor is this all; but wherever any deposit has once taken place, it tends especially to increase in that very spot, guided as it were by a certain affinity; and the substance of the previously healthy part is removed as fresh deposit comes to occupy its place. Further, the matter deposited has no power of being changed into healthy substance of lung, or of bone, or of any other part.

A fractured limb may be completely mended; a fluid is poured out around and between the edges of the broken bone; by degrees this hardens, it undergoes changes which convert it into solid bone, and the limb is once more as serviceable as before, though some indications of the fracture may still be perceptible in the texture of the bone itself. Or, a person receives a severe blow on his arm or leg; in course of time the blood which had flowed from the ruptured vessels, and had formed a big bruise, is absorbed, and all is as before the injury was inflicted. If more serious damage has been done, the fibres of some muscles may have been torn, even though the skin remains unbroken. Inflammation is set up, the injured parts die, and are melted down into the matter of an abscess. The abscess discharges itself, its walls contract, the opposite surfaces come into contact, and are welded together again, so that there is no loss of substance, nor anything save a scar on the surface to indicate what has happened.

In the case of the deposits of consumption or scrofula these changes cannot take place. In technical language the matter is said to be incapable of organisation; that is to say, it cannot be transformed by nature's alchemy into anything good or useful. It is rubbish to be got rid of; and the patient's recovery depends on the possibility of getting rid of it. If there is much of it, so as to be removed from the vivifying influence which adjacent living structures still maintain about it, the deposit softens at its centre. This softening gradually extends to the circumference; the mass irritates more and more the parts around it, and where the irritation is greatest the structures yield, and are removed to make a way for its escape, and the patient spits up the contents of the abscess.

But the abscess of the lungs is not like an abscess which follows an injury. It has not formed in the midst of previously healthy parts which are capable of reproducing the original structure; its walls are themselves involved in the disease, and, in accordance with the rule I have already mentioned, 'much will have more,' and the patient goes on spitting up the perpetually renewed contents of the abscess for months or years; until by its gradually increasing size, and the more and more abundant discharge of matter, and further and further destruction of lung-substance, death takes place.

This fatal issue, however, is not invariable. In favourable circumstances, and especially in childhood, the radical constitutional defect may be amended, and with a healthier condition of the blood the unhealthy deposit may cease to take place. The lung-substance, however, with all its curious structure of air-cells and their network of minute vessels where, as in nature's laboratory, the blood receives its due supply of oxygen, is not reproduced. The lung shrinks, the sides of the abscess come together, and by slow degrees a dense material cuts it off from the adjacent healthy structure, but the most complete recovery leaves the patient with his breathing power lessened, and with his vigour consequently more or less impaired.

When the deposit is less considerable, a different change takes place. The material dries by degrees, and is at last converted by a purely chemical change into a hard chalky substance, which in the course of time becomes of more than stony hardness.

Last of all; when the deposit is smallest in quantity, it may be completely got rid of; and a lung in which consumptive disease once existed, may eventually regain perfect soundness.

I have dwelt on these processes as they take place in the lungs; but, allowing for differences of locality, they resemble such as take place elsewhere.

Three important conclusions follow from what has been said.

First. It is only in quite the early stage of consumptive disease that absolutely perfect recovery can be hoped for. There is a euphemism, more amiable than honest, which doctors not seldom make use of, saying that a child's lungs are not diseased, but only tender. They mean by this, that on listening to the chest, they detect such changes in the sounds of breathing as their experience tells them are usually produced in the early stage of consumptive disease of the lungs. If the opinion is confirmed by a second competent medical man, then, and not later, is the time for precautions, for removing the child from school, and for selecting, as far as may be, a suitable winter climate. When the signs of disease are well marked, a reprieve, perhaps a long one, is all that can be confidently reckoned on.

Second. When softening of the consumptive deposit has taken place, of which certain sounds attending breathing are all but conclusive, recovery, even the most complete, always implies loss of a certain amount of lung-substance, and consequently loss of a certain amount of breathing power.

Third, and this is most important, as well as most cheering; consumption, which is at no age the absolutely hopeless disease that it was once supposed to be, admits of far more cheerful anticipations in children than in grown persons, or, for that matter, than in the youth or maiden.

The principal causes of consumptive disease are, hereditary predisposition, and improper feeding in infancy. There are besides two diseases incidental to childhood, and one of them almost peculiar to it, namely typhoid fever and measles, which are more apt than any others to develop a tendency to consumption. During convalescence from either of them, therefore, special care is needed.

In the grown person, consumption almost always attacks the lungs, and this often to the exclusion of other organs. In the child, however, this is not so, and though the lungs are indeed oftener affected than other parts, yet in nearly half of the cases some one or other of the digestive organs is likewise involved, and in about one in seven instances the lungs are free and the digestive organs alone are attacked.

Fever, cough, and wasting are the three sets of symptoms which in some degree or other are always present in consumptive disease of the lungs. The fever in the early stages of consumption is not in general severe; but so long as the evening temperature of a child never exceeds 99°, there is no cause for anxiety. On the other hand, if the evening temperature for a week or ten days together always amounts to 100°, there is grave presumption that consumptive disease is present. In advanced consumption the evening temperature is constantly 103° to 105°, while in the morning it may fall to 101° or 100°.

Cough is but rarely absent even in cases where the lungs are but slightly involved, for the irritation of the digestive organs often excites a sympathetic cough, and in these circumstances observation of the evening temperature will often furnish a clue to the right interpretation of the symptoms.

There is a form of cough which is oftenest observed in children between the ages of two and five years, which comes in fits closely resembling those of hooping-cough, and each fit ends in a sort of imperfect 'hoop.' This may depend on a particular form of consumption in which the glands connected with the lungs (the bronchial glands as they are called) are diseased, and not the lung-substance itself. The enlarged glands press on some of the nerves connected with the upper part of the windpipe, and thus occasion the spasmodic cough. Always suspect this when a cough persists for weeks together, not getting rapidly worse as hooping-cough would do, but at the same time not growing better, as would be the case with mild hooping-cough. The doctor on listening to the chest will solve your doubts; the thermometer will help you to decide whether his visit is necessary. I may add that this form of consumptive disease is less serious than that in which the lung-substance is involved.

Consumption sometimes follows bronchitis, especially when a child has been subject to frequent attacks of it. A very slow and imperfect recovery from an attack of bronchitis which had not been specially severe is always a reason for solicitude.

Now and then infants are born with consumptive disease. In that case the lungs are always affected; and the symptoms of fever, cough, and wasting usually show themselves within the first three or four months, and the infants almost invariably die within the year. Now and then, however, an infant thus affected may continue apparently in good health for a few months, and then be suddenly attacked by symptoms of acute inflammation or of severe bronchitis which prove rapidly fatal; and it may be found after death that the acute attack destroyed life because the lungs were already the seat of extensive consumptive disease.

No infant in whose mother's family a predisposition to consumption exists ought to be nursed by its mother, but by a healthy wet nurse; or, if that is impossible, it should be brought up on a milk diet, with but a small admixture of farinaceous food.

There is a form of very rapid, or so-called galloping consumption, which is seldom observed before the age of seven years; generally two or three years later. Its symptoms so closely resemble those of typhoid fever, that it may readily be mistaken for it. I refer to it in order to say that the doctor who mistakes the one for the other can scarcely be regarded as blameworthy; and the mistake is of the less importance since the treatment applicable to the one case would do no harm in the other.

I have already noticed the connection between water on the brain and consumption. It is indeed nothing else than inflammation excited by the presence of the deposit of consumptive matter in the brain or its membranes.

Little has been said hitherto about the wasting which was referred to as one of the characteristics of consumption. When the disease is limited, or nearly so, to the lungs, the wasting is not considerable until the mischief in the chest is far advanced. It must be remembered, however, in order to judge of this, that while in the full-grown man the best sign of health is the persistence for years together of the same weight, the case of the child is different. The child ought to grow in height, and increase in weight, and during these changes the plump infant grows thinner, not by real wasting but by conversion of its fat into bone and muscle. The child is thinner, but is taller and weighs heavier. The only real test therefore of the condition of the child is afforded by its increase in height and in weight. One need not be solicitous about the child who increases in height, and maintains his previous weight, nor about him who while he does not grow yet becomes heavier; but the child who neither gains in weight, nor in height, or who loses weight out of proportion to his increased height, is in a condition that warrants anxiety. I have long been accustomed, in the case of children whose parents were resident in India, to instruct those who have charge of them to send every three months a statement of the height and weight of the children, as the best evidence of their state of health.

Consumptive Disease of the Bowels.—Consumptive disease sometimes invades the whole system from the very first, while in other instances it attacks from the outset the organs of digestion, and continues throughout to affect them chiefly, and loss of flesh is then one of its earliest symptoms. In instances where there is a strong family predisposition to the disease, consumption of the bowels or mesenteric disease, or disease of the glands of the bowels, all three popular names for the affection, sometimes shows itself at the time of weaning. In the majority of cases, however, it comes on later, after the completion of teething, and between the age of three and ten years. Indigestion such as I have already spoken of sometimes precedes it, with the irregular condition of bowels, and the patchy state of the tongue. But this is by no means constant, scarcely I think general; and not infrequently momentary, causeless, colicky pains precede for a short time any other symptom. In a few weeks after their occurrence, sometimes indeed independently of them, the appetite fails, or becomes capricious; the bowels begin to act irregularly, being alternately constipated and relaxed; and the motions are unnatural in character, being, for the most part, dark, loose, and slimy. Sometimes indeed, they are solid, and then often white, as if from complete inactivity of the liver, and sometimes half-liquid, frothy, and like yeast. One peculiarity which they always present, be their other characters what they may, is their extreme abundance, quite out of proportion to the quantity of food taken, and due to their admixture with the unhealthy secretions from the bowels. The child next becomes restless and feverish at night, its thirst is considerable, and the colicky pains become both more severe and more frequent. Sometimes the stomach grows very irritable, and the food taken is occasionally vomited, while the tongue, in the early stages of the affection, continues for the most part clean and moist, and except that it is often unnaturally red deviates but little from its appearance in health. Next comes a change in the condition of the belly, the date of which varies considerably. It becomes larger than natural, owing to the filling of the bowels with wind, but at the same time it is tense and tender on pressure—two points of great importance to be noticed, and the glands in the groin, which in a healthy child cannot be felt, become enlarged, and are felt and perhaps even seen like tiny beans under the skin.

As in other forms of consumptive disease, so here the progress from bad to worse seldom goes on uninterruptedly. Pauses take place in its course, though each time they become shorter; and signs of amendment now and then appear, but they too promise less and less with each return. The child wastes rapidly; is always more or less feverish; the abdomen is constantly tender, but does not in general go on increasing in size; the pains become more frequent and more severe, and the bowels are almost always habitually relaxed. Life is sometimes cut short by the lungs becoming affected, but when this is not the case the patient may linger on for weeks, or months, or even for two or three years, until, worn to a skeleton, death at last takes place from exhaustion.

Much apprehension is often needlessly excited in the minds of parents, with reference to any child whose digestion is imperfect, who loses flesh, and has a large abdomen; and the words mesenteric disease, sometimes uttered thoughtlessly by the doctors, seem to them to seal their little one's doom. Now, first of all, it must be remembered that mesenteric disease, due to consumption, plays but a very small part in the production of the symptoms just described, but that the covering and the lining of the bowels are chiefly involved. Next, enlargement of the mesenteric glands and disorder of their functions take place from many causes other than consumption. They are always more or less enlarged in typhoid fever; they become enlarged when irritated by unwholesome food in infancy, or they may swell in the course of chronic indigestion. In all these cases too, the glands in the groin may be enlarged by sympathy, and this without the existence of any actual abiding disease. A big abdomen is, of itself, no evidence of it, nor even when associated with indigestion and frequent stomach-ache; but when to these you add abiding tenderness, and an evening temperature always at least one degree above that in the morning, there is every reason to fear that consumptive disease has attacked the organs of digestion.

Even then, however, there is no ground for despair; for, while consumptive disease in any form is less seldom recovered from in childhood than in after-life, such recovery oftener takes place in cases of affection of the digestive organs than when the disease is seated elsewhere.

Scrofula.—With this word of comfort I leave the subject of consumption, and pass to that of the allied disease scrofula. Briefly stated, two of the great differences between it and consumption are that scrofula is almost entirely limited to childhood and youth, while consumption may occur at any age; and next, that while scrofula attacks the bones and the glands, the skin and the membranes adjacent to it, consumption has its seat in the lungs, the brain, and the internal organs.

Scrofulous diseases of the bones come so exclusively under the observation of the surgeon, that I do not feel myself competent to say anything about them. I would however warn all parents to be very much alive to the importance of noticing the early symptoms of any such diseases, as shown by slight lameness, complaint of pain in the back, or difficulty in moving the hand or arm, or in turning the head or bending the neck. They may be but temporary accidents, due to cold, or to slight muscular rheumatism, or to some sprain not noticed at the time; but they may also be signs of the commencement of scrofulous disease of some bone; and in no disease whatever is early judicious treatment of greater value, or the result of neglect less remediable.

Besides these graver ailments which seldom appear until after the time of infancy has passed, there are others of a less serious nature which often show themselves within the first year of life. One of these consists in the formation beneath the skin of numerous small lumps of a rounded form, and of the size of a kidney-bean, slightly movable, and not tender. By degrees such lumps become adherent to the skin, the surface of which above them grows red, they project slightly above it, and at last open by a small circular aperture, discharge a little matter, and then subside. They collapse and disappear; a slight depression and a degree of lividity of the skin mark for a considerable time the situation they had occupied. I refer to them, because while they are a sign of a scrofulous constitution, which may require special care in diet and preparations of iron and cod-liver oil, they are best left absolutely alone—neither poulticed nor lanced. The same principle of non-intervention applies equally to the swellings which sometimes form on two or three of the fingers in infancy, not involving the joints but producing great thickening and a hard swelling around the bone. These swellings disappear by degrees as the constitutional vigour improves, and this is especially promoted by a long stay at the seaside; but they tend, if the health fails, to affect the bones themselves, and thus to occasion deformities of the hand.

Glandular swelling, discharges from the ear, offensive secretion from the nose, and in female children, even of very tender age, a discharge of whites, are all common signs of a scrofulous constitution, and all tedious and troublesome. They all, however, are very much under the influence of judicious medical treatment. It must at the same time be borne in mind that none of these ailments admit of what may be called active treatment. There are no royal means of dispersing scrofulous glands, or of curing discharges from the ear, or of doing away with the offensive smell which in some cases proceeds from the nostrils. Fresh air, suitable diet, preparations of iron, residence at the seaside, and sea-bathing, measures directed to improve the general health, are of chief value, and without them local treatment is of small avail.

A few words, however, may with propriety be added with reference to the local treatment of the minor ailments to which I have just referred.

No local application is of use in the scrofulous swellings of the fingers. Tincture of iodine, indeed, may be painted over them when quite small, while at the same time the joints are kept quiet by a small gutta-percha splint. When they become considerable, iodine is useless; and even if matter forms in the swelling it is much better to let it make its way out by a small opening spontaneously than to make a puncture with a lancet, since the edges of the wound would not heal, and the risk of the disease affecting the bone would be increased.

The glandular swellings of the neck or about the lower jaw are likewise best let alone, or merely covered with a layer of cotton wool, stitched inside a piece of oiled silk to maintain a uniform temperature. If they become suddenly painful and more swollen, a cooling lotion of Goulard water and spirits of wine, constantly applied, will reduce the swelling and lessen the discomfort. When stationary, a mild iodine ointment may be smeared over the gland at bedtime, and covered with oiled silk. Applications of iodine, however, need careful watching, for sometimes they over-irritate the gland, and cause an abscess. If the gland were out of sight there would be no objection to this, which would probably be a rapid mode of getting rid of the swelling; but the scar left behind, if the abscess burst or were opened, is an objection when the swelling is situated in the neck or at the jaw.

If the skin over the top of the swelling becomes red, and its substance begins to feel soft, then, but not till then, it is desirable to apply a warm poultice constantly. At the same time the progress must be daily watched by the doctor, in order that he may seize the proper moment to make a small puncture and let out the matter. The small cut leaves a less puckered scar than the natural opening. The subsequent management of the case must be superintended by the doctor.

Offensive discharge from the nostrils does not depend, in by far the majority of cases, on disease of the bones, but on an unhealthy condition of their lining membrane. It is exceedingly obstinate and difficult of cure, is four times more frequent in girls than in boys, and unfortunately often lasts into womanhood, and continues even when the general health is perfect.

Much may be done to abate the annoyance by diligent sniffing up the nostrils some weak disinfectant; or by regularly irrigating the nostrils by means of a simple apparatus, to be obtained from any instrument-maker. In spite of this, however, it is often necessary to introduce a little plug of cotton wool dipped in the fluid some distance up the nostrils, with a thread attached by which it can be withdrawn, and a fresh one substituted twice a day.

The discharge of whites is sometimes very troublesome, and apt to return from the commencement of teething up even to womanhood. It is a mere sign of debility, usually also connected with a scrofulous habit, but has no further or graver meaning. Locally, constant cold ablution by means of a sponge held above the child, not touching it, is the great remedy, and this may have to be repeated every hour or two if the case is severe. Astringent lotions of different kinds may be used in the same manner; while care must be taken that the child's drawers are large and loose, so as not to irritate her when sitting. General treatment, however, sea air and sea bathing are especially in these cases the great remedy.

It must not be forgotten that all these ailments have a special tendency to recur; and that when people say 'Dr. A. or Dr. B. did the child good for the time, but this or that symptom returned as soon as the treatment was discontinued,' as though this were the doctor's fault, they are unjust; for the tendency to return of every form of scrofulous disease is one of the great characteristics of the malady. Patience and perseverance on the parents' part, even for months and years, are often as much needed as skill on the part of the doctor.

One more remark may not be out of place. Some persons have an impression that there is something specially shameful in scrofulous disease, and while they will readily admit the existence of a consumptive tendency in their family, they almost resent the suggestion that their child's ailment is scrofulous. For this prejudice there is absolutely no foundation. There is no more reason for connecting scrofula in a child with any antecedent wrong-doing on the part of its progenitors, than there is for attaching that idea to the red hair or black eyes which a child may have in common with the rest of its family.

Rickets.—We sometimes see, especially in the poorer quarters of a great city, persons dwarfed in stature, with large hands, bowed legs, bent arms, swollen wrists and ankles, walking with an awkward gait, though usually holding themselves remarkably upright, with the face of a grown person on the body of a child, and we know that they suffered from rickets when young.

Rickets is essentially a disease of childhood, and of early childhood, in which proper bone-formation does not take place, the soft material, or gristle, which should turn to bone, remaining long in the soft state. When, therefore, the child begins to walk, or to use its limbs, they bend under the weight of the body, or under their own weight, and with every slight movement which its feeble muscular power enables it to make. It does more, however, than interfere with the hardening of the limbs: it arrests growth to a great degree, interferes with development, retards teething, postpones the closure of the open part of the head, or fontanelle, weakens constitutional vigour, and impairs muscular power. To this feeble muscular power it is due that the child cannot make the effort to fill its lungs completely, and hence the pressure of the external air forces the soft ribs inwards, and gives to the chest the peculiar form of pigeon-breast. In the course of time the delayed bone-formation takes place, and the bones themselves become as hard as ivory, but the limbs do not straighten, and the deformity produced in infancy is but confirmed in after-life.

The greater degrees of rickets are scarcely ever seen among the children of the wealthier classes, but over-crowded and ill-ventilated nurseries, cots from which the air is well-nigh shut out by closed sides and overhanging curtains; injudicious feeding, with undue preponderance of farinaceous food, often produce its slighter forms. I never yet saw rickets in a child while brought up exclusively at its mother's breast.

The slighter forms of rickets show themselves in a tardy closure of the infant's head, which sweats profusely when the child is laid down to sleep; in big wrists, which contrast with the attenuated arms; in a general limpness of the whole body, and a bowing of the back under the weight of the head, which bends as a green stick would bend if a weight were placed upon it. They are further marked by backwardness in teething, and by the irregular order in which the teeth appear, and, further, by the peculiar narrowness of the chest, and by what has been termed the beading of the ends of the ribs: little round prominences due to a heaping up of gristle just where the ribs join on to the breastbone, marking the spots at which the tardy bone-making has come to a standstill.

Children who bear these stamps of rickets are far more apt than others to suffer from spasmodic croup, and in them it is also specially likely to be severe and to be accompanied by convulsions. They will also be more liable than others to attacks of bronchitis, they will suffer more during teething, they will be often constipated, and will be troubled by various forms of indigestion. Now and then, too, they will have causeless attacks of feverishness lasting for a few days, or for two or three weeks, attended with general tenderness of the surface, and a disposition to perspiration, which brings no relief but serves only to weaken.

It is true that these symptoms do not often become immediately dangerous to life, though spasmodic croup and bronchitis both have their perils; but they interfere with health, and growth, and good looks, and cheerfulness, and quick intelligence.

If mothers would but ask themselves the real signification of these symptoms, and change the conditions which surround the child, and alter their mode of feeding it, they would many and many a time be spared the heart-ache of seeing their little ones grow up weakly, ugly, ill-thriven.

Unfortunately, it is so much easier to give cod-liver oil and iron than to turn the best spare room into a night nursery, and to uglify the cot by taking away the curtains which made it so pretty, and to give up some of the pleasures of society in order to superintend the preparation of the baby's food; that the doctor is called in to correct by drugs the evil which drugs cannot reach. Iron and cod-liver oil are very useful in the second place; fresh air, good ventilation, and a wise diet must always occupy the first.

Acute Constitutional Diseases.—It still remains for us to glance rapidly at the characters of the acute constitutional diseases, all of which belong, as has already been stated, to the class of fevers. Of them all but two are contagious—that is to say, are capable of being communicated directly from person to person. They are likewise infectious, or, in other words, articles of bedding or clothes which have been worn by the sick, retain a something—an exhalation from the breath, an emanation from the skin, or a secretion from the bowels—which may reproduce the same disease in a person previously healthy.

To this contagious and infectious property there are two exceptions; the one is furnished by acute rheumatism, or rheumatic fever, the other by intermittent fever, or ague.

Rheumatic Fever.—The main features of rheumatic fever are the same at all ages. Fever, pain in the limbs, swelling of the joints, sweats unattended by that relief which usually accompanies abundant action of the skin in fevers, are its characteristics. In the child all these symptoms are usually less even than in the adult. The swelling of the joints in particular is less considerable, and both the pain and the swelling are apt to wander from one to another joint, or to a different limb, instead of remaining fixed as they do in the grown person for several days in the same joint, even though fresh joints may be implicated in the course of the disease.

These circumstances tend to make people look on rheumatic fever in the child too often as a comparatively trivial ailment; and this not only because the suffering which attends the disease is slighter, but because its duration is also shorter. But there is one fact which forbids this low estimate of its importance, and that is the great tendency to affection of the heart even in cases of comparatively mild rheumatism in the child; while in the grown person there is a direct relation between the general severity of the rheumatic symptoms and the liability of the heart to be involved. I have already stated that nine out of ten of all cases of heart disease in early life, not due to original malformation, are of rheumatic origin, and further that heart disease comes on in the course of four out of five cases of rheumatic fever in the child, slight as well as severe. It seldom occurs before the third or fourth day of the illness, so that if parents take the alarm at the very outset, it is usually though not invariably possible for the doctor by judicious treatment to anticipate and to prevent its occurrence, or at any rate greatly to control its progress.

Every threatening of rheumatism, therefore, is to be watched with the most anxious care, since so serious a complication as disease of the heart may accompany extremely slight general symptoms. It is wise too, to place any child in whom general feverish symptoms come on at once under medical observation, for though it does not usually happen, yet it does sometimes occur, that rheumatic inflammation attacks the heart before any other local signs of the malady have manifested themselves. It is scarcely necessary to add that tenfold precautions are needed when rheumatism has once occurred, since the liability to its return is very great, and the heart which escaped in the first attack may suffer in the second; or the comparatively small mischief done the first time may become an incurable disorder.

Ague.—Intermittent fever or ague is very rare in childhood in London; or at any rate it is very rare among children of the wealthier classes. I believe it is everywhere rarer among children than among grown persons, probably because they are as a rule less exposed to those malarious influences which produce it. In the child it generally takes the form of tertian ague, that is to say the attack recurs every second day; one day of freedom intervening between two attacks.

The three stages of shivering, heat, and sweating are less marked in the child than in the grown person, and this indistinctness of its symptoms is greater in proportion to the tenderer age of the child. Shivering is scarcely ever well-marked, a condition of unaccountable depression usually taking its place, while once or twice I have known convulsions occur which gave rise to the apprehension that disease of the brain existed. The hot stage is long, and passes off gradually without the profuse perspiration that occurs in the grown person, and the child even between the attacks is almost always more or less ailing.

A first and even a second attack may puzzle not the parents only, but also the doctor; but after the symptoms have returned a few times, the child being neither better nor worse in the intervals, it becomes evident that no serious disease is impending. The risk of an overhasty conclusion is that the depression and disturbance of the nervous system may be supposed to imply the existence of brain disease; and lead to unsuitable treatment, instead of the administration of quinine, which nine times out of ten proves a specific for ague. The rapid increase of temperature in the attack, and its equally rapid subsidence afterwards, will, if carefully noted, preserve from error.

There is much that is obscure with reference to the nature both of rheumatic and intermittent fever. They differ from other fevers not only by being neither contagious nor infectious but also by their readiness to return, while a single attack of any of the others furnishes a guarantee, and often a complete guarantee, against its recurrence. In addition to these peculiarities, the fevers of which I have now to speak are characterised by running a certain definite course, being accompanied by certain peculiar appearances on the surface (generally rashes on the skin, whence their name of eruptive fevers); being attended each with its own peculiar dangers, and all having a tendency to what is termed epidemic prevalence; that is to say to occur one year, and without obvious cause with vastly greater frequency than in other years.

Mumps.—It has been questioned whether that painful but not dangerous ailment the mumps, ought or ought not to be classed with these fevers. I think it should, for it is contagious, infectious, runs a fairly definite course, is attended with invariable external appearances, often prevails epidemically, and one attack preserves in most instances from a second.
