The publishers of the present work have long been im- pressed with the idea that a new book upon the Diseases of the Horse, written in simple language, and specially de- signed as a guide for non-professional readers, had grown to be a public necessity. While waiting for an opportunity to carry this notion into effect, they were fortunate enough to become acquainted with a gentleman whose proficiency in veterinary science is undisputed. To that individual the present work was intrusted ; and it was nearly com- pleted when the publishers heard with surprise that Mr. Mayhew employed the pencil in a manner only secondary to his use of the j)en. Acting on this information, the publishers were induced to persuade the author to illustrate his text by drawings descriptive of the various stages and aspects of disease. The addition of above four hundred wood engravings has, of course, materially increased the expense of publication. A heavy outlay has been incurred, while, at the same time, the spirit of the age is decidedly against paying a large sum for any work of general information. These circum- stances render the present volume doubly hazardous. How- ever, it is confidently hoped that, when the accuracy of the illustrations and the perspicuity of the letter-press are appreciated, a large sale will more than recompense any amount of outlay. a) PREFACE. When laying the present volume before the public, the author cannot but feel he addresses two very opposite parties : one, and by far the larger portion of society, views the subject of which this book pretends to treat simply as a working machine, and regards all those who speak of the creature as endowed with intelligence or pos- sessed of sensibility as fanciful sentimentalists checked by no limit to assertion. The other class — a small, but a highly-educated and an influential section of the public — sees the matter in a very contrary light. In their ideas, the equine race, though endowed with voice, is not entirely without reason, but possessed of the keenest feelings and capable of the tenderest emotions. The last party, however, expect so little from living writers that probably they will be pleased with opinions which they may hail as an advance toward the truth. The first order of readers, however, tie author cannot think to propitiate. Before the opening article is perused, one of these gentlemen will probably fling the volume aside with a sneer, and exclaim — " Why, what would this fellow have ? Does he desire we should build hospitals for horses ?" To the uninformed mind such a question will suggest a preposter- ous image. But, when calmly considered, a hospital is perceived to be uothing more than a place where disease in the aggregate is cheaply treated, and the trouble or the expense of individual reme- dies thereby is prevented. A hospital for horses, sanctioned by gov- ernment, and honored with the highest patronage, does even now exist in the Royal Veterinary College of Camden Town. Such a (9) 10 PREFACE. foundation, therefore, would prove no positive novelty; but were such institutions more general, a necesssity now universally felt would be supplied, while the duty incumbent on mankind to conserve the lives of beings intrusted to their care would, in such structures, be grace- fully acknowledged and openly enforced. No man possessing a horse is willing the animal should perish. His interest cleai'ly is in the prolongation of its life ; and he would gladly part with some money rather than be reduced to the owner- ship of a carcass. That, however, which he wishes to have accom- plished he desires should be performed cheaply. Hospitals — supposing such places existed, and were of different grades or of different scales of charges — would afford the best prospect of relief at the smallest remunerative cost. Still, any application to such establishments must of necessity prove a tax, the only known preventive against the visi- tation of which would be the exercise of a little humanity. A very slight expenditure of the last-named quality would save the equine race from a long list of ills which now are consequent upon mortal ignorance or upon human brutality. It is painful to reflect how many of those affections spoken of as equine disorders might be cheaply eradicated by the more reasonable treatment of thf animal which man proverbially esteems to be his most hazardous property. Cruelty is a very extravagant indulgence. There are now living persons who merely treat their horses according to the dictates of reason, and whose stables are graced by working lives of an extreme age. When he last walked through the Royal Mews, the author was much gratified to behold several fine animals, in the full enjoyment of strength and of vigor, which had more than attained their twen- tieth year. It might prove nationally remunerative if all of her Britannic Majesty's subjects would permit the creatures over which they exercise legal ownership to live and to labor for their natural terms of exist- ence. However, during the glorious days of post chaises, the horses for these vehicles generally cost £30, while, as an average, they ex- isted upon the road only two years. What a sacrifice of life and of money I Each horse cost the post- PREFACE. 11 master £15 yearly ; while the animals working for the queen, and drawing carriages not conspicuous for lightness, if bought originally for a like sum, would not cost more than £1 per annum. The con- trast is certainly startling. But to perfect it, there remain to picture the sorry jade which was formerly harnessed to the public chaise, and the stately creature which, in all the delight of beauty, accom- panies Royalty to the Parliament House. But there are other items to be considered before the opposite accounts can be fairly placed one against the other. A post-house generally was a pest-house. The miserable inhabitants of such a build- ing did not suddenly die off, but, like other things, horses rocked to and fro before they fell. The closing scene of life was heralded by many fits of sickness, each of which was of varying duration. Were we to reckon the money which loss of services abstracted, the extra cost of those attentions which are imperative when health is failing, and the hard cash paid for veterinary assistance, very probably a far wider distance than at first glance is apparent would divide the Royal Mews from the sheds which used to form a part of every large roadside hotel. In the writer's conviction, humanity toward animals should be more commonly practiced — if not from any higher motive, because it is certainly the truest economy. To make this fact plain is the in- tention of the present publication. To prove that horses are gifted with something beyond the mere sensation which is common to all moving things is the object of the present work. To convince the public, by appealing to the eye and to the understanding through the means of engravings and of letter-press, that the equine race inherit higher feelings than the vast majority of mankind are prepared to admit, is the purpose of the book now in the hands of the reader. To demonstrate how closely nature has associated man and horse in their liabilities and in their diseases — to induce men, by informing their sympathies, to treat more tenderly the timid life which is dis- posed to serve and is also willing to love them — is the highest reward the author of the following pages can picture to himself. When making the foregoing acknowledgments, the author does not affect to disdain that recompense which is the due of every person 12 PREFACE. who labors in any arduous pursuit. This, of course, he accepts. Though it did not enter into his thoughts when contemplating the composition of the present book, it nevertheless may have stimulated his exertions to perfect it. But, in addition to any weight that can be attached to such a motive, he desired to compose a work which should render the gentleman who had consulted it independent of his groom's dictation ; which should enable any person who had read it capable of talking to a veterinary surgeon without displaying either total ignorance or pitiable prejudice; which, in cases of emergency, might direct the uninitiated in the primary measures necessary to arrest the progress of disease ; and which, when professional assist- ance could not be obtained, might even instruct the novice how to treat equine disorders in such a manner as would afford a reasonable prospect of success. When the regular diet and simple lives of most horses are regarded, the latter expectations certainly do not seem beyond the reach of human ambition. Cleanly and simple remedies alone are required ; and these gentlemen of the highest rank may, without fear of taint or of ridicule, condescend to prescribe. To secure such an end, the present book has been written in plain language. The author has endeavored to eschew hieroglyphics and to avoid technicalities. The meaning has shaped the terms employed, and all the graces of style have been intentionally discarded. In conclusion, the author has to thank the publishers for the very handsome shape in which they have been pleased to embody his efforts ; likewise he has to acknowledge an obligation to the skill and the ability with which the Messrs. Dalziel have seconded his endeavors. CONTENTS. CHAPTER I. The Brain and Nervous System— Their Accidents and their Diseases.

THE BRAIN AND NERVOUS SYSTEM — THEIR ACCIDENTS AND THEIR DISEASES. PHRENITIS. Phrenitis implies inflammation of the brain. Madness and extreme violence are the consequences. The animal, in this condition, disregards all recognitions, and, apparently, loses all timidity. It suffers the A HORSE MAD, OE WITH INFLAMMATION OF THE BRAIN. greatest agony, and no terror can appal it. It would rejoice, could it anticipate the effects, if the mouth of a loaded cannon were pointed 2 (It) Ig P H 11 E N I T 1 S. toward itself, and would look for relief when the portfire descended upon the touch-hole. Every movement seems designed to end its own existence ; but the furor has no malice in it. The creature strives only to injure himself. It may in its efforts shatter and demolish the struc- tures which surround it; but it does so without intention. That is merely the result of its being carried away beyond the things of this world by a mighty anguish. It desires harm to no one ; but it cannot remain quiescent, and endure the torment which rages within its skull. When this stage of the malady appears, the best thing is to antici- pate the evident wish of the animal. The teaching of schools, which instructs young men to meddle with the strength of an infuriated horse, is mere prattle. However, if the disease, as it seldom happens, is per- ceived approaching, something may be attempted. Before the violence commences, the horse is generally dull. It does not obey the rein or answer to the lash. It is heavy beyond man's control. It snores as it breathes. The lids drop ; the head sinks ; the body is cold ; the mem- brane of the nose is leaden in color; and, from being the obedient, watchful, and willing slave, its entire nature appears to have changed. It does not attend to the goad, and the voice of the driver may bawl in the harshest key, but the sound which used to excite seems unheard and is unheeded. The remedy for the earlier stage is copious blood-letting. Open both jugulars and allow the current to flow till the countenance bright- ens or the animal sinks. Bleed again and again, if necessary. Give purgatives of double strength, and repeat them every three hours, till the bowels are copiously relieved or the pulse changes, or the general appearance indicates improvement. Afterward, administer sedatives, always as infusions. A scruple of tobacco, half a drachm of aconite root, or a drachm of digitalis should have a pint of hot water poured upon it. When the liquid is nearly cold, it should be strained, and the dose may be repeated every half hour, until its operation is witnessed in the more quiet behavior of the animal. In the generality of cases, however, no opportunity for such treat- ment is presented. The disease is most common in the agricultural dis- tricts, and is usually seen where carters indulge their passion in the butt-end of the whip employed upon the horse's head. The cause is, however, carefully concealed, and, after the violent stage has set in, the original wound is generally mistaken for some self-inflicted injury. Thus, the horse, even in the most horrid of deaths, with a generosity characteristic of its nature, contrives to shield the being whom it served and loved, from the consequences of his inhumanity. Should the animal, by such means, recover, treat it gently ; do not ABSCESS WITHIN THE BRAIN. 19 excite it; for phrenitis is apt to return. Even recovery is not always to be wished for. The depletion, imperative for the cure, too often engenders the weakness which no care can eradicate ; and the animal survives only to change from the willing servant into a troublesome valetudinarian. ABSCESS WITHIN THE BRAIN. This sad affection is invariably produced by external injury. A horse runs away and comes in contact with some hard substance. The blow is of sufficient violence to fracture the strong cranium of the quadruped and to smash all that remains harnessed to the animal. Here we have a reason why man should establish more than a brutal mastery over the A HORSE DYIMO FROM ABSCESS WITHIN THE BRAIN. animal he possesses. The horse is the most timid of creatures. It, however, quickly learns to recognize the voice of its owner. In its vast affection, it soon trusts with confidence to the person who is kind to it. An occasional word thrown to a patient and willing servant, spoken softly to the animal which is putting forth all its strength for our pleas- ure, would not be cast away. When dread overpowers the horse and it begins to run at its topmost speed, do not pull the reins : the first check should be given by the voice. Speak cheerfully to a timid creature. If the first word produces no effect, repeat it. Watch the ears. If these are turned backward to catch the accents, talk encouragingly to the horse. The voice of one it loves will restore its confidence. The pace will slacken. Talk on, but always in a tone calculated to soothe dis- tress. Then gently touch the reins. The first gentle movement may not be responded to, but the second or the third will be ; and the animal, released from terror, is once more under your control. This is much better than tugging and flogging, which obviously are thrown away upon a body that horror has deprived of sensation. The 20 STAGGERS. noise and the resistance but feed the wildness of the fear, and, in the end, the driver is carried to a hospital, the horse being laid prostrate among the ruins it has made. When led back to the stable, a wound is discovered on the animal's forehead. It is so small it is deemed of no consequence. A little water oozes from it — that is all — it does not send forth matter, or it might deserve attention. However, in a short time the horse becomes dull. It will not eat. Soon it falls down and commences dashing its head upon the pavement. There it lies, and, day and night, continues its dreadful occupation. One side of the face is terribly excoriated, and must be acutely painful ; but the horrid labor still goes on, each stroke shaking the solid earth, which it indents. At last death ends the misery, and a small abscess, containing about half a drachm of healthy pus, is discovered in the superficial substance of the brain. Physic or operation is of no use here. The cranium of the horse is covered by the thick temporalis muscles. This alone would prevent the trephine being resorted to. Blood would follow the removal of any portion of the skull. Besides, what or who is to keep the head still during the operation? and, were the operation possible, who would own an animal with a hole in its skull ? The only means of cure would be to afford exit to the matter ; and to do that is beyond human in- genuity. STAGGERS— SLEEPY STAGGERS AND MAD STAGGERS. Staggers means no more than a staggering or unsteady gait; an incapacity in the limbs to support the body. It therefore, by itself, represents only that want of control over voluntary motion which generally accompanies injuries to the brain. Mad and sleepy staggers represent only different symptoms or stages of cerebral affection. Sleepy staggers implies the dull stage, which indicates that the brain is oppressed. Mad staggers denotes the furious stage, when the brain has become acutely inflamed. There is but one origin known for staggers, and that is over-feeding. Carters take the team out and forget the nose-bags. The omission is not discovered till far on the road. No thought is entertained of turn- ing back. The poor drudges, consequently, have to journey far, to pull hard and long upon empty stomachs. When home is at length reached, the driver thinks to make amends for neglect ; the rack and manger are loaded. Such animals as are not too tired to feed, eat ravenously. The stomach is soon ci*ammed ; but fatigue has weakened the natural instincts, and domestication has taught the horse to depend entirely on man. The creature continues to feed, STAGGERS. 21 till a distended stomach produces an oppressed brain. An uneasy sleep interrupts the gormandizing. The eye closes and the head droops. Suddenly the horse awakens with a start. It looks around, becomes assured and takes another mouthful. However, before mastication can be completed, sleep intervenes, and the morsel falls from the mouth or continues retained between the jaws. This state may continue for days. The horse may perish without recovering its sensibility; or mad staggers may at any period succeed, and the animal exhibit the extreme of violence. Mad staggers equally results from carelessness in the horsekeeper. The animal which gives itself up entirely to the custody of man, too often experiences a fearful return in recompense for its trustfulness. Any neglect with regard to the feeding of a horse, may entail the worst ; and a most cruel death upon the inhabitant of the stable is too often its reward. The groom, perhaps, may slight his work, lock the stable door and hurry to his beer-shop, leaving the lid of the corn-bin unclosed. The horse in his stall, with his exquisite sense of smell, scents the provender and becomes restless. His desire is to escape from the halter. With fatal ingenuity the object is accomplished, and the next moment the animal stands with its nose among the coveted oats. It eats and eats as only that being can whose highest pleasures are limited to animal enjoyments. After a time it becomes lethargic ; but from that state it is soon aroused by a burning thirst. The corn has absorbed all the moisture of the stomach, the viscus being dry and dis- tended. Pain must be felt, but thirst is the predominant feeling. Water is sought for. None is to be found ; and the sufferer takes his station near the door, to await the appearance of his attendant. No sooner is the entrance opened, than the quadruped dashes out. With all speed it makes for the nearest pond. There it drinks the long and the sweet draught few in this life can taste ; but to know which, is to die a terrible death. The corn swells more with the liquid imbibed. The stomach is now stretched to the uttermost. Continued tension causes inflammation. The brain sympathizes, and the horse speedily becomes acutely phrenitic. There is, however, a strange symptom, in which the two disorders appear mingled. The sleepy fit is not entirely removed, nor are the violent symptoms fully developed. The horse, in this condition, will press its head against a wall. In doing this, it only displays an impulse common to most animals in the sleepy stage ; but the peculiarity is, that the eye may be half unclosed and the limbs vigorously employed, as though a trotting match were going forward. The breath will quicken and the creature be coated with perspiration. This attitude and motion 22 STAGGERS. may subside, and recovery may ensue; but commonly the quadruped drops, moves the limbs as it lies upon the ground, and is only quieted by death. In a few instances horses have left the wall to exhibit the utmost violence, and to sink at last. When corn has been gorged during the night, the animal must be rigidly kept from drinking. A quart of any oil should be immediately administered. A pint of oil is the ordinary dose; but here there exists more than an ordinary disease. Besides, much of the fluid will sink between the grains," and, probably, not half of it will reach the mem- brane of the stomach. Oil is preferable to the solution of aloes, which is generally given, inasmuch as it will not act upon or swell the corn so readily as any medicine dissolved in water. Should no amendment be detected, in six hours repeat the dose. In another six hours, give another dose with twenty drops of croton oil in it. When another period has elapsed, should no improvement be noted, give thirty drops of croion in another quart of oil. Should none of these drinks have taken effect, the round must once more be gone over. However, at the slightest mitigation of the symptoms or even suspicion of amendment, stop all medicine at once. The altered aspect of the horse is the earliest symptom that the distention is relieved. In sleepy staggers, the head hangs pendulous or is pressed firmly 8LEEPT 8TAG0ERS, FROM OVER-GORGING. against some prominence. The pulse throbs heavily — the breathing is laborious, and the animal snores at each inspiration. The eye is closed; the skin cold and the coat staring. The nasal membrane leaden. The ._ J STAGGERS. 23 mouth clammy ; the ears motionless ; the tail without movement, and the breathing alone testifies that it is a living animal we look upon. The signs that announce the advent of mad staggers, from whichever cause the disease may arise, are always alike. The lid is raised, and the eye assumes an unnatural brightness. The nasal membrane reddens; the surface becomes as hot as it was previously deficient in warmth; the movements are quick and jerking. The breath is no longer laborious — it is rapid, sharp, and drawn with a kind of panting action. The whole appearance is altered. The characteristics of approaching frenzy can hardly be mistaken. Then comes the most painful duty of ownership over life. The pro- prietor has, then, to make a speedy choice, whether his dumb servant is to take a desperate chance and undergo a torture for which the con- centrated pleasure of many lives could not atone, or be deprived of the fatal power to injure others and itself. Humanity would unhesitatingly pronounce for death, and, iu this case, there is need of haste. The symptoms are so rapidly matured, that, in ten minutes, the poor horse may be sadly hurt and bleeding, panting and rearing, in the center of a THE HORSE BURINO THE MAD STAGE OP 8TAG0ERS. desolated stable. A mad horse is a terrible object! Its strength is so vast that ordinary fastenings yield before it; but the animal, even when deprived of reason, wins our respect. Suffering will find expression in energetic action. Man, when a tooth is about to be extracted, generally 24 MEGRIMS. clinches something ; but what were a hundred teeth to the agony which causes every fiber in the huge framework to quiver ? The perspiration rolls off the creature's body. The eye glares with anguish, not with malice; the body is strangely contorted, but there is no desire to in- jure. Who, contemplating such a picture, could forbear speaking the word which should grant peace to the sufferer, although the order neces- sitate some violence to the feelings of him who is invested with power to command ? MEGRIMS. So little sympathy exists between man and horse, so little are the ailments of the animal really studied, that the likeness between certain diseases affecting the master and the servant have not been observed. Megrims, evidently, is a form of epilepsy ; yet, to speak of an epileptic horse would, probably, induce laughter in any society. Notwithstand- ing which, man is not isolated in this world : he is associated with the creatures of the earth not only by a common habitation, but by similar wants and like diseases. He is united by nature to every life that breathes. His heart should feel for, and his charity embrace, every animal which serves him. He has his duty toward, and is bound by obligations to, every creature placed under his control. None are so subject to his will as is the horse ; none have such powerful claims to his kindness and forbearance. The noble animal is begotten by man's permission ; its course in life depends upon his word : for his service it surrenders everything — freedom, companions, and paternity — it relin- quishes all. Its owner's pleasure becomes its delight; its master's pro- fit is its recreation. It is the perfect type of an abandoned slave ; body and soul, it devotes itself to captivity. It is sad to think how bitter is its recompense, when an obvious similarity, even in aflliction, has not to this hour been recognized. Megrims, like epilepsy in man, will in certain subjects appear only during some kind of exertion. In others, it will be present only during particular states of rest. It is uncertain in its attacks. It is not under- stood ; and of the many theories which have been advanced, none ex- plain it. All horses may show megrims; some when at work, and some only while in the stable ; others in the glare of day, and a few during the darkness of night ; but of all, draught horses are the most liable to the malady. This may be because harness horses are subjected to the most laborious and most continuous species of toil. A horse fettered to a vehicle obviously must strain to propel as much or as long as the person intrusted with the whip thinks the animal should draw. Men's con- MEGRIM S. 25 sciences, where their own convenience and another's exertions are the stake, generally possess an elastic property. It takes a great deal to stretch them to the utmost. An Arabian proverb says, "it is the last feather which breaks the camel's back;" but the English driver knows the entire pull is upon the collar, and he is moved by no considerations about the back. If the whip cannot flog the poor flesh onward, a shout and a heavy kick under the belly may excite the spasm, which, in its severity, shall put the load in motion. Age does not influence the liability to megrims. The colt, which has done no work, may exhibit the disease, and the old stager may not be subject to its attacks. One horse may die in the field from exertion and never display the malady ; another shall be led through the streets and exemplify megrims in all its severity. One shall be merely dull — the disorder shall never get to the acute stage, though the fits may be re- peated. This last, to the surprise of its master, shall every now and then stop, stare about, and proceed as though nothing were the matter. A second, when mounted, will be seized by a sudden impulse and run into shop doors; while a third, being between the shafts, will be pos- sessed with an irrepressible desire to inspect the driver's boots. The horse often becomes suddenly stubborn. The reins are jagged and the whip plied to no purpose. The animal will only go its own way, which is commonly beset with danger. Perhaps, it may persist upon galloping, head foremost, down an open sewer; probably, it will rush up the steps leading to some mansion, and beat the door in with tremendous knocking. Then come convulsions, followed by insensibility. If such a scene occur in a city, of course a crowd collects. Opinions are noisy and various; but a majority incline toward bleeding from the mouth. It is only to cut the palate, and a dozen knives, already opened, ai"e proffered for the purpose. However, let the person in charge attend to no street suggestion. Let him at once seat himself upon the horse's head, and re- main there till consciousness returns ; then speak kindly to the sufferer, loosen the har- ness, and take care that the animal is per- fectly recovered before it is permitted to rise. THE EXPRESSION CHARACTERISTIC OP Dealers pretend that a horse subject to repeated attacks of megrims. megrims is to be readily told. A horse, after repeated fits, is easily singled out ; but the animal which has experienced only a single attack, 26 MEGRIMS. no man could challenge. One attack, however severe may be its char- acter, will not necessarily leave its impress upon the countenance. But the creature subject to such visitations soon assumes a heavy, flaccid, and stupid expression. The disease distorts no feature, but it leaves its mark behind; and any man, acquainted with the subject, would have no difficulty in picking from a drove the horse which has endured re- peated fits of this disorder. Another class of knowing ones pretend they can drive a megrimed horse any distance, by simply keeping a wet cloth over the brain. This last experiment is, however, not inviting; ar)d the author has yet to be assured by science that a wet rag over the brain would repose upon the primary seat of the disease. When a horse has the first fit of megrims, at once throw the animal up. Do not strive to sell the diseased creature, as such a sale is illegal. The law presumes everything sold to be fit for its uses. Thus, a person buying rotten eggs can recover at law, because eggs are sold for human food, and no man can eat a tainted egg. So a megrimed horse is unfit for employment. Recovery in this disease is always doubtful. A chance is best secured by throwing the horse up on the first attack. Do not turn a sick animal out to grass. Keep in a loose box, covered with plenty of straw. Feed liberally, and with the best food. Have the body regularly dressed, and the animal led to, not ridden to, exercise. Allow a quart of stout every morning and half a pint of oil every night. Above all things, attend to the stabling. Let the box be large and well ventilated. Food is eaten but occasionally during the day. Air is as essential as more substantial nutriment to life, and is consumed night and day. Food has to undergo a complicated change, and to travel far, before it joins the blood. Air is no sooner inhaled than it is imme- diately absorbed by the blood. After such a statement, it is left to the reader's reason to decide upon the importance of pure air toward sus- taining health. Probably, were stables erected with a little less regard to the proprietor's expense and the builder's convenience ; probably, were they made in some degree proportioned to the magnitude of their future inhabitants, and were the comfort of the captive a very little considered in their construction, — the health of a horse might not be so very telling a proverb ; while megrims, under a better treatment, if it did not dis- appear, might not be so very common. HYDROPHOBIA. 2t HYDROPHOBIA. This is always the fruit of contagion, received from some stable-pet, iu the shape of a dog or cat. It is essentially a nervous disorder. From the first, it influences the brain to a degree which no other malady seems capable of exercising. The animal constantly licks some portion of the body. The place appears to itch violently, and the tongue is applied with an energy and a perseverance highly characteristic of an over-wrought nervous distemper. The appetite always is aflPected; sometimes it is ravenous. The rack is not only emptied with unusual speed, but the bed, however soiled, is also consumed with more than apparent relish. Generally, however, the desire for provender is de- stroyed. Sometimes, the longing for fluids is morbidly increased. The horse plunges his head to the bottom of the pail, will bite at the groom who endeavors to interrupt the draught, or seize the wood between its teeth and crush it with a powerful gripe. More frequently, water will cause spasm, and be avoided with horror. The animal's likings may be morbidly changed: it will occasionally devour its own excrement, and lick up its emissions. The nervous system is always highly developed. The horse starts at the smallest sound, trembles violently without a cause, flies backward, hangs upon the halter, stares wildly, and bursts into a copious sweat without any apparent reason being detected. Its voice is also changed, and the expression of the counte- nance invariably altered. The neigh is squeaking, and the face is at the commencement characterized by immense anxiety, which is soon changed for a peculiar aspect of cunning, mixed with a grinning ferocitv. '^^^ countenance op a horse tvith hydrophobia. Rarely, however, all the foregoing symptoms are absent. The horse is harnessed and taken to work. Suddenly it stops, appears stupid, and threatens to fall. In a short time it recovers, and the labor is proceeded with. The fits occur again and again. At length they end in violent shivering. When the tremor ceases, the recognition is not perfectly recovered. The breathing is quick and sharp; the eye bright and wild. The animal is turned homeward, but seldom reaches the stable before the furious stage begins. 28 TETANUS. Hydrophobia is commonly matured before the expiration of the sixth week, A fortnight is the earliest period of its appearance; but writers have asserted that the imbibed virus will remain dormant for twelve months. The author has no experience which justifies the last opinion. Whenever a suspicion of this incui-able and horrible disorder is enter- tained, place the horse by itself in a building with bare walls, but capa- THE DESTRUCTIVE IMPULSE OF HYDROPHOBIA. ble of being looked into through a window. Put food and water in the house, and, if the door be not strong, have it barricaded. Let no one enter for at least three days, as, during this disease, the horse is both mischievous and dangerous. The pain is such that it seeks relief in destruction. All breathing and moving creatures first attract its rage ; but, wanting these, its frenzy is expended in breaking, rending, and scattering inanimate objects. Its ability to destroy is only limited by the duration of the disorder. Let as few people as possible be near the hydrophobic horse. The quadruped's nerves are then alive to every impression. The presence will be detected, though the person be assiduously concealed. The sound of breathing even adds to the torture. Keep all people away but one; and that one should be the best shot in the neighborhood. Let him approach, aim steadily, and pull the trigger ; for a bullet well placed is the only remedy the author knows which can stay this fearful disorder. TETANUS. Tetanus is defined to be spasm of the muscles of voluntary motion. That definition is right, as far as it goes. The disease, however, is the same in man and horse. The human being complains of the breathing TETANUS. 29 being much oppressed, and of pain at the pit of the stomach. Such complaints show the diaphragm to be involved, while the large doses of strong medicine which can be swallowed with impunity prove the abdominal contents have not escaped. Therefore, the author re^-ards tetanus as spasm of the entire muscular system. A horse of any age may exhibit tetanus. Colts, newly dropped, have displayed the disorder, and all animals are liable to its attacks ; but the very aged are least subject to this malady. Animals of a highly nerv- ous temperament are most inclined toward it. It is said to be of two kinds ; but, in truth, it only has two origins. Traumatic tetanus is when it springs from a wound ; idiopathic tetanus is when it appears without there being any known lesion to account for its presence. It may display its symptoms immediately or within a month of the injury. From the sixth to the fourteenth day is the most likely period for the advent of the disorder. Cold, rain, draughts of air, and too much light, are all likely to ori- ginate it. Their potency, perhaps, ranges in the order they are placed. A gentleman is apt to dismount at some hospitable house and to leave the animal, which has quickly borne him thither, shivering in the night air. The master enjoys himself, probably, more than is good for his health. The patient steed waits and waits, more quietly than the most faithful of human slaves. It shivers in the night air ; its limbs become cramped with the cold. The wind gets up, as the owner, before a cheer- ful fire, mixes another glass and takes another cigar. Still the horse remains almost in the spot where it was placed. The perspiration which covered the body dries in the darkness ; evaporation quickly chills the blood which violent exercise had heated. The pulse sinks; spasms creep over the frame, but there is none near to note them. In solitude and discomfort the most painful of maladies is imbibed: in due time it breaks forth, to the astonishment of the proprietor. Another man rides far and fast through a heavy shower. He reaches a distant house and flings himself from the saddle, fastening the horse to the door-post. Cordials are ready for the man, and business is dis- cussed over a glass. No one thinks seriously of the poor life fastened to the door-post. "The horse is wet and can take no harm." "The gallop home will warm it," and so forth. Therefore, the animal re- mains, to be drenched by the rain and to creep as near to the house as it may for partial shelter; the posterior pai*t of the body, however, pro- jects, and the drops fall, heavy and cold as lead, upon the loins of the patient beast. The blood loses its warmth and the limbs their elasticity. When the owner again crosses the saddle he may be jolly; but it needs both spur and whip to cause the dripping and frozen animal to move. 30 TETANUS. When tetanus originates in some wound, the horse is generally nerv- ous from the first. It fidgets in the stall; it lacks the repose which usually sits so beautifully upon the sick horse's frame. It is excited at the approach of any person, and, commonly, very obstinate when given physic. The wound may, nevertheless, be healthy. Sometimes, as the outbreak draws near, the wound may rapidly close, become morbidly dry, or, instead of pus, send forth only a foul and scanty serum. Instances are narrated of tetanus supervening upon mortification ; but such re- ported cases are, in the horse, very rare. Commonly, the wound pre- sents no appearance by which any man, however profound his knowledge, could guess the consequence to which it had given rise. Tetanus is announced by an appearance of excitement. The tail is erect; the ears pointed forward; the head elevated; the legs stiffened and stretched out. This aspect of excitement is not temporary. The groom passes through the stable and the attitude is main- tained. He wonders "what ails the horse ?" It seems all alive ; yet, though the groom shout out " come over," the order is obeyed with difficulty. The food is not eaten. It is picked and strewed about, but not devoured. When THE TEST FOR TETANUS, WHEN NOT FULLY DEVELOPEB. maStCr TetUmS hOmC, thC grOOm wishes he would "just look " at the horse. It is very strange indeed ! Why, the tail is quivering and the body feels quite hard — not like flesh. Hopes are expressed and the "veterinary" sent for. He proceeds at once to the manger, observing the animal as he approaches. With one hand he raises the horse's head. The haw is projected over the eye, and a case of tetanus is recognized. Most persons know what bellyache and cramp are. Well, these are but spasms affecting different parts of the body : tetanus is spasm affect- ing every part of the body at the same time. The spasm is always pres- ent; but it admits of aggravation. Any painful operation, any sudden fright, or the slightest sound, will produce a paroxysm, during which the horse's body is fearfully contorted ; and the animal writhes as it falls to the ground. Left alone, however, the horse may rise after some time; for nothing causes the quadruped so much dread as an inability to stand. It may totter or fall about, but it refuses to lie down, even though rest must be greatly needed and would act as the best of medicine. It stands day after day in the same spot. It does not move, as any motion may TETANUS. 31 bring on one of those terrible paroxysms. The matter is rendered worse by the brain, during the entire period, being sensible. Every pain is felt, and the wretched animal has leisure to appreciate its agony. This is bad enough; but the torture is aggravated by the appetite of the animal not being dormant. Hunger still exists, and a sense of starva- tion augments the suffering. The jaw is closely locked. The creature cannot feed ; but the presence of hunger is no supposition, for if a mash be held to the mouth, with a look of piteous gratitude the liquid portion is often drawn through the closed teeth. Hunger frequently impels the horse to make a desperate effort. The jaws are forced a lit- tle way asunder; a morsel is seized between the incisors; mastication commences, but cannot be perfected. The agony attendant upon motion forces the famishing creature to desist; and the poor horse is often found with a mouthful of hay firmly clenched and hanging from the mouth. The animal may have been conspicuous for its beauty. The harmony of form may, in it, have been united to agility of limb. The creature SHOWISa HOW PAR AN ANIMAL WITH THE DISEASE IS CAPABLE OP MOTION. may have been the pride of its proprietor ; but a few days of this disease will work a mighty change. The limbs are moved with difficulty ; the body has lost all its undulating grace; and the flesh has parted with its elasticity. The master in vain seeks for the object of his admiration in the painful sight which he then looks upon. 32 TETANUS. One peculiarity of tetanus is too marked not to be noticed. Persons have complained of the wooden appearance of the body; but, in severe cases, the height of the animal seems diminished and the length shortened. This appearance is more than the result of mere imagination. Many of the bones are divided by a fibro- cartilaginous substance: this substance force can compress. For that reason, a man is shorter when he retires at night than when he rises in the morning. No weight, however, can act with the energy of excited contractibility, and of that tetanus is composed : all the muscles are violently in action or energetically con- tracting. A single muscle, when excited, shortens to that degree, which moves some portion of the body, but, when the entire mass of muscles simultaneously contract, they compress the frame, as in a vice. The grace of the animal is lost; the height is diminished, and the length is lessened, under so powerful and general an action. All kinds of treatment have been tried for tetanus, and it is said that each has resulted in success. The majority of these popular methods, however, are sheer barbarities ; and if they were successful, they were so against probability. The plan at present adopted is much more humane : the animal's shoes are removed, that no sound may follow the tread, and a solitary shed is strewn with refuse tan. Food, in the form of an ample malt mash and a pail of thin gruel, is placed within easy reach. The shed must be approached but once daily — then by the man most accus- tomed to the horse ; and he speaks soothingly as he nears the building to change the provender. This species of treatment, when preceded by a large dose of purgative medicine, is usually successful. Mix four drachms of aloes or six drachms of aloetic mass, and four drachms of extract of gentian, with one scruple of croton ferina. This tremendous purgative may be confidently given, as everything during this disease depends upon the maintenance of quiet, and upon getting the bowels open. As all people, however, may not live where solitude can be com- maiided ; then, give the purgative, render the room dark, and allow as few cui'ious visitors as the pleading of sincerity cannot prevent intruding upon the sick and disabled quadruped. Pulling the animal about to administer medicine seems to do more harm than the most powerful drugs can counteract. Permit no blisters; sanction no firing: counter- irritants, however beneficial in other cases, are positive irritants, when applied to a body nervously excited to the highest degree. Grant per- mission for no operation to be performed, as any person of ordinary imagination may picture the effect of bustle, followed by sharp pain, upon a creature which cannot endure even the slightest sound. Should, however, the case last so long as to warrant fear of the STRINGHALT. 33 life sinking through starvation, food may be given even in quantities. Blood-warm linseed gruel should be procured — a gallon will be sufficient. THE MODE OF FEEDING A HORSE WITH CHRONIC TETANUS. The horse could swallow more ; but after a prolonged fast there is danger in loading the stomach. Fix the horse catheter to the stomach-pump ; then place the free end of the catheter in the nostril of the quadruped and push it forward, having previously slightly bent the end of the tube downward. Should the insertion provoke coughing, withdraw the catheter and commence afresh. Two feet of the instrument having dis- appeared, and no alarming symptom being present, begin to pump ; do this as fast as possible, till the gallon of linseed gruel has been ex- hausted : such a resort is, however, better adapted to tetanus of the chronic description. When applied to the acute form of the disorder, it is too apt to induce violent spasm. The acute disease, however, speedily terminates, and positive starvation is all but impossible during its brief continuance. STRINGHALT. Stringhalt is the imperfect development of that form of disease which, in man and in dogs, is called chorea, or St. Vitus's dance. In dogs it jerks the whole body, even to the face. The lower jaw will continue moving and the eye twitching, while the animal is prostrate and asleep. In the horse, however, it is seen only in the hind extremities. In the dog it will continue during progression, sometimes shaking the creature from its balance, and it often terminates in death. In the horse it is never fatal ; and, save when about to start, is seldom to be detected. Then it causes the hind limbs to be quickly raised in succession. The movement is rapid, full of energy, and entirely involuntary. These 3 34 STRINGHALT. motions over, the horse proceeds, nor is the symptom usually witnessed again till the animal has once more to start ; although a few exceptional cases are on record where stringhalt was perceptible at every step. A HORSE HAV1N3 STRINGHALT MUST MAKE SEVERAL INVOLUNTART MOVEMENTS WITH THE HIND LEGS BEFORE IT CAN PROGRESS. Guilford, the racer, exhibited the disease in its worst form. In that animal, stringhalt was present in such severity as prevented the signal being obeyed before the several eccentric movements had been performed. The horse was esteemed good for its purposes ; but the ground lost at starting gave away its chances, and it was consequently sold. From the pampered stable of the race-horse, it descended rapidly through various grades until the creature came to be harnessed to a London omnibus. While in that position, the disease was so aggravated that the pastern used to hit violently against the belly, till the hair of both was partially removed by the repeated blows. The Society for the Prevention of Cruelty then purchased the miserable carcass for three pounds, and had the life and the suffering extinguished. The body was given to the Royal Veterinary College for dissection. Professor Spooner relates that he found blood effused on the sheath of the sacro-sciatic nerve. This, however, must have been an accident pro- duced by the death struggle: that nerve moves the flexor muscles. Stringhalt is the disease of the extensor muscles only; therefore, the S T R 1 N G H A L T. 35 condition of the nerve alluded to by Professor Spooner could in no way- influence the motions of the limb. Messrs. Percivall and Goodwin both appeal to instances, where, in animals affected with stringhalt, pressure existed upon the posterior portion of the spinal column. The last ob- servation accords much more with the writer's notions of cause and effect. Nevertheless, the inexperienced reader may ask, how can the posterior portion of the horse's spinal column become affected ? Of all the ver- tebrae, those of the lumbar region are endowed with the greatest motion, and consequently are the most exposed to injury. The uses to which man puts the animal are not so very gentle but a delicate structure, however deeply seated, might be hurt. However, grant all these are harmless, which is indeed to allow a great deal to pass, the stables are enough to provoke stringhalt in half the horses now resident in London. Has the intelligent reader visited these places ? He knows the holes in which poor humanity is obliged to stive. Well, any place not good enough for a man to live in is esteemed luxurious lodging for a horse. Many of the places are undrained ; frequently have light or air admitted only by the doorway, and the stalls are seldom more than four feet wide. The wretched captives cannot turn their bodies round in the allotted space. A horse being in, when wanted abroad, must be backed into the gangway, and thus made to "face about." It is not creditable to human nature when we perceive its most valuable and willing servant is be- grudged the space in which its useful body rests. The labor of the day should at least earn for the horse a sufficient bed. The exhaustion of the toil — for man has nicely calculated the work a horse can perform, and generally exacts the quotum to the full — has merited the night's repose, which shall fit for the morrow's fatigue ; but man is most particular in all that concerns the quadruped. He has reckoned up the food it may eat, the water it may drink, the space it may occupy ; the keep, the keeper, the lodging, and the very harness that fastens it to the load, — all are precisely calculated. There is no law to interpose between man and horse, even should the estimate be run "too fine." Against sore shoulders there is some enactment, which is only enforced through a constable specially retained by a private associ- ation. No clause teaches man his duty toward his inferiors. The lower animals have no protection against the exhausting labor and inadequate provision that maims a body or wastes a life. The servant, observing the master to be without feeling, apes his better. A bad example always finds plenty of imitators. The horse may be wanted in a hurry; the groom commands it to "come round." It is too much trouble to back the animal as usual ; the master is in 36 PARTIAL PARALYSIS. haste and the servant has no time to lose. The poor animal endeavors to obey ; it squeezes and twists its body : the head is seized, a blow is given, and the difficulty is vanquished. But at what a cost ! One bone of the spine has been injured. Bone is slow in its developments. No immediate consequence results; but months afterward, the injured place throws out a spicula of bone, no larger than a needle's point, perhaps, but it presses upon the spinal marrow, and lasting stringhalt is the effect. Of course no drug can reach the part affected ; no cunning prepara- tion can remove even a needle's point from the interior of the sjiinal canal. The stinghalt, once exhibited, is beyond cure, and never disap- pears but with the life. However, it mostly affects high-spirited, nerv- ous horses, and not being generally observable during progression, some of the quadrupeds thus diseased sell for large sums. PARTIAL PARALYSIS. Paralysis, in the horse, save when it appears toward the termination of violent disorders, is never more than partial. It locates itself in the THE UNSTEADY WALK OF A HORSE -WHEN SUFFERING UNDER PARTIAL PARALYSIS OF THE HIND LEGS. hind limbs, and, though it does not destroy all motion, yet it destroys all strength or utility. The power to move with speed is entirely lost, nor is the ability to progress at a slower pace by any means assured. One PARTIAL P All ALY SIS. 37 hind foot is perpetually getting in the way of the other, and constantly threatening to throw the animal down, whose walk already is rolling or nnsteady. This affection is the property of matured animals ; so rarely as to be . exceptional is it to be seen attacking colts. Fast trotters, omnibus horses, hunters, and creatures subjected to extreme exertion, are most liable to it. It creeps on insidiously. At first the pace is as fast as ever; but something is suspected wrong in the manner of going. After a time the creature is brought to a veterinary surgeon as a lame horse. The suspicions are then destroyed and the real malady is announced. The decay of the more showy powers seems to bring forward the gentler qualities of the horse's nature. The animal, which once was dangerous, loses all its dreaded attributes: with paralysis, it becomes meek or tame, as though the big life felt its great affliction and sought to compensate, by amiability, for the trouble it necessarily gave, or, in other words, that the animal, was mildly pleading for existence. No doubt much of such a sentiment, if not all, resides in the mind of the spectator, the animal only being subdued by sickness. Still, it is very sad to contemplate the horse, which once could outstrip the sparrow in its flight, reduced to a pace which the tortoise might leave behind ; to behold the beast, once powerful and proud of its strength, humbled to a feebleness which the push of any child might overthrow. It is more sorrowful, when we think its hurt was received from him to whom its welfare was intrusted ; that its injury was the consequence of an over- anxiety to please and to obey. It may be well doubted whether, when man was given dominion over the beasts of the field, he was invested with an absolute authority over God's creatures, which had no moral duties nor obligations attached to it. At all events, it would be difficult to find an object more suggestive of pity, or better calculated to excite our inward reflections, than a horse suffering under partial paralysis. Paralysis is generally past all cure ; occasionally, however, it admits of relief. It is an eccentric disorder, and it is difficult to saj'^, positively, what medicine will be of use. The horse, however, during paralysis, should enjoy absolute rest. In its disabled state, a little walk is as great an exertion as once was a breathing gallop ; and it M'as over- exercise which induced the disorder. The animal should receive only strengthening physic and the most nourishing of food. The following ball should be administered, night and morning : — Strychnia, half a grain, gradually, or in six weeks to be worked up to a grain and a half ; iodide of iron, one grain ; quassia powder and treacle, a sufficiency : to be given night and morning. The grooming should be persevered with, the animal being carefully 38 GUTTA SERENA. dressed twice each day, and the process ending by brushing the quarters thoroughly with a new birch broom. The bed should be ample; the box should be padded and a warm cloth always kept over the loins. A piece of wet flannel, covered with a rug, placed over the lumbar region, has on occasions induced a return of warmth. The bowels should be regulated, if possible, with mashes and green meat; but, when costive- ness exists, a pint of oil is to be preferred to even three drachms of aloes. The one exhausts, the other nurtures as well as relaxes the body. The hope of amendment must, however, be indulged with caution. The disease is of chronic growth, and therefore will be of long duration. At all events, it is not one horse in four which recovers from an attack of partial paralysis; and not one in twenty that is afterward fit for its former uses. GUTTA SERENA. Gutta serena is fixed dilatation of the pupillary opening, owing to paralysis of the optic nerve; the affection is, consequently, accompanied by permanent blindness. The causes of this malady are blows upon the head, quick driving, excessive hemorrhage, stomach staggers, unwholesome stables, poor food, exhausting labor, or anything which may decidedly undermine the constitution. The majority of these causes are inflicted by man, the remainder are within his control. Any person has but to reflect how very precious eyesight is to mankind. Having settled that point, he has only to con- jecture how much more dear it must be to a creature forbid to enjoy the pleasures of conversation. To take away sight, is to deprive the animal of a faculty with which it is endowed to perfection, in some measure to compensate for the absence of reason and the deficiency of speech. A horse can see farther than its master. The human eye is, frequently, dormant, when the thought is active : the healthy, equine eye never rests. The creature sleeps so lightly that very seldom is it caught napping. We may imagine, therefore, the gratification bestowed by an organ so constantly employed. To blind a horse, is to deprive a breathing body of half its life's pleasure. It is more, when we consider the natural disposition of the quadruped : it is to deprive timidity of its watchfulness, fear of its protection. It is even yet more, when we think upon the habits of the horse — its spirits, its pleasure, its joy — all are expressed by means of a gallop. But what speed can the horse indulge in, when cruelty has taken away the power to guide with rapidity ? To destroy the horse's sight, is to condemn a creature to live on, but to take from life the gayety of existence. GUTTA SERENA. 39 The eye recently afflicted with gutta serena, or rather the eyes, (for this deprivation commonly aifects both orbs,) is, to the uninformed inspection, perfect. The internal structures are in their proper places, and the pupil is beautifully dilated. A very little instruction, however, enables the spectator to distinguish between fixedness and dilatation. A trifle more tuition will point out that the pupil is not so dark as in the organ of the healthy animal : that it has an opaque milky cast, accompanied very frequently with a bright light-green shining through it, as though a piece of tinsel were within the posterior chamber. After gain- ing such information, probably the notion before expressed about beauty may be changed. Most things are most beautiful as nature formed them, and no little expression resides in the ever-changing dimension of the pupillary opening. AN EYE AFFECTED WITH GUTTA SERENA. ^^pJVV'^ THE MODE IN WHICH A HORSE, WHEN QUITE BUND, PROGRESSES. The symptoms of blindness are equally pathetic and characteristic. The nostrils are constantly at work and the ears perpetually in motion — life is endeavoring, by exercising other senses, to compensate for the one lost. Then, the movements are peculiar. A blind man commonly 40 GUTTA SERENA. shuffles along, endeavoring "to feel" his way. The horny hoof lacks the human faculty, but the horse endeavors to surmount objects by step- ping high. A blind man turns the sightless face heavenward; the animal, likewise, raises its head, as it were, to expose its sightless orbs to its Creator. There is another strange peculiarity also, exemplified by the blind horse. The sightless quadruped, contrary to the majority of its species, generally carries a rough coat in summer and a blooming coat in winter. Now, a high stepper, a well-carried head, a lively ear, and a blooming coat, are great points in a horse, especially about London, and with gentlemen of little information. To prevent imposition, always place the horse in a fuir light. Should the pupils continue large, have the horse put into a dark house. A quarter of an hour afterward, take a candle, and by its light regard the eye. If the pupil is still dilated, hold the candle near to the eye. The iris will not contract quickly upon artificial light, but in five minutes it ought to move. However, suppose you imagine it to remain stationary; then, placing yourself by the head, have the horse led out into sunshine. If it exhibit no change to mark the passage from dark- ness to daylight you may certainly con- clude the optic nerve is paralyzed. There are other tests, but these are not satisfactory ; such as covering the eye with the hand or a hat. The hand is semi- transparent, and so can only induce par- tial darkness ; the hat does not fit the inequalities of the horse's countenance, therefore it is useless. Of the same nature is aiming pretended blows at, or moving the hand before, the suspected eye. The other senses, by constant exercise, become so very acute during loss of sight, that winking is no proof of vision : the lid may move, and, nevertheless, the horse be stone blind. Nothing can be done for paralysis of the optic nerve. The injury once es- tablished, its effects are lasting. Butchers and other people, who foolishly pride themselves upon their fast trotting steeds, and whose natures are not unpleasantly susceptible, often induce the afifection. It lessens the value THE BASE OP THE BRAIK. a. The point of junction between the right and left optic nerves. 6 6.

GUTTA SERENA. 41 of the horse, dooms it to a lower class of proprietors, and takes from the creature's life much of the pleasure which otherwise might lighten the animal's existence. After death, an anatomical peculiarity is observed. The optic nerves, subsequent to leaving the brain, unite and exchange fibers. Neither nerve pursues an absolute course; yet, consequent on decease, if the right eye were blind from gutta serena, the left nerve, or the nerve originating from the left side of the brain, alone is affected : the disease seems confined to that part. The opposite nerve is perfectly white and healthy; but the one affected with paralysis is of a yellowish color, softer nature, and sensibly diminished in bulk. So, if blindness afflict both eyes, both optic nerves are then of diminished size and of a yel- lowish hue. CHAPTER II. THE EYES THEIR ACCIDENTS AND THEIR DISEASES. SIMPLE OPHTHALMIA. The following engraving illustrates some of the accidents which attend upon injured sight in the horse. The eyes are probably more important to the safety and pleasure of the master than any other por- tion of the quadruped's frame. Let the smallest impediment exist, and SOME OF THE RESULTS OP IMPERFECT VISION. there is no telling in what way it may operate. Certain horses are most affected by near objects; others exhibit alarm only when bodies are approaching them; another class of creatures will look upon most for- ward sights with indifference, but will invariably be horror-struck when- ever the view is extensive ; while a fourth group will shy violently with- out mortal vision being able to recognize any cause for terror. In every case, the dread excited overmasters all other feelings. The presence of extreme fear releases the horse from the dominion of its proprietor; its movements are sudden, jerking, and eccentric; the animal has lost all self-control, and there is no saying in what direction it may move or what it may attempt to do. It is regardless of its own life, therefore (42) SIMPLE OPHTHALMIA. 43 it is careless about the welfare of others, and he is very fortunate who possesses such a servant and escapes without accident. There is no cure foi; a disposition depending upon a change of struc- ture ; but there may be a preventive. Would all horse-owners preserve their tempers and forbear from slashing a horse over the head, they would be vast gainers in a pecuniary sense, and would certainly escape very many of those ills now commonly attendant upon equestrian exer- cises. Whoever has a shying horse had better discard the ci-eature from all private uses. Send the animal to some work in which the habit will be accompanied with less danger, or never allow the quadruped to quit the stable without having the sight securely blinded. Such things are necessary; but the. feeling man, when he considers how much the exer- cise of the senses sweeten mere animal existence, will sigh over the order which compels him to deprive a horse of that which the common sense of the English has denominated "precious sight." Simple ophthalmia is inflammation of the fine membrane which covers the horse's eye ; it reaches no deeper, it does not affect the internal structures of the organ, and it is not so much to be dreaded in its immediate as in its after consequences. It is caused by accident and by the violence of man. As the reader has walked the streets, he surely must have seen men indulge their temper by cutting a horse over the head with the whip. The animal capers about and shakes the ears, endeavoring to avoid the chastisement; the man becomes more enraged; the reins are pulled tight, while the master stands up in the gig, and for minutes continues chastising a creature that is bound to the shafts and comparatively at his mercy. Were the horse, thus tortured, to run away, the person who abused his authority would have provoked a severe retribution; but the animal has no such intention. The fault may be far more imaginary than real. The timidity of the horse prevents it from will- fully inviting the dreaded lash; possibly the offense resides more with the individual invested with trust over life than with the creature that patiently submits to most unworthy control. At all events, the thong curls about the face ; now it cuts the lips, in which the sense of touch resides; the pain is maddening, the horse capers and shakes its head, striving to avoid a repetition of the torture. The next slash, however, turns sharply round the blinkers and lights upon the eye ; the horse is held tight, the man feels happy, he has discovered a tender place ; the whip is plied again and again, always falling true. It hits the mark. When the animal reaches home, the lid of one eye is closed, and many tears have wetted the cheek, while scars remain after the immediate 44 SIMPLE OPHTHALMIA. consequences have passed; the vision is interfered with, and timidity becomes an inveterate shyer. Also, from the manner in which the rack is placed, a hay-seed fre- quently falls into the eye. The hay is always kept in the loft above the stables, and a narrow trap-door opens into the rack. This is very con- venient for the groom; how could any architect be so very "maudlin" as to design a stable with the slightest consideration for a horse ? At every mouthful the head has to be raised and the provender pulled out; probably, human ingenuity could not invent a machine more likely to be attended with injury. The head uplifted, the eye open to direct the bite, the dry grass shaken to pull out the morsel, of course the loose parti- cles are dislodged, and what wonder if one of the hay-seeds should fall into the open eye ? This body is small, dry, harsh, and sharp ; moved about by the motion of the lid it commits fearful ravages upon the tender organ to which it has found admittance, and simple ophthalmia is the consequence. Man is too proud to learn from nature, or he might observe horses always depress their heads when in the field. The common parent, with care for all her children's comfort, makes the animal stoop to crop the herbage; man causes the creature to upraise and outstretch the neck to reach its sustenance. However, the horse is not always free from acci- dents when it quits the stall. Carters often amuse the weary way by striking what they term a "stubborn and foolish horse" over the head with the butt end of the whip. This action, though most irritating to witness, is generally less important in its results than any of the injuries previously remarked upon. The lid shields the eye ; consequently, a largely swollen covering and a slightly injured membrane are the conse- quences. Many brutal drivers have "a happy nack" of kicking at the head of a fallen animal to make it rise. This act may extinguish vision or pro- voke simple ophthalmia ; but, it is hoped, all such are exceptional cases, therefore these are willingly not remarked upon. Frequently horses try to while away the long hours of confinement by playing with one another; one horse will lean its head over the divi- sion to the stalls and for hours together lick its fellow prisoner's neck. Sometimes a day's rest begets high spirits, and the animals indulge in a more boisterous amusement ; they bite and snap at one another's heads. Domestication has, however, disabled the creature to nicely measure dis- tances ; standing all day long with the nose close to a glaring white wall has probably impaired the vision. One horse projects its teeth too far; they simply graze the eye ; but a small flap of membrane is the conse- quence. The bite of au enraged horse is fearful ; and were not the SIMPLE OPHTHALMIA. 45 A READY MODE OP BLINDING A HORSE, AM) OF APPLYING A LOTION TO THE EYES IN SIMPLE OPHTHALMIA. animal gently inclined, more than a minute portion of fine skin would testify its intention. Simple ophthalmia, accompanied with a small abscess upon the cornea, is the result. The treatment of simple ophthalmia is somewhat homely. Put on a bridle, or a leather head-stall ; or a halter will answer the purpose ; fasten a cord loosely to either side, so that it may cross the forehead ; on this line suspend a cloth several times dou- bled ; but, mind it is large enough to cover both eyes, for the visual organs are so sympathetic, that when one is in- flamed the other is very likely to exhibit disease. Keep the cloth continually dripping with the following lotion. Fill a two-quart saucepan with poppy heads, cover these with water; boil, till the poppy heads are quite soft ; pour off the liquor, strain, filter, and, adding thereto one ounce of tincture of arnica, the preparation, when cold, is fit for use. On the first morning, an inspection should be gently attempted ; for the eye is generally so very tender, and the animal so resistful, that no examination at that time is generally satisfactory. On the following day, however, the lotion will have reduced the swelling, mitigated the agony, and have enabled the horse to be more obedient ; then make another and a thorough examination. The skin upon the eye will be white and opaque, the lining of the lid inflamed, while numerous tears will pour down the cheek according to the severity of the injury. Re- move any substance found underneath the eyelid. If the hay-seed or sharp particle shaken from the provender stick firmly into the outer covering of the eye, grasp it tightly with a pair of forceps, and endeavor to pull it out. Should it be fixed too deeply for any ordinary force to move it, do not exert all your power, but take a sharp-pointed knife, which is better than a lancet, because more under command, and placing its tip below the ob- stacle, with a motion, of the wrist oblige it to quit its situation or to come forth between the ends of the forceps. Should a flap of the cornea be left by a bite, probably pus will be secreted beneath it; the place must be watched till the local inflamma- tion has subsided, and a spot of yellow, opaque matter can be detected AN EYE RECENTLY AFFECTED \TITH SIMPLE OPHTHALMIA. 46 SPECIFIC OPHTHALMIA. under the transparent membrane. With a slight incision the pus must be released and the eye bathed with a lotion composed of water and chloride of zinc, one grain to the ounce. Other cases will rather be known by the variety of marks left behind than by any difference in their necessary treatment. A lotion is gen- erally everything required; however, should the inflammation become excessive, it may be necessary to open the eye-vein or the vessel which, journeying toward its larger trunk, runs directly beneath and from the eye. When this prominent and visible vein is pierced, it frequently, although distended, will not bleed. Then place some favorite food upon the ground, — the bending of the head and the movement of the jaw will cause the current to flow forth freely. It is among the most beautiful attributes of the horse, that though so very timid, it never suspects nor can it understand actual injury. Thus, the flowing of its own blood does not affect it; it is otherwise with other animals not more intelligent. If a dog or cat be hurt, no delicacy can tempt the creature to feed. The horse, when in battle deprived of its limb, is so accustomed to restraint and so unsuspicious of harm, that it has been found, after the strife was ended, maimed, and yet cropping the herbage about it. The generous beast, when domesticated, retains its gentle disposition, and soon forgets to recognize danger; it becomes attached to its superior, and though its treatment be coarse and its usage brutal, it can pardon all. The consequences of simple ophthalmia are little, white, opaque spots upon the membrane. Streaks of the same sort are occasionally left upon the organ by the abuse of the whip ; the amount of blemish, of course, will be decided by the original injury. Never purchase an animal thus disfigured ; better buy a blind horse. The opaque places prevent many rays of light from reaching the optic nerve; the sight is irreparably im- paired; the horse sees imperfectly; it may be- hold the head of a man, while the opaque scar HORSE'S EYE INJURED BY THE coucBals thc body. Timidity takes alarm at the apparently spectral object. It has no reason to explain, and it wants intelligence to understand. The poor abused quad- ruvied becomes a dangerous shyer. SPECIFIC OPHTHALMIA. Before we touch upon the subject which forms the heading to this article, we wish to establish one proposition, because it will smooth the way to an understanding between author and reader. SPECIFIC r II T II A L M I A. 47 Man cannot make a property of life ; he has no power over its con- tinuance; it may cease to-morrow without his permission and against his wishes ; it is removed from and independent of his control. Man can have nothing like a property in that which is altogether above his sway. He then, obviously, has no right to enslave any living creature, and take no care of the existence which he has deprived of liberty to provide for itself. When he captures a wild animal and retains it in captivity, he entails upon himself the duty of providing for its wants, and becomes answerable for its welfare. He violently usurps nature's province — obviously, he adopts nature's obligations ; if he rebel against such a moral contract and persist in viewing dominion as absolute authority, as something which invests him with power to feed or starve at his pleasure, house or turn into the air according to his will, nature opposes such arrogance, and, releasing the life by death, takes the op- pressed creature from the tyranny of the oppressor. Under some such compact the horse is given to man. The implied, not written obligation, may not be acknowledged or understood; but, nevertheless, it exists, and the terms of the bond are rigidly exacted. Let us regard this matter in relation to specific ophthalmia. A gentle- man possesses five horses ; he builds a stable twenty feet long, twelve feet wide, and nine feet high ; into this place he crams the five huge lives. We will suppose the place to be good of its kind, to be paved with Dutch clinkers and to be perfectly drained ; still each horse stands in a stall four feet wide ; in this it has to remain all night and the major portion of the day. In this space it has to relieve its body; the liquid, to be sure, may run off by the drain, but it has to fall upon straw, which imbibes some, and to flow over bricks, which absorb more ; the solid excrement is during the day removed by the groom as it falls, but it re- mains in an open basket to taint the air of the place. We will suppose the horses and their at- tendants, occasionally, are the sole inhabitants, and the building contains none of those things, living and otherwise, which ladies are pleased to order should "be carried into the stable." Will the sane reader assert that the space is large enough for its purposes ? The stable never can be sufficiently ventilated : it will smell of impurity — of hay, straw, oats, ammonia, and of various other things. The air feels hot. Can it be wondered at? Ten large lungs have been breathing it for weeks and years, during twenty out of every twenty THE SPECIES OF ETE 'wnirn I-^ GEXERAI.lv supposed 1 ) HE MOST LIABLE TO OPHTHALMIA. 48 SPECIFIC OPHTHALMIA. four houi's. Five huge creatures have been cabined there, living by day, sleeping by night, feeding and performing all the other offices of nature. Is it astonishing that the air feels and smells close ? Ought we not rather to wonder that animal life can exist in such an atmosphere ? The chief contamination is ammonia; ammonia will not support vitality. The reader has inhaled smelling salts ; those are purified carbonate of ammonia ; have these not made the eyes water ? The ammonia of the stable affects the eye of the horse ; it also undermines the constitution ; but, by constantly entering upon the lungs and stimulating the eyes, it causes the constitutional disease to first affect the visual organs ; in short, specific ophthalmia is generated. Now, to prove the case here stated. In the south of Ireland, where poverty prevails, humanity is obliged to shelter itself in strange places, and any hole is there esteemed good lodging for a horse. In that part of the kingdom ophthalmia affects the majority of animals; it not only preys on horses, but it seizes upon mankind ; for the author, a few years ago, was much struck by the quantity of blind beggars to be encountered in the streets of Cork. Here we have the conclusion of the argument ; its moral exemplified and enforced. If animals are foully housed and poorly kept, they generate disorders, which at length extend to the human race ; therefore he who contends for a better treatment of the horse, also indirectly pleads for the immunity of mankind from certain diseases. Man cannot hold life as a property, or abuse life without his ill deeds by the ordinances of nature recoiling on himself. Specific ophthalmia is a constitutional disease affecting the eyes ; it has been submitted to all kinds of rude treatment; no cruelty but has been experimented with ; no barbarity but has been resorted to. It has been traced to various sources ; its origin has been frequently detected ; but the real cause of the disease, to this day, has not been recognized. The veterinary surgeon is often sent for to just look at a horse which "has got a hay-seed in its eye." This mistake is very common, as ophthalmia gen- erally breaks forth during the long night hours, while the stable is made secure and the confined air is foulest. The groom sees an animal with a pendant, swollen lid, and with a cheek bedewed by copious tears ; he can imagine only an accident; but the medi- cal examiner must obey the summons with an unprejudiced mind, because simple oph- thalmia is a mere misfortune, specific ophthalmia is a constitutional disorder. THE FIRST APPEARANCE OF SPECIFIC OPHTHALMIA. SPECIFIC OPHTHALMIA. 49 The veterinary surgeon, firstly, in the groom's convictions, makes a grievous mistake. He goes up to the horse on the opposite side to the affection ; being there, he takes the pulse, remarks the breathing, observes the coat, feels the feet, examines the mouth, and looks at the nasal membrane. If simple ophthalmia be present, some of these may be altered from long-endured pain ; but if specific ophthalmia exist, the general disturbance denotes a constitutional disorder. The pulse is hard, the breathing sharp, the coat staring, the feet cold, the mouth clammy, and the nasal membrane inflamed or leaden-colored. The horse is next ordered round to the stable window, with the dis- eased eye toward the light. A pretense is then made of forcing the lid open; if simple ophthalmia be present, the resist- ance is energetic, but not violent. Should specific ophthalmia be the affection, the horse struggles against the intimation with the wildness of timidity, striving to escape a terrible torture. The animal is, there- upon, brought into some shady corner ; its fears are allayed, and it permits the lid to be raised with little difficulty. Should the eye have been injured by an accident, the most prominent part of the ball is likely to be hurt. The internal structures are unaffected ; the pupil generally is larger than usual, and the iris is unchanged. The haw may be or may not be projected ; but the eolor, form, and aspect of the iris is unaltered. During the commencement of specific ophthalmia, the center of the cornea may be transparent, but the circumference of the ball is violently inflamed; the reason being that a constitutional disorder always first attacks the more vascular structures, and, therefore, commences in the RAISING THE UPPER LIB OP AN EYE AF- FECTED WITH SPECIFIC OPHTHALMIA.

In specific ophthal- mia, thq, color of the eye has changed to a lighter hue, and the pupillary opening is firmly closed, to prevent the entrance of the dreaded light. 4 50 SPECIFIC OPHTHALMIA. Weakness increases as specific ophthalmia progresses. The attack, however, is seldom stationary ; the eye first involved may suddenly become clear and healthy, and the opposite organ may exhibit the ravage of the disease ; thus, the afi"ection keeps rapidly moving about ; when it sud- denly quits both eyes, the inflammation commonly fixes upon some dis- tant part of the body, as the lungs or feet. No one can predicate how short will be its stay or how long the attack may last ; it has disap- peared in a week, it has continued two months. It seldom reaches its climax during the first assault. It will occur again and again ; generally it ends in the destruction of one or both eyes ; but never, so far as the author's knowledge extends, causes gutta serena. Like scrofulous affec- tions in the human being, which it greatly resembles, it generally is the inheritance of youth ; after maturity or after the eighth year has been attained, it is rarely witnessed. When this terrible affliction visits a stable, let the proprietor firmly oppose all active measures. A shed ought to be procured, cool or shady, and screened on every side, excepting on the north. Every hole, how- ever minute, should be stopped, because light shines through a small opening with a force proportioned to its diminutiveness. The stars and candles in the once popular London Diorama were only small holes cut in the canvas. The eye-vein is then to be opened, and the lid, if much enlarged, punctured in several places ; when the bleeding has ceased, a cloth, saturated in cold water, is to be put over both eyes. As to other reme- dies, they must be regulated by the condition of the animal. Should it be poor, oats and beans, ground and scalded ; cut green meat ; gruel made of hay-tea, etc., should be given. No dry fodder must be allowed ; all the provender must be so soft that mastication may be dispensed with. The movement of the jaw, sending blood to the head, is highly injurious during an attack of specific ophthalmia. Let the following ball be given twice, daily : — Powdered colchicum Two drachms. Iodide of iron One drachm. Calomel One scruple. Make into a ball with extract of gentian. Observe the teeth while this physic is being taken. The author has taken twenty-five grains of calomel daily, for a month, with impunity; lately, he was slightly salivated by two grains, when not expecting any efifect. Mercury, therefore, operates in accordance with the system; it is strong or weak as the body is sickly or robust. Should the animal be fat, do not therefore conclude that it is strong ; SPECIFIC OPHTHALMIA. 51 obesity is always accompanied with debility. But if the horse be a hunter or a racer, in training condition, still give the medicine pre- scribed, with soft food, not quite so stimulating, and the ball twice daily. However, as soon as the medicine begins to take effect, which it will do soonest upon the weakly, change it for : — Liquor arsenicalis Three ounces. Muriated tincture of iron Five ounces. Mix, and give half an ounce in a tumbler of water twice daily. Do not bother about the bowels ; endeavor to regulate them by mashes and with green meat; if they should not respond, do not resort to more active measures. Should the pulse be increased, a scruple of tincture of aconite root may be administered every hour, in a wineglass of water; should the pain appear to be excessive, the like amount of extract of belladonna may be rubbed down in a similar quantity of water, aud be given at the periods already stated ; only always be content with doing one thing at a time. Thus reduce the pulse, for, with the lowering of the vascular action, the agony may become less intense; however, so long as the beats of the artery are not more in a minute than sixty-five, and not very thin or hard, the aconite should be withheld, for during an acutely painful disorder the heart must be in some degree excited. The grand measure, however, remains to be told. Remove every horse from the stable in which the attack occurred; then elevate the roof, widen the gangway, and enlarge the stalls; improve the ventilation, overlook the drains, lay down new pavement — in fact, reconstruct the edifice. It is felt that, in giving these directions, a proposal is offered to demolish a building. The author is fully alive to the expense of such a transaction; but one valuable horse will pay for a great deal of bricks and mortar. Experience has decided that the most humane way is, in the long run, the cheapest method of proceeding. Ophthalmia is a teasing and a vexatious disorder. If the owner has no feeling with the inhabitants of his homestead, still let him study his own comfort, for it is astonishing how very much good stabling adds to the appearance and to the happiness of a mansion. Specific ophthalmia does not terminate in death ; it usually leaves the victim blind in one or both eyes. In England, however, it is mostly satisfied with the destruction of one organ; the strength of the other becoming, after its departure, considerably improved. At the same time, having caused the lids to swell, it leaves them in a wrinkled or a puckered state ; the remaining eye is likewise somewhat sensitive to light. To gain in some measure the shadow of the brow, and to escape the full glare of day, the eye is retracted; all the muscles are employed 52 SPECIFIC OPHTHALMIA. AN EYE DISPLAYING THE RAVAGES OF SPECIFIC OPHTHALMIA. to gain this end, but tlie power of the levator of the upper lid causes the eye to assume somewhat of a three-cornered aspect. It is always desirable to recognize the animal which may be or may have been liable to so fearful an affection. One symptom of having experienced an at- tack is discovered on the margin of the trans- parent cornea. The inflammation extends from ,'^ the circumference to the center. The margin III' I of the transparent ball is generally the last '' ' place it quits; here it frequently leaves an irregular line of opacity altogether different to and distinct from the evenly-clouded indica- tion of the cornea's junction with the sclerotic, which last is nattiral development. Nevertheless, the internal structure best display the ravages of specific ophthalmia ; it is upon these the terrible scourge exhausts its strength. The eye becomes cloudy; loses its liquid appearance; the black bodies attached to the edges of the pupillary opening either fall or seem about to leave their natural situation. The pupil becomes turbid, then white; the iris grows light in color, and at last remains stationary, having pre- viously been morbidly active. The whiteness of the pupil grows more and more confirmed, and every part grows opaque; by this circumstance, the total cataract, arising from specific oph- thalmia, is frequently to be challenged. The lens, moreover, is often driven, by the force of the disease, from its position; it lodges against the inner surface of the globe. Very common is a torn or ragged state of the pupil witnessed, as was stated, during the intensity of the at- tack, for the iris contracts to exclude the light ; remaining thus for any period, it becomes at- tached to the capsule of the lens; when the disease mitigates, it often rends its own structure by its efforts to expand. Should those efforts prove unavailing, the pupillary opening, as some- times happens, is lost forever. In the previous description of disorder, no mention has been made of the cartilago nictitans, or haw, or third eyelid, as it has been called. This tliin body is very active, and resides at the inner corner of the eye; of course, in a disease under which the eye is pained by light, the haw is protruded to the utmost. In ophthalmia, however, it is covered by an inflamed membrane, and though in health its movements are so rapid that it may easily escape notice, yet in this disease it lies before TEEMINATION TO SPECIFIC OPH- THALMIA. SPECIFIC OPHTHALMIA. 53 the eye, red and swollen ; this substance it was once common for farriers to excise, under a foolish notion of removing the cause of the disorder. The use of the cartilago nictitans in the healthy eye will now be explained. Let the reader inspect any of the illustrations to this article ; he will find the outer corner represented as being much higher than the inner corner of the eye, where the active little body resides. Under the upper lid, near to the outer corner, is situated the lachrymal gland, which secretes the water or tears of the eye. Suppose any substance "gets into the eye;" being between two layers of conjunctiva, it creates much anguish, it provokes constant motion of the lid, which in its turn causes the lachrymal gland to pour forth its secretion. Liquid flowing over a smooth globe of course gravitates ; the substance "in the eye" is thus partly washed and partly pushed toward the inner corner. Now, the base of the cartilago nictitans rests upon the fat at the back of the eye. Pain causes the globe to be retracted by spasmodic jerks; adipose matter cannot be compressed, and it is therefore driven forward every time the muscles act. The fat carries with it the cartilago nictitans, and the edge of the body being very fine and lying close to the globe, shovels up any foreign substance that may be within its reach, to place it upon the rounded development at the inner corner of the eye. Still may the reader inquire, if the cartilago nictitans is covered with con- junctival membrane, and the inner corner of the eye is enveloped in the same, does not the foreign substance occasion pain to these as it did to the globe of the eye ? No ; it was just hinted that conjunctiva is not sensitive except two layers of the membrane are together, as the ball and the inner surface of the eyelid. The haw, therefore, has no sensa- tion upon its external surface, neither has the inner corner of the eye, whence all foreign bodies are quickly washed by the overflow of tears. Farriei's, however, are not an extinct race ; many of the fraternity still exist, still practice, and are, it is to be feared, very little improved. Should one of these gentlemen offer to cure specific ophthalmia, it is hoped the owner, after the foregoing explanation, will not allow the "haw" to be excised. Let every man treat the animals over which he is given authority with kindness, as temporary visitors with himself upon earth, and fellow- inhabitants of a striving world. Let him look around him ; behold the owner of a coveted and highly-prized racer to-day, in a week reduced to the possessor of a blind and wretched jade; then ask himself what kind of property that is to boast of, which may be deteriorated or taken from hira without his sanction ? Having answered that question, let him inquire whether it is better to propitiate the higher being by showing 54 CATARACT. tenderness toward his creatures, or to defy the power which can in an instant snatch away his possessions. CATARACT. Cataract is a white spot within the pupillary opening. The spot may he indistinct or conspicuous, — soft, undefined or determined ; it may be as small as the point of a needle, or so big as to fill the entire space : in short, any in- dication of whiteness or opacity upon the pupil is regarded as a cataract. Cataracts are designated according to the parts on which they reside. The lens of the eye is contained within a capsule, as an egg is within its shell. Any whiteness upon this PARTIAL CATARACTS, OR SMALL WHITE capsulc Is tcrmcd a capsulap cataract. The SPECK WITHIN THE PUPIL OF THE EVE. ^ . , . i i . lens floats in a nquor which surrounds it, as the white does the yolk of an egg. Any turbidness in this fluid is termed a milky cataract; any speck upon the lens is a lenticular cataract ; and any little glistening appearance behind the capsule is spoken of as a spurious cataract. Moreover, there are the osseous, the cartilaginous, and the opaque cataracts; but those distinctions rather concern the anatomist than the pathologist, as they may be guessed at, yet are not to be distinguished with certainty one from another, during life. That which more concerns the reader is, to learn the manner, if possi- ble, of preventing cataract from disfiguring his horse's eyes. Then will the gentleman be kind enough to hold a sheet of white paper close to his nose, so that the eyes may see nothing else, for a single half hour. Let us suppose the trial has been made. With many people the head has become dizzy and the sight indistinct. In some persons singing noises are heard and a sensation of sickness has been created. Let the author strive to explain this fact. Travelers, passing over the Alps, wear green veils, to prevent the strain or excitement which looking upon a mass of white snow occasions the visual organs. Any excitement is preju- dicial to the eye. Workers at trades dealing in minute objects, often go blind, and the use of the miscroscope has frequently to be discontinued. But to look continuously upon a white mass is the most harmful of all other causes. This fact must be considered as established. And what does the horse proprietor have done to his stable ? He orders the interior to be whitewashed. It looks so clean, he delights to see it ; but do the horses — does nature equally enjoy to look upon those walls of " spot- CATARACT. 55 less purity ?" Before those walls, with its head tied to the manger, stands the animal through the hours of the day. Close to its nose shines the painful whiteness which the master so enjoys. Is it, then, sur- prising (seeing how nature for its own wise purposes has connected all life) that the equine eye, doomed to perpetual excitement, sometimes shows disease ? A horse with imperfect vision is a dangerous animal. A small speck upon the lens confuses" the sight as much as a comparatively large mark upon the cornea. To render this clear, let the reader hold a pen close to the eye ; it prevents more vision than yonder huge post obstructs. So impediments are important, as they near the optic nerve. The lens is nearer than the cornea, and therefore any opacity upon the first structure is more to be dreaded. However, let it be imagined a horse, with an opacity upon the pupil, and the sight confused by staring at a white flat mass spread out before it, is led forth for its master's use. By the aid of the groom and its own recollections, it manages to tread the gangway, and even to reach the well-known house door in safety. The owner, an aged gentleman, of the highest respectability, comes forth in riding costume. He mounts, and throwing the reins upon the neck of the animal, sets his nag into walking motion, while he, erect and stately, looks about him and proceeds to pull on his gloves. The horse, however, has not gone many steps before the cataract and the confused vision, acting conjointly, produce alarm. The steed shies and the gentleman loses his seat, being very nearly off. The passengers laugh, the proprietor suffers in his temper, but the whip is used, and the equestrian is soon out of sight. The man and horse proceed some distance ; the gentleman becomes much more calm, and the horse recovers sufficient composure to try and look around it. The pace now is rather brisk, when the horse thinks, or its disabled vision causes it to imagine, it sees some frightful object in the distance. The timid animal suddenly wheels round. The rider is not prepared for the eccentric motion : he is shot out of the saddle. He falls upon his head; he is picked up and carried home; but afterward he avoids the saddle. Never buy the horse with imperfect vision ; never have the interior of your stable whitewashed. Then what color is to be employed ? Probably blue would absorb too many of the rays of light ; at all events, it seems preferable to copy nature. Green is the livery of the fields. In these the eyes take no injury, although the horse's head be bent toward the grass for the greater number of the hours. Consequently, the writer rec- ommends that green wash, which is cheap enough, should be employed, instead of the obnoxious white, for the interior of stables. 56 CATARACT. COMPLETE CATARACT. For complete cataract nothing can be done. In man, operation or couching may be performed with success ; but the horse can retract the eye and protrude the cartilago nictitans. Thereby difficulties are created ; but these may be overcome. However, when an open- ing through the cornea is perfected, the spasmodic contraction of the muscles of the eye, acting upon the fibrous covering of the globe, is apt to drive forth the liquid contents of the organ in a jet : this is ir- reparable, of course. When so fearful a catastrophe does not ensue, still the capsule of the lens is always difficult to divide, and the lens itself cannot easily be broken down. The lens, therefore, must be abstracted ; but that necessitates a large incision, which the previously named probability forbids. Displacement is the only resort left ; but the lens, when forced from its situation into the posterior or dark cavity, is, by the contraction of the muscles, forced up again. The uncertainty of the result, even when the operation is successfully performed, is peculiarly disheartening. Half lose their eyes in consequence of the attempt ; half the remainder are in no way benefited ; to the rest, as these cannot wear spectacles to supply the place of the absent lens, of course the pain endured becomes useless torture. Where pai'tial cataract is feared but cannot be detected, then arti- ficially dilate the pupil. Rub down two drachms of the extract of belladonna in one ounce of water. Have this applied, with friction, to the exterior of the lids and about the eye ; mind none gets into the eye. The belladonna, acted upon by the secre- tions, turns to grit; inflammation is the conse- quence, and the clearness of the cornea is im- paired. When the belladonna is properly used, it dilates the iris and exposes the margin of the lens, thus enabling the practitioner to inspect the eye in a full light. To tell a spurious cataract, which defect is never permanent, first observe the spot. Note if it present any metallic appearance, and try whether, as the horse's head is moved, it alters in shape, catching irregular lights. Then inspect the exterior of the eye ; see if it retain any signs of recent injury. Subsequently endeavor, so far as may be possible, DIAGRAM ILLUSTRATING THE ACTION OF BELLADONNA. The inner space represents the natural pupil, on which no cataract is to be observed. The second space represents the pupillary opening as it may be enlarged by the appli- cation of belladonna, whereon two partial cataracts are to be remarked. The other space merely represents the dilated pupil. FUNGOID GROWTHS. 57 to ascertain the exact position occupied by the defect: upon all this evidence put together, make up your opinion. To distinguish between the different kinds of cataract, apply the bella- donna. Next place the horse near a window or under a door. Should the sun shine, have the animal led into the full glare of day. Look steadily into the eye from different points of view. Then have the horse's head moved about, all the time keeping your sight fixed upon the part you are desirous of inspecting. Should one spot continue in every position, of one bulk, and of one aspect, never becoming very narrow and always occupying one place throughout the examination, — it is a lenticular cataract that is beheld. If the whiteness changes appearances, in some positions seeming very thin or perceptibly less bulky, it is assuredly a capsular cataract which is inspected. Most cataracts may either be partial or com- plete ; but a spurious cataract is always partial, never permanent, and invariably caused by vio- lence. For spurious cataract, treat the injury to the exterior of the eye. For other cataracts, do nothing: there is no known medicine of any beneficial effect. However, it is well to add, the author's and the gen- eral opinion favors the absorption of cataract ; or that these opacities may appear and after a time go away without the aid of medicine. Nevertheless, to hasten such a process, have the interior of the stable colored. However much in favor a clean white wall may be with grooms or with the lower order, exercise an informed judgment ; have the wall shaded of the tint most pleasant to the inhabitants' sight, and the prospect of recovery will by so trivial an outlay be materially facilitated. DIAGRAM ILLUSTRATING THE DIF- FERENT KINDS OF CATARACT. 1. A capsular cataract or an opacity, situated on the envel- ope of the lens. 2. A lenticular cataract or an opacity, within the substance of the lena. 3. A spurious cataract, or a particle of lymph adhering to the inner surface of the lenti- cular capsule. FUNGOID TUMORS WITHIN THE SUBSTANCE OF THE EYE. These, fortunately, are rare affections. We know of no immediate cause for their production. No man can prophesy their appearance. The horse, to human judgment, may enjoy the top of health ; may be in flesh and full of spirit — altogether blooming. Nevertheless, the action of the legs may perceptibly grow higher, and the ears become more active. The animal will wait to be urged or guided, when the road is 58 FUNGOID GROWTHS. clear. Also, it may run into obstacles, when the rider does not touch the rein. Should anything be left in the gangway of the stable, it is certain to be upset, by what the groom terms "that clumsy horse." Sometimes it will stand for hours together neglecting its food, with the head held piteously on one side. Occasionally, when at grass, it may be found separated from its companions, alone and dejected, with the head as before, held on one side, while the waters of the eye copi- ously bedew the cheek. FUNOUS H.EMAT0IDE8, OR CANCEROnS '' GROWTHS WITHIN THE SUBSTANCE At last thc cycs QXQ cxamincd. The eye- op THE EYE. "^ •' ball may be clear, but some brilliant yellow substance may be discerned shooting from the base of the interior, and the horse is declared contaminated by a cancerous disease. All is now explained : the sight is lost ; the horse is blind. There are three terrible decisions now left to the master. Is the life to be shortened? The thought shudders at taking existence, when misery pleads for consolation. Is the animal to live on and nurture to maturity the seeds of a cancerous disease ? The mind shrinks from subjecting any creature to the terrible depression and hopeless agony attendant upon such disorders. Is an operation to be performed ? Shall the surgeon extirpate the eye ? This last proposal seems the worst of all ; nor does inquiry improve the prospect. The cancer does not entirely reside within the eye ; it is not limited to that part. The taint is in the constitution, and the operation can do no more than retard its effect. The eye re- moved, the cancerous growth will soon fill the vacant orbit After two or several months of dreadful suspense, the life at last will be exacted, and the animal, worn out with suffering, will expire. Under such circumstances, the writer recommends death, before the full violence of the disease is endured. Should, however, the reader think differently, and prefer the extirpation of the eyeball, the operation will here be described. First, mind the operator has two knives not generally kept by veterinary surgeons : one of small size and slightly bent to one side; the other larger, and curved to one side till it has nearly reached a semicircle. Mind the operator has everything ready before he begin : a sharp scalpel, two straight triangular-pointed needles, each armed with strong twine ; one curved needle, similarly provided ; sponge, water, injecting tube, bellows, lint, — and all things at hand. It is necessary the proprietor should see to this, as some men will commence an operation upon a mere horse and be obliged to stop in the middle, not having brought all the instruments which they may require. FUNGOID GROWTHS. 59 Cast the horse. Impale both eyelids, each with one of the straight needles, and leave the assistant to tie the thread into loops. Through these loops the assistant places the fore-finger of each hand, and then looks toward his superior. The sign being given, the man pulls the eyelid asunder, while the surgeon rapidly grasps the straight knife and describes a circle round the globe, thereby sundering the conjunctival membrane. The knife is then changed, the small curved blade being taken. The assistant again makes traction, and the knife, being passed through the divided conjunctiva, is carried round the eyeball, close to the bone ; the levator and depressor muscles are detached by this movement. The assistant again relaxes his hold ; the operator relinquishing the knife, selects the curved needle. With this the cornea is transfixed. The thread is drawn through and is then looped. Into this loop the surgeon puts the fore-finger of his left hand, and giving the sign once more to his assistant, takes hold of the large bladed knife. Traction is made on all the loops. The curved knife is inserted into the orbit, and, with a sawing motion, is passed round the organ. The posterior structures are thereby divided, and the eye is drawn forth. The operation ought to be over in less time than five minutes ; but speed depends on previous prepara- tion. The assistant, during the operation, should rest his hand upon the horse's jaw and face ; sad accidents by that means are prevented ; but, above all things, he should be cool, doing just what is sufficient and no more. Some hemorrhage follows the removal of the orb; to stop it, inject cold water into the empty socket; should that have no effect, drive a current of air from the bellows upon the divided parts ; if this be of no avail, softly plug the cavity with lint, bandage the wound to keep in the dressing, and leave the issue to nature. Such is the undisguised operation for extirpating the horse's eye. The reader is confidently asked, whether a few months of miserable existence, with the certainty of a fearful death, are not dearly purchased at so great a suffering ? EXTIRPATIOJf OF THE EYE. 60 LACERATED EYELID. LACERATED EYELID. Horses frequently endeavor to amuse the weary hours by a playful game with one another ; if accident results, it is not wholly the fault of the guileless animals; they are tied to the mangers; they cannot exert their activity ; otherwise their principal enjoyment resides in the free- dom of their heels. And looking at a blank mass of monotonous white for many hours may have disabled the sight or have confused the judgment. The groom being absent, advantage is taken of the event to have a romp. The animals snap at one another over the divisions to their stalls; often the amusement extends, and four or five heads may be be- held united in the sport. Generally, however, the game is confined to two players; but, either way, no injury is meant; the teeth rattle, but they are intended to close upon empty space. However, man has to bear the consequences which his errors provoke. That species of con- finement to which hoi"ses are subjected renders the judgment uncertain and the sight untrue. The animal pretends to snap, but, either from one head not being removed quick enough or from the other head being protruded too far, the teeth catch the eyelid and divide it through the center. The injury is not very serious, for had malice impelled the assault, much more than an eyelid would have been grasped between the jaws. In other cases, the groom has driven nails into the wall of the gang- way ; grooms are fond of seeing the stable decora- ted with pendant objects of various kinds. So long as the nails are occupied, little danger ensues; but they are apt to be left vacant, and horses are con- stantly passing along the gangway. To leave room for the servant obliges the animal, very often, to keep close to the wall ; the projecting nail catches the lid of the eye, and a long rent, commencing upon EYELID TORN BT A NAIL. ""
