Such are the outward signs of a weak hoof; but if the person beholding that sort of foot be in any doubt, let him lift it from the ground and inspect the sole. That part will also present peculiarities which can hardly fail to attract attention.

The sole of a weak foot has a thin and irregular margin of crust; a flat surface; well-developed bars, and a healthy frog. Creatures with this kind of hoof, when brought to work upon hard roads or London stones, are apt to throw the foot down with heedless force at every step, and thereby soon to bruise the sole. These horses generally have high action, and this circumstance lends additional force to the blow; the injury reaches the coffin-bone, which begins to enlarge, and ultimately forces the horny sole outward. A pumice foot has the appearance of the member represented on the next page, though the reader must not anticipate the illustration will accurately indicate every stage of the disorder.

Feet of the above description generally have very weak and brittle crusts; but the frog almost invariably is large and prominent; there is no kind of foot which so generally exhibits a healthy frog, and the next page shows an engraving of the ground surface of a pumice foot, in illustration of the fact.

There are many methods proposed for amending a pumiced foot. One is the removal of the shoe; then allowing the deformed foot to stand a certain portion of time upon flat flag-stones. But as stamping the foot upon stones produced pumice foot, prolonged stress thereon does not seem calculated to remove the deformity. A pumice foot is not a lump of pudding, to be flattened by simple pressure. In the horse's hoof there is bone and flesh to operate upon. Even supposing the standing upon flag-stones was beneficial, what immediate result could be anticipated from a medicine which was to be administered once in three weeks, and for half an hour only at each application?

Another artifice is to draw a hot iron over the sole at every shoeing. The intention is to stimulate the horn and thus render the sole of greater thickness. But that which may affect the secreting membrane of the foot may also stimulate the bone to which that membrane is attached. Thus the intended remedy may turn out to be a positive aggravation. There are also other methods of intended relief, but all are equally useless.

The only means of real benefit lies in the treatment of the hoof and in the mode of shoeing. For the last, select what is denominated a "dish" shoe; that is, a bar shoe, having the web hollowed out like to the sides of a pie-dish. The only part of this shoe which touches the ground is the rim of the inner circle.

This kind of shoe will protect the bulging sole, and if shod with leather, the protection will be greater, though the shoe will, in that case, be more difficult to retain. The flat surface at the posterior part of the shoe presents a point for the bearing of the frog, which can afford almost any amount of pressure. The many nail holes made around the shoe denote the difficulty the smith encounters when fixing a protection of this sort upon the pumiced hoof. The crust of the foot is always brittle, and the weight of iron employed being greater than usual requires an extra number of nails to fasten it securely. The smith consequently, in such cases, has no choice. He must drive a nail wherever he can find the horn which will sustain one.

With regard to the horn, keep that continually dressed with equal parts of animal glycerin and tar. Moisten the hoof with this mixture twice a day. No improvement may be remarked in a week; but in two or three months the crust will have become perceptibly less brittle, and the labor of the smith will be rendered far less perplexing. For the abnormal condition of the foot—that is permanent and nothing can be done beyond employing such artifices as are calculated to relieve the affliction.

SANDCRACK.

Any cause which weakens the body of the horse by interfering with the health of its secretions may induce sandcrack. Treading for any length of time upon ground from which all moisture is absent, by rendering the horn hard or dry, may cause the hoof to be brittle and give rise to sandcrack. However, this last provocative seldom operates in this country; when sandcrack occurs in an English horse, it is generally generated by debility, which leads to the secretion of faulty horn. So far, however, is this from being the prevailing opinion, and so little sympathy does the horse receive in its diseases, that the endeavor, indeed the custom, of all veterinary surgeons is to continue at work the horse having a division running completely through the hoof.

Sandcracks are of two sorts. Quarter crack, which chiefly happens among the lighter breed of animals; toe crack, which occurs principally with cart-horses, and mostly with those which work between the shafts.

Quarter sandcrack is of the least importance of the two. It is oftenest seen upon the inner quarter of the hoof, where the horn, being thinnest, is most subjected to motion. Usually it commences at the coronet, extending to the sole, and also to the sensitive laminæ.

A horse thus affected should be thrown up; should be placed in a large, loose box, and receive soft, nutritious food, such as boiled oats, boiled linseed, and scalded hay. A little green-meat occasionally should be allowed to regulate the bowels; greased swabs should be placed over the hoof and under the sole. A bar shoe should be worn upon the affected foot. This treatment should be continued till the horse has recovered from its debility.

With regard to the crack itself, take a fine knife and gradually scrape off the sharp edges till the division assumes the appearance of a groove. If the crack does not reach through to the flesh, no fear need be entertained concerning the lower edges of the crack, because the horn secreted by the laminæ is of a soft nature, and will most readily yield. Besides, paring the outer horn often prevents the inner layer being cracked by the motion of the foot; this being done, should the division not descend the entire length of the hoof, or reach from the ground to the coronet, with a firing-iron, heated to redness, draw a line at each extremity of the fissure. The line need not be made so deep as will occasion pain; it is only necessary that the mark should go through the hard outer crust of the foot to prevent extension of the division.

Should the separation be the whole way down the hoof, it is as well to adopt either the plan followed by the late Mr. Read, or the mode pursued by Mr. Woodger, the clever practical veterinarian, well known in Paddington. Mr. Read used to make a semicircular line near the coronet with the hot iron: Mr. Woodger has for years been accustomed to draw lines from the coronet to the crack in the shape of a V, with the same instrument. Both methods have a like intention, namely, to cut off the coronet from the inferior portion of the hoof, thereby preventing the movements of the foot from operating upon the newly secreted horn. However, Mr. Woodger's plan being the easiest, and quite as effective as that of the late Mr. Read, is certainly the best.

Sandcrack, when it occurs at the toe, usually extends the entire length of the foot, and leaves a portion of bleeding flesh exposed. The laminæ, being opened to the stimulating effects of the air, are very apt to throw out a crop of luxuriant granulations. These, of course, are pinched between the two sides of the division. They bleed freely; often, from the pressure, they turn black, and then smell abominably. The putrid action, having once commenced, is apt to extend, and portions of the coffin-bone are likely to exfoliate.

Now to prevent this, so soon as the horse is brought in with a sandcrack, wash the part thoroughly with the chloride of zinc lotion, one grain to the ounce of water. The bleeding having ceased, pare down the outward edges of the separation, and put on a bar shoe, eased off at the toe, and with a clip on either side of the division. If the injury has not extended the length of the hoof, you must make a line at each extremity with a heated iron, as in quarter crack, than which it is also of more consequence that the coronet should be isolated; because the external horn being thickest at the toe, is the more likely by its movements to be influential upon the new and plastic horn of the coronet.

Should, however, the granulations have appeared, and the horse, with appetite lost and the head dejected, the pulse thumping and the injured foot held in the air, appear the picture of a living misery, first cleanse the wound thoroughly with the chloride of zinc lotion. Then apply a firing-iron, of a black heat, to the hoof, near to the crack. The intention, in doing this, is to warm and thus to soften the horn. This effect being accomplished, pare down or scoop off the edges—using the heated iron again, if necessary. Do all this leisurely, and with every consideration for the animal, which endures intense agony; for anything like violence or impatience tells fearfully upon the sufferer's system.

The horn being lowered, take a very sharp drawing-knife, and, with one movement of the wrist, excise the granulation. Set down the foot, and leave it to bleed; the loss of blood will lower the inflammation and will benefit the internal parts. Give a little green-meat to cool the system and act upon the bowels. Then, with the constant use of the lotion, enough has been done for one day.

The following morning you may again apply the lotion, and continue to use it afterward thrice daily. Any further lowering may also be accomplished to the edges of the crack, as well as the coronal portion of the horn be separated from the lower part of the hoof, by means of lines drawn as before illustrated.

If the horse must go to work, remember, it should not be in the shafts, upon long journeys, or with a heavy load behind it. Before the animal quits the stable, lay a piece of tow saturated with the lotion within the crack, and bind that in with a wax-end; tie a strip of cloth over all; give this bandage a coating of tar; and, when the horse returns, be sure to inspect the part. Should any grit have penetrated, wash it out with the lotion, and do not begrudge a minute or two to remove that which, if allowed to remain, may cause the animal much additional anguish. Then give the suffering creature a nice, deep bed, some scalded hay, and a mash made of bruised oats, into which has been thrown a handful each of linseed and of crushed beans; moisten these last constituents with the water drawn from the scalded hay, and, if the horse should not appear hungry, throw among the hay half a handful of common salt.

The poor man may have some excuse for working an animal with sandcrack; such a person cannot afford to keep the horse in idleness for the months which the cure will occupy. But the worst cases of this kind the author ever beheld have always been in quadrupeds belonging to wealthy tradesmen, who had ample means to gratify their desires, but wanted the heart to feel for mute affliction.

FALSE QUARTER.

False quarter is the partial absence of the outer and harder portion of the hoof; the consequence is, that the sensitive laminæ, in the seat of the false quarter, are only protected by their own soft or spongy horn. This is frequently insufficient to save the foot from severe accident; it is apt to crack, being strained by the motion of the hoof. The fleshy parts are then exposed; bleeding ensues, and fungoid granulations sometimes spring up; these are often pinched by the two sides of the divided horn, between which they protrude. When such occurs, the treatment should be the same as that recommended for sandcrack.

No art can cure a false quarter; a portion of the coronary substance has been lost, and no medicine can restore it. All that can be done is to mitigate the suffering; a bar shoe with a clip at the toe may be used, the bearing being taken off at the seat of false quarter. The portion of crust near to the weakened part should be beveled off, so as to join the soft horn with an insensible edge. Some persons recommend a mixture of pitch, tar, and rosin to be poured over the exposed quarter; the author has not found this compound to answer; it peels and breaks off upon the horse being put in motion. A piece of gutta-percha, of proportionate thickness, fastened over the place, has sometimes remained on for a week, and answered to admiration.

SEEDY TOE.

It appears not to have occurred to writers upon veterinary subjects that the horse, which breathes but to work—for the instant its ability to toil ceases the knacker becomes its possessor—that an animal which exists under so severe a law, should occasionally be "used up;" that a creature which is sold from master to master, all of whom become purchasers with a view only to "the work" each can get out of the "thews and muscles," should occasionally be debilitated to that stage which might interfere with the healthiness of its secretions, is a notion that seems to have been beyond the reach of those writers who have hitherto composed books upon the equine race. A separation between the union of the two layers of horn which compose the crust has been long known; it has been much thought about, and the fancy has been somewhat racked to account for its origin. Still, although the human physician has recorded the brittle state and abnormal condition of man's nails in peculiar stages of disease, no one seems thence to have argued that a certain condition of body might possibly affect the hoofs of our stabled servant.

The method of cure which the author adopted, led thereto by the admirable lectures of Mr. Spooner, and the success it met, soon made apparent the fact of its origin; but, before describing this, it may be as well to inform the reader in what consists a seedy state of the horse's toe.

The wall of the foot is composed of two layers—the outer one, the hardest, the darkest, and the thinnest, is secreted by the coronet; the inner layer, the softest, thickest, and most light in color, is derived from the sensitive laminæ. These different kinds of horn, in a healthy state, unite one with the other, so that the two apparently form one substance. The junction makes a thick, elastic, and strong body, whereto an iron shoe can be safely nailed, and whereon the enormous bulk of the horse's frame may with safety rest.

But when overwork affects the natural functions of the body, the two kinds of horn do not unite; their division invariably begins at the toe, as it always commences in the nail of the human being at the outer margin. If the seedy toe be tapped or gently struck, it emits a hollow sound; and if the shoe be removed, there will be found a vacant space between the two layers of horn; into this space a nail, a piece of broom, or a straw is commonly pushed, to ascertain the depth of the lesion.

Mr. Spooner advised that the whole of the detached horn should be cut away. The writer, however, insists that the horse should be thrown up—not turned out to grass, but placed in an airy, loose box, and liberally fed, or otherwise so treated as its condition may require. Once every fortnight, for two months, the smith should inspect the foot, and should cut away so much of the outer wall as may still be disunited. It commonly takes three or four months for the hoof to grow down or to become perfect; and rest, with liberal feeding, during this time, is sufficient to renovate an exhausted frame. A new and sound covering for the hoof of the invigorated horse is secreted by the expiration of the period named; nor has it reached the knowledge of the writer that any animal, after such a mode of treatment, has been liable to a second attack.

The ordinary method of cure is to cut away the hoof; then, having nailed a shoe on, to send the disfigured horse to resume labor. Under this form of treatment, the seedy division, once confined to the toe, has extended to the quarters; the structure of the hoof being destroyed, the horn was unfitted for its purposes. The weight of the body forced the sensitive laminæ from the coronary secretion, and the foot, after long treatment, became a deformity. The author has never beheld so lamentable a termination; but it is described by writers upon seedy toe with a complacency which seems to regard so grievous a result as the natural consequence of an intractable disorder.

TREAD AND OVERREACH.

Tread is a very rare occurrence with light horses; the author has met with but one instance. Then, from the horse being a good stepper, and from the accident happening toward the end of a long journey, as well as from certain indications of the wound itself, it was conjectured to have occurred in the manner depicted below.

However, among cart-horses such a form of injury is more frequent; these poor animals have to drag heavy loads, at a slow pace, it is true, but to long distances; they are generally badly fed. Farmers' horses, especially during the spring and summer months, being supported upon green-meat, the watery nourishment impoverishes the blood, and the exhausting labor undermines the system. Often the load has to be taken down hill, toward the end of a tedious journey; the whole burden then rests upon the shafts, and the wretched horse which is between them rocks under the weight like a drunken man. The legs cross, till at last the calkin belonging to the shoe of one hind foot tears away a large lump of the opposite coronet. A piece of flesh is commonly left upon the ground; the hemorrhage is extreme, and the wagon is brought to a stand.

The worst case of the kind the writer ever saw occurred after the preceding fashion; and the carter—who, by-the-by, was proprietor of the sufferer—left the poor horse in a forge, giving orders that the smith was to do what he could, or to have it killed, as he pleased. The smith consulted the writer, and he treated the wound after the method recommended for open joint, or by bathing it thrice daily with the solution of chloride of zinc, one grain to the ounce of water. In a week a large slough took place; this opened the coffin-joint, and left a portion of the extensor pedis tendon hanging from the orifice. The treatment was continued; the lameness, which at first was excessive, gradually grew less; the piece of tendon sloughed out, and the wound began to heal. It had closed when the animal was fetched away by the owner; but the writer was unable afterward to learn whether false quarter ensued upon the injury. This, from the extent of the wound, the writer would conjecture to have been probable; indeed, false quarter and quittor are the general consequences of severe tread.

Overreach is confined to fast horses; it happens to those which are good steppers. When tired, the feet are apt to be moved irregularly; thus, one foot is often in its place before the other has been lifted; the result is, that the inner part of the hind foot strikes the outer side of the fore coronet. A wound, and frequently a severe one, is the consequence. False quarter or quittor is likely to ensue; the treatment must be the same as was before described. No poultices are required; these only add to the weight of the injured limb, and augment the distress of the animal. No harsh measures should be allowed; the horse has enough to bear; a slough has to take place. This is a severe tax upon the strength; all the good food and prepared water the animal can consume will not now be thrown away; the treatment is materially shortened by the nourishment being sustaining of its kind, and liberal in quantity; but the injury should be treated only with the knife, and the chloride of zinc lotion described in the course of this article.

CORNS.

Corns are of four kinds—the old, the new, the sappy, and the suppurating; all are caused by bruises to the sensitive sole. The shoe is the passive agent in their production, when they occur in large, fleshy feet; the thick, unyielding, horny sole is the passive agent, when they are present in contracted feet. The coffin-bone, in both cases, is the active agent; the wings, or posterior portions of this bone, project backward nearly as far as the bars, or immediately over the seat of corn. When the horse is in motion, the coffin-bone can never remain still; it rises, or rather the wings are drawn upward by the flexor tendon, every time the foot is lifted from the earth, and sinks, because of the weight cast upon it, every time the foot touches the ground. The wings of the bone, thus in constant action, when the horny sole is weak, often descend upon the fleshy sole, and bruise that substance upon the iron shoe; what is called a corn is the consequence. In contracted feet, where the sole is high, thick, and resistant, the horny sole does not descend, even when the immense weight of the horse's body rests upon it. It remains firm and fixed during every action of the animal—not so, however, the coffin-bone, which is in continuous motion. The result, of course, is, the imposed burden forces the wings of the coffin-bone downward. The horny sole will not yield, and the fleshy sole is therefore bruised between the wings of the coffin-bone and the horn bottom of the hoof; a corn is thereby established.

Corns in a horse do not answer to those excrescences found upon the feet of man; being bruises, they consist of effusion in every instance. The effusion may either be of blood or of serum; blood constitutes the old and the new corn, serum gives rise to the sappy corn. The suppurative corn is an after-consequence of either of those just named; when the effusion has been so large as to defy absorption, a new action is started up—pus is secreted, and a suppurative corn is then created.

An old corn is the least serious, especially when it is easily cut away; it appears as a black mark upon the surface of the horny sole, and is little thought of when it can be speedily removed by the knife, because this shows the horse had a corn, but at present is free from such an annoyance. When, however, a superficial corn cannot be scooped out with the drawing-knife, but becomes brighter and brighter as more and more horn is cut away, till it assumes the scarlet aspect of a new corn, the matter is rather grave, because it denotes the horse to have had, and not to have been free from, corns during the growth of the present sole.

The new corn, as has been just intimated, consists of a portion of blood effused into the pores of the horn, and is of a bright-scarlet color. The size is of some consequence, as it best intimates the extent of the injury; if the stain be small and deep seated, it is of least moment.

The sappy corn is the consequence of a more gentle bruise, when serum and lymph only are effused—the horn being thereby merely rendered moist, not discolored. This species of corn is not very common, and by proper shoeing is readily removed.

The suppurating corn is the worst of all; it engenders heat in the foot, and causes excessive lameness; it creates all that anguish, a shadowy taste of which the human being endures when pus is confined beneath the substance of the finger-nail. The foot cannot be put to the ground; the arteries of the pastern throb forcibly; the countenance is dejected; and every symptom of acute suffering in a large body is exhibited.

Corns, which in man are found on the lower members, in the horse are generally witnessed only upon the fore feet. The writer has rarely seen an instance of their presence behind; but in whichever foot they appear, they must be the production of an instant, though, probably, the suppurative may be an exception; yet from these always being suddenly observed, even this species are said to be of instantaneous origin. A horse, when progressing, makes a false step; a sanguineous or sappy corn is by that faulty action established. The same horse may trot home perfectly sound, and be put into the stable for the night a healthy animal; but on the following morning it may be discovered standing on three legs. Pus may, in the interval, have been secreted, and the corn may have assumed the suppurative character.

The manner to examine for corn is, in the first place, to mark the age of the horse; then observe if, in the trot, either leg is favored. The animal being young, splint is the common cause of uneven action; if old, corns are more generally expected; the horse is brought to a stand and the smith sent for. The man raises the fore foot, and, taking a portion of crust and sole between the teeth of the pincers, gradually increases the pressure; he thus proceeds till he has by successive trials squeezed the sole all round. If the leg, while undergoing the operation, be withdrawn near either of the nails, the ideas take a different direction to that of corn; but if the foot be held steady, the seat of corn is lastly squeezed. Should no flinching be witnessed, the examination is not esteemed satisfactory until the smith has, with a small drawing-knife, denominated a searcher, cut away a portion of the sole at the seat of corn.

The sensibility will be extreme should suppurating corn be present; in that case the sole must be gradually removed until the pus is released. That being done, the shoe should be taken off and the foot put into a bran poultice. By this means the horn will be rendered more soft and the wound cleansed. The smith, on the following day, must again cut the foot, every portion of detached horn being very carefully excised.

The horn is itself a secretion, and, in a healthy state, is intimately united with the source of its origin. When, however, pus is effused, this always lies between the secreting membrane and the horn, which has been already secreted. The horn so displaced by the presence of a foreign substance is called under-run or detached; and all horn, so under-run or detached, must be removed. When this operation is properly performed, all signs of lameness will have generally disappeared. It is usual, however, to tack the old shoe on again; and having dressed the injury with chloride of zinc and water—one grain to the ounce—there remains only to examine the foot from time to time till new horn covers the surface; merely taking precaution for the present to shield the wound with a little tow, fastened in its place by a couple of cross splints.

When sanguineous or sappy corns are found, the method is, firstly to thin the sole, so as to render it pliable, especially over the seat of corn. Should a sappy corn have rendered the horn moist for any space, or should the discoloration caused by sanguineous corn be of any size, it is as well always to open the center of the part indicated: no matter should the cut release only a small quantity of serum or a little blood. Take away a small portion of horn; pare the sole till it yield to the pressure of the thumb. When such a proceeding is necessary, the bars may be entirely removed, and the wounds should be covered with some tar spread upon a pledget of fine tow. As soon as the orifice is protected by new horn, the horse may be shod with a leathern sole and returned to its proprietor.

Such a course would occupy little time—a week at most. Yet the great majority of horse proprietors appear to have "flinty hearts," as nearly all of them begrudge the necessary day of rest to the maimed animal which has been injured in their employment. The cry, where the horse is concerned, is "toil, toil!" The veterinary surgeon is often asked "if absolute rest is imperative." He is frequently solicited to patch up the poor animal, so that it may do a little work. As day after day passes onward, the tone becomes more and more authoritative. The horse is at last too often demanded from the hospital, and taken to resume ordinary labor before the injury is effaced. Should no evil effect ensue on such a culpable want of caution, the proprietor is apt to chuckle over his daring with another's sufferings, and to blame the science which would not incur risk, even to propitiate an employer.

Corn is not generally reckoned unsoundness. If a horse be lame from corn, the lameness renders the horse unsound; but the corn does not. Such is the beauty of horse logic when pronounced in a court of justice! A corn may suppurate, or may provoke lameness at any moment. Still the corn, in the bleared eye of the law, is no sufficient objection to the purchase of a horse. The suppurated corn may lead to quittor—still, corn is not legal unsoundness. It is a pity such is the case, since it leads men to neglect that which is removable. When the sole is high, the shoe should always be accompanied by a leathern sole. Liquid stopping should be poured into the open space at the back of the foot; and at every time of shoeing, the smith should pare the sole quite thin, even until drops of blood bedew the surface of the horn. When corns appear in flat or fleshy feet, as shoeing time comes round, only have the very ragged portions of the frog taken away. Have the web of the shoe narrowed so as to remove all chance of pressure against the iron. Lower the heels of the shoe, or try a bar shoe with the bearing taken off over the seat of corn; should that not answer, next put on a three-quarter shoe: many horses, however, will go sound in tips, that cannot endure any other sort of protection to the foot. By resort to one or the other of these measures, that injury, which in the learned eye of the law is of no consequence, but which, nevertheless, may lead to terrible lameness, or even lay the foundation for a quittor, may be greatly mitigated.

Bruise of the sole is an accident leading to effusion of blood—so far it resembles corn; but it is dissimilar in not occurring on a part subject to the same degree of motion, and, therefore, is not so severe in the consequences to which it leads. It is caused by treading on a stone, and is removed by paring off the horn which has been discolored or lies immediately beneath the injury. It seldom leads to great lameness or gives rise to serious results. It is treated after the manner directed for corn; but it is always advisable to shoe once, with leather, the horse which has suffered from bruise of the sole. The difference between corn and bruise of the sole is simply this: the first is an injury produced by a cause which is always within the control of the proprietor, and which, if neglected, is likely to lead to the most disastrous maladies; the last is purely an accident, to which any horse at any time is liable, and with ordinary care is not likely to give rise to any serious consequences.

Prick of the foot is an injury incurred while the horse is being shod. There are two sorts of this accident: one, when the nail penetrates the fleshy substance of the sensitive laminæ and draws blood; the other is when a nail is driven too fine, or among the soft horn which lines the interior of the hoof, and consequently lies near to the sensitive laminæ. The first is of the more immediate importance; but the last may be equally serious in its effect. As the horse works, the strain upon the shoe bends the nail fixed into soft horn. It thus is made to press upon the sensitive laminæ, and may provoke suppuration.

To detect whether the smith is at fault, the foot should be first squeezed between the pincers as for common corn; then have the nails withdrawn one by one, and mark each as it is removed. If one appears moist or wet, have the hole of that nail freely opened. Let the shoe be replaced, leaving that nail out. Put a little tow, covered with tar, over the wound, and shoe with leather. If, however, lameness should still be present, the shoe must again be taken off and the injury treated as recommended for suppurating corn.

Blame the smith who pricks a horse and conceals the fact; punish the fellow to the extent of your power. But the man who pricks a foot and acquaints you with the circumstance, deserves civility. The last enables you to take proper measures, such as paring out, etc., and thereby you avoid all unpleasantness. The first braves chances with your living property, and deserves to suffer if the hazard go against him.

QUITTOR.

This is a severe and painful disease. Many a horse is, at the present moment, working with a suppurative wound above the hoof, within the interior of which run numerous sinuses. The police arrest the driver of the horse when the condition is so bad as permits the collar to wring the shoulders. Of all other shapes of misery they seem ignorant. Animals limp over the stones, every step being an agony; but the policemen look on at such pictures with placid countenances. Horses are driven at night in a state of glanders which renders them dangerous to mankind; yet no officer thinks of looking at the head of an animal for the sign of suffering or the warning of public peril. Creatures, in every stage of misery, may be seen openly progressing along the streets of the metropolis; but so the shoulders be sound, the brute who goads them forward performs his office with impunity. Still, it is something gained, that the law has recognized the want of man's absolute power over the feelings of those creatures intrusted to his care. Let us hope, as knowledge extends, the legal perceptions will be quickened. It is partly with this view that the present "illustrated work" is published.

Quittor is a terrible disorder. To comprehend thoroughly the pain which accompanies it, the reader must understand the structures through which it has to penetrate, and the substances it has to absorb. All parts are slowly acted upon in proportion as they are lowly organized. Cartilage is the structure into the composition of which no blood-vessels enter. Next to cartilage is bone, which, though supplied with vessels, is, on account of its mixture with inorganic matter, exposed only to slow decay, and the exfoliation of which is effected at a vast expense to the vital energy. These substances mainly compose the foot of the horse. In addition, there is ligament, almost as slowly acted upon as bone; disease in which substance is accompanied by the greatest anguish. Horn is an external protection; but that material, though an animal secretion, is strictly inorganic: when cut it does not occasion pain—neither does it bleed. If a portion of horn should press upon the flesh it must be removed by the knife; for, unlike the more highly-gifted structures, there is no chance of its being absorbed.

The hoof, therefore, being the external covering to the foot of the horse, and not being liable to the same action as organic secretions, serves to confine pus or matter when generated within its substance. Pus could work through the largest organized body; but it cannot escape through the thinnest layer of horn. Now, most of the other substances which enter into the composition of the horse's foot are such as slowly decay; but those parts which slowly decay being without sensation during health, occasion the most extreme agony when diseased.

The cause of quittor always is confined pus or matter, which, in its effort to escape, absorbs and forms sinuses in various directions within the sensitive substances of the hoof. In the hind feet of cart-horses quittor generally commences at the coronet; the coronet is wounded or bruised by the large calkins or pieces of iron turned up at the back of the hind shoes, which are universally worn by animals of heavy draught. Any one who has punctured or cut the coronet of a dead horse knows this structure is as difficult to penetrate and as hard to divide as cartilage itself; the consequence of an injury to such a part is, the bruise produces death of some deep-seated portion of the compact coronet. Nature, after her own fashion, proceeds to cast off that which is without vitality, or, in other words, she divides the dead from the living tissues by a line of suppuration; but the matter thus located cannot readily escape through the harsh material of the horse's coronet. It is confined and becomes corrupt, while the constant motion of the foot and the higher organization of the secreting membrane of the horn inclines the pus to take a downward direction. However, it is more difficult for pus to pierce the horny sole than to penetrate the coronet; so the effort is renewed above; numerous pipes or sinuses are thus formed upon the sensitive laminæ; the fleshy sole is often under-run, and this mischief goes on until the coronet, which becomes of enormous size, at last yields to the increasing evil.

Another cause is pricking the sensitive part of the foot with a nail during shoeing; the wound generates pus, the pus cannot penetrate the horn, and the motion of the coffin-bone causes it to absorb upward, until after some time it breaks forth at the coronet.

Another cause is corn; the horse's corn is nothing more than a bruise; the bruise, in some instances, is severe, and takes on the suppurative action. The pus, as before, is confined, and by the motion of the coffin-bone it is propelled upward till it breaks forth at the coronet, which, as before, enlarges to deformity; in short, any injury done to the sole of the foot or to the coronet above it may produce quittor.

The leading sign of quittor, before it breaks, is a large swelling at the coronet, attended with heat and excessive lameness. In cart-horses, it is usually present in the hind feet; but in the lighter species it more frequently occurs in the fore feet. It generally appears upon the inner side of the hoof, though, of course, it has often been witnessed upon the outer coronet. Quittor becomes a huge swelling before it breaks. The amount of tumefaction symbolizes the amount of anguish; it is, indeed, a most painful disorder.

The animal, after the pus has found vent, becomes easier; fever departs; the appetite returns, and the enlargement greatly diminishes.

In the cure of a quittor, all depend upon the time during which the disease has been allowed to exist; if brought under notice at first, and from an examination a belief is confirmed that the sinuses are wholly superficial, no treatment is comparable to the plan of slitting them up, the method of doing which will be described in a subsequent chapter; this at once affords relief. The horse, which was limping lame, upon getting up puts the foot fearlessly to the ground, and trots sound.

If we have reason to believe the matter has burrowed inwardly, and that one or more sinuses have penetrated the cartilages and threaten the deeper-seated parts, still we should settle with the knife all those pipes which are superficial. This gives a better view of the structures supposed to be diseased; then, if among the matter thrown out by the healing wounds there is seen a speck or two of fluid, which, being gelatinous and transparent, looks dark among the opaque creamy pus, be sure there remains further work to be accomplished.
