MODE TO ASCERTAIN THE DISTENTION OF
THE BLADDER.

Insert the greased arm up the rectum, and, when fully advanced, make pressure downward; the dilated bladder will then be under the hand. The best remedies are sulphuric ether and laudanum, which should be given in large quantities. Four ounces of each should, in a quart of cold water, be administered by the mouth: the like quantities, blended with three pints of cold water, ought to be thrown up as an injection. The last being given, the hand should be placed over the opening and pressed upon it for ten minutes. Should one dose not succeed, in a quarter of an hour the injection may be repeated. Again and again it must be had recourse to; till the spasm is vanquished or till the urine flows freely forth.

Should the horse be seized where no medicine can be obtained, then extract blood from free openings till fainting takes place. Several small depletions are very weakening, and a large quantity of the vital fluid drawn at different times is far less likely to overcome the disease than one full venesection. Open both jugulars: allow the blood to flow from both veins till the water rushes forth or the animal falls, when, insensibility being produced, everything like spasm disappears, and the bladder will mechanically empty itself. Should not such a relief ensue, the greased arm may be inserted up the rectum, and gentle pressure made upon the gorged viscus. Advantage is thus taken of the animal's insensibility to adopt a mode of relief which we dare not hazard while consciousness is retained.

CALCULI.

Stones within the urinary apparatus are designated by various names, that are derived from the situations in which they are found. Thus renal calculus represents a stone which has been discovered within the pelvis of the kidney. Uretal calculus implies a stone found within the tubes leading from the kidneys to the bladder; but calculi of this kind are as yet unknown in the horse. Cystic calculus signifies a stone which resides in the cavity of the bladder. Urethral calculus denotes a stone which was detected within the passage leading from the bladder. Of these the cystic are altogether the largest, and the renal, at a considerable distance, rank as the next in magnitude. All consist of carbonate of lime or of common chalk, held firmly together by the secretion of the mucous membrane.

The symptoms which characterize renal calculus are not well marked. The urine may become purulent, thick, opaque, gritty or bloody. Exertion may provoke extreme anguish, resembling a severe fit of colic; but the attack is distinguished from genuine gripes by the back, during the pain, being always roached. However, the most decided symptom is of a negative nature; being the absence of stone in the bladder to account for the diseased urine. The inference is, moreover, strengthened if, when the hand within the rectum is carried upward, pain and alarm are elicited; or if pressure made upon the loins causes the animal to shrink.

Cystic calculus is denoted, as is the previous kind of stone, by certain conditions of the urine. Added to these general signs, the water, when flowing forth, will often be suddenly stopped, and every emission is followed by violent straining. Abdominal pains also are present; but the back is rather hollowed than roached. The point of the penis is, in particular instances, constantly exposed; and the horse, when going down hill, sometimes pulls up short, either to recover from torture or to relieve the bladder.

A CERTAIN METHOD OF ASCERTAINING IF
THERE BE CALCULUS IN THE BLADDER.

The way to ascertain the presence of cystic calculus is to make an examination per rectum. Make the investigation with all gentleness. The foreign body may then be distinctly felt; even its size, form, and irregularities can by this means be discovered.

Urethral calculus is a small stone which, during the flow of urine, has been carried out of the bladder and is spasmodically grasped by the muscle of the urethra. The passage is effectually closed and great suffering is induced. Should the stone be impacted within the exposed part of the canal, the precise situation is easily told. Behind the stoppage the passage is distended by fluid; while before it all is natural. The calculus should be cut down and removed; the wound being afterward dressed with a solution of chloride of zinc—one grain to the ounce of water. This is an easy and by no means a dangerous operation. Any person of ordinary skill having a sharp knife may undertake it.

For renal calculus little can be done. That little, however, consists in mingling two drachms of hydrochloric acid with every pail of water, and allowing the animal to imbibe as much as it pleases. Should the medicated drink be refused, the horse must be starved into accepting it. With this liquid, however, the stone must be small to be dissolved; but it effectually checks the further increase of the calculus.

Lithotomy is the name given to that operation by which large stones are removed from the bladder of the horse. It is far too complicated and too serious a proceeding to be entrusted to any general reader. No direction which possibly could be misconstrued shall, therefore, be attempted. When an operation is required for stone in the bladder, a qualified veterinary surgeon had better be employed. Mr. Simmonds, of the Royal Veterinary College, Camden Town, however, deserves praise for having invented an instrument by means of which stone can generally be removed from the bladder of the mare without resort to the knife being necessary.

HEMATURIA, OR BLOODY URINE.

The name fully characterizes this affection. The blood emitted may consist of small clots; it may congeal after it has left the body; or it may be entirely mingled with—giving a brownish tinge to—the water. Upon the exhibition of this disorder, always treat the symptoms first; when all chance of immediate danger has disappeared, examine the body to ascertain whence the hemorrhage proceeded, because in this affection the symptoms really constitute the disease; and when the first has disappeared, the last is cured.

A HORSE SUFFERING FROM HEMATURIA, OR BLOODY URINE.

The extent of the bleeding, of course, regulates the symptoms. When that is copious, the breathing is short and quick; the pupils of the eye are dilated; the pulse is not to be felt at the jaw; the head is pendulous; and the visible mucous membranes are cold as well as pallid. Lifting the head produces staggering; if continued, the animal would fall. The back is roached; the flanks are tucked up, and the legs widely separated, as though the horse was aware of its inability to support its body.

The treatment consists in disturbing the sufferer as little as possible; in acting upon the report received, for in a case of this kind it is hardly credible there should be any mistake. Administer, as gently as it can be done, two drachms of acetate of lead in half a pint of cold water, or as a ball, if one can be delivered. If this has no effect, in a quarter of an hour, or sooner should the symptoms demand haste, repeat the dose, adding, however, one ounce of laudanum or two drachms of powdered opium. Give two more drinks or balls of the like composition; but should these be followed by no beneficial result, change the medicine after the administration of one ounce of acetate of lead.

When the indications are not alarming, the horse may be left for a couple of hours, with strict orders that the animal be watched, but on no account disturbed. Should, however, activity be required, obtain some of the coldest water, and have several pailfuls dashed from a height upon the loins. After this inject some of the same fluid, allowing the water to flow freely forth from the anus—the object only being to procure the advantages of excessive cold. For medicine, a trial may be made of the ergot of rye. Pour on to four drachms of the drug half a pint of boiling water, and, when cold, add one ounce of laudanum and four ounces of dilute acetic acid—not vinegar, as that always contains sulphuric acid, which would counteract the action of the lead. Two drinks, two enemas, (each lasting twenty minutes,) and any quantity of water upon the loins will serve for the second hour.

If these remedies have produced no change, all further treatment must be suspended for eight hours, at the expiration of which period the treatment may be resumed, and the previous measures repeated.

Should the hemorrhage have ceased, leave the horse undisturbed for the night. On the following day, if no blood has been noticed, have the animal gently led under cover. Then proceed to examine the horse per rectum. If the kidneys are not enlarged, hardened, or sensitive, and if the bladder is without stone, but of its natural thickness, there is every prospect of a favorable termination.

Should the bladder be thickened, adopt the treatment laid down for cystitis; if stone is discovered, an operation is indicated; be the kidneys disorganized, the case is hopeless. If none of these are present, then any of the following medicines may be experimented with, it always being uncertain which will prove beneficial:—

Extract of catechu In one-ounce doses daily.
Strong infusion of oak bark Three pints daily.
Alum One ounce daily.
Sulphate of iron or of copper One ounce daily.
Muriatic acid Six drachms daily.
DIABETES INSIPIDUS, OR PROFUSE STALING.

In this affection, which, properly treated, is but a passing annoyance, the thirst is enormous; but more fluid is voided than the animal drinks. The strength and condition are quickly lost, while the flesh fades rapidly away.

Either the horse has been tampered with by the groom, or the hay, oats, or beans are unsound. A sudden change of water is said to produce the disorder; but that, probably, is far more a stable excuse than an established cause. However, change both food and water. Take into the stable two slips of blotting-paper. Dip the ends of them into some of the urine, which will always be retained in the interspaces of the brick flooring. Smell one piece. If it communicates a scent resembling violets, that is proof positive turpentine has been administered. Dry the other piece. Should that, when perfectly dry, and a light is applied, prove to be touch-paper, the evidence is conclusive: "sweet niter" has been secretly given to the animal. Should both these tests fail, the groom is innocent, as other diuretics are unknown in the stable.

The horse should not be taken out while the prominent symptom lasts; it is languid; is unfit for work or even exercise. No brutality can quicken the body when the vital powers are exhausted; but inattention to the suggestion of mere humanity may change a slight and temporary evil into a severe and critical disorder—nephritis.

A pail of good linseed tea, made by pouring boiling water on whole linseeds, and afterward allowing the infusion to stand till lukewarm, should be constantly before the manger. The animal may drink according to the dictates of its condition. The linseed, when strained off and mixed with sound bruised and scalded oats, may be given as food. No hay or grass should be allowed. Attend to the grooming, although it is a sick horse and does not go out. Nothing relieves the kidneys more than the restored action of the skin. A ball may be given every day. It should consist of—

Iodide of iron One drachm.
Honey and linseed meal A sufficiency.

Or, should a drink be preferred, dilute—

Phosphoric acid One ounce.
Water One pint.
Give night and morning.  

The author was once prepossessed in favor of iodide of potassium for the cure of diabetes. He is indebted to Mr. Woodger, the excellent practical veterinary surgeon of Paddington, for a knowledge of the very superior efficacy of the drug just named. It exercises a potent action over the kidneys, at the same time it is a first class tonic, and in a surprising manner reduces the desire for fluids. It is in all respects the exact medicine which could be wished for in a case of diabetes insipidus.

ALBUMINOUS URINE.

Two cases of this description occurred in the extensive practice of the late William Percivall, Esq. They are narrated in the admirable work entitled "Hippopathology," bequeathed to posterity by the estimable author. The present writer having been honored by the friendship of the gentleman named, is, from frequent conversations upon the subject, the better able to describe and to depict the disorder.

THE POSITIONS ASSUMED BY HORSES HAVING ALBUMINOUS URINE.

The positions of both horses were remarkable. One stretched the fore and hind legs out, as though it were about to urinate; the other roached the back and brought the hind feet under the body as far as possible. Turning in the stalls was, in each case, accomplished with difficulty; and the straddling gait remarkable in both, indicating the seat of the affection.

Some urine being caught by the groom, it was thick but clear—like melted calves' foot jelly—and, when cold, the surface was uneven. Bichloride of mercury being added to a portion of the fluid, caused a thick, colorless, opaque substance—resembling coagulated white of egg—to be thrown down, leaving a clear straw-colored liquor above the settlement. Another portion being first treated with acetic acid, afterward mixed with prussiate of potash and subsequently boiled, became in appearance like to milk. With time, however, a white sediment occurred, leaving the fluid perfectly clear.

Mr. Percivall's treatment was mildly depletive. He bled moderately, gave a laxative, and applied mustard to the loins for a brief space. Perfect rest, strict attention to diet, and repeated doses of opium, constituted the after-measures. It is also mentioned that diuretics, tonics, and stimulants were tried, but all proved injurious. Both animals ultimately recovered.


THE TESTS FOR ALBUMINOUS URINE.

A. The appearance of the urine when cold, being partially rough on the surface. Sometimes, however, the fluid is merely thicker than usual, appearing like water in which a portion of gum has been dissolved.

B. The white precipitate produced by the addition of a portion of the solution of bichloride of mercury.

C. Some urine to which a little acetic acid was first added. A portion of the solution of prussiate of potash was subsequently introduced. The liquid was then boiled, when it became thick, white, and opaque, like milk.

Those who desire ampler details are referred to "Hippopathology," by W. Percivall, published by Longman & Co.


CHAPTER X.

THE SKIN—ITS ACCIDENTS AND ITS DISEASES.

MANGE.

This troublesome disease, which is the itch of the stable, generally preys upon the poorly nurtured, the aged or the debilitated. Neglect is the almost necessary associate of poverty; loss of pride attends loss of means, for seldom can the spirit of man brave the frowns of fortune. The want of emulation is always seen most emphatically without the doors of the home; the garden denotes the failure of industry, and the stable languishes under an absence of activity. The grooming is avoided; the horse's food is proportioned to the master's means, and is not given at regular hours; coarse diet and a filthy abode generate that weakness which will assuredly breed mange.

SYMPTOMS OF MANGINESS WHEN CAUGHT IN THE FIELD.

The disease, once developed, is highly contagious; all horses standing near the one affected, all that may touch it, or the shafts to which it was harnessed, or anything that has been in contact with the contaminated body, are inoculated. The very robust, to be sure, may escape; but this circumstance is to be regarded as the most stringent test of actual health rather than as the declaration of that state which the majority of mankind are pleased to term perfect condition. The animal which escapes must be of so sound a body as to afford no nutriment to the disorder which preys upon debility. Probably not one horse in ten thousand could resist so searching a test; the trial, however, after all, would be no more than a negative proof; and it is to be much regretted that science, up to the present time, has not discovered any means by which the presence of established health can be demonstrated.

Mange depends upon the presence of an insect which is classed with spiders, though to the uninitiated it looks, under the microscope, far more like a deformed crab. A representation of this parasite, very highly magnified, is here given, from Dr. Erasmus Wilson's paper upon the subject; and the reader may indulge his ingenuity by discovering its likeness to the spider.

THE MANGE INSECT.

The parasites are, when attentively searched for, to be recognized by the naked eye. Any man, by scratching the roots of the hair upon the mane of a mangy horse, may loosen a portion of scurf; let this scurf be received or cast upon a sheet of white paper. The paper then should be subjected to a strong light; the glare of the noonday sun is to be preferred, as warmth greatly influences the activity of the parasites. Numerous very small shining points may thus be seen moving about the mass in all directions. Those points are the insects, and, considering the easy means we now possess of demonstrating their existence, it seems astonishing that veterinary science was so long before it recognized the true source of the contagion. Even at the last moment, the sight was quickened by the research of a human physician, Dr. Erasmus Wilson; but after that gentleman soon followed Mr. Ernes, veterinarian, of Dockhead.

Mange would be far less general than it is, did not the convenience or the prejudice of mankind predispose them to favor a "run at grass." The horse there placed is all at once taken from a stimulating diet, while, the groom being relieved of his charge, foulness accumulates upon the coat. The animal, instead of standing still and feeding upon nourishing provender, has to travel far and to distend the stomach with a watery substance before the cravings of hunger can be appeased and satiety impress the creature with a consciousness that existence has gathered a sufficient support. The quadruped while at grass is necessitated to be eating the major portion of both day and night; little leisure is left from the cravings of appetite for rest or for repose. No comfortable bed is placed beneath the jaded limbs. There may be an open shed under which all the inhabitants of the field are free to shelter themselves from the storms of autumn and from the colds of early morning. That building is, however, generally taken possession of by horned cattle, or by the victor of the steeds, and none but favorites are allowed to share the comfort of the tyrant.

It is assuredly true that the horse, in its primitive state, must have galloped over the plains free from human care and without a roof to harbor it. In a similar state man also must once have existed. The early Britons are described as walking about in painted costume, and as living on acorns and wild berries. Which of her Britannic Majesty's present subjects would like for six weeks in every year to return to the habits of our ancestors? The horse is even more artificial than man himself. It proves nothing, therefore, that the creature has existed upon the plain; any more than the possibility of rearing human beings apart from civilization can establish that the latter mode is beneficial to the body's development. Man has lost the desire for a wild existence. Then, why is the horse expected to be benefited by a return to the so-called natural state, although securely fenced from that freedom and extent of choice which primitive nature would have afforded?

Horses, when huddled together, often commit fearful injuries upon their companions. The creatures are unused to the society into which they are forced, and awkwardness is apt to be rude. Any want of manners in the heels of a horse is a serious business. But, to put upon one side so weighty an argument against the grass field, as foreign to the present subject,—all sorts of animals are there congregated. Some are turned out "to regain condition;" some to become "fresh upon the legs;" and some to live cheaply till their services are required. Others are allowed "a run," after some virulent disorder; and others merely to afford time for the eradication of obstinate disease. The pony, the cart-horse, the thorough-bred, and the roadster,—all are crowded together. All sizes and conditions meet as at a common table. Is it very wonderful, or much out of the scope of ordinary probability, if one of the creatures so exposed, so fed, and so tended, should engender mange? A few years back, the children kept at Yorkshire schools were much exposed to a similar affection. Those babes, however, had not been more accustomed to cleanliness than the horse, nor were they exposed to half the neglect which the animal at grass is obliged to endure. Is it then surprising that the lower creature should breed a disease like to that which afflicts the human being? Let mange appear in one, and the rest are prepared by exposure and unwholesome food to imbibe the disorder; the contagion rapidly spreads; posts and rails are loosened or overthrown by horses rubbing against them; or, should such things be wanting, constant irritation instructs instinct, and the miserable animals scrub one against the other in the open space.

Besides the grass field, foul lodging or filth and poor provender will breed mange in the horse, as the same causes operating upon the human subject will engender a like disorder. It is sad to think that with the horse, as years increase, ailments accumulate and strength departs; it is sad to think, that as the animal's life becomes more hard to sustain, its food is always the less nourishing and its labor the more exhausting; that as care is necessary, so is neglect encountered; that the wretched quadruped at length is sold to some costermonger, who, when he makes the purchase, nicely calculates how many days of labor the emaciated life is capable of before it is turned over to the knacker. Many a nobleman must have looked upon an animal in the last stage of a weary life which was formerly the companion of his pleasures. The rusty, lean, and worn-out carcass most probably was not recognized, or how must reflection have whispered that power was not given to turn away existence into wretchedness after willfulness had rendered the body less capable of sustaining suffering!

In the vast majority of cases this disease first appears in the mane, among the hairs of which a quantity of loose, dry scurf is perceptible. Before such a sign, however, is to be recognized, excessive itchiness is exhibited. The disease, once established, soon extends to the head, to the neck, to the withers, to the sides, to the loins, and to the quarters; only in very exceptional cases are the legs exposed to its attacks. As the disorder proceeds, the hair falls off, leaving vacant places upon the body; these have a peculiar, dry, acrid, and irritable appearance; they suggest that portions of the body have been scorched with quick-lime, so irregular, patched, and scabby are the parts just referred to. The integument in these places greatly thickens and is no longer soft and pliable as a lady's glove, but becomes corrugated or thrown into well-defined folds.

The hairs, however, are not all removed; a few and only a few remain; these cling with exceeding tenacity to the surfaces which their fellows have quitted. The force required to pull out one of these remaining hairs is somewhat surprising, and the hair being extracted, the roots, upon close examination, will be discovered enlarged and far more vascular than is usual.

The above are the broad and more obvious indications of mange. However, should the diseased locality be more minutely inspected, a number of small pimples are discerned; these elevations are clustered upon different spots. As they mature, the point of each contains a very slight quantity of gelatinous fluid; the vesicles ultimately burst; the contents exude and become dry through the absorption of the atmosphere, forming incrustations upon the surface. Add to this, the irritation provokes the diseased animal to scrub itself against any irregular, projecting surface which may be at hand. Raw places, frequently of magnitude, are often occasioned by the friction so rudely applied; from this source another set of crusts spring up. The places which are denuded, therefore, may present a very varied aspect, but still the parched appearance of the scurfy and dry skin affords the best external evidence of the presence of mange.

A MANGY PIECE OF SKIN.
THE HEAD OF AN OLD, MANGY WHITE HORSE.

An animal, which from being gray in youth has grown white with age, still retains to its death the signs of its youthful color upon its skin. The integument is dark, although the hair may have lost the last vestige of its original hue; the checkered appearance established by mange gives to the white horse a particularly ragged and dejected aspect.

THE TEST FOR MANGE.

Unfortunately, man is not, at the present moment, sufficiently enlightened to recognize the symptoms which indicate an approaching attack of mange; but the animal energetically announces the malady so soon as the contamination is established. The disorder being confirmed, its existence is readily ascertained; the fingers have only to be inserted among the roots of the mane, and the part titillated with the nails. The horse thus treated will stretch forth the head and neck, will compose its features into an expression of excessive pleasure, and will continue motionless so long as the hand remains upon the crest.

This sign, being witnessed, may be esteemed conclusive. Let such an animal be placed in the sunshine for an hour, should the weather permit; otherwise allow it to stand in the warmest house which is unoccupied; then have the coat thoroughly dressed or whisked, until all the loose scurf and incrustations are removed; afterward have the following ointment well rubbed in. Mind the man who whisks the horse goes near no other animal for eight and forty hours. See that every portion of the skin, from the tip of the nose to the point of the tail, is anointed; mark that no crevice or irregularity escapes, from the bottom of the coronet to the apex of the ears.


Liniment for Mange.

Animal glycerin Four parts.
Creosote Half a part.
Oil of turpentine One part.
Oil of juniper Half a part.
Mix all together, shake well, and use.  

It is impossible to state accurately how much will be required to dress the horse—the disease, the coat, and the size vary so materially in different animals. About one pint and a half is, however, the general quantity employed for one application; every portion of the coat must be saturated, and in that condition the animal should be left till two clear days have expired. Thus, supposing the liniment to be used upon a Monday, it is left on until the following Thursday. Then have the surface washed with soft soap and warm water; dry the body and allow the animal to stand in a warm spot as before, so that every portion of moisture may evaporate. Afterward employ the whisk as has been previously directed; subsequently repeat the anointing. That operation must be again gone through for the third and last time after two clear days have once more expired, when the disease ought to be cured; all the insects should have perished, and the skin have been benefited by the stimulation to which it has been subjected.

There are many preparations employed to cure mange. All have some repute, though all (save that already given) are attended with some danger. The author, however, will recite two, at the same time warning the reader that neither of those which follow can be sincerely recommended.

Ointment for Mange.

Strong mercurial ointment Three ounces.
Soft soap One pound and a half.
Mix.  


Wash for Mange.

Corrosive sublimate One drachm.
Spirits of wine One ounce.
Tobacco (made into an infusion) One ounce.
Hot water (which is to be poured into the tobacco) One quart.
Dissolve the corrosive sublimate in the spirits of wine. Soak the tobacco in the boiling water. When cold, mix.

The question has been much debated, "whether man can derive the itch from an animal?" Imaginary proofs favoring the possibility are every now and then confidently promulgated; but all doubts seem to have been put to rest by the investigations conducted by M. Bourguignon. That gentleman demonstrated the unfitness of one creature to support the parasite generated by another. Horses may be violently irritated by insects bred by fowls; but, remove the birds, the supply ceases, and the irritation dies away. So an individual handling mangy horses may get some of the acari upon him and cause vexatious itching; but let the man keep away from the contaminated stable and the sensation is quickly lost. The repeated and repeated renewal of the pest gives a seeming warranty to the popular belief. Certain disorders assuredly are communicable throughout every species of life, as though to prove to the stubbornness of mankind that all nature is akin. Such are hydrophobia in the dog, and glanders in the horse; were all affections, however, equally interchangeable, the inhabitants of this world would speedily become one breathing mass of disease.

PRURIGO.

This affection may lead many a gentleman to imagine his horse has caught the mange; the leading symptom in each disorder is the same. Excessive irritability of the skin is, in prurigo, generally exhibited during the spring of the year; the animal will rub itself with a fury which often removes portions of the coat, but which never exposes the dry and corrugated patches that characterize genuine mange.

THE PROOF OF PRURIGO.

It is very annoying to behold the horse, when in the stable, scrubbing its neck upon the division to the stall; it is provoking to witness the animal leave its corn for the same employment. It excites the fancy of the master and conjures up the dread of every cleanly horse proprietor; the symptom is, however, easily eradicated. It only denotes heat of body; let a portion of the hay be abstracted and a couple of bundles of cut grass be allowed each day; let a mash be given night and morning, until the bowels freely respond, and, without further measures, the annoyance usually ceases.

The irritation may not, however, subside so quickly as shall be desired; to hasten its departure, either of the annexed may be applied externally:

Washes for Prurigo.

Animal glycerin One part.
Simple water or rose-water Two parts.
Mix.  
   
Sulphuric acid One part.
Water Ten parts.
Mix.  
   
Creosote One part.
Oil Eight parts.
Mix.  

Either of these probably will answer, but the writer strongly recommends the first; at the same time it is well to try and reach the source of the disease, or to improve the blood. For this purpose the following drink should be given every night after the last meal:—

Drink for Prurigo.

Liquor arsenicalis One ounce.
Tincture of muriate of iron One ounce and a half.
Water One quart.
Mix, and give half a pint for a dose.  

A week after the irritation has subsided, all medicine may be withdrawn; but it is always well to see that a sufficiency of exercise be given, and to allow an extra feed of oats with a pot of porter every day. These last will restore the strength; for every form of disease is to be regarded as the most emphatic testimony of weakness.

RING-WORM.

This affection at first is simply a disfigurement; but, if neglected, it becomes a troublesome disorder. In the primary instance, the hair falls off in patches, leaving visible a scurfy skin; some say there are pimples under the scurf, but the author must confess he was unable to discern them in those cases which he examined. The scurfy particles, however, are somewhat large, and resemble, in no little degree, the scales which form the bulk of bran. At first, these pieces or flakes of cuticle cover the entire surface; but ultimately they congregate upon the circumference, which, by their numbers, is made to assume a raised appearance. Should the ring-worm not be attended to, the outward margin at last begins to ulcerate, becoming the more difficult to eradicate in proportion to the time of its continuance and the extent of the ulceration.

A REPRESENTATION OF A RING-WORM
ON A HORSE.

For the cure of ring-worm, a rigid attention to cleanliness is imperative; the parts should, at all events, be washed night and morning with mild soap, and hot, soft water; to the places—these having been rendered perfectly dry—one of the following preparations must be applied and laid rather thickly upon the denuded spot:—

Ointments for Ring-worm.

Animal glycerin One ounce.
Spermaceti One ounce.
Iodide of lead Two drachms.

Rub the glycerin and spermaceti together, and, when thoroughly incorporated, add the iodide of lead, or use any of the appended:—

Nitrate of lead Two drachms.
Simple ointment Two ounces.
Mix.  
Oil of tar Half an ounce.
Simple cerate One ounce.
Mix.  
Creosote Two drachms.
Simple cerate One ounce.
Mix.  
Oil of juniper One drachm.
Simple cerate One ounce.
Mix.  

Besides the above, which are not one-half of the remedies in general use, some parties are loud in the commendation of a saturated solution of a sulphate of iron. Others are strongly prejudiced in favor of pure liquor plumbi; another class protest they employ nothing but compound alum water, which invariably and speedily affords relief. There are people who regard a strong infusion of tobacco as a charm for ring-worm; while another set will hear of nothing for that purpose but hellebore ointment.

The author, however, has always employed the first preparation, which, in his hand, has never occasioned disappointment. It has, however, always been aided by the following drink, administered every night. No medicine could possibly act better than those here proposed; they seem to go directly to the skin; but as the state of the integument may be accepted as evidence with regard to the condition of the entire body, a most powerful alterative may not, in this instance, be out of place.

Drink for Ring-worm.

Liquor arsenicalis One ounce.
Tincture of the muriate of iron One ounce and a half.
Water One quart.
Mix, and give every night half a pint for a dose.  

This drink must be continued till every vestige of the disease has disappeared. However, it frequently happens that, after the central bare spot has been cured, ulceration remains about the circumference. Treat this with either of the following lotions:—

Permanganate of potash Half an ounce.
Water Three ounces.
Mix, and smear gently over the part six times daily. Or—  
Chloride of zinc Two scruples.
Water One pint.
Mix.  

The ulcers should be punctually moistened with the last preparation at the periods already stated, and the horse should be thrown up during the treatment. The food should be of the best, and a month ought to be allowed for the cure.

SURFEIT.

Old practitioners generally entertain very false opinions concerning the importance of surfeit; they being inclined to employ more stringent measures for its eradication than the real nature of the disease demands. The affection is rather annoying than dangerous; it makes its appearance suddenly, and seldom involves the entire body. It is a sudden rash or a quantity of heat spots bursting out upon the skin; the spots are round, blunt, and slightly elevated; they resemble the blotches which, during hot weather, often appear upon the human countenance, only the horse's integument being so much more active than the skin of man, the outward affection in the animal may be regarded as proportionably the more severe. Frequently, during the eruption, the pulse is tranquil, the spirit and appetite being good; when such is the case, the lumps mostly disappear in a few hours. Still the food should be looked to; about eight pounds of hay should be abstracted and two bundles of cut grass allowed per day; the corn should be kept up or even increased, and a handful of sound, old beans, which have been properly crushed, should be mingled with each feed. The stable should be airy, and the following drink should be given every day for a month:—

Liquor arsenicalis One ounce.
Tincture of the muriate of iron One ounce and a half.
Water One quart.
Mix, and give once daily, one pint for a dose.
A HORSE AFFECTED WITH SURFEIT.

Should the horse be young, and have been neglected throughout the winter, a surfeit sometimes appears which is of a different character. The lumps do not disappear; but an exudation escapes from the center of each. The constitution is involved in this form of disease, and the malady, if unattended to, is apt to settle upon the lungs.

Should the attack assume the last appearance, on no account take the animal out, not even for exercise. Attend to the perfect cleanliness of the bed, and keep every door and window in the stable open during the day. Feed as directed for the previous form of surfeit, and allow two or three bran mashes whenever the bowels appear constipated; but do not give mashes after the constipation is removed. The desire is not to weaken the system by purgation, but simply to relieve the body; administer the drink recommended above only, giving one night and morning, but, should the appetite suffer, reduce the quantity, or withhold all medicine.

Clothe warmly; bandage the legs, and remove from the stall to a loose box; if the pulse suddenly sink, two pots of stout may be given at different times during the day. If the appetite is bad, good gruel instead of water must be constantly in the manger; cut carrots, if presented a few at a time, will generally be accepted. However, with all such care, a very speedy termination is not to be expected; nature is casting forth something imbibed during a winter of neglect, and no art can quicken the process. The shortest cases of this kind mostly last a fortnight, during which time the treatment, and the entire treatment, merely consists in good nursing and in liberally supporting the body.

HIDE-BOUND.

Strictly speaking, the condition signified by the above term is not so much a disease as the consequence of exposure, of poor provender, and of neglect. Thrust a horse which has been accustomed to wholesome food and a warm stable, thrust such an animal into a straw yard and leave it there through the long and severe winter of this climate. Let the creature which has been used to have its wants attended to and its desires watched—let it for months exist upon a stinted quantity of such hay as the farmer cannot sell—let it go for days without liquid, and at night be driven by the horns of bullocks to lie among the snow or to shiver in the rain—let an animal so nurtured be forced to brave such vicissitudes, and in the spring the belly will be down, and the harsh, unyielding skin will everywhere adhere close to the substance which it covers.
