The treatment will depend upon the bone which is broken, and whother the fracture is simple or compound. In most cases of the latter description none will avail, and the horse had better be destroyed; but if the owner is averse to this, it will be on the whole the best surgery, though apparently not very scientific, to encase the parts with adhesive plasters and tow, and then treat it as a simple fracture. IF THE BONES OF THE SKULL are fractured, unless there are symptoms of pressure on the brain, it is advisable to leave all to nature, simply keeping the patient quiet and low, and if in a high state of plethora, bleeding and physicking. A BROKEN LOWER JAW is by no means uncommon as the result of a kick. The best treatment is to set the fracture, and then mould some gutta percha to it, which may be confined behind by strips round the forehead and poll, and before by a padded strap passed through the mouth. between the nippers and tushes, and beneath the tongue. The horse must be fed upon mashes and steamed food. IN FRACTURES OF THE SPINE AND PELVIS nothing can be done beyond rest and lowering, if necessary, by bleeding and physic. BroKEN RIBS, when they cause inflammation of the lungs or liver by their sharp ends pressing upon these organs, may be treated by buckling two or three ordinary rollers abreast of one another tightly round the chest, so as to prevent the natural dila- tation of the thorax, which takes place in inspiration, and which keeps up the irritation by constantly moving the ends of the ribs. The general means necessary to adopt to relieve the internal mis- chief will depend upon its extent. WHEN EITHER THE SCAPULA, HUMERUS, OR FEMUR is broken, all that can be done is to sling the horse, and by bandages endeavor to bring the limb into as natural a position as possible, and keep it there. There must of necessity be great displacement of the ends of the bones, and these cannot by any means be brought into appo- sition; but the sides in contact with one another, as they over- ride, will unite in course of time, and this is all that can be achieved by the utmost efforts of the veterinary surgeon. Fractures of the lower part cf the tibia, of the radius, of the canna bones and the pasterns, if simple, must be treated by adjast- ing the ends (which is the chief difficulty, and will often require strong extension to be employed), and then adapting to the sides FRACTURES—DISEASES OF MUSCLES, ETC. rare of the bones splints of wood or gutta percha. If, by the aid of assistants, the parts can be brought into a good position, these may ve caretully adjusted to maintain it, and may be kept in place by tapes or straps fastened moderately tightly around them. It is uscless, however, to attempt a minute description of the means tc be employed, which can hardly be understood without a demon. stration. Many horses have recovered a fair use of tlie limb by the application of splints, without slinging, as they will take care to avoia resting on that foot in consequence of the pain it gives ; but under the care of an accomplished veterinary surgeon, slings will afford the best chance of recovery.

DISEASES OF MUSCLE, TENDON, AND LIGAMENT. MUSCLE is subject to simple atrophy, with or without fatty de- generation. The disease shows itself by a wasting away of the part, accompanied by a flabby feel to the touch. It should be treated by friction, gentle but regular work, and steel given inter- nally, one drachm of the sulphate of iron powdered being mixed with the corn twice a day. RHEUMATIC INFLAMMATION of a muscle or muscles is one of the most common of all the diseases to which the horse is subject. Most frequently it attacks the muscles of the shoulder, or of the loins, sometimes both those parts being involved at the same time. . When acute it receives the name of a chill, and is generally brought on by exposing the horse to a draught of air after work, or by im- mersing him in cold wat« up to fils belly, with a view either to refr esh” him, or when the groom is lazy, to save him the trouble of cleaning. The symptoms are lameness or inability to use the part, the horse, when forced to do so, giving expressions of severe pain. If the shoulder is affected, the foot is not pat to the ground, and when the leg is moved backwards and forwards by the hand, great > 28 THE HORSE. p..n is evidently experienced. In severe cases there is fever with accelerated pulse (70 to 80), accompanied often by profuse sweat- ing, and heaving at the flanks, the legs remaining warm. After a short time the part swells, and is excessively tender. The treats ment should be by a copious bleeding, if the horse is of a mode- rately strong constitution; indeed, in severe cases it should be carried on till the pulse is greatly reduced, and repeated the neat day, if it returns to its original hardness and fulness. The bowels should be acted on as soon as it is safe to do so, and if the dung is very hard, backraking and clysters should be used, to accelerace the action of the medicine. The best aperient is castor oil, of which a pint may be given with an ounce of sweet spirits of nitre. When this has acted, if the kidneys are not doing their duty, a quarter of an ounce of nitre and a drachm of camphor may be made into a ball and given twice a day. CHRONIC RHEUMATISM of the muscles is similar in its nature to the acute form, but, as its name implies, it is more lasting, and of less severity. It often flies from one part to another, attacking the ligaments and tendons, as well as the muscular fibres. It is seldom much under control, and attention should be paid rather to improve the general health than to subdue the local affection. SMALL TUMORS, of about the size of a pea, often form upon the tendons, espevially the “‘ back sinews”’ of the fore legs. They may or may not occasion lameness, but they are always to be regarded with suspicion. As long as they remain indolent, they are better left alone; but when they produce inflammation and pain, the best remedy is the biniodide of mercury ointment, described at page 300. DISEASES OF CARTILAGE AND SYNOVIAL MEMBRANE. CARTILAGE is subject chiefly to ulceration. When this occurs, its cells become enlarged and crowded with corpuscles, which burst and discharge their contents; the intercellular structure at the same tine splits into bands, which, together with the corpuscles, form a fibro-nucleated membrane on the face of the cartilage. In old horses, the ulcerated cartilage covering the tibial surface of the astragalus is sometimes converted into a soft fibrous substance, abich ultimately assumes the appearance of hard and dense bone, commonly known as “ porcellaneous or ivory deposit.” It is ac- companied by no symptoms of inflammation; the sole evidence of disease, during life, being a stiffness of the joint, and a peculiar grating or crackling noise during all attempts at movement. When caries of the head of a bone has caused a loss of substance, the cartilage dies, and is gradually broken down by decomposition : but this cannot be said to be a disease of the cartilage itself. With the exception of navicular disease (which will be included under DISEASES OF CARTILAGE AND SYNOVIAL MEMBRANE, 29 the diseases of the foot), ulceration of cartilage is not very com- mon in the horse. ACUTE INFLAMMATION OF THE SYNOVIAL MEMBRANE Is seldom met with; but a chronic state, inducing an excessive secretion of pynovia, is extremely common. ‘The most usual situation is at the hock, where the swelling has received the name of pog-s -spavin and thoroughpin ; but they “also occur at the fetlock and knee joints ; in the former case being sometimes confounded with windgalls, which are inflamed bursa mucose. Bou-sPAVIN is very apt to attack young horses, when they are over-worked, before being fully seasoned; but it may occur at all ages. It shows itself at the inner side of the joint, because here the ligaments are wider apart, and there is more room for disten- sion. Its seat is the capsule between the tibia and astragalus, which is here unprotected by any strong fibrous covering, and readily yields to the gradual pressure of the secrction from its in- ternal surface. THOROUGHPIN may be either an increased secretion of the syno- vial capsule, between the astragalus and os calcis, or between the scaphoid and cuneiform bones, or of the bursa mucosa lying be- tween the tendo Achillis and the tendo perforatus. — In the first of these cases, it often coexists with bog-spavin, and the synovia may be made to fluctuate from one bag to the other, the only line of demarcation being the astragalo- calcanean ligament. Both bog-spavin and thoroughpin may exist, or either separately, without occasioning lameness; but where they are just established, there is generally some small degree of active inflammation, which causes a slight lameness on first going out of the stable, but soon disappearing. Lhe treatment should be by pressure, kept up for a long time, by means of a carefully-adjusted truss, alternated with cold affu- sion, and the use afterwards of tincture of arnica, diluted with water, as a wash. Subcutaneous scarification has succeeded in some few cases in causing the secretion to cease; but it has so often produced extensive inflammation of the joint, that the opera- tion is by no means to be recommended. Blistering with biniodide of mercury has also occasionally answered ; but no plan is so sue- cessful, on the whole, as pressure, alternating with cold affusion DELICATE YOUNG FOALS are subject to a rheumatic inflammia- tion of their synovial membranes, specially displayed in the knees and hocks, and apparently caused by exposure to cold. It seldoin goes on to produce disorganization of the cartilages, but the capsu- lar ligaments are distended with thin yellow synovia, causing considerable stiffness. The cellular tissue around the joints also becomes cedematous, and the legs fill all the way down io the feet. It is commonly known among ‘breeders as the joint evil,” and 30 THE HORSE. though in itself it is not dangerous, yet it marks the existence of constitutional weakness which is likely to occasion some more fatal malady. The ¢reatment should consist in attending to the geucral health by strengthening the mare, which is best ‘done by , giving her a drachm of the sulphate of iron in her corn twice a day. The joints of the foal should be rubbed with equal. parts of soap liniment, and spirit of turpentine, and it should be assisted to stand for the purpose of sucking at regular short intervals if unable to help itself. In aggravated cases, however, the foal is not likely to recover its general strength, and it may be better to destroy it, but so long’as it can stand and feeds well hopes may be entcr- tained of the joints recovering. INFLAMED TENDINOUS SHEATHS. EVERY PRACTICAL HORSEMAN is aware that the sheaths in which the back sinews and other tendons are lodged are liable to inflammation and thickening, without the tendon itself being involved. By passing the hand down the leg, an irregular network may be felt surrounding the tendons, which move up and down without disturbing it; and the surrounding cellular membrane is ulso thickened, and becomes hard and unyielding. There may be considerable heat about the part, but often it is quite cool; and the disease may continue for months without any great lameness, and with nothing to draw attention to it (excepting a slight stiffness on leaving the stable) but the sensation communicated to the hand. At length, an unusually severe day’s work sets up active inflammation, the Jeg rapidly fills, and there is so much lameness as to cause the horse to be thrown by.—The treatment in the early stage, should be the use of bandages, constantly kept wet with arnica and water, and nothing but walking exercise. After the thickening is fully established, no remedy short of blistering, or a charge, will be of the slightest avail, with a rest of two or three inonths. INFLAMED BURS/E MUCOSA. THESE SYNOVIAL BAGS are liable to inflammation, either from hard work, as in windgalls and thoroughpin, or from blows, as in gapped hock and elbow. The latter are said by some veterina- rians to be serous abscesses; but there is no doubt that in all horses a subcutaneous bursa exists on the cap of the elbow and hock; and these become inflamed and filled with a very thin synovia, when they are bruised. They never extend beyond a certain size, and have no tendency to burst; nor are they inclined toa healthy termination of their own accurd, but go on in the same conditicn from vear to year. WENDGALLS, OR PUFFS, are the most usual forms of these en- e INFLAMED BURSZ MUCOSA, at iaryements, and may be observed in the legs (hind as well as fore) of nearly every hard-worked horse, after a time. Great care in the management of the legs by bandaging will sometimes keep them off, and some horses have naturally no tendency to form them ; but in most cases, On examining the legs, just above the fetlock joints, of horses at work, a little oval bag may be felt on each side, between the back-sinew and the bone. If recent, it is soft and puffy; but if the work is hard, and the windgall is of long standing, it will be as tense asa drum. The synovial bag has no communication with the fetlock joint; but there is another sac in frent of the joint, and beneath the tendons of the extensors, which is often enlarged, though not so much so as the seat of the true windgall, and which is generally, though not always, continuous wich the synovial capsule of the joint.—The treatment consists in pressure by means of bandages, and the application of cold lotions, if the less are hot and inflamed. Blistering and rest will remove them entirely ; but no sooner is the horse put to work again, than they return as badly as ever. There is no radical cure but subcu- taneous puncture and searification, and this will produce too much adhesion to be advantageously applied. THE FORM OF THOROUGHPIN in which the bursa mucosa be- tween the tendo Achillis and the tendo perforatus is inflamed and - filled with synovia, has been alluded to at page 313, and its ¢treat- ment is there described. CAPPED HOCK is often the result of a bruise of the superficial bursa, which is situated on the point of the hock, immediately bencath the skin. It indicates either that the possessor has kicked in the stable or in harness; but it is more frequently caused in the former way than in the latter. The swelling is sometimes slicht, being then just sufficient to show the point slightly enlarged, and to give a soft, puffy sensation to the fingers, where there ought to be nothing but bone felt beneath the skin. The bursa always rolls freely on the bone, and when large, it can be laid hold of and shaken like a bladder of water.—The treatment should be directed to abate any slight inflammation that may exist, if the case is established ; but in recent ones, it is doubly necessary to apply cold fotions, which, however, there is some diffeulty in doing, owing to the prominent nature of the part. Ee eceeed- mt 3 pints. Mix. CAPPED ELBOW is precisely similar in its nature to capred hock, and must be treated in the same way. It is also known by the name of capulet. OF STRAINS. THE FIBRES OF MUSCLES, LIGAMENTS, AND TENDONS, AND THE FASCIA covering them, are all liable to be overstretched, and more or less mechanically injured. This is called a strain, the symptoms of which are similar to the inflammation of the part occurring ideopathically. They are heat, swelling, and pain on pressure or movement, shown by flinching in the one case, and lameness in the other. In some cases there is considerable effusion of blood or serum, the former occurring chiefly in the muscles, and the latter among the torn fibres of the tendons or ligaments. The symptoms and treatment will depend upon the part injured, which will be found described under the following heads; but in most cases an embrocation composed of equal parts of laudanum, olive oil, spirit of turpentine, and hartshorn, will be beneficial if applied after the first active inflammation has subsided. STRAIN OF THE BACK AND LOINS. WHEN A YOUNG HORSE has been hunted or ridden with hounds over any kind of fence, he is very apt to over-exert himself in his awkward attempts to clear the obstacle, and next day he will often show a stiffness of the loins and back, which is seated in the large muscles connecting the pelvis with the thorax. He is said to have ‘“‘ricked his back,” in the language of the stable, and if the mis- chief is confined to the muscles alone, he may generally be per- manently cured, though he will be more liable to a return than an auimal which has never suffered from any accident of the kind. if, however, the spinal cord is injured, either from fracture of tha vertebrae, or from effusion of blood or serum pressing upon it, the case is different, and a perfect cure is seldom obtained. It is, Lowever, very difficult to form a correct diagnosis between the one vase and the other, and the treatment may generally be conducted ‘with the hope that the more important organ is uninjured. When there is complete palsy of the hind extremities, so that the horse can neither feel nor use them in the slightest degree, the case is hopeless. For the management of the strain of the loins, a full bleeding should be adopted, as it generally happens that the horse STRAINS, 33 is plethoric and full of corn. Then apply a double fold ot thick funnel or serge, dipped in warm water, to the whole surface of the loins, cover this over with a layer of indiarubber shecting, and let it remain on, taking care to renew the water if it has become dry. It generally produces a copious sweating from the part, followed by a slight irritation of the skin, both of which afford relief. Iw three or four days the flannel may be removed, and the embroca tion alluded to above rubbed in two or three times a day, which will generally relieve the muscles so much that at the end of a week or ten days the horse is able to move quietly alout in a loose box, and the cure may be left to time, aided by a charge cn the back. STRAIN OF THE SHOULDER. SHOULDER STRAIN was formerly very often chosen as the seat of lameness in the fore extremity, solely because the case is so ob- scure that it is beyond the knowledge of the unskilful examiner. Nevertheless, it is by no means so uncommon as is supposed by some writers, and perhaps it may be asserted that it is now more frequently passed over when it really exists, than the reverse. It generally is seated in the serratus magnus, or pectoralis transversus muscles, but it may also occur in the triceps, or, indeed, in almost any of the muscles around the shoulder joint. The symptoms are very peculiar, and cannot well be mistaken by a careful observer who has once seen a case of shoulder lameness. In all other kinds (except the knee), the limb is freely moved while in the air, and no pain is expressed until the foot is about to touch the ground; but here the lameness is greatest while the knee is being protruded, and the limb is slung forward sideways, in a circular manner, which gives an expression of great imbecility. It also occasions great pain when the foot is lifted and drawn forward by the hand, just as in rheumatism of the part (already described at page 312). When the serratus magnus has been strained by a fall from a drop leap, or the pectoralis transversus by a slip, causing the legs to be widely separated, there is often great obscurity in the case; but the history of the accident will generally assist in forming a cor- rect diagnosis. The treatmené in the early stage will consist in bleeding from the plate vein, to the extent of five or six quarts of blood, followed by fomentations with hot water, if there is much heat and swelling, and giving a dose of physic as soon as the bowels will bear it. When the heat has disappeared, or at once, if there is none, apply the embrocation described at page 315; and if this does not produce relief, add to it one quarter of its bulk of tincture of cantharides. STRAINS OF THE KNEE. THE KNEE, unlike its analogue in the human subject (the wrist} 3 21) THE HORSE. is seldom strained in the horse, in consequence? of the strong liga ments which bind the bones of the carpus together. Still it some- times happens that the internal lateral ligaments are overstretched, or, in calf-kneed horses, the posterior common ligaments, or that connecting the scaphoid with the pisiform bone, or probably all these will suffer from over-extension. The accident may be re- cognised by the heat and swelling of the part affected, as well as by the pain given on using the joint. ‘The anterior ligaments are seldom strained, but are liable to injury from blows received in various ways. The treatment should be conducted on the same principles as those of strains in the shoulder. Cold applications will seldom do anything but harm in the early stage; but after hot fomentations have relieved the active mischief, by encouraging the effusion of scrum into the surrounding cellular membrare, the former may be used with advantage. When the heat and other signs of active inflammation have disappeared, the biniodide of mercury ointment may be rubbed in, avoiding the back of the joint. STRAIN OF THE FETLOCK. Tifs ACCIDENT shows itself at once, in consequence of the super- ficial nature wf the joint, by swelling, heat, soreness to the touch, and lameness. It may be very slight or very severe, but im the latter case it is generally complicated by strain of the back sinews, or suspensory ligament. The treatment will be precisely on the saine plan as for strain of the knee. When the anterior ligaments of the fetlock joint are strained and inflamed, as so often happens with race-horses, the condition is known as ‘‘shin sore.” STRAIN OF THE COFFIN JOINT. DISSECTION PROVES that this joint is sometimes the seat of strain; but it is almost impossible to ascertain its existence with certainty during life. The diagnosis is, however, not of much consequence, as the treatment will be the same, whether the coffin joint, or the navicular joint is the seat of the mischief. In any case, if severe, bleeding from the tue should be had recourse to, followed by cold applications around the coronet, by means of a strip of flannel or felt, tied loosely around the pastern, and kept constantly wet. Wher the heat has subsided the coronet should be blistered. STRAIN OF THE SUSPENSORY LIGAMENTS. THE SUSPENSORY LIGAMENT not being elastic like the back sinews (which, though not in themselves extensible, are the pro- longations of’ muscles which have that property), is very liable to strains, especially in the hunter, and to a less degree.in the race- horse. The accideut is readily made out, for there is local swelling STRAINS. 35 and tenderness, and in the well-bred horse, which is alone likely to meet with a strain of this kind, the leg is rarely suthciently gummy to prevent the finger from making out the condition of the ligaments and tendons. There is no giving away of the joints as in ‘ break-down,” but on the contrary the leg is flexed, and if the ease is a bad one, the toe only is allowed to touch the ground. In ordinary cases, however, there is merely slight swelling of the suspensory ligament in a limited spot usually near its bifurcation, or sometiimes in one division only close above the sesamoid bone to which it is attached. The horse can stand readily on that leg, but on being trotted he limps a good deal. Sometimes. however, there is a swelling of the feet without lameness, but in this case the enlargement is generally due to an effusion of serum into the ecilular covering of the ‘igamént, and not to an actual straix of its fibres.—The treatment will depend greatly upon the extent of the misehief; if there is no great injury done, and the enlargement is chiefly from effusion of serum, rest and cold applications by means of bandages or otherwise will in the course of two or three months effect a cure. Generally, however, the case will last six or eight months before the ligament recovers its tone; and in a valuable horse no attempt should be made to work him before that time. Where the swelling is small, as it generally is, bandages have no power over it, as the projection of the flexor tendons keeps the pressure off the injured part. Here, dipping the leg in a bucket of water every hour will be of far more service than a bandage, and the sudden shock of the cold water will be doubly efficacious. After all heat has disappeared the biniodide of mercury may be used as a blister two or three times, and then the horse may either be turned out, or put into a loose box for three or four months, after which walking exercise will complete the cure. STRAIN OF THE BACK SINEWS. IN THIS ACCIDENT the position of the leg is the same as in strain of the suspensory ligament, and there is no giving way of the joints. ‘The flexor tendons are enlarged, hot, and tender, and there is great lameness, the horse having the power to flex the joints below the knee, but resolutely objecting to extend them, by bearing what little weight is unavoidable upon his toe. The case is often confounded with a “break-down,”’ but it may readily be distin- guished by the fact that in the latter the joints give way on putting the weight upon them, whilst in mere strains they do not, and the tendency is to the cyposite extreme. Frequently after a bad strain of the flexor tendons, the fetlock is ‘“‘over shot,” or beyond the upright, in consequence of the continued flexion of the joint, to prevent pressure upon the injured fibres, and in the manage: ment this result should be carefully guarded against. The injury 36 THE HORSE. is generally confined to the sheath of the tendons, which in most cases gradually puts on an inflammatory condition for some time before actual lameness is observed. In bad eases, however, the ligamentous fibres which are given off by the posterior carpal ligament to the flesor tendons are ruptured, greatly increasing the amount of inflammation and subsequent loss of strength. In any ase the tendon feels spongy, and slightly enlarged, and there is more or less soreness on pressure and on being trotted, but in the latter case exercise removes the tenderness, and very often tempo- rarily causes an absorption of the effused fluid, which is again deposited during rest. ‘This state of things goes on for a time, the proom doing all in his power to alleviate it by wet bandages, Xc., but at last a severe race or gallop brings on an extra amount of inflammation, with or without actual strain of the fibres of the tendon, and then there can be no doubt about the propriety of rest and severe treatment. It often happens that both legs are slightly affected, but one being more tender than the other, the horse attempts to save it by changing legs, the consequence of which is that the comparatively sound tendons are strained, and he returns to his stable with both legs in a bad state, but with one of them requiring immediate attention.—The treatment should be by lucal bleeding (from the arm, thigh, or toe), followed at first by warm fomentations, and in a few days by cold lotions. A high- heeled shoe (called a patten) should be put on the foot, so as ta allow the horse to rest part of the weight upon the heel without distressing the tendon, and this will have a tendency to prevent him from over shooting at the fetlock joint, which he will other- wise be very apt to do from constantly balancing his leg on the toe. After three or four days the hot fomentations will have done what is wanted, and a cold lotion may be applied by means of' a loose linen bandage. The best is composed as follows :— Take of Muriate of Ammonia . ..... 20% Vinegar . brits We) i pint. Methylated Spirit of Wage iiietl leks ar (eee Wiatet fo lites 2 quarts. Mix. With this the bandage should ss ies cee wet, the applica- tion being continued for a fortnight at least, during which time the patient must be kept cool, by lowering his food, and giving hin. a dose of physic. At the end of three weeks or a month from the accident, the leg must be either blistered or fired. the choice depending upon the extent of injury, and the desire to avuid a blemish if such a feeling exists. The former is the more effica- cious plan no doubt, but blistering will frequently suffice in mild cases. If, however, the tendons at the end of a month continue ereatly enlarged, a cure can hardly be expected without the use of » the “irons.” BREAKING DOWN. at BREAKING DOWN. (GREAT CONFUSION exists among trainers as to the exact nature vf this accident, which is considered by the veterinary surgeon to consist in an actual rupture of the suspeusory ligament either nhove or below the sesamoid bones, which, in fact, merely separate this apparatus of suspension into two portions, just as the patella intervenes between the rectus femoris and the tibia. Whichever part of the suspensory apparatus is gone (whether the superior or inferior sesamoidal ligament is immaterial), the fetlock and pastern joints lose their whole inelastic support ; and the flexor tendons, toyvether with their ligamentous fibres which they receive from the carpus, giving way, as they must do, to allow of the accident taking place, the toe is turned up, and the fetlock joint bears upon the ground. This is a complete ‘‘ break down ;” but there are many cases in which the destruction of the ligamentous fibres is not complete, and the joint, though much lowered, does not actually touch the ground. These are still called breaks down, and must be regarded as such, and as quite distinct from strains of the flexor tendons. The accident generally occurs in a tired horse, when the flexor muscles do not continue to support the liga- ments, from which circumstance it so often happens in the last few strides of a race. Zhe symptoms are a partial or entire giving way of the fetlock joint downwards, so that the back of it either tcuches the ground, or nearly so, when the weight is thrown upon it. Usually, however, after the horse is pulled up, he hops on three legs, and refuses altogether to put that which is broken down to the ground. In a very few minutes the leg “ fills” at the seat of the accident, and becomes hot and very tender to the touch. There can, therefore, be no doubt as to the nature of the mischief, and the confusion to which allusion has been made is one of names rather than of facts. Treatment can only be directed to a partial recovery from this accident, for a horse broken down in the sense in which the term is here used can only be used for stud purposes or at slow farm work. A patten shoe should at once be put ou alter bleeding at the toe to a copious extent, and then fomenta- tions followed by cold lotions should be applied, as directed in the last section. As there must necessarily be a deformity of the leg, there can be no objection on that score to firing, and when the severe inflammation following the accident has subsided this opera- tion should be thoroughly performed, so as to afford relief not only by the counter irritation which is set up, and which lasts only for a time, but by the rigid and unyielding ease which it leaves behind for a series >f years. 21 38 THE HORSE STRAINS OF THE HIP JOINT, STIFLE, AND HOCK THE HIP JOINT, OR ROUND BONE, is liable to be strained by the hind feet slipping and being stretched apart, or by blows against the side of the stall, when cast, which are not sufficient to dislocate the femur, but strain its ligaments severely. The conse. quence is an inflammation of the joint, which is evidenced by a dropping of one hip in going, the weight being thrown more upon the sound side than upon the other. This is especially remarkable on first starting, the lameness soon going off in work, but return- ing after rest. The case, however, is a rare one, and its descrip- tion need not, therefore, occupy much of our space. When it does happen, it is very apt to lead to a wasting of the deep muscles of the haunch, which nothing but compulsory work will restore to a healthy condition. The-only treatment necessary in the early stage of strain of the hip joint is rest and cooling diet, &c.; but, after six weeks or two months, a gradual return to work is indis- pensable to effect a cure. STRAINS OF THE STIFLE. independently of blows, are rare; but the latter often are inflicted upon this joint in hunting, leaving little evidence externally, so that it is almost always “Gaebatal whether the injury is the result of a blow or strain. The symptoms are a swelling and tenderness of the joint, which can be ascer- tained by a careful examination ; and on trotting the horse, there is manifested a difficulty or stiffness in drawing forward the hind Icg under the belly. The treatment must be by bleeding and physicking in the early stage, together with hot fomentations to the part, continued every hour until the heat subsides. After a few days. if the joint is still painful, a large blister should be applied, or, what is still better, a seton should be inserted in the skin adjacent. THE HOCK ITSELF is liable to strain, independently of the pecu- jiar aceident known as “curb.” When it occurs, there is some heat oi the part, with more or less lameness, and neither spavin, thoroughpin, nor curb to account for them. The injury is seldom severe, and may be relieved by fumentations for a day or two, followed by cold lotions, as presented at page 320, for strain of the hack sinews. CURB. TILE LOWER PART OF TITE POSTERIOR SURFACE Of the os ealecis is firmly united to the cuboid and external metatarsal bone by twa strong ligamentous bands, called the calcaneo-cuboid and ealeanco- metatarsal ligaments. The centre of these ligaments is about seven or eight inches below the point of the hock, and when a soft but clastic swelling suddenly makes its appearance there, it may CURB. 39 with certainty be asserted that a ‘‘ curb” has been thrown out. The accident uvccurs somewhat suddenly; but the swelling and inflain- mation do not always show themselves until after a niyht’s rest when the part is generally enlarged, hot, and tender. The previse extent of the strain is of little consequence; for whatever its nature, the treatment should be sufficiently active to reduce the ligaments to their healthy condition. Some horses have naturally the head of the external small metatarsal bone unusually large, and the hock so formed that there is an angle between the large meta. tarsal bone and the tarsus, leaving a prominence, which, however, is hard and bony, and not soft and elastic, as is the case with carb. Such hocks are generally inclined to throw out curbs; but there are many exceptions, and some of the most suspicious-looking joints have been known to stand sound for years. Curbs are seldom thrown out by very old horses, and usually occur between the com- mencement of breaking-in and the seventh or eighth year, though they are not unfrequently met with in the younger colt, being occa- sioned by his gambols over hilly ground. The treatment should at first be studiously confined to a reduction of the inflammation ; any attempt to procure absorption till this is effected being inju- rious in the extreme. If there is much heat in the part. blood may be taken from the thigh vein, the corn should be removed, and a dose of physic given as soon as practicable. The curh should then be kept wet (by means of a bandage lightly applied) with the lotion recommended at page 316 for capped hocks, and this should be continued until the inflammation is entirely gone. During this treatment, in bad cases, a patten shoe should be kept on, so as to keep the hock as straight as possible, and thus take the strain off the ligaments which are affected. After the part has become cool, it may be reduced in size, by causing absorption to be set up; which is best effected by the application of mereury and iodine (both of which possess that power), in such a shape as to cause a blister of the skin. ‘The biniodide of mereurr has this double advantage, and there is no application known to surgery which will act equally well in effecting the absorption of a curb. It should be applicd in the mode recommended at page 300, and again rubbed on at an interval of about a week, for three or four tines in successisn, when it will generally be found that the ab- sorption of the unnatural swelling is effected; but the ligaments remain as weak as before, and nothing but exercise (not too severe, or it will inflame them again) will strengthen them sufficiently to prevent a return. Friction with the hand, aided by a slightly stimulating oil (such as neat’s-foot and turpentine mixed, or neat’s- {oot and oil of origanum, or, in fact, any stimulating essential oi)), will tend to strengthen the ligaments, by exciting their vessels te throw out additional fibres; and in course of time a curb may be 40 THE HORSE. considered to be sufficiently restored to render it tolerably safe te usc the horse again in the same way which originally produced it. DISLOCATION. By DIsLocaTION is meant the forcible removal of the end of a bone from the articulating surface which it naturally occupies. In the horse, from the strength of his ligaments, the accident is not common; those that do occur being “chiefly i in the hip joint, and in that between the patella and the end of the femur. DISLOCATION OF THE HIP JOINT is known by the rigidity of the hind leg, which cannot be moved in any direction, and is carried by the horse when he is compelled to attempt to alter his position. There is a flatness of the haunch below the hip, but the crest of the ilium is still there, and by this the accident may be diagnosed from fracture of that part. No treatment is of the slightest avail, as the part cannot be reduced, and the horse is useless except for stud purposes. The accident is not very common. DiSLOCATION OF THE PATELLA sometimes becomes habitual, occurring repeatedly in the same horse, apparently from a spas- modic contraction of the external vastus muscle, which draws the patella outwards, and out of the trochlea formed for it in the lower head of the femur. When the cramp goes off, the patella drops into its place again as soon as the horse moves, and no treatment is required. Occasionally, however, the dislocation is more complete, and nothing but manual dexterity will replace the bone in its proper situation. Great pain and uneasiness are expressed, and the operator must encircle the haunch with his arms and lay hold of the patella with both hands, while an assist- ant drags forward the toe, and thus relaxes the muscles which are inserted in it. By forcibly driving the patella into its place it may be lifted over the ridge which it has passed, and a snap annuunces the reduction. WOUNDS OF JOINTS. THE KNEE is the joint most frequently suffering from wound, being liable to be cut by a fall upon it, if the ground is reugh ; and if the accident takes place when the horse is going ata rapid pace, the skin, ligaments, and tendons may be worn through by friction against the plain surface of a smooth turnpike | road. Whother the joint itself is injured, or only the skin, the accident is called a “broken knee,’ and for convenience sake it will be well to consider both under the present head. WHEN A BROKEN KNEE consists merely in an abrasion of the skin, the attention of the groom is solely directed to the restora- tion of the hair, which will grow again az well as ever, if the WOUNDS OF JOINTS. 41 libs or roots are not injured. These are situated in the mternal layer of the true skin, and therefore, whenever there is a smooth red surface displayed, without any difference in the texture of its parts, a confident hope may be expressed that there will be no blemish. If the skin is penetrated, either the glistening surface of the tendons or ligaments is apparent, or there is a soft layer uf cellular membrane, generally containing a fatty cell or two in the middle of the wound of the skin. Even here, by proper treat ment, the injury may be repaired so fully, that the space uncovered by hair cannot be recognised by the ordinary observer, and not by any one without bending the knee and looking very carefully at it. The best treatment is to foment the knee well with warm water, so as to remove every particle of grit or dirt; go on with this every hour during the first day, and at night apply a bran poultice to the knee, which should be left on till the next morn- ing. Then cleanse the wound, and apply a little spermaceti oint- ment, or lard without salt, and with this keep the wound pliant until it heals, which if slight it will in a few days. If the skin is pierced there will generally be a growth above it of red flabby granulations, which should be carefully kept down to its own level (not beneath it), by the daily use of blue stone, or if neces- sary of nitrate of silver. As soon as the wound is perfectly healed, if the horse can be spared, the whole front of the knee and skin should be dressed with James’ blister, which will bring off the hair of the adjacent parts, and also encourage the growth of that injured by the fall. In about three weeks or a month from its application, the leg will pass muster, for there will be no difference in the color of the old and new hair as there would have been without the blister, and the new will also have come on more quickly and perfectly than it otherwise would. WHEN THE JOINT ITSELF is opened the case is much more serious, and there is a risk not only of a serious blemish, which can seldom be avoided, but of a permanent stiffness of the leg, tke mischief sometimes being sufficient to lead to constitutional fever, and the local inflammation going on to the destruction of the joint by anchylosis. The treatment should be directed to cleanse and then close the joint, the former object being carried out by a careful ablution with warm water, continued until there is no doubt of all the dirt and grit having been removed. Then, if there is only a very small opening in the capsular ligament, it may be closed by a careful and light touch of a pointed iron heated to a red heat. Generally, however, it is better to apply sume dry carded cotton to the wound, and a bandage over this, leaving all on for four or five days, when it may be removed and reapplied. ©The horse should be bled largely and physicked, taking care to prevent all chance of his lying down by racking him up 42 THE HORSE. He will seldom attempt to do this, on account of the pain occa - Sioned in bending the knee, but some animals will disregard this when tired, and will go down somehow. When the cotton is reapplied, if there are granulations above the level of the skin, they must be kept down as recommended in the last paragraph, and the subsequent treatment by blister may be exactly the same. By these means a very extensive wound of the knee may be often speedily cured, and the blemish will be comparatively trifling. THE KNEE IS SOMETIMES punctured by a thorn in hunting, causing great pain and lameness. If it can be felt externally, it is well t) cut down upon it and remove it; but groping in the dark with the knife among important tendons in front of the knee is not on any account to be attempted. The knee should be well fomented, five or six times a day, until the swelling, if there is any, subsides, and, in process of time, the thorn will either show its base, or it will gradually free itself from its attachments and lie beneath the skin, from which position it may be safely Ss with the knife.

General Remarks—Catarrh—Influenza or Distemper—Bronchitis — Chronic Cough— Laryngitis— Roaring, Whisthng, Etc.— Pneumonia and Congestion of the Lungs— Pleurisy — Pleuro- dynia—Phthisis—Broken Wind—Thich Wind—Spasm of the Diaphragm—Diseases of the Heart—Diseases of the Blood Ves- sels in the Chest and Nose. GENERAL REMARKS. ‘THE IMPORTANCE OF SOUNDNESS in the respiratory apparatus is so fully recognised, that in common parlance it is put before the organs of locomotion, a popular expression being “sound, wind and limb.” It is true that good wind is useless without legs: ; but the diseases of the latter are known to be more under control thag those of the chest, and hence it is, perhaps, that the wind is sc carefully scrutinized by all purchasers of horses. There is, also, much greater difficulty in ascertaining the condition of the lungs and their appendages, and the ordinary observer can only judge of them by an absolute trial; while the state of the legs may be seen and felt, and that of the feet can be tolerably well ascertained by a very short run upon hard ground. So, also, with the acute diseases of’ these parts; while the legs and feet manifest the CATARRH. 43 slightest inflammation going on in them by swelling and heat, the nir-passages may be undergoing slow but sure destruction, withort giving out any sign that can be detected by any one but the prac- tised veterinarian. In most of the diseases of the chest there is disturbance of the breathing, even during a state of rest; but in some of them, as in roaring, for instance, no such evidence is afforded, and the disease can only be detected by an examination during, or immediately after, a severe gallop. CATARRH, OR COLD. CATARRH may be considered under two points of view; either as an inflammation of the mucous membrane of the nasal cavities, accompanied by slight general fever; or as an ephemeral fever of three or four days duration, complicated with this condition of the nose. The latter is, perhaps, the more scientific definition, but for common purposes it is more convenient to consider it as mainly consisting in the most prominent symptom. There is invariably some degree of feverishness, sometimes very considerable, at others so slight as to be easily passed over. Usually the pulse is accele- rated to about forty or fifty, the appetite is impaired, and there is often sore throat, with more or less cough. On examining the interior of the nostrils, they are more red than natural, at first dry and swollen, then bedewed with a watery discharge ‘which soon becomes yellow, thick, and, in bad cases, purulent. The eyes are generally involved, their conjunctival coat being injected with blood, and often some slight weeping takes place, but there is always an expression of sleepiness or dulness, partly owing to the local condition of the organ, and partly to the general impairment of the health. The disease is caused in most instances by a chill. either in the stable or out, but sometimes, even in the mildest form, it appears to be epidemic. The treatment will greatly depend upon the severity of the seizure; usually, a bran-mash containing fron, six drachms to one ounce of powdered nitre in it, at night, for two or three consecutive periods, will suffice, together with the abstrae- tion of corn, and, if the bowels are confined, a mild dose of physiv should be given. In more severe cases, when there is cough and g ns iderable feverishness, a ball composed of the following i ingTre- dients may be given every night :— Take of Nitrate of Potass- . . . s « « « 2 drachms.

If the throat is sore, an embrocation of equal parts of oil, tur. pentine, tincture of cantharides, and hartshorn, may be rubbed in night and morning. 44 THE HORSE. chould the disease extend to the bronchial tubes, or sulistance of the lungs, the treatment for bronchitis or pneumonia must be adopted. The stable should be kept cool, taking care to make up for the difference in temperature by putting on an extra rug; water should be allowed ad libitum, and no corn should be given. Sometimes the discharge becomes chronic, and it is then known by the name ozena. INFLUENZA, OR DISTEMPER. THIS MAY BE CONSIDERED TO BE an epidemic catarrh, but the symptoms are generally more severe and leave greater prostration of strength behind them. They also require more careful treat- ment, which must be specially adapted to the attack, for remedies which will arrest the disease in one year will totally fail the next time that the-epidemic prevails. The fever of late years has had a tendency to put on the typhoid type, and bleeding, which for- merly was often beneficial, is now completely forbidden. The symp- foms are at first similar to those already described as pertaining to common catarrh, but after a few days the accompanying fever is more severe than usual, and does not abate at the customary period. The appetite is altogether lost, and the appearance of the patient is characteristic of severe disease rather than of a trifling cold. It is, however, chiefly from the fact that a number of horses are scized with similar symptoms, either at the same time or rapidly follow- ing one another, that the disease is recognised. It usually prevails in the spring of the year, or in a wet and unhealthy autumn. Sometimes almost every case runs on to. pneumonia, at others the bronchial mucous membrane alone is attacked ; but in all there is extreme debility in proportion to the apparent nature of the disease. The ordinary appearances exhibited in recent epidemics have been as follows :—The first thing observed is a general slight shivering, accompanied by a staring coat. The pulse is weak, and slightly accelerated, but not to any great extent; the mouth feels hot; the eyes and the nostrils are red; the belly is tucked up; there is no appetite; cough, to a varying extent, begins to show itself; and there is generally a heaving of the flanks. ‘The legs and feet are not cold as in pneumonia, but beyond this they afford no positive signs ‘The cellular membrane around the eyes, and of the legs, gencrally swells about the second day, and often the head and limbs become quite shapeless from this cause. In the early stave the bowels are often relaxed, but afterwards they are as frequently zonfined. Sore throat is a very common complication, but it is not by any means an invariable attendant on influenza. It is, however, INFLUENZA—BRONCHITIS. 45 somewhat difficult to ascertain its existence, as in any case there is no appetite for food. The treatment should be conducted on the principle uf husbanding the strength, and, unless urgent symptoms of inflammation show themselves, “the less that is dove the better, If tke trachea or larynx is involved only slightly, ¢ muter irrita- tion, by means of a liquid blister, must be tried, without resorting £0 strong internal medicines ; but if serious mischief ensu res, the cuse must, to a certain extent, be treated as it would be when soming on without the complication of influenza, always taking care to avoid bleeding, and merely acting on the bowels by gentle aperients, and on the skin and kidneys by the mildest diaphoretie and diuretic. The following is the ordinary plan of treatment adopted : Take of Spirit of Nitric Ether . ... . - 1 ounce.

By constantly offering to the horse thin gruel (taking care that it does not become sour), and no plain water, sufficient nourish- ment may be given, as his thirst will induce him to drink. During the stage of convalescence the greatest care must be taken. At first, as soon as the cough has somewhat subsided, a mild stomachie ball will be desirable, such as ‘Takeo. extract of Gentian... . ©. «.« 6 drachms. Powdered “Ginger ©. «.) 0's). 2 2 drachms. Mix: Afterwards, if the case goes on favorably, and the appetite returns, the restoration may be left to nature, giving the horse by degrees his usual allowance of corn, and adding to his morning and evening feed one drachm of sulphate of iron in fine powder. It must not be attempted to give this until the appetite is pretty keen, or the horse will be disgusted, and will probably refuse his corn altogether. Should typhoid symptoms be clearly established, the case must be treated according to the directions hereafter laid down fo: ty. hus fever. BRONCHITIS. BRONCHITIS is an inflammation of the mucous membrane lining (he bronchi, and almost invariably extending to these parts through the trachea, from the larynx and nasal passages, which are pri- marily affected as in ordinary cold. The membrane in the early stage becomes filled with blood, and as a consequence the diameter of the tubes is diminished, attended by some difficulty and in- ereased rapidity of breathing. After a time a frothy mucus is poured out from it, and this “still further interferes with respira- tion, and necessitates a constant cough to. get rid of it. These symptoms are always present, but they will vary greatly in inten- 46 THE HORSE, sity, and in the rapidity with which they progress, from which cir- cumstanves bronchitis ts said to be acute or chronic, as the case may be. ln the acute form there are also several variations, and veterinary writers are in the habit of again subdividing it into acute and sub-acute, but the two leading divisions are sufficient for a'i practical purposes. It begins with the usual premonitory appearances of a severe cold, accompanied by a staring: coat, and entire loss of appetite. The breathing is somewhat quicker than natural, and the pulse is raised to sixty or seventy. The legs re- main of the usual temperature, and there is a hard dry cough, the liming membrane of the nostrils being intensely red, and in severe cases dry and swollen. On auscultation there is a dry rattling sound, very different from the crepitation of pneumonia, and as soon as mucus is secreted, succeeded by gurgling, and soap-bubble sounds, easily distinguished when once heard. If the attack goes on favorably, the cough becomes loose, and there is a free dis- charge of mucus, both from the lungs, as evidenced from the nature of the cough, and from the nostrils, as shown by the run- ning from them. On the other hand, the prognosis is unfavorable when the breathing is very laborious, with the legs extended, and the cough constant and ineffectual in affording relief. Should no rclicf be afforded, death takes place a week or ten days after the onset of the disease, from suffocation. The treatment should de- pend greatly upon the urgency of the inflammation, which only an experienced eye can judge of. If slight, nitre and tartar emetic internally, and a blister (to one or both sides, according to the extent of bronchi involved), will suffice, but in very severe cases blood must be taken at the onset, or it will be impossible to control the inflammation. Bleeding should be avoided if it is judged prudent to do so, for of late years the type of diseases has changed so much in the horse, that he is found to bear loss of blood badly. Nevertheless, it is not wise to lay down the rule that it is never desirable. The bowels must be acted on by the ordinary physic ball, resorting to raking and clysters, if the time cannot be afforded for the usual laxative preparation. For the special control of the morbid state of the membrane the following ball will be found advantageous :— Take Ce Svurtquigs ie we Sos wm Ce yak =. a) area Calomel a ge RS eee cee ae See eer en Tartar Emetie og Ve esi oe 40 Se oOteeOrgraine, INGER O } yo Arey Sa Ga egies te Shes ote eee eS Mix with treacle, and give twice a day. Should the disease continue after the blister is healed, a large seton may be put in one or both sides with advantage. CHRONIC BRONCHITIS seldom exists except as a sequel to the acute form, and after adopting the balls recommended for that CHRONIC COUGH. 47 state, it may be treated by attention to the general health, a seton in th side, and the exhibition of an expectorant ball twice a day, zomposed of the following materials :— Take of Gam Ammoniacum . .°. - « « « #$ Ounce.

By Tr1s TERM is understood a cough that comes on without any fever or evidences of the horse having taken cold. It differs in this respect from chronic bronchitis, which generally supervenes upon the acute form, and is always attended in the early stage by feverishness. It appears probable that chronic cough is dependent upon an unnatural stimulus to the mucous membrane, for it almost always makes its appearance when much “orn is given without due preparation, and ceases on a return to green food. It is, therefore, very commonly termed a stomach cough. The symptoms are all summed up in the presence of a dry cough, which is seldom mani- fested while in the stable, but comes on whenever. the breathing is hastened by any pace beyond a walk. Two or three coughs are then given, and the horse perhaps is able to go on with his work, but after resting for a few minutes, and again starting, it comes on again, and annoys the rider or driver by its tantalizing promise of disappearance followed by disappointment. Very often this kind of cough is caused by the irritation of worms, but any kind of dis- order of the digestive organs appears to have the power of pro- ducing it. The usual treatment for chronic bronchitis seems here to be quite powerless, and the only plan of proceeding likely to be attended with success, is to look for the cause of the irritation, and remove it. Sometimes this will be found ina hot stable, the horse having previously been accustomed toa cool one. Here the altera- tion of the temperature by ten or fifteen degrees will in a few days effect a cure, and nothing else is required. Again, it may be that the corn has been overdone, in which case a gentle dose of physic, followed by a diminished allowance of corn, and a bran-mash twice a week, will be successful. If the stomach is much disordered, green food will be the best stimulus to a healthy condition, or in its absence a few warm cordial balls may be tried. The existences xf worms should be ascertained in doubtful cases, and if they are present, the proper remedies must be given for their removal. Linseed vil and spirit of turpentine, which are both excellent worm remedies, are highly recommended in chronic cough, and whether or not their good effect is due to their antagonism to worms, they may be revarded as specially useful. A very successful combinatiun is the following mixture :— 48 THE AORSE. Take of Spirit of Turpentine . . 2 ounces. Mucilage of Acacia . . : 6 cunces. Gum Ammoniacum . . . 4 ounce. handanami o.oo. see . 4 ounces. Waters = 6s 2 quarts. Mix, and give half-a-pint as a drench every night: the bottle must be well shaken before pouring out the dose. LARYNGITIS, ROARING, WHISTLING, &c. ONE OF THE MOST COMMON diseases among well-bred horses cf the present day, is the existence of some mechanical impediment to the passage of the air into the lungs, causing the animal to ‘make a noise.” ‘The exact nature of the sound has little or no practical bearing on the cause that produces it; that is to say, it cannot be predicated that .roaring is produced by laryngitis; nor that whistling is the result of a palsy of some particular muscle, but undoubtedly it may safely be asserted that all lesions of the larynx, by which the shape and area of its opening (rima glottidis) are altered and diminished, are sure to have a prejudicial effect upon the wind, and either to produce roaring, whistling, wheezing, or trumpeting, but which would result it might be difficult to say, although the precise condition of the larynx were known, which it cannot be during life. Until recently veterinary surgeons were puzzled by often finding on examination of a roarer’s larynx after death no visible organic change in the opening, and many were led to imagine that this part could not be the seat of the disease. On a careful dissection, however, it is found that a muscle or muscles whose office it is to dilate the larynx is wasted and flabby (crico- arytenoideus lateralis and thyro-arytenoideus). The other muscles are perhaps equally atrophied, but as their office is to close the opening, their defects are not equally snjurious, and at all events are not shown by producing an unnatural noise. ‘The cause of this wasting is to be looked for in pressure upon the nerve which sur- plics these muscles, and which passes through an opening in the posterior ala of the thyroid cartilage, so that whatever causes a dis- jlacement of that part will mechanically affect the nerve. For these several reasons it will be necessary to examine first of all into the several kinds of inflammation, &c., to which the lary1x is sub- ject, and then to investigate as far as we may, the nature, mode of detection. and treatment of the several conditions known to horsemen by the names of roaring, whistling, &c., which are only symptoms of one or other of the diseases to which allusion will presently be made. By ACUTE LARYNGITIS is meant a more than ordinary inflam- mation of the larynx, and not that slightly morbid condition in which the mucous membrane of that organ is always involved in “the passage of a ecld into the chest.” Jn the latter state the ear CHRONIC LARYNGITIS, . 49 detects no unusual sound, and indeed there is plenty of room for the air to pass. But in true laryngitis, on placing the ear near the throat, a harsh rasping sound is heard, which is sufficient at once to show the nature and urgency of the symptoms. ‘The mucous membrane is swollen, and tinged with blood; the rima glottidis is almost closed, and the air in passing through it produces the sound above described, which, however, is sometimes replaced by a stridu- lous or hissing one. In conjunction with this well-marked symp. tom there is always a hoarse cough of a peculiar character, and some considerable fever, with frequent respiration, and a hard, wiry pulse of seventy to eighty. The treatment must be of the most active kind for not only is life threatened, but even if a fatal result does not take place, there is great danger of permanent organic mischief to the delicate apparatus of the larynx, generally from the effusion of lymph into the submucous cellular membrane. aa eas 15 ounce.

THE HORSE is subject to inflammation of the substance of the heart (carditis) of a rheumatic nature, and of the fibro-serous ¢o7er- ing (pericarditis), but the symptoms are so obscure that no one but the professional veterinarian will be likely to make them out. Dropsy of the heart is a common disease in worn-out horses, and hypertrophy, as well as fatty degeneration, are often met with axong well-cunditiored animals. DISEASES OF BLOOD-VESSELS. 65 DISEASES OF THE BLOOD-VESSELS OF THE CUEST | AND NOSE. THE HORSE IS VERY SUBJECT TO HAMORRIIAGE from the nose, coming on during violent exertion, and many a race has been lost from this cause. Fat over-fed horses are the most likely to suffer from hemorrhage; but most people are aware of the risk in- curred in over-riding or driving them, and for this reason they are not so often subject to this accident (for such it is rather than a disease) as they otherwise would be. It is unnecessary to de- scribe its symptoms, as the gush of. blood renders it but too appa- rent, and the only point necessary to inquire into is, whether the lungs or the nasal cavities are the seat of the rupture of the vessel. In the former case the blood comes from both nostrils, and is frothy; while in the latter it generally proceeds from one only, and is perfectly fluid. The treatment should consist in. cooling the borse down by a dose of physic and a somewhat lower diet; but if the bleeding is very persistent, and returns again and again, a saturated solution of alum in water may be syringed up the nostril daily, or, if this fails, an infusion of matico may be tried, which is far more likely to succeed. It is made by pouring half a pint of boiling water on a drachm of matico-leaves, and letting it stand till cool, when it should be strained, and is fit for use. H®MORRHAGE FROM THE LUNGS is a far more serious affair, and its control requires active remedies if they are to be of any service. It may arise from the existence of an abscess in the lung of a phthisical nature, which implicates some considerable vessel; or it may be caused by the bursting of an aneurism, which is a dilatation of'a large artery, and generally occurs near the heart. ‘The treatment can seldom do more than prolong the life of the patient for a short time, and it is scarcely worth while to enter upon it. Bleeding from the jugular vein will arrest the internal hemorrhage, and must often be resorted to in the first instance, and there are internal medicines which will assist it, such as digi- talis and matico; but, as before remarked, this only postpones the fata. termina ion. 66 THE HORSE. CHAPTER IV. DISEASES OF THE ABDOMINAL VISCERA AND 1HEIR APPENDAGES (senerai remarks—Diseases of the Mouth and Throat—Gastritis— — Stomach Staggers— Dyspepsia — Bots—Inflammation of the Bowels—Colic—Diarrhea and Dysentery—Strangulation ana Rupture—Calcul in the Bowels—Worms—Disease of tke Liver—of the Kidneys—of the Bladder—of the Organs of Generation. GENERAL REMARKS. THOUGH NOT OFTEN PRODUCING what in horse-dealing.is con- sidered unsoundness, yet diseases of the abdominal viscera con- stantly lead to death, and frequently to such a debilitated state of the body, that the sufferer is rendered useless. J*ortunately for the purchaser, they almost always give external evidence of their presence, for there is not only emaciation, but also a staring coat and a flabby state of the muscles, which is quite the reverse of the wiry feel communicated to the hand in those instances where the horse is ‘‘ poor” from over-work in proportion to his food. In the latter case, time and good living only are required to restore the natural plumpness; but in the former, the wasting will either go on until death puts an end to the poor diseased animal, or he will remain in a debilitated and wasted condition, utterly unfit for hard work. DISEASES OF THE MOUTH AND TIIROAT. SEVERAL PARTS ABOUT THE MOUTH are liable to inflammation, which would be of little consequence in itself, but that it inter- feres with the feeding, and this for the time starves the hurse, and renders him unfit for his work, causing him to “quid” or return his food into the manger without swallowing it. Such are lampas, vives or enlarged glands, barbs or paps, gigs, bladders, and filaps,—all which are names given to the enlargements of the salivary ducts,—and carious teeth, or inflammation of their fangs. Besides these, the horse is also subject to sore throat, and stran- zies, which are accompanied by constitutional disturbance, and not only occasion “ quidding,” if there is any slight appetite, Lut they are also generally accompanied by a loss of that function. Sore THROAT.—When the throat inflames, as is evidenced by fulness and hardness of this part, and there is difficulty of swal- lowing, the skin covering it should immediately be severely sweated, or the larynx will be involved and irreparable injury done. The tincture of cantharides diluted with an equal part of spirit of tur- STKANGLES—LAMPAS. 6% pentine and a Hettle oil, may be rubbed in with a piece of spunge. until it produces irritation of the skin, which in a few hours will pe followed by a discharge from the part. Six or eight drachms of nitre may also be dissolved in the water which the horse drinks, with some difficulty, but still, as he is thirsty, he will take it. Sometimes eating gives less pain than drinking, and then the uitre may be given with a bran mash instead of the water. STRANGLES.—Between the third and fifth year of the colt’s life he is generally seized with an acute swelling of the soft parts between the branches of the lower jaw, accompanied by more or Jess sore throat, cough and feverishness. These go on increasing for some days, and then an abscess shows itself, and finally bursts. The salivary glands are often involved, but the matter forms in the cellular membrane external to them. The treatment should be addressed to the control of constitutional symptoms by the mildest measures, such as bran mashes with nitre in them, abstrac- tion of corn, hay tea, &c. At the same time the swelling should be poulticed for one night, or thoroughly fomented two or three ties, and then blistered with the tincture of cantharides. As soon as the matter can plainly be felt, it may be let out with a lancet; but it is very doubtful whether it is not the best plan to permit the abscess to_break. The bowels should be gently moved, by giving a pint, or somewhat less, according to age, of castor oil ; and afterwards two or three drachins of nitre, with half a drachm of tartar emetic, may be mixed with the mash twice a day, on which food alone the colt should be fed, in addition to gruel, and a little grass or clover if these are to be had, or if not, a few steamed earrots. The disease has a tendency to get well naturally, but if it is not kept within moderate bounds it is very apt to lay the foundation of roaring or whistling. Any chronic swelling which is left behind, may be removed by rubbing in a weak ointment of biniodide of mercury (one scruple or half drachm to the ounce; see page 300). LAMPAS is an active inflammation of the ridges, or “bars,” in tle hoof of the mouth, generally occurring in the young horse while Le is shedding his teeth, or putting up the tushes. Some- times, however, it comes on, independently of this cause from ovcr-feeding with corn after a run at grass. The mucous mem- brane of the roof of the mouth swells sc much that it projecta bel.w tke level of the nippers, and is so tender that all hard and dry food is refused. The treatment is extremely simple, consist: ing in the scarification of the part with a sharp knife or lancet, after which the swelling generally subsides, and is: gone in a day or two; but should it obstinately continue, as wi!l sometimes happen, a stick of lunar caustic must be gently rubbed over the part every day until a cure is completed. This is far better thay 68 THE HORSE. the red-hot iron, which was formerly so constantly used, with good effect it is true, and not accompanied by any cruelty, as the mucous membrane is nearly insensible, but the caustic is more rapid and effectual in stimulating the vessels to a healthy action. and on that score should be preferred.

WHERE VIVES, or chronically enlarged submaxillary glands, are met with, the application of the ointment of biniodide of mercury, according to the directions given at page 300, will almost certainly cause their reduction to a natural state. GASTRITIS. GASTRITIS (acute inflammation of the stemach) is extremely rare in the horse as an idiopathic disease ; but it sometimes occurs from eating vegetable poisons as food, or from the wilful introduc- tion of arsenic into this organ, or, lastly, from licking off corrosive external applications, which have been used for mange. The symp- toms from poisoning will a good deal depend upon the article which has been taken, but in almost all cases in which vegetable poisons have been swallowed, there is a strange sort of drowsiness. so that the horse does not lie down and go to sleep, but props him- self against a wall or tree with his head hanging almost to the ground. As the drowsiness increases he often falls down in his attempt to rest himself more completely, and when on the ground his breathing is loud and hard, and his sleep is so unnaturally sound that he can scarcely be roused from it. At length con- vulsions occur and death soon takes place. This is the ordinary course of poisoning with yew, which is sometimes picked up with the grass after the clippings have dried, for in its fresh state the taste is too bitter for the palate, and the horse rejects the mouthful of grass in which it is involved. May-weed and water parsley will also produce nearly similar symptoms. The treatment in each zase should be by rousing the horse mechanically, and at the same time giving him six or eight drachms of aromatic spirit of ammonia, in a pint or two of good ale, with a little ginger in it. This may be repeated every two hours, and the horse should be perpetually walked about until the narcotic symptoms are completely gone off, when a sound sleep will resture him to his natural state. ARSENIC, when given in large doses, with an intention to destroy STOMACH STAGGERS. 69 life, produces intense pain and thirst ;—the former, evidenced by an eager gauze at the flanks, pawing of the ground, or rolling; and sometimes. by each of these in succession. The saliva is secreted in increased quantities, and flows from the mouth, as the throat is venerally too sore to allow of its being swallowed. The breath soon becomes hot and fetid, and purging then comes on of a bloody mucus, which soon carries off the patient by exhaustion, if death does not take place from the immediate effects of the poison on the stomach and brain. Treatment is seldom of any avail, the most likely remedies being large bleedings, blisters to the sides of the chest, and plenty of thin. gruel to “sheathe the inflamed surface of the mucous membrane, which is deprived of its epithclial scales. CORROSIVE SUBLIMATE is sometimes employed as a wash in mange, or to destroy lice, when it may be licked off, and will occa- sion nearly the same symptoms as arsenic. The treatment consists in a similar use of thin starch or gruel; or, if the poison has recently been given wilfully, of large quantities of white of egg. STOMACH STAGGERS. THE EXACT NATURE of this disease has never been clearly made out, and it is now so rare, that there is little chance of its being satisfactorily explained. The symptoms would chiefly lead one to suppose the brain to be implicated ; but there is so close a sympathy between that organ and the stomach, that we can easily account in that way for the cerebral manifestations. A theory has been propounded, that it is seated in the par vagum, or pneumo- gastric nerve; and as all the parts with which that nerve is con- nected are affected, there is some ground for the hypothesis ; but It is not supported by the deqonstranion of anatomy, simply, per- haps, because of the difficulty in the way of prosecuting the pathology of the nerves. The first onset of the disease is marked by great heaviness of the eyes, soon going on to drowsiness; the head dropping into the manger, even while feeding is in progress. It generally makes its appearance after a long fast ; and it is sup- posed by some writers to be owing to the demands made by the stomach on the brain, when in an exhausted condition for want of its usual supplies. This theory is supported by the fact that, in the present day, when every horsemaster knows the danger of working his horses without fecding them at intervals of five, or at most six hours, the stomach staggers are almost unknown. Even when the disease shows itself at grass, it is almost always mani- val) THE HORSE. fested directly after the horse is first turned out, when he gorges himself with the much-coveted food, which has long been withheld, aud his brain is affected in a manner Similar to that which follows a long fast from every kind of fuod. In a short time, if the affection of the brain is not relieved, that organ becomes still more severely implicated, and convulsions or paralysis put an end to the attack. D-ring the course of the disease, the breathing is affected, and ‘here is generally an almost total cessation of the secretions of bile aud ur.ne, which may either be the cause or the effect of the con- dition of the brain. With this state of uncertainty as to the essence of the disease, it is somewhat empirical to lay down any rules for its treatment; and, as I before remarked, it is now so rare, that they are scarcely necessary. If care be taken to feed the horse properly, he will never suffer from stomach staggers in the stable; and at grass, the attack is seldom observed dntil he is beyond the reach of any remedies. Still, it may be as well to observe, that the usual plan of proceeding has been to take away blood, so as to relieve the brain, and to stimulate the stomach to get rid of its load, by the use of warm aperients, such as the following :— Take of Barbadoes Aloes . . . . . + 4 to 6 drachms. Tincture of Ginger . . . 3 drachms. Dissolve the aloes in a pint of hot water, then ‘add the tincture, and when nearly cool give as a drench. DYSPEPSIA. EVERY DOMES1*0 ANIMAL suffers in health if he is constant!y fed on the same articles, and man himself, perhaps, more than they do. Partridges are relished by him early in September, but toujours perdrtix would disgust the most inveterate lover of that article of food. Dogs are too often made to suffer from being fed on the same meal, flavored with similar flesh or broth. from one month to another. It is well known that cattle and sheep must change their pasture, 0. they soon lose condition ; and yet horses are expected to go on eating oats and hay for years together with- out injury to health; and at the same time they are often exposed to the close air of a confined stable, and to an irregular amount of exercise. We cannot, therefore, wonder that the master is often told that some one or other of his horses is “a little off his feed ;” nor should we b2 surprised that the constant repetition of the panacea for this, ‘‘ a duse of physic,” should at length permanently establish the condition which at first it would always alleviate. It is a source of wonder that the appetite continues so good as it DYSPEPSIA—BOTS. V1 dues, in the majority of horses, which are kept in the stable on the same kind of food, always from July to May, and often through the other months also. The use of a few small bundles of vetches, lucerne, or clover in the spring, is supposed to be quite sufficient to restore tone to the stomach, and undoubtedly they are better than no change at all; but at other seasons of the ear something may be done towards the prevention of dyspepsia, y varying the quality of the hay, and by the use of a few carrota once or twicé a week. In many stables, one rick of hay is made to serve throughout the whole or a great part of the year, which is a very bad plan, as a change in this important article of food is as much required as a change of pasture when the animal is at grass. When attention is paid to this circumstance, the appetite will seldom fail in horses of a good constitution, if they are regu- larly worked; but without it, resort must occasionally be had to a dose of physic. It is from a neglect of this precaution that so many horses take to eat their litter, in preference to their hay; for if the game animal was placed in a straw-yard, without hay, for a month, and then allowed access to both, there would be little doubt that he would prefer the latter. Some horses are naturally so voracious, that they are always obliged to be supplied with less than they desire, and they seldom suffer from loss of appetite; but delicate feeders require the greatest care in their management. When the stomach suffers in this way, it is always desirable to try what a couplete change of food will do before resorting to medicine ; and, if it can be obtained, green food of some kind should be chosen, or if not, carrots, or even steamed potatoes. In place of hay, sound wheat or barley straw may be cut into chaff, and mixed with the carrots and corn; and to this a little malt-dust may be added, once or twice a week, so as to alter the flavor. By con- tinually changing the food in this way, the most dyspeptic stomach may often be restored to its proper tone, without doing harm with one hand while the other is doing good, as is too often the case with medicine. The use of the fashionable “ horse- fecds” of the present day will serve the same purpose; and if the slight changes I have mentioned do not answer, Thorley’s or Henri’s food may be tried with great probability of success. BOTS. THE LARV# of the estrus equi, a species of gadfly, are often found in large numbers, attached by a pair of hooks with which they are provided, to the cardiac extremity of the stomach; they are very rarely met with in the true digestive portion of this organ, but sometimes in the duodenum or jejunum in small numbers. A group of these larvae, which are popularly called bots, are repre- sented on the next page, but sometimes nearly ali the cardiac ex. V2 THE HORSE. tremity of the stomach is occupied with them, the interstices being vecupied by little projections which are caused by those that have let go their hold, and have been expelled with the food. Several of these papillee are shown on the engraving, which delineates alsa the appearance of the bots themselves, so that no one can fail to recognise them when he sees them. ‘This is important, for it often “ “% WY eo - ‘ai Fre. 18.—Grour OF BOTS ATTACHED TO TBE STOMACH. happens that a meddlesome groom when he sees them expelled from or hanging to the verge of the anus, as they often do fora short time, thinks it necessary to use strong medicine; whereas in the first place he does no good, for, none is known wkich will kill the larva without danger to the horse, and in the second, if he will only have a little patience, every bot will come away in the natural course of things, and until the horse is turned out to grass, during the season when the cestrus deposits its eggs, he will never have another in his stomach. THE @STRUS EQUI comes out from the pupa state in the middle and latter part of summer, varying according to the season, and the female soon finds the proper nidus for her eggs in the hair of the nearest herse turned out to grass. She manages to glue them to the sides of the hair so firmly that no ordinary friction will get rid of them, and her instinct teaches her to select those parts within reach of the horse’s tongue, such as the hair of the fore legs and sides. Here they remain until the heat of the sun hatches them, when, being no larger in diameter than a small pin, each iarva is licked off and carried down the gullet to the stomach, to the thick epithelium of which it soon attaches itself by its hooks. Ilere it remains until the next spring. having attained the size INFLAMMATION OF THE BOWELS. 73 which is represented in the engraving during the course of the first two months of its life, and then it fulfils its allottc 1 career, by letting go and being carried out with the dung. On reaching the outer air it soon assumes the chrysalis condition, and in three or four weeks bursts its covering to become the perfect insect. FRoM THIS HIsTORY it will be evident that no preventive measures will keep off the attacks of the fly when the horse is af grass, and, indeed, in those districts where they abound, they will deposit their ova in the hair of the stabled horse if he is allowed to stand still for a few minutes. The eggs are, however, easily recognised in any horse but a chestnut, to which color they closely assimilate, and as they are never deposited in large numbers on the stabled horse they may readily be removed by the groom. Unlike other parasites, they seem to do little or no harm, on account of the insensible nature of the part of the stomach to which they are attached, and, moreover, their presence is seldom discovered until the season of their migration, when interference is uncalled for. On all accounts, therefore, it 1s unnecessary to enter into the question, whether it is possible to expel them; and even if by chance one comes away prematurely it will be wise to avoid interfering by attempting to cause the expulsion of those left behind. INFLAMMATION OF THE BOWELS. (Peritonitis and Enteritis.) A &EFERENCE to the cut of the abdomen and its contents, oppo- site page 350, will explain that there are two divisions of the abdominal serous sae, one of which lines the walls of the cavity, and the other covers the viscera which lie in it. In human medi- cine, when the former is inflamed, the disease is termed peritonitis, and when the latter is the subject of inflammatory action it 1s ealled enteritis. But though in theory this distinction is made, in practice it is found that the one seldom exists without the other being developed to a greater or less extent. Veterinary writers have generally taken the nomenclature adopted in human ana- tomy and pathology, but in regard to the inflammations of the bowels they define peritonitis as inflammation of the peritoneal or serous coat, and enteritis as inflammation of the muscular coat. My own belief is, that during life it is impossible by anv known symptoms to distinguish the exact Joca/e of any inflammation of the bowels but that of their mucous lining, which will presently he described, and that wherever the actual serous covering of the bowels is involved the muscular fibres beneath it will be implicated, but that the serious and fatal symptoms manifested in such cases are not dependent upon the latter, but are due entirely to the lesions of the serous coat. I have examined numberless fatal v4 THE HORSE cast of supposed enteritis, and have uniformly found signs of inflammation of the serous investment, sometimes implicating the muscular fibres beneath, and often extending to the peritoneal lining of the walls of the abdomen, but I have never yet seen marks of inflammation in the muscular tissue without their serous covering being affected toa much greater extent. I believe there- fure that the distinction is erroneously founded, and that, theoreti- eally, the same definition should be made of the two diseases as is in use by human pathologists, though practically this is of little im portance. There is no well made out inflammation of muscular tissue (except that of the heart) in which the symptoms are so urgent and so rapidly followed by a fatal issue as in the latter stages of the disease described by Mr. Percivall under the head enteritis, as follows:—‘‘'The next stage borders on delirium. The eye acquires a wild, haggard, and unnatural stare—the pupil dilates— his heedless and dreadful throes render approach to him quite perilous, he is an object not only of compassion but of apprehen- sion, and seems fast hurrying to his end—when all at once, in the midst of agonizing torments he stands quiet, as though every pain had left him and he were going to recover. His breathing becomes tranquillized—his pulse sunk beyond all perception—his body bedewed with a cold clammy sweat—he is in a tremor frum head to foot and about the legs and ears has even a dead-like feel. The mouth feels deadly chill—the lips drop pendulous, and the eye seems tnconscious of objects. In fine, death, not recovery, is at kand. Mortification has seized the inflamed bowel—pain can no longer be felt in that which a few minutes ago was the seat of most exquisite suffering. He again becomes convulsed, and in a few more struggles less violent than the former he expires.” Analogy would lead any careful pathologist to suppose that such symptoms as these are due to some lesion of a serous and not a muscular tissue, and, as I before remarked, I have satisfied myself that such is really the case. I have seen lymph, pus, and serum etfused in some cases of enteritis, and mortification extending toa large surface of the peritoneal coat in others, but I have never examined a single case without one or the other of these morbid results. It may be said that so long as the symptoms are correctly described their exact seat is of no consequence; but in this instance it is probable that the ordinary definition of enteritis as an inflammation of the muscular coat may lead to a timid practice in its treatment, which would be attended with the worst results. I have no fault to find with the usual descripticns of the twe diseases, or with their ordinary treatment, but I protest against the definition which is given of them. AN EXAMINATION OF THE CAUSE of inflammation of the bowels 38 the ouly means by whieh the one form can be distinguished INFLAMMATION OF THE BOWELS. ve Frura the other. If it has been brought about from exposure te ceuld, or from over-stimulating medicines given for colic, the proba- bility is that the serous covering of the intestines themselves 3s chiefly involved ; while if it has followed castration it may gener: ally be concluded that the peritoneal lining of the abdominal muscles has taken on inflammatory action by an immediate exten sion from the serous lining of the inguinal canal, which is con tinuous with it. In each case, however, the symptoms are as nearly as may be the same, and without knowing the previous history I believe no one could distinguish the one disease from the other—nor should the treatment vary in any respect. ''HE SYMPTOMS of peritoneal inflammation vary in intensity, and in the rapidity of their development, but they usually show themselves in the following order :—At first there is simple loss of appetite, dulness of eye, and a general uneasiness, which are soon followed by a slight rigor or shivering. The pulse becomes rapid, but small and wiry, and the horse becomes very restless, pawing his litter, and looking back at his sides in a wistful and anxious manner. In the next stage all these signs are aggravated; the hind legs are used to strike at but not touch the belly; and the horse lies down, rolls on his back and struggles violently. The pulse becomes quicker and harder, but is still small. The belly is acutely tender and hard to the touch, the bowels are costive, and the horse is constantly turning round, moaning, and regarding his flanks with the most anxious expression of countenance. Next comes on the stage so graphically described by Mr. Percivall in the passage which I have quoted, the whole duration of the attack being from twelve to forty eight hours in acute cases, and extend- ing to three or four days in those which are denominated sub- acute. In the treatment of this disease, as in all those implicating serous mombrane, blood must be taken largely, and in a full stream, the quantity usually required to make a suitable impression being from six to nine quarts. The belly should be fomented with very hot water, by two men holding against it a doubled blanket, dipped in that fluid, which should be constantly changed, to keep up the teraperature. The bowels should be back-raked, and the follow- ing drench should be given every six hours till it operates, which should be hastened by injections of warm water. Dake of himseed ois te. 8.

The diet should be con. fined to thin gruel or bran mashes, and no hay should be allowed until the severity of the attack has abated. To DISTINGUISH this disease from colic is of the highest import- ange, and for this purpose it will be necessary to describe the symptoms of the latter disease, so as to compare the two together COLIC. IN THIS DISEASE there is spasm of the muscular coat of the intestines, generally confined to the caecum and colon. Various names have been given to its different forms, such as the fret, the gripes, spasmodic colic, flatulent colic, &e , but they all display the above feature, and are only modifications of it, depending upon th. cause which has produced it. In spasmodic colic, the bowels are not unnaturally distended, but in flatulent colic their distension by gas brings on the spasm, the muscular fibres being stretched to so great an extent as to cause them to contract irregularly and with a morbid action. Sometimes, when the bowels are very cos- tive, irritation is established as an effort of nature to procure the dislodyment of the impacted faecal matters, and thus a third cause of the disease is discovered. The exact nature and cause are always to be ascertained from the history of the case, and its symptoms, and as the treatment will especial:y be conducted with a view to a removal of the cause, they ure of the highest import- ance. The symptoms in all cases of colic, by which it may be distinguished from the last-described disease, are as follows: In both acute pain is manifested by stamping, looking at the flanks, and rolling; but in enteritis the pain is constant, while in colic, there are intervals of rest, when the horse seems quite easy, and often begins to feed. In both the poor animal strikes at his belly; but in the former he takes great care not to touch the skin, while in the latter (colic) he w'll often bring the blood by his desperate efforts to get rid of his annoyance. In enteritis the belly is hot and exquisitely tender to the touch, but in colic it is not unnatur- ally warm, and gradual pressure with a broad surface, such as the whole hand, always is readily borne, and generally affords relief. The pulse also is little affected in colic; and, lastly, the attack is very much more sudden than in peritoneal inflammation. SuCH ARE THE GENERAL SIGNS by which a case of colic may be distinguished from inflanimation of the bowels, but beyond this it is necessary to investigate whether it is pure spasmodie colic, or produced by flatulence, or by an obstruction in the bowels. COLIC. WY IN SPASMODIC COLIC all the above symptoms are displayed, with- put any great distension of the abdomen ; and if the history of the ease is gone into, it will be found that after coming in heated the horse has been allowed to drink cold water, or has been exposed iv an exhausted state to a draught of air. IN FLATULENT CoLtc the abdomen is enormously distended ; the attack is not so sudden, and the pain is not so intense, being rather to be considered, in the average of cases, as a high degree of un- easiness, occasionally amounting to a sharp pang, than giving the idca of agony. In aggravated attacks, the distension is s0 enor- mous as to leave no doubt of the nature of the exciting cause. Here also the spasms ave often brought on by drinking cold water while the horse is in a heated and exhausted state. WHERE THERE IS A STOPPAGE IN THE BOWELS to cause the spasm, on questioning the groom, it will be found that the dung for some days has been hard and in small lumps, with occasional patches of mucus upon it. In other respects there is little vw dis- tiuguish this variety from the last. The treatment must in all cases be conducted on a totally differ- ent plan to that necessary when inflammation is present. Bleeding will be of no avail, at all events in the early stages, and before the disease has gone on, as it sometimes will, into an inflammatory condition. On the other hand, stimulating drugs, which would be fatal in enteritis, will here generally succeed in causing a return of healthy:mustular action. The disease is indeed similar in its essential features to cramp in the muscles of the human leg or arm, the only difference being that it does not as speedily dis- appear, because it is impossible to get_at the muscular coat of the intestines, and apply the stimulus of friction. AS SOON AS A CASE IS CLEARLY MADE OUT TO BE OF A SPAS- MODIC NATURE, one or other of the following drenches should be given, the choice being made in proportion to the intensity of the aAymptoms :— F.Sulphuric.

Hot water should also be applied to the abdomen, as described under the head cf Enteritis, and if an enema pump is at hand, large quantities of water, at a temperature of 100° Fahrenheit, should be injected per anum, until in fact the bowel will hold no more without a dangerous amount of force. IN FLATULENT COLIC the same remedies may be employed, but the turpentine mixture is here especially beneficial. The use of warm water injections will often bring away large volumes of wind, which at once affords relief, and the attack is cured. Sometimes, however, the distension goes on increasing, and the only chance of recovery consists in a puncture of the caecum, as it lies high in the right flank, where, according to French veterinary writers it may often be opened when greatly distended, without dividing the serous covering. The operation, however, should only be per- formed by an experienced hand, as it is one of great danger, and a knowledge of the anatomy of the parts concerned is required to select the most available situation. THE TREATMENT OF IMPACTION must be completely a pos- terior’, for all anterior proceedings with aperient medicines will only aggravate the spasms. Injection of gallons of warm water or of cruel containing a quart of castor oi] and halfa pint of spirit of turpentine, will sometimes succeed in producing 2 passage, and at the same tite the spasm may be relieved by the exhibition at the mouth of one ounce of laudanum and the same quantity of sulphuric ether. If there is any tenderness of the abdomen, or the pulse has a tendency to quicken, it will be better to resort to bleeding, which alone will sometimes cause the peristaltic action to be restored in a healthy manner. The case, however, requires great paticnce and judgment, and as no great good can often be effected, it is highly necessary to avoid doing harm, which can hardly be avoided if the remedies employed are not at once suc- cessful. WHEN THE URGENT SYMPTOMS of colic in any of its forms are reliuved, great care must be exercised that a relapse does not take place from the use «f improper food. The water should be care- fully chillod, and a warm bran mash should be given, containing in it half a feed of bruised oats. Nothing but these at moderate inter- vals, in the shape of food or drink, : should be allowed for a day or two, and then the horse may gradually return to his customary treatment, avoiding, of course, everything which may appear to have contributed to the development of colic. DIARRHG@A AND DYSENTERY. A DISTINCTION is attempted to be made between these two dis- eases,—the forincr name being confined to an inflammation of the muccus membrane of the small intestines, while the latter is said mw DIARRHG@A AND DYSENTERY. oo to reside in the large. It is very difficult, however, if not impos: sible, to distinguish the one from the other by the symptoms dur- ing life, and in ordinary practice they may be considered is one disease, the treatment depending in great measure on the exciting vause. his in most cases is to be found in the use of too violent “physic,” or in not resting the horse after it has begun to act until some hours after it has completely “set.” Sometimes it depends on the cells of the colon having long been loaded with feeces, which causes, at length, their mucous lining to inflame, the consequent secretion having a tendency to loosen them and pro- cure their dismissal, either by solution or by the forcible contrac- tion of the muscular coat. This last disease is known by the name of ‘‘ molten grease” to old-fashioned farriers, the clear mucus which envelopes the lumps of feeces being supposed to be derived from the internal fat that is generally plentifully developed in the highly fed horses that are especially subject to the attack. For practical purposes, therefore, we may consider the different forms under the head of superpurgation, diarrhoea, and dysentery, meaning by the Jast name that condition which is brought about by and attended with a discharge of lumps of hard fecal matter enveloped in mucus. SUPERPURGATION is sometimes so severe as to place a delicate horse in great danger. When the action of the bowels has gone on for three or four days consecutively, and there is no disposition to “set,” the eyes become staring and glassy, the pulse is feeble, and the heart flutters in the most distressing manner; the mouth has a peculiarly offensive smell, the tongue being pale and covered with a white fur having a brown centre. The abdomen is gene- rally tucked tightly up, but in the later stages large volumes of gas are evolved, and it becomes tumid. The treatment should cousist in the exhibition of rice, boiled till quite soft, and if not taken voluntarily, it should be given as a drench, mixed into a thin liquid form with warm water. If the case is severe, one or two ounces of laudanum may be added to a quart of rice milk, and given every time the bowels act with vio- lence. Ora thin gruel may be made with wheat meal, and the jaudanum be mixed with that instead of the rice. A perseverance in these remedies will almost invariably produce the desired effect, if they have not been deferred until the horse is very much ex- hausted, when a pint of port wine may be substituted for the Jaudanum with advantage. IN PtARRHEA resulting from cold, or over-exertion, the treat “ment should be exactly like that prescribed for superpurgation, but it ~vill sometimes be necessary to give chalk in addition to the remed gs there alluded to. The rice or flour-milk may be admin > 80 THE HORSE. istered as food, and the following drench given by itself every time there is a discharge of liquid faeces :— Tako of Powdered Opium . .. . . « 1 drachm.

IN DYSENTERY (or molten grease) it is often necessary to take a little blood away, if there is evidence of great inflammation in the amount of mucus surrounding the faeces, and when apetient medicine does not at once put a stop to the cause of irritation by bringing the lumps away from the cells of the colon. Back-raking, and injections of two ounces of lzudanum and a pint of castor oil with gruel, should be adopted in the first instance, but they will seldom be fully efficient without the aid of linseed oil given by the mouth. A pint of this, with half a pint of good castor oil, will generally produce a copious discharge of lumps, and then the irri- tation ceases without requiring any further interference. Whenever there is diarrhoea or dysentery present to any extent, ricc-water should be the sole drink. STRANGULATION AND RUPTURE. MECHANICAL VIOLENCE is done to the stomach and bowels in Various ways, but in every case the symptoms will be those of severe inflammation of the serous coat, speedily followed by death, if not relieved when relief is possible. Sometimes the stomach is ruptured from over-distension—at others the small intestines have been known to share the same fate, but the majority of cases are duc to strangulation of a particular portion of the bowels, by being tied or pressed upon by some surrounding band. This may hap- pen either from a loop of bowel being forced through an opening in the mesentery or mesocolon, or from a band of organized lymph, the result of previous inflammation—or from one portion of the bowels forcing itself into another, like the inverted finger of a glove, and the included portion being firmly contracted upon by the exterior bowel, so as to produce dangerous pressure (intussus- ception), or, lastly, from a portion or knuckle of intestine forcing its way through an opening in the walls of the abdomen, and then ealled hernia or rupture, which being pressed upon by the edges of the opening becomes strangulated, and if not relieved inflam&s, and then mortifies. None of these cases are amenable to treat- ment (and indeed they cannot often be discovered with certainty during life, the symptoms resembling those of enteritis), exenpt CALCULI IN THE 30WELS. 81 strangulated hernia, which should be reduced either by the pres. sur+ of the hands, or by the aid of an operation with the knife— which will be described under the chapter which treats of the seve- ral operations. Whenever inflammation of the bowels is attended with obstinate constipation, the walls of the abdomen should be carefully examined, and especially the inguinal canal, scrotum, and uavel, at which points in most cases the hernia makes its appear- ance. A swelling at any other part may, however, contain a knuckle of intestine, which has found its way through the abdo- minal parietes in consequence of a natural opening existing there. or of one having been made by some accidental puncture with a spike of wood or iron. The swelling is generally round, or nearly so, and gives a drum-like sound on being tapped with the fingers. It feels hard to the touch in consequence of the contents being constricted, but it gives no sensation of solidity, and may be gene- rally detected by these signs. None but an educated hand can, however, be relied on to distinguish a ventral hernia from any other tumor. When it occurs at the scrotum or navel the case is clear enough. CALCULI IN THE BOWELS. A STOPPAGE IN THE BOWELS sometimes obstinately persists, in spite of all kinds of remedies, and, death taking place, it is found on examination that a large calculus has blocked up the area of the canal. Sometimes one of these calculi is found in the stomach, but this is extremely rare. On making a section they are found to consist of concentric layers of bran, chaff, and other hard par- ticles of the food, mixed generally with some small proportion of earthy matter, and arranged around some foreign body, such as a piece of stone from tke corn, or the head of a nail, Treatment is out of the question, 2s it is impossible to discover the calculus during life, and even if it could be ascertained to exist, no remedy is known for it. Those who are curious about the composition of these calculi, will be pleased with the following letter by Mr. Buck- land, surgeon to the 1st Life Guards, in reply to an inquiry made in The Ficld as to the composition of a calculus found in a horse belonging to a correspondent :— “Mr. C. Pemberton Carter having, in his interesting letter, re- quested me to throw some light upon this subject, | have great pleasure in giving what little information I am able to afford, with apologies for delay, as Aldershot camp is by no means a favorable spot for'scientific investigations or literary pursuits. As regards the actual composition of calculi such as he has sent, we learn from the catalogue of the museum of the Royal College of Sur- econs that they are composed for the most part of the phosphate of magnesia and ammonia, with small quantities of phosy hate of ce 82 THE HORSE. time. They also contain an animal and extractive matter, to wnich the brown color of the calculus is owing. ‘They also contain mu riates of soda, and various alkaline salts derived from the intestinal juices. The animal matter resembles that of all other concretions, and separates in concentric laminze when the calculus is dissol red in an acid. In more impure varieties, grains of sand, portions of hay, straw, &c., are frequently found imbedded in the calculus, and there is one specimen in the museum which contains an entire layer of vegetable hairs. Mr. Carter remarks that ‘ his impression is that the calculus is made up of bran’ (chemically speaking). H[e is not far wrong, for we read in the College catalogue, ‘ Most authorities agree that these calculi are formed from phosphate of magnesia, coutuined in wheat, oats, hay, &c., and this opinion de- rives confirmation from the circumstance that they occur most fre- quently in mél/ers’ and brewers’ horses, whish are fed upon grains, bran, and substances known to contain a much larger proportion of magnesian salts than other vegetable matters.’ Mr. Carter has detected minute portions of wheat, oats, and hay in the calculus, which therefore may be said to consist of two substances, viz., the vegetable and the mineral. So much, then, for the composition af the calculus; now for its mechanical structure. Most decidedly it may be compared to an onion, layer being packed over layer, so as In section to present a ringed appearance. We may also liken it to other objects. It has lately struck me to examine the struc- ture of a common ericket-ball, which combines hardness, light- ness, and elasticity in such an admirable way. Upon making a section, I found the cricket-ball to be composed of layers, one over the other, round a central nucleus. The layers are composed of leather, alternated with a vegetable fibre, the nucleus being a bit of cork. The caleulus in the horse is formed in a similar way. The nueleus in Mr. Carter’s specimen is a bit of flint; in a capital instance I have in my own collection, of a eommon shot, about No. 5 size, which has been crushed by the horse’s teeth, and sub- sequentiy swallowed; in another instance, of a chair nat! of brass; in another of a single oat-seed; in another of a minute bit of cinder, and so on, as it seems to be aLsolutely necessary that these calculi should have a commencement—a starting-point. Where is the school-boy who can make a gigantic snowball without be- ginning with a small lump of snow or a stone, as a nucleus upon which he builds all the rest? ‘Mr. Carter seems to wonder at the weight of the specimen, 5 ibs.; this is by no means a large size; in the museum of the Royal College of Surgeons we have a very fine collection of eai- euli, the largest, taken from the intestines of a horse, weighs no less than 17 Ibs , and is about the size and shape of an ordinary skittle-ball. In the case where this is contained he will see many CALCULI IN THE BOWELS—WORMS. 83 othar specimens, cut in sections to show the nuclei; he will ob- serve that caleuli also form in the intestines of the camel and of the elephant, and even in the wild horse, for there is a good specl- men from the intestines of a Japanese wild horse. Stones, not true calculi, are sometimes found in animals, which have been actually swallowed by them, and have not been chemically formed in this walking laboratory. There is a case containing several pebbles—thirty in number—found in the stomach of a cow at Barton-under-Needwood, Burton-on-Trent. These stones belong to the geological formation of the neighborhood ; it is curious to see how they have been acted on by the action of the stomach. for they are highly glazed and polished. I have seen specimens of gravel pebbles which I took from the gizzard of an ostrich, which are as highly polished as an agate marble. The bird swallowed the stones to assist its digestion; the cow out of a morbid appe- tite. I know of a somewhat similar instance that lately happened : A young lady was taken ill, and died of very strange symptoms ; it was subsequently ascertained that the stomach was quite filled with human hair, which had moulded itself into the shape of the interior of that organ. The poor girl had naturally very long and beautiful hair, and she had an unfortunate habit of catching the loose hairs with her lips and swallowing them; in time they felted together, became a solid mass, and killed her—a warning to other young ladies which should not be neglected. In the lower animals we frequently find rolled balls of hair from the creatures licking themselves. I have seen one at Bristol from a lioness; it is formed of hairs licked with her rough tongue from her cubs. Curious concretions are found in goats, &c., called ‘bezoar’ stones ; they were formerly supposed to have medicinal virtues: of this at an- other time. ¥. T. Buckianp.” WORMS. INTESTINAT, WORMS in the.horse are chiefly of two species, both belonging to the genus ascaris. Bots, as inhabiting the stomach, have already been described with that organ; and, moreover, they should never be confounded with what are called properly and scientifivally, ‘“ worms.”’ f these, the larger species resembles the common earthworm in all respects but color, which is a pinkish white. It inhabits the small intestines, though it is sometimes, but very rarely, found in the stomach. The symptoms are a rough, staring, hollow coat-—a craving appetite—more or less emaciation— the passage of mucus with the faeces, and very often a small por- tion of this remains outside the anus, and dries there. That part generally itches, and in the attempt to rub it the tail is denuded of hair; but this may arise from vermin in it, or from mere irri- tation of the anusdrom other causes. When these several symp- 84 THE TORSE. toms are combined, it may with some degree of certainty be sup- posed that there are worms in the intestines, but before proceeding to dislodge them, it is always the wisest plan to obtain proof’ posi- tive of their existence, by giving an ordinary dose of physic, when, en watching the evacuations, one or more worms may generally be discovered if they are present. When the case is clearly made out the plan of treatment is as follows :— Paks of. Tortar:P mee? \.%, de masiecn Salers metas ; drachm. Powdered Ginger .. . : - 4 drachm. Linseed Meal sufficient to make into a ball with boiling water. One should be given every morning for a week, then a dose of physic; linseed oil being the most proper. Let the stomach rest a week; give another course of balls and dose of physic, after which let the horse have a drachm of sulphate of iron (powdered) twice a day with his feed of corn. There is no medicine which is so effectual for removing worms in the horse as tartar emetic, and none which is so entirely innocu- ous to the stomach. Calomel and spirit of turpentine were formerly in use as vermifuges, but they are both dangerous drugs; the former, if given for any length of time, causing great derangement of the stomach and liver; and the latter often producing consi- derable inflammation after a single dose, if sufficiently large to cause the expulsion of the worms. Linseed oil given in half. -pint doses every morning is also an excellent vermifuge, but not equal to the tartar emetic. If this quantity does not ‘relax the bowels it may be increased until they are rendered slightly more loose than usual, but avoiding anything like purgation. The smaller species of intestinal worm chiefly inhabits the rec- tum, but is occasionally found in the colon and caecum. It pro- duces great irritation and uneasiness, but has not the same preju- dicial effect on the health as the larger parasite. It is about one to two inches in length, and somewhat smaller in diameter than a crow quill. These worms are commonly distinguished as ascarides, but both this species and the round worm belong to the genus ascarts. The term thread worm is more correctly applied, as they are not unlike sections of stout thread or cotton. The only symp- tom by which their presence can be made out is the rubbing of the tail, when if, on examination, no vermin or eruption is found in the dock, it may be presumed that worms exist in the rectum, The remedy for these worms is by the injection every morning fer a weck of a pint of linseed oil, containing two drachms of spirit of turpentine. This will either kill or bring away the worms, with the exception of a few which are driven by it higher up into tha DISEASES OF THE LIVER AND KIDNEYS. 85 solon, but by waiting a week or ten days (during which time they will have re-entered the rectum) and then repeating the process, they may generally be entirely expelled. The sulphate of iron must be given here, as before described. DISEASES OF THE LIVER. THE LIVER OF THE HORSE is less liable to disease than that of any other domestic animal, and the symptoms of its occurrence are so obscure that it is seldom until a post-mortem examination that a discovery is made of its existence. This unerring guide, however, informs us that the liver is sometimes unnaturally en- larged and hard, at others softened, and in others again the sub- ject of cancerous deposits. It is also attacked by inflammation, of which the symptoms are feverishness; rapid pulse, not hard and generally fuller than usual; appetite bad; restlessness, and the patient often looking round to his right side with an anxious ex- pression, not indicative of severe pain. Slight tenderness of the right side; but this not easily made out satisfactorily. Bowels generally confined, but there is sometimes diarrhoea. Very fre- quently the whites of the eyes show a tinge of yellow, but any- thing like jaundice is unknown. The treatment must consist in the use of calomel and opium, with niild purging, thus :— Take of Calomel, Powdered Opium, of each one drachm. Linseed Meal and boiling water enough to make into a ball, which should be given night and morning. Every other day a pint of Linseed Oil should be administered. The diet should if possible be confined to green food, which will do more good than medicine; indeed, in fine weather, a run at grass during the day should be preferred to all other remedies, taking eare to shelter the horse at night in an airy loose-box. DISEASES OF THE KIDNEYS. THESE ORGANS are particularly prone to disease, and are subject to inflammation ; to diabetes, or profuse staling ; to hematuria, or a d'scharge of blood, and to torpidity, or inaction. INFLAMMATION OF THE KIDNEYS (vephritis) is generally pro- duced by an exposure of the loins to wet and cold, as in carriage. horses standing about in the rain during the winter season. Some- times it follows violent muscular exertion, and is then said to be caused by a strain in the back, but in these cases there is probably an exposure to cold in a state of exhaustion, or by the rupture of a branch of the renal artery or vein, as the inflammation of one organ can scarcely be produced by the strain of another. The symptoms are a constant desire to void the urine, which is of a very dark color—often almost black. Great pain, as evidenced by 24 86 THE HORSE. the expression of countenance and by groans, as well as by frequent wistful looks at the loins. On pressing these parts there is some tenderness, but not excessive, as in rheumatism. The pulse is quick, hard, and full. The attitude of the hind quarters is pecu- liar, the horse standing in a straddling position with his back arched, and refusing to move without absolute compulsion. It is sometimes difficult to distinguish nephritis from inflammat::n of the neck of the bladder, but by attending to the state of the urine, which is dark brown or black in the former case, and nearly of a natural color in the latter, the one may be diagnosed from tho other. To make matters still more clear, the oiled hand may be passed into the rectum, when in nephritis the bladder will be found contracted and empty (the urine being so pungent as to irritate that organ), while in inflammation or spasm of its neck, it will be distended, often to a large size. The treatment to be adopted must be active, as the disease runs a very rapid course, and speedily ends in death if neglected. A large quantity of blood must at once be taken. The skin must be acted on energetically, so as to draw the blood to its surface, and if a Turkish bath (see page 215) is at hand, it will be highly beneficial. If not, the application of hot water, as recommended at page 342, may be tried, and in many cases it has acted like a charm. Failing the means for carrying out either of these remedies, the loins should be rubbed with an embrocation consisting of olive oil, liquid ammoniz and laudanum in equal parts, but cantharides and turpentine must be carefully avoided, as likely to be absorbed, when they would add fuel to the fire. A fresh sheepskin should be warmed with hot (not boiling) water, and applied over the back, and the liniment should be rubbed in profusely every hour, restoring the skin to its place im- mediately afterwards. Mustard is sometimes used instead of am- wonta, and as it is always at hand, it may form a good substitute, but it is not nearly so powerful an irritant to the skin as the latter, especially when evaporation is prevented by the sheepskin, or by a piece of any waterproof article. A mild aperient may be given, linseed oil being the best form, but if the bowels continue ob- stinate, and it is necessary to repeat it, eight or ten drops of croton oil may be added to a pint of the oil, great care being taken to assist its action by raking and injection, the latter being also use- ful as a fomentation to the kidneys. The diet shonl1 consist of scaided linseed and bran mashes, no water being allowed without containing sufficient linseed tea to make it slightly glutinous, but not so much so as to nauseate the patient. If the symptoms are not greatly abated in six or eight hours, the bleeding must be re- peated, for upon this remedy the chief dependence must be placed. A mild and soothing drench, composed of half an ounce of ear. bonate of soda, dissolved in six ounces of linseed tea, way be given DISEASES OF THE KIDNEYS. 87 every six hours, but little reliance can be placed upon it. The inflammation either abates after the bleeding, or the horse dies in a very tew hours. DIABETES of late years has been much more frequent than was formerly the case, and especially among race-horses and hunters, probably owing to the enormous quantities of corn which they are allowed in the present day. But whatever may be the cause, the symptoms are clear enough, the horse constantly staling and_pass- ing large quantities of urine each time. he treatment should be conducted on the principle that the cause should if possible be asvertained and removed. Mowburnt hay will often bring on dia- betes, and new oats have a similar tendency in delicate horses. In any case it is wise to make a total change in the food as far as it can possibly be done. Green meat will often check it at once, and a bran-mash containing a few carrots has a similar chance of doing good. With these alterations in the quality of the food attention should also be paid to the quantity of the corn, which should be reduced if more than a peck a day has been given, and beans should be substituted for a part of the oats. Half a drachm of the sul- phate of iron (powdered) should be mixed with each feed (that is, four times a day), aud the horse should be well clothed and his legs warmly bandaged in a cool and airy (but not cold and draughty) loose box By attention to these directions the attack may gener- ally be subdued in a few days, but there is always a great tendency to its return. Should it persist in spite of the adoption of the measures already recommended, the following ball may be tried :— Take of Gallic Acid aa oY nee eee Se Unena. Optam-— 4.02 ; : 8 sah didrwehm: Treacle and Linseed Meal enough ms ails pa a ball, which should be given twice a day. HamatTurFA, like diabetes, is easily recognised by the presence of blood in greater or less quantities passed with the urine. — It is not, however, of the bright red color natural to pure blood, but it is more or less dingy, and sometimes of a smoky-brown color, as occurs in inflammation. Bloody urine, however, may often be passed without any sign of that condition, and therefore unaccom- panied by pain, or any other urgent symptom. The causes are exceedingly various. Sometimes a parasitic worm (Strongylus igas) has been discovered, after death from hzematurea, in the Gey, and was apparently the cause of the mischicf, At others, this organ has been found disorganized by cancer or melanosis— and again a sharp calculus has been known to bring on considcr- able bleeding, and this last cause is by no means unfrequent., The symptoms are the existence of bloody urine unaccompanied by pain or irritation, marking the absence of nephritis. As to treatment, littl: cam be done in severe cases, and mild ones only require rest, 88 THE HORSE. a dose of physic, and perhaps the abstraction of three or four quarts of blood. Green food should be given, and the diet should be attended to as for diabetes. If the urine is scanty, yet evidently Shere is no inflammation, two or three drachms of nitre may be given with the mash at night, but this remedy should be employed with great caution. INACTION OF THE KIDNEYS is so common in every stable that the groom seldom thinks it necessary even to inform his master of its occurrence. An ounce of nitre is mixed and given with a brar- mash as a matter of course, and sometimes more violent diuretica are resorted to, such as powdered resin and turpentine. Very often the kidneys are only inactive because the horse has not been regularly watered, and in those stables where an unlimited supply is allowed this condition is comparatively rare. There is no harn in resorting to nitre occasionally, but if it is often found necessary to employ this drug, the health is sure to suffer, and an alteratier in the diet should be tried in preference. At all events, if it is given, the horse should be allowed to drink as much and as often as he likes, without which the stimulus to the kidneys will be doubly prejudicial, from being in too concentrated a form. DISEASES OF THE BLADDER. THE BLADDER is subject to inflammation of its coats or neck-. to spasm—and to the formation of calculi. INFLAMMATION OF THE BLADDER (cystitis) is not very common. excepting when it is produced by irritants of a mechanical or chemi- eal nature. Thus, when the kidneys secrete a highly irritating urine, the bladder suffers in its passage, and we have the two organs inflamed at the same time. Again, when cantharides have been given with a view to stimulate exhausted nature, or when they are absorbed from the surface of the skin, as sometimes hap- pens in blistering, the bladder is liable to become inflamed. The symptoms are—a quick pulse—pain in the hind quarter, evinced by the looks ot the animal in that direction—and constant strain- ing to pass the urine, which is thick and mixed with mucus, or in ageravated cases with purulent matter The treatment®to be adopted if the case is severe will consist in venesection, back-rak- ing, and purgation with linseed or castor oil, avoiding aloes, which have a tendency to irritate the bladder. Linseed tea should be given as the sole drink, and scalded linseed mixed with a bran- mash as food. The following ball may also be given, and repeated if necessary :— ° Take of Powdered Opiam . <5 = s = «© © 1 Grachm. Tartar emetic ~.. *. ° 1 drachm. To be made up into a ball with Eivaeed Meal and boiling water, and given every six hours. D{SEASES OF TIIE BLADDER, ETC. 89 RETENTION OF URINE may be due either to inflammation of the neck of the bladder, occasioning a spasmodic closure of that part, or there may be spasm unattended by inflamm tion and solely due to the irritation of some offending substance, such as a calculus, or a small dose of cantharides. The treatment in either case must be directed t) the spasmodic constriction, which is generally ander the control of large doses of opium and camphor, that is, from one drachm to two drachms of each, repeated every five cr six hours. If the symptoms are urgent, bleeding may also be resorted to, and when the bladder is felt to be ereatly distended, no time should be lost in evacuating it by means of the catheter, which operation, however, should only be intrusted to a regular practi- tioner accustomed to its use. CALCULI IN THE BLADDER are formed of several earthy salts, and present various forms and appearances, which may be comprised under four divisions. Ist. The mulberry calculus, so named from its resemblance to a mulberry, possessing generally a nucleus. 2d. A very soft kind resembling fuller’s earth in appearance, and being chiefly composed of phosphate of lime and mucus. 3d. Calculi of a white or yellowish color, rough externally and easily friable. And 4th. Those which are composed of regular layers, and which are harder than the second and third varieties. The mulberry calculus, from its extremely rough surface, occa- sions more irritation than other forms, but during life it is impos- sible to ascertain the exact chemical nature of the calculus which may be ascertained to exist. These calculi sometimes attain an immense size, weighing several pounds. The symptoms are a dif- ficulty of voiding ‘the urine, which generally comes away in jerks after creat straining and groaning. The horse remains with his legs extended for some time afterwards, and evidently indicates that he feels as if his bladder was not relieved. Often there is muco-purulent matter mixed with the urine, which is rendered thick and glutinous thereby, but this only happens in cases of long standing. The treatment must be either palliative or curative. If the former, it should consist in the adoption of the means employed for subduing irritation and inflammation of the bladder which have been already described. The cure can only be effected by removing the stone. This requires the performance of a difficult and dangerous operation (lithotomy), the details of which can be only useful to the professed veterinary surgeon, and I shall theree fore omit them here. DISEASES OF THE ORGANS OF GENERATION. BALANITIS, or inflammation of the glans penis (fdAavos, glans), is very common in the horse, being brought on by the decomposi- tion of the natural secretions, when they have been allowed to 9() THE WORSE. collect for any length of time. At first there is merely a slight discharge of pus, but in process of time foul sores break out, and very often fungous growths spring from them, which block up the passage through the opening of the sheath, and cause considerable swelling and inconvenience. These are quite distinct from warts, which occur in this part just as they do in other situations. The treatment requires some skill and experience, because mild reme- cies are of no use, and severe ones are not unattended with danger. The parts must first of all be well cleansed by syringing, or if ‘the end of the penis can be laid hold of, by washing with a sponge. The following wash may then be applied. and it should be repeated every day :-— Take of solution of Chloride of Zine . . « . « 2drachms. WaGOe er ca ae in ht «eee artes Be Mix. If the morbid growths are very extensive, nothing but amputa- tion of the penis or the use of corrosive sublimate will remove them. Severe hemorrhage sometimes follows both of these mea- sures, but it seldom goes on to a dangerous extent. Still it is scarcely advisable for any one but a professional man to undertake the operation. IN THE MARE THE VAGINA Is sometimes inflamed, attended with a copious yellow discharge. An injection of the wash mentioned i, the last paragraph will generally soon set the matter right. At first it should be used only of half the strength, oradually i increas- ing it, until the full quantity of chloride of zine is employed. INVERSION OF THE UTERUS sometimes follows parturition, but it is very rare inthe mare. The uterus should be at once replaced. using as little force as possible, and taking care before the hand is withdrawn, that it really is turned back again from its inverted position. _NYMPHOMANIA occurs sometimes in mares at the time of being ‘in use,” and goes on to such an extent as to render them abso- lutely regardless of pain, for the time being, though not to make thei lose their cousciousness. They will kick and squeal till they be- come white with sweat, and no restraint will prevent them from trying to continue their violent attempts to destroy everything behind them. These symptoms are especially developed in the presence of other animals of the’ same species, whether mares or geldings; but the near proximity of an entire horse will be still worse. If placed in a loose box, without any restraint whatever, they generally become more calm, and when the state is developed, such a plan should always be adopted. It is chiefly among highly- fed and lightly-worked mares that the disease is manifested ; and a dose of physic with starvation in a loose box, away from any other horse, will very soon put an end to it in almost every instance MAD STAGGERS—EP1LEPSY. 91 CHAPTER.

PHRENITIS seldom occurs, except in over-fed and lightly-worked horses, nor-among them is it by any means a common dlis- ease. The early symptoms are generally those of an ordinary cold; there is heaviness of the eyes, with a redness of the con- junctiva, and want of appetite. After a day or two occupied by these premonitory signs, which will seldom serve to put even the most experienced observer on his guard, the horse becomes sud- denly delirious, attempting to bite and strike every one who comes near him, regardless of the ordinary influences of love and fear. He plunges in his stall, attempts to get free from his halter rein, and very often succeeds in doing so, when he will stop at nothing to gain still further liberty. If unchecked he soon dashes himself to pieces, and death puts an end to his struggles. The only ¢reat- ment which is of the slightest use is bleeding till the horse abso- lutely falls, or till he becomes quite quiet and tractable, if the case is only a mild one. Immediately afterwards a large dose of tartar emetic (two or three drachms) should be given, followed in an hour or two by a strong physic ball; or, if the case is a very bad one, by a drench, containing half a pint of castor oil and six or eizht drops of croton oil. Clysters and back-raking will of course be required, to obviate the risk of hard accumulations in the bowels, but where there is great violence, they cannot always be employed and the case must take its chance in these respects. The diet should be confined to a few mouthfuls of hay or grass, with a plentiful supply of water. EPILEPSY AND CONVULSIONS. TMESE DISEASES, or symptoms of disease, are not often met with in the adult. ae in the foal they sometimes occur, and are not unattended with danger. The young thing will perhaps gallop after its dam ronnd and round its paddock, and then all at once stop, 92 THE HORSE. atagger, and fall to the ground, where it lies, struggling with mons or less violence, for a few minutes or longer, and then raises its head, stares about it, gets up, and is apparently as well as ever. It is generally in the hot days of summer that these attacks occur, and it appears highly probable that the direct rays of the sun playing on the head have something to do with it. Death seldom takes place during the first attack, but sometimes after two or tnree repetitions the convulsions go on increasing, and the foal lecomes comatose and dies. A mild dose of linseed oil is the only remedy which can safely be resorted to, and as it is supposed that worms will sometimes produce these convulsive attacks, it is on that account to be selected. Epilepsy is so very rarely met with in the adult and of its causes and treatment so little is known, that I shall not trouble my readers with any account of them. MEGRIMS. THIS TERM is used to conceal our ignorance of the exact nature of several disordered conditions of the brain and heart. In fact, any kind of fit, not attended with convulsions, and only lasting a short time, is called by this name. The cause may be a fatty condition of the heart, by which sudden faintness and sometimes death are pro- duced, or it may consist in congestion of the vessels of the brain, arising from over work on a hot day, or from the pressure of the cullar, or from disease of the valves of the heart. Attacks reputed to be megrims have been traced to each of these causes, and as in every case, the horse, while apparently in good health, staggers and falls, and after lying still for a minutes (during which there is seldom an opportunity of examining the state of the circulation) rises as well as before, there is no chance of distinguishing the one from the other. The most usual symptoms are the following :—The horse is perhaps trotting along, when all at once he begins shaking his head as if the bridle chafed his ears, which are drawn back close to the poll. The driver gets down to examine these facts, and observes the eyelids quivering, and the nostrils affected with a trembling kind of spasm. Sometimes the rest will allow of the attack going off, but most frequently, the head is drawn to one side, the legs of that half of the body seem to be paralyzed, and the horse making a segment of a circle goes down, lies a few minutes on the ground, and then rises as if nothing had happened beyond a light sweating, and disturbance of the respiration. Treat- mené can be of little avail, however, unless a correct diagnosis 1s made, for remedies which would be suited to congestion would be prejudicial to a diseased heart. IPf the attack has kappened while WYDROPHOPBIA. 93 n harness, the collar should always be carefully inspected, and if at all tight it should be replaced by a deeper one. A diseased state of the valves of the heart ought to be discoverable by auscultation, but it requires a practised car to do this, and the directions for ascertaining its presence are beyond the scope of this book. he only plan which can safely be adopted, is to take the subject of megrims quietly home to his stable, and carefully ex- amine into the condition of all his functions with a view to im- prove the action of any organ which appears to be out of order, whatever it may be. If all seems to be going on well—if the appe- tite is good, and the heart acts with regularity and with due force, while the brain seems clear, and the eye is not either dull or suf- fused with blood—nothing should be attempted, but the horse being subject to a second attack, as proved by manifold experience, should be put to work in which no great danger can be appre- kended from them. He is not safe in any kind of carriage, for it can never be known where the fall will take place; and asa saddle- horse he is still more objectionable, and should therefore be put to some commercial purpose, in executing which, if he falls, the only injury he can effect is to property, and not to human life. RABIES, HYDROPHORTA OR MADNESS. ONE REASON ONLY can be given for describing this disease, which is wholly beyond the reach of art ; but as the horse attacked by it is most dangerous, the sooner he is destroyed the better ; and for this reason, every person who is likely to have any control ove1 him, should be aware of the sysaptoms. As far as is known at present, Rabies is not idiopathieally developed in the horse, but must follow the bite of a rabid individual belonging to one or other of the genera canis and felis. The dog, being constantly about our stables, is the usual cause of the development of the disease, and it may supervene upon the absorption of the salivary virus without any malicious bite, as has happened according to more than one earefully recorded case. ‘The lips of the horse are liable to be ulcerated from the action of the bit, and there is reason to believe that in the early stages of rabies these parts have been licked by a dog, the saliva has been absorbed, and the inoculation has taken place just as it would do from any other wound. It is difficult to prove that this is the true explanation of those cases where no bite has been known to have occurred, but as the mouth has in each instance been shown to have been abraded, there is some reason for accepting it as such. To proceed, however, to the symptoms, Mr. Youatt, who has had great opportunities for examining rabies, both in the dog and horse, describes the earliest as consisting 10 “a spasmodic movement of the upper lip, particularly of the angies of the lip. Close following on this, or coutemporancous with it, 94 THE HORSE. are the depressed and anxious countenance, and inquiiing gaze, suddenly, however, lighted up, and becoming fierce and menacing from some unknown cause, or at the approach of a stranger. From time to time different parts of the frame, the eyes, the jaws, par- ticular limbs, will be convulsed. The eye will occasionally wander after some imaginary object, and the horse will snap iain and again at that which has no real existence. Then will come the irrepressible desire to bite the attendants or the animals within its reach. To this will succeed the demolition of the rack, the manger, and the whole furniture of the stable, accompanied by the peculiar dread of water, which has already been described. Towards the close of the disease there is generally paralysis, usually confined to the loins and the hinder extremities, or involving those organs wl ich derive their nervous influence from this portion of the spinal cord; hence the distressing tenesmus which is occasionally seen.” How paralysis can produce tenesmus is not very clear, but of the very general existence of this symptom there can be no doubt. The dread of water, as well as of draughts uf cold air, is also clearly made out to exist in this disease (as in human rabies), and the term hydrophobia will serve to distinguish it better than in the dog, where it is as clearly absent. Whenever, therefore, these symptoms follow upon the bite of a dog, unless the latter is un- questionably in good health, rabies may be suspected, and the bare suspicion ought always to lead to the use of the bullet, which 1s the safest way of killing a violent horse. There is only one disease (phrenitis) with which it can be confounded, and in that the absence of all consciousness and, in milder cases, of fear, so that no moral control whatever can be exercised, marks its nature, and clearly distinguishes it from rabies, the victim to which is con- scious to the last, and though savage and violent in the extreme, is aware of the power of man, and to some extent under his influence. TETANUS—LOCK-JAW. TeTANuS, one form of which is known as lock-jaw, has its seat apparently in the nervous system, but, like many other diseases of the same class, the traces it leaves behind are extremely uncertain, and are displayed more on the secondary organs, through which it is manifested, than on those which we believe to be at the root of the mischief. Thus the muscles, which have been long kept in a state of spasm, show the marks of this condition in their softened and apparently rotten condition. They in fact have had no interval of rest, during which nutrition could go on, and have lost much of the peculiarity of structure which enables them to contract. The stomach often shows marks of inflammation, but as all sorts of violent remedies are employed, this may be due to them rather than to idiopathic disease. The lungs also are generally congested, LOCK-JAW. 95 put here, like the state of the muscles, it may be a secondary effect of the long-continued exertions of the Jatter, which nothing but the absence of all important lesions of the brain and spinal cord would induce the pathologist to pay the slightest attention to. TETANUS may be either idiopathic or symptomatic, but the former condition is somewhat rare. It almost always follows some Gperation, or a severe injury in which a nerve has been implicated. the most frequent causes being the piercing of the sole by a nail, or a prick in shoeing, or the operations of docking, nicking, castra- tion, &e. THE SYMPTOMS are a permanent rigidity of certain voluntary muscles, and especially of the lower jaw (whence the popular name, lock-jaw). The mouth is kept rigidly shut, the masseter muscles feeling as hard as a deal board. One or both sides of the neck are rigid, in the former case the head being turned to one side, and in the latter stretched out as if carved in marble. The nostrils are dilated; the eyes retracted, with the haws thrust for- ward over them; the ears erect and stiff, and the countenance as if horror-struck. At first the extremities are seldom inyolved, but as the disease progresses their control ts first lost, and then they become rigid, like the neck and head. The patient is scarcely able to stand, and plants his feet widely apart to prop himself up, while at last the tail also becomes a fixture. The pulse varices a good deal, in some cases being quick, sinall, and hard, and in others slow and labored. The bowels are generally costive, and the urine scanty; but this last symptom is not so well marked as the state of the bowels alluded to. The treatment should be of a two-fold nature, partly palliative and partly curative. Since the introduction into use of chloroform we have possessed a drug which invariably enables us to remove the spasm for a time, and if it does nothing more, it gives room for other remedies to act and relieve the patient from the horrible tortures which are occasioned by the spasin, while it also allows the muscular and nervous powers to be recruited. When, therefore, a case of tetanus occurs in a horse of any value, an apparatus for applying chloroform (described under the chapter on Operations) should be procured, and tie animal at once placed under its influence. This done, the whole length of the spine snould be blistered with tincture of cantharides, and an active aperient should be given, consisting, if practicable, of a pint of castor oil, and six or eight drops of croton oil. This may be pumped down the throat by the usual syringe and tube, if the front teeth can be separated; but if this cannot be done, some solid cathartic must be selected, though there is often as much difficulty in forcing a ball down as in passing an elastic tube. Failing in either of these, two drachms of calomel, and the same quautity,of tartar emetic should be slightly damped, and placed in 96 THE HORSE. the mouth as far back as possible, in the hope that they may be gradually swallowed; the bowels should be raked, and copious injections of castor oil and turpentine, mixed with several quarts of gruel, should be thrown up. If these remedies fail, nature must be left to her own resources, and they will sometimes be found equal to the task, for many cases have recovered after having been given up «3s beyond the reach of our art. Opium, hexbane, digitalis, hellebor2, and a host of other drugs have been tried, sometimes with, and sometimes without success, and perhaps it is worth while, after the bowels have been well relieved, to give a full dose of one or other of these powerful remedies, such as two drachms of solid opium; but I confess that I think little reliance is to be placed on them, and I prefer the adoption of chloroform every six hours, continued for about two or three hours and gra- dually withdrawn, leaving the cure to the action of the bliste: and purgatives APOPLEXY AND PARALYSIS. Usvuay these are only different degrees of the same disease, but there are exceptions in which the latter is produced by some chronic affection of the spinal cord or brain. As a rule both de- pend upon pressure made on the brain by an overloaded state of the vessels) commonly known as congestion, or by extravasation of blood, in which it escapes from them. APOPLEXY, known among writers of the old school as sleepy stagvers, is not often met with in the present day, owing to the improvement in the management of our stables, and specially to their better ventilation. It is marked by great sleepiness, from which the horse can be with difficulty roused, soon going on to absolute unconsciousness, attended by a slow snoring respiration, and speedily followed by death. The only treatment likely to be successful is copious bleeding, purgation, and blisters to the head and neck. PaRatysts is marked by a loss of power over the muscles of a part, and may be confined to one limb or organ or extend to more. It is a symptom of pressure on, or disorganization of, some pait of the nervous system, and must be considered as such, and nut as a disease of the affected muscles. Thus it requires a knowledge of anatomy to trace it to its seat, without which its treatment would be conducted on false principles. By far the most common form of paralysis is hemiplegia, or paralysis of the muscles of the hinder extremities and loins, generally arising from an injury to the spine. Sometimes the body of a vertebra is broken, and the parts being separated, their edges press upon the spinal cord and produce the disease. At others the vessels within the canal have received a PARALYSIS—STRING HALT. 97 shock, ani the serous membrane secretes (or allows to ooze out) a bloody fluid which presses upon the cord, and produces the same effect but in a more gradual manner. In India, a disease known there as Kumree causes paralysis of the hinder extremities, and is due to inflammation of the membranes, which secrete a bloody serum. In this country, however, paraplegia is very rare except- ing as the result of accident. WHEN A HORSE FALLS in hunting, and never moves his hind legs afterwards, but lies with his fore legs in the position to get up, groaning and expressing great pain and distress, it may be concluded that he has fractured or dislocated his spine and that the case is hopeless. Sometimes, however, after lying for a few seconds, he slowly and with difficulty rises anu 1» ‘ed to a stable, but after two or three hours lies down and cannot be got up again. Here there will be some difficulty in ascertaining whether the mis- chief is confined to a strain of the muscles or is situated within the vertebral canal. If the former is the case the pain is extreme, and generally there will be some quivering cr slight spasm of one or more of the muscles of the hinder extremity, which feel natu- rally firm, while in paralysis they feel soft and are as quiet as they would be after death. By attention to these signs the two cases may be distinguished, but when the case is made out to be true paralysis the treatment is not likely (even if successful in preserv- ing life) to bring about a useful restoration to healthy action. In valuable horses an attempt may be made by bleeding, physicking and blistering, to produce an absorption of the effused serum ot blood, but the recovered animal is seldom worth the outlay, and too often as soon as he is put to any kind of work is subject to a relapse. The most humane and certainly the most economical plan is to put him out of his misery at once by a pistol ball or knife, but if it is determined to try what can be done towards effecting a cure, no better means can be adopted than those I have alluded to. STRING HALT. THIS IS A PECULIAR SNATCHING UP of the hind leg, and is supposed to depend upon some obscure disease of the sciatic nerve. It however is very doubtful whether this explanation is well founded, and there is evidence that in some cases the hock itself has been affected. The extensor pedis seems to be the muscle most severely implicated, though not the only one which is thrown into spasmodic action. No treatment is of the slightest avail. Horses with string halt are able to do any kind of work, but it is considered to be a form of unsoundness. 7 98 THE HORSE. [SUNSTROKE—COUP DE SOLEIL. THIS DISEASE of late years has become of so frequent occar rence, that although not mentioned by previous veterinary writers, it demands a notice from us. The chicf symptoms are exhaustion and stupidity, the animal usually falling to the ground and being unable to go further. TO PREVENT IT, allow the horse at short intervals a few mouth fuls of water, and fasten a wet sponge over the forehead. The sun-shades now used by extensive owners of horses, will go very far in lessening the occurrence of this affection. The following treatment, when attended to at once, in the majority of cases will prove effectual. _ First. Remove the horse from the harness to a cool shady place. Second. Give two ounces of sulphuric ether ; 20 drops of the tincture of aconite root and a bottle of ale or porter as a drench te sustain the vital powers, and to act as a powerful stimulant in equalizing the circulation throughout the body; whilst, 7'hird/y. Chopped ice is to be placed in a coarse towel, cloth or bag, and laid between the ears and over the forehead, secured in any way the ingenuity of the person in charge may suggest. If the levs be cold, bandages will be of advantage. Do not put the horse to work again until he is completely restored. Dumbness is the usual result of sun-stroke—a species of coma—for which there is no vure. Tlorses so affected are of little use in warm weather but are useful in winter.

DISEASES OF THE EAR. DEAENESS is sometimes met with in the horse, but I know-of no symptoms by which its precise nature can be made out; and with- out ascertaining the seat of the disease, it is useless to attempt to treat it. SOMETIMES FROM A BLOW on the external ear inflammation is set up, and an abscess forms ; but all that is necessary is to open it, so that the matter can readily flow out as fast as it forms, without which precaution it will not readily heal. INFLAMMATION OF THE EYE. THIS IMPORTANT ORGAN is subject to three forms of inflamma- tion, to opacity of the lens, and to paralysis of the nerve, called amaurosis. SIMPLE INFLAMMATION is the most common of all the diseases to which the horse’s eye is subject, and it precedes most of the others. It is always the result of any injury of this part, or of eold; and it shows itself if there is a tendency to inflammation of this organ, whenever the horse is in a state of plethora. The symptoms are an intolerance of light, so that the eye is kept half closed, by which it looks smaller than the other; a gummy secre- tion glues the lids together at the angles; the eyelids are slightly swollen, showing a distended state of their veins; and there is more or less watering or overflowing of tears When the lids are separated, their internal surface looks more red than natural, and the white of the eye is covered with a net-work of fine red ves- sels. After the second day the transparent cornea leses its clear- ness, and becomes muddy, sometimes over the whole surface, and at others in specks. If the disease is allowed to go on unehecked, the cornea is involved, and the lining membrane of the aqueous humor follows; a secretion of pus takes place into the chamber, or the cornca ulcerates, and the con‘ents of the eye escape. The ‘ 100 THE MORSE. treatment should ye a copious bleeding from the jugular vein, fol- lowed by a ball, such as— Take of Common’ Physie. Ball . < -... ., ., 2 drachms.

The eye should be bathed with warm water frequently; and, if the mischief be sev re, a seton should at once be put into the skin covering the upper jaw, about two inches below the eye. On the next day, if “the white” still looks red, the bleeding must be repeated; and, if the bowels are much moved, the tartar emetic may be continued without the aloes, while if they are obstinate, the dose of the lat- ter may be increased. When the acute symptoms have somewhat diminished, a camel’s-hair brush may be dipped in wine of opium, and the eye gentiy touched with it daily, which will generally com- plete the cure. The diet must be Jow, corn being forbidden en- tirely, and the stable should be kept very cool and airy. PURULENT OPHTHALMIA is confined to the conjunctiva, and it may be recognised by the profuse discharge of purulent fluid which takes place. The eyelids are much swollen, and the white of the eye is covered with a puffy red membrane, which rises up above the level of the cornea, sometimes in fungoid excrescences. This form of inflammation is generally epidemic, and sometimes runs through a stable without a single exception. The treatment should be, at first, similar to that recommended for simple inflam- mation; but when it reaches the chronic stage, a more powerful stimulus is required to restore the vessels to a healthy condition. A wash composed as follows, must therefore be applied :— Take of Nitrate of Siiver oii ga i ioe, a voll dial coun ta ie eet Distilled Water \.. on; pa, Ay, 3 oe ane ae ae Mix, and drop a little into the eye from a quill daily. Trirts. or inflammation of the iris, generally known as specific ophthalmia, is the most formidable of all the diseases to which the eye 1s subject, and, if not checked, rapidly disorganizes it; while it also, even when renning an unusually favorable course, is very apt to produce opacity of the lens or its capsule (cataract). This pest of the stable is, undoubtedly, often brought on by over stimu- lation, first of the whole body, through the food, and secondly, of the cyes themselves, through the foul emanations from the acc DISEASES OF THE EYE. 101 mulated urine and dung. But these would produce no such effect in a horse, unless he were predisposed to ophthalmia ; and we fina that cattle and sheep are often fed to an enormous degree of obe- sity, in far closer and worse ventilated stalls, without any prejudi cial effect upon their eyes. It may, then, be assumed, that these organs in a horse have a tendency to put on inflammation; but though these words are true they explain nothing of the real cause, and only serve to conceal our ignorance of it. There is another qnestion bearing upon this subject, which is of the highest import- auce. Is the stock of blind horses more liable to blindness than that of sound ones? This has been discussed so often, that it is scarcely possible to throw any fresh light upon it, chiefly because it is so difficult to rely upon the facts adduced pro and con. Blind. ness is often the result of accident, and such cases are believed to be exceptional, and not at all likely to hand down the disease ; but, on the contrary, I am inclined to believe that many of them show a marked tendency to its development; for an accident never destroys both eyes, and when one follows the other, it is a pretty sure sign that there is a tendency to ophthalmia. On the whole, it may, I think, be assumed, that the tendency to specific ophthalmia is handed down from generation to generation, and, consequently, that the offspring of a horse who has gone blind from that cause Is peculiarly prone to it. Its symptoms appear very rapidly, the eye having been quite right over night, looks contracted and almost closed next morning, and on inspecting it closely “the white’ looks of a deep red, the cornea looks muddy, and the colored part of the eye (the iris) has lost its bright color, and often shows one or two white specks upon it (these must not be confounded with specks on the cornea). As the disease advances, the intolerance of light is very great, the cornea and iris become gradually more muddy, and either lymph is thrown out on the latter in the shape of white patches, or pus ‘s secreted and fills the chamber of the aqueous humor, in part or whollv. If the treatment 1s sufficiently energetic, these signs abate, the pus or lymph is absorbed, and the eye recovers its trans- parency ; but there are generally some traces left behind. Bleed- ing (either from the jugular or the angular veins of the face), moderate purging, and a seton, are the remedies best calculated to effect this object, conjoined with an airy stable and a light diet. Unfortunately, however, iritis is almost sure to return on the restoration of the usual food, and exposure to the elements ; and hence it is of the utmost consequence in purchasing a horse ta examine his eyes for the marks lett behind by it. If the case 1s hopeless, it becomes a question whether or not it will be wise te put an end to the inflammation by destroying the affected eye, for it is well known that if it goes on for any length of time the other, sound eye, becomes affected. The only difficulty consists in feel- 102 THE HORSE. ing assured thal, there is really no chance of recovery; for when once the eye is finally condemned, the sooner it is opened and its contents evacuated, the sooner will the horse return to his work, and the more chance has the other eye of escaping. The operation is very simple, and merely requires a sharp-pointed knife to be passed into the anterior chamber from one edge of the cornea, and driven hack till it cuts into the lens, when it is to be brought out on tha other side uf the cornea, and the whole of the humors will escape on making pressure upon the upper eyelid. In INJURIES of the eye, fomentation with warm water should be carried on for half an hour, and then omitted for three or four hours; after which it may be repeated again and again, at similar intervals. Great care should be taken to remove any extraneous bodies, such as particles of dust, &c. CATARACT, or opacity of the lens, is very commonly the result of iritis, its capsule having been coated with a layer of white lymph, deposited by the inflamed vessels; but it also sometimes makes its appearance without being preceded by any of the signs of inflam- mation. In the former case, the early symptoms are those of iritis ; but in the latter, the opacity often goes on increasing, without the owner of the horse, or his groom, having his attention drawn to the eyes, until he finds that he is nearly blind. This progress is generally marked by the development of an unusual timidity; the previously-bold animal is alarmed at objects advancing on the road, and covered carts and wagons, of which he formerly took no notice, vecasion him to shy in the most timid manner. On examining his eyes carefully, instead of the beautifully clear pupil, with the re- flection of tapetum lucidum shining through it, there is seen either amass of dull white, generally more opaque in the centre, or an appearance of mottled, semi-transparent soap, or, lastly, one or two distinct white spots, not quite circular, but with irregular edges. In confirined cataract, the white pupil can been seen at any dis- tance; but in the very early stage, only a practised eye can detect the opacity, which, however, is so manifest to him that he wonders it is not visible to every one else. The reason of this difficulty of detecting the alteration of structure seems to be, that inexperienced examiners look at the eye in such a manner that they are confused by the reflection on it of their own faces, hiding all beneath. If, however, they will turn their heads a little more on one side, this wil. disappear, and they cannot fail to perceive the disease. When eataract is clearly proved to exist, all idea of treatment may be abandoned, as nothing but an operation can procure a removal of _ the opacity ; and that would leave the horse in a more useless con- dition than before, since he could see nothing clearly, and would only be subject to continual alarms. In the human being, the operation is performed with great success, becausc the lens whi zh. AMAUROSIS—BUCK EYE. ‘ 103 {a sacrificed can be replaced externally by means of convex glasses , but in the horse, nothing of the kind can be done. Hence, it 1a useluss to dream of effecting any improvement in this disease; and if both eyes are the subject of cataract, the horse is incurably blind. But supposing there is a cataract in one eye only, is the other sure to go blind, or may a reasonable hope be entertained of ifs remaining “sound? Here the history of the disease must be examined before any opinion can be formed If the oracity ful lowed an accident, there is no reason for concluding that the othes eye will become diseased; but if it came on idiopathically, either preceded by inflammation or otherwise, there is great risk of a repetition in the sound eye. Nevertheless, instances are common enough of one eye going blind from cataract, while the other re- mains sound to the end of life; and those are still more frequent in which the one sound eye continues so for six or seven years. AMAUROSIS. Tits 18 A PALSY of the nervous expansion called the retina, produced by some disease, either functional or organic, of the optic nerve, which is generally beyond the reach of our senses, in ex- amining it after death. The symptoms are a ful] dilatation of the pupil, so that the iris is shrunk to a thin band around it, and is so insensible to the stimulus of light, in confirmed cases, that, even when the eye is exposed to the ‘direct rays of the sun, it does not contract. In the early stages, this insensibility is only partial ; and though there is such complete blindness that the horse cannot dis- tinguish the nature of surrounding objects, yet the pupil contracts slightly, and the inexperienced examiner might pass the eye as a sound one. The unnaturally large pupil, however, should always create suspicion; and when, on closing the lids and re-opening them in a strong light, there is little or no variation in its size, the nature of the disease i is at once made apparent. The treatment of amaurosis must depend upon the extent to which it has gone, and its duration. If recent, bleeding and a seton in close proximity to the diseased organ will be the most likely to restore it. Some- times the disease depends upon a disordered condition of the sto- mach, and then a run at grass will be the most likely means to restore both the affected organs to a sound state. Generally, how- ever, an amaurotic eye in the horse may be considered as a hope- Jess case. BUCK EYE. A BOCK EYE is, strictly, rather a congenital malformation than a disease ; but practically, in reference to the utility of the animal, it matters little. It depends upon an excess of couvexity in the eorneay by which the focus of the eye is shortened too much, the image being thus rendered indistinct as it falls on the retina. Nu treatment cau be of the slightest use. 104 THE HORSE. SURFEIT. AN rRuPTION of the skin, which shows itself in the form of humerous small scabs, matting the hair, and chiefly met with on the Joins and quarters, is known by this name. Doubtless, it has been supposed to arise from an excess of food, causing indigestion ; bu: it often comes on in horses which, apparently, are quite free from that disorder. The most common cause appears to be, sweat- ing the horse when he is in a gross or plethoric condition, and then exposing him to a chill. Colts are very subject to surfeit while being broken, as are horses fresh from grass during the summer, when they are usually over-fat, and require great care in reducing this plethorie condition. The usual course of the eruption is for the scabs to dry and gradually loosen, when the hair of the part is slightly thinned by being pulled out in dressing, a fresh crop of pustules forming, and, to the casual observer, keeping up the ap- pearance of a permanent state of the original scabs. Surfeit is not confined to gross horses, as it sometimes makes its appearance in those which are low in condition, exhibiting the same appear- ance to the eye; but, on examination, the secretion from the skin will be found to be thinner, and of a more purulent nature. The treatment must greatly depend upon the state of the general health. If the horse is very gross, it may be desirable to take a little blood away; but this will ‘seldom be necessary. and never is desirable. Physic seems to do little immediate good; and, indeed, it is very doubtful whether any treatment is of much service, excepting such as will gradually bring the horse into working condition. The disease, in most cases, has its origin in obstruction of the seba- ceous and perspiratory pores; and until these are restored to their proper functions, by gradually exercising them, little good can be done. Unfortunately, the very means which will accomplish this object are apt to increase the disease for a time; but still this must be put up with, as a matter in which no choice can be made. Regular exercise and grooming must be fully attended to, using the whisp only in dressing the skin, when the eruption shows itself, and carefully avoiding the brush and currycomb. By acting on the kidneys, mure eood will be done than by purging physic, which seems to be of little or no service in any case but when the stomach is greatly out of order. An ounce of nitre may be given with a mash twice a week, or the following balls may be ad- mil.istered :— Tuke of Nitre, itl PMU, Ol CHON” res. co, ei ot ee ee eee 83 drachms.

THIS {8 ESSENTIALLY a disorder of the skin produced by sym- pathy with the stomach. It rarely occurs in any horse but one sadly out of health from a deficiency either in the quantity or quality of the food. Sometimes it comes on in the latter stages of consumption or dysentery, without any previous mismanagement; but in the vast majority of cases the cause may be laid to the food. The skin of a horse in health feels supple, and on his sides it may readily be gathered up by the hand into a large fold, but in hidebound it is as if it were glued to the ribs, and were also too tight for the carcase which it invests. The name, indeed, is expressive of this state, and the disease can scarcely be mistaken when once seen, or rather felt. Coincident with this condition of the skin, there is also, generally, either a distended state of the abdomen from flatulence, or a contracted and “tucked up” appear- ance from diarrhoea. The treatment should be addressed to the digestive organs, the state of which must be carefully examined, and if possible rectified. A pint of linseed, scalded, and mixed with a bran mash every night, or scalded malt given in equal quantities with the corn; or in the spring time, vetches, clover, or lucerne, will do more than any medicine; but when there is a deficient appetite, or the bowels or stomach, or either of them, are evidently much weakened and disordered, a stomachic ball once or twice a week will do good. The remedies appropriate to these several conditions will be found under their respective heads at pages 304, and 363, 364. MANGE. MANGE corresponds with the itch of the human snbject in being produced by a parasitic insect, which is an acarus, but of a different species to that of man, and of a much larger size, so as to be readily visible to the naked eye. It is generally produced by contact with horses previously affected with the same disease, but it appears highly probable that a poor, half-starved animal, allowed to accumulate all kinds of dirt on his skin, will develop the para- site, though how this is done is not clearly made out. The whole subject of parasites is wrapped in mystery, which modern researches appear likely to fathom, but hitherto little progress has been made except in the history of the metamorphoses of the tape-worm, from the analogy of which some idea may be formed of the prob- able modes of production of other parasites. When caused by contagion, as certainly happens in the vast majority of cases, the first symptoms noticed will be an excessive itching of the skin, which is soon followed by a bareness of the hair in patches, partly eaused by constant friction. The disease usually sl.ows itself on 106 THE HORSE. the side of the neck, just at the edges of the mane, and on the insides of the quarters near the root of the tail. From these parts the eruption extends along the back and dovn the sides, seldom involving the extremities excepting in very confirmed easez. After a time the hair almost entirely falls off, leaving the skin at first bare and smooth, with a few small red pimples scat tered over it, each of which contains an acarus, and these are con- nected by furrows, along which the acari have worked their way to their present habitation. In process of time the pimples increase in number and size, and from them a matter exudes which hardens into a scab, beneath which, on examination, several azari may readily be seen, moving their legs like mitcs in a cheese, to which they are closely allied. At first the mangy horse may keep his health, but after a time the constant irritation makes him feverish ; he loses flesh, and becomes a most miserable object; but such cases of neglect are happily rare in the present day. he treatment must be addressed to the destruction of the lite of the acarus, which, as in the human subject, is rapidly destroyed by sulphur, turpentine, arsenic, hellebore, and corrosive sublimate. Some of these drugs are, however, objectionable, from being poisonous to the horse, as well as to the parasite which preys upon him, and they are, therefore, not to be employed without great and urgent necessity, in consequence of the failure of milder remedies. |The following recipes may be relied on : perfectly efficacious, the former being sufficient in mild cases, and the latter being strong enough in any. 1.

One or other of the above dressings should be well rubbed in every third day for at least three or four weeks in bad cases, and two in trifling ones, when the inflammation resulting from the avari and also from the application may be allowed to subside in the hope that all the parasites are killed, in which case the erupe tion disappears, but the hair does not always come on again as thickly as ever. All the stable fittings around the stall or box in which the horse has been standing should be thoroughly washed over with a solution of corrosive sublimate, made as follows :-= MANGE—LICE—MALLENDERS, ETC. 107 Take of Corrosive Sublimate . . . . » 1 oz.

IN FORMER DAYS LICE were not uncommon in the horse, but they are now comparatively rare. Still they are occasionally met with, and their presence is readily ascertained, being of a consi- derable size, and easily seen with the naked eye. They may be destroyed by rubbing into the roots of the hair white precipitate, in powder, taking care to avoid sweating the horse or wetting his skin for some days afterwards. MALLENDERS AND SALLENDERS. THESE ERUPTIONS are both of the same nature, differing only in the locality where they are displayed. The former shows itself in the flexure at the back of the knee, and the latter at the bend of the hock. The symptoms are shown in the appearance of a foul scurf mixed with a few thin scabs, the skin underneath being stiff and unyielding. They are generally brought on by washing the legs and leaving them undried. The treatment required is merely - the application of the following ointment, which should be well rulbed in every night :— Take of Cerate of Superacetate of Lead . 2 2.

WHEN THE SADDLE HAS GALLED the skin beneath it, the ja- 108 THE HORSE. flammation resulting is called a “warble,” and if this is neglected, so an t) cause a troublesome sore, the term ‘‘sitfast” is applied. The effect produced is similar to a harness gall, and there is not the slightest necessity for inventing names to distinguish each stage of cruelty in the rider, for if attention is paid to the warble no sit- fast will ever m: ke its appearance. Prevention is better than cure, and it may almost always be effected by the adoption of the plan of always keeping the saddle on (after loosing the girths) for a quarter of an hour or twenty minutes. Sometimes, however, in spite of this precaution, the skin of the back swells, and when a heavy man has been riding for six or eight hours on a horse unac- customed to his weight, the cuticle will perhaps peel off, bringing the hair with it. When the swelling is considerable it should be well fomented for an hour, and then bathed with a lotion composed of one drachm of tincture of arnica in half a pint of water. The saddle should never be re-applied until the skin is quite cool and free from all inflammation, even if considerable inconvenience is thereby suffered. The same treatment will also apply to harness galls. Oiling the inside of the collar will often prevent the shoulder from suffering excoriation. GRUBS. THE LARVA OF SOME BEETLE, but of what species I do rot know, is occasionally met with in the horse, causing a small luinp, about the size of a raisin, and usually on the back. This obsti- nately continues for months, if its nature is not understood, in spite of all ordinary applications. At last a white larva or grub, with a black head, and very similar in everything but size to the maggot found in the nut, makes its appearance, and either escapes to fall on the ground and become a chrysalis, or else it is squeezed out by the groom, which is easily done as soon as the head is visi- ble. When discovered previously, an opening may be made with the point of a penknife, and then the larva may be gradually squeezed out. avoiding too much haste in the operation, which will only retard the process. BITES AND STINGS OF INSECTS. IToRSES ARE IIABLE TO BE STUNG by hornets, wasps, and bees. Ii there are only one or two stings made, no interference is neces- sary; but sometimes a larger number of poisonous puvctures have been effected, and then the best treatment is the application of spirit of turpentine and laudanum in equal proportions. THE BITES OF THE GADFLY are so troublesome in their effects that it is sometimes desirable to prevent them if possible. This is effected by making a strong infusion of the green bark of the elder, end washing the flanks, &c., with it before going out. SWELLED LEGS. 109 SWELLED LEGS. THE SKIN OF THE LEGS AND THE CELLULAR MEMBRANE be. neath it are liable to two kinds of swelling, one of which is of an infiammatory character, while the other is solely due to a deposit of serum (cedema), owing to the non-performance of their office by the kidneys. Both kinds are much more frequent in the hind legs than the fore, but especially the former. — INFLAMMATORY SWELLED LEG, sometimes called weed, is gene- rally accompanied by a certain amount of feverishness, and comes on suddenly, almost always showing itself on the inside of the hind lez which is hot and extremely tender. It is not a very common disease, and merely requires the ordinary low treatment, by purging physic, and, if necessary, bleeding. Should it continue for more than two or three days after these are tried, an ounce of nitre may be given every night in a bran mash. ORDINARY SWELLING OF THE LEGS, OR @DEMA, occurs in every degree, from a slight ‘filling,’ to which many horses are always subject, whether they work or stand in the stable, to an enlarge- ment extending up to the stifles and elbows, sometimes rendering the legs almost as round and as hard as mill-posts. When horses are first brought in from grass their legs almost always fill more or less, and until they are regularly seasoned to their work there is seldom that clean condition of the suspensory ligaments and back sinews which one likes to see even before the daily exercise is given. The oedema appears to depend partly upon a deficient action of the kidneys, but chiefly on the vessels of the legs not acting sufficiently without constant walking exercise, such as is natural to the horse when at liberty, and which he takes at grass. Half an hour’s walk- ing will generally produce absorption completely, so that a daily remedy is forthcoming; but asa rule, whenever there is this ten- dency to ‘filling’ of the fegs, the cellular membrane is not the only tissue in fault, but the tendons and joints are also liable to inflammation. The treatment will greatly depend on the exact eause. If the swelling is only due to the change from grass to the confinement of a warm stable, time alone is wanted, taking care not to overwork the horse in the mean time. Bandages will always assist in keeping down the swelling; but they should not be used without necessity, as when once the horse becomes accustomed tu them his legs can hardly be kept fine without their aid. If weak- ness is the cause, a drachm of sulphate of iron given in the corn twice a day will often strengthen the system, and with it the legs. Diuretics may be adopted as an occasional aid to the kidneys, but they should be of the mildest kind, such as nitre, or they will do more harm, by: weakening the body generally, than good by their stimulus to the kidneys. Indeed, they are often the sole cause of 110 THE HORSE. the legs filling, for some grooms use them so continually, whether they are wanted or not, that the kidneys become diseased and refuse to act, which is a sure forerunner of oedema. Where swelling of the legs is confirmed, bandages must be regular’7 applicd as recom- mended at page 196. CHAPPED HEELS. WHEN A HORSE SUFFERS FROM CDEMA Of the legs, he is par ticularly prone to an eruption of a watery nature in the cleft between the heels and behind the lesser pastern, Those also whose legs are washed and not dried are still more prone to it, especially if the hair is white. The skin cracks, and, in bad cases, 1s so inflamed and swollen that the leg cannot be bent without great pain, and often there is a bleeding from the cracks, caused by the action of the limb, but only to a sufficient extent to show that blood has escaped. The treatment must be local as well as general if the eruption is not entirely due to mismanagement. In any case, the part should be dressed with cerate of acetate of lead, a little of which should be rubbed in every night. Next morning some gly- cerine should be brushed on an hour at least before the exercise, and renewed before the daily work is commenced. This will pre- vont all risk of the skin cracking, while the ointment will act bene- ficially on the vessels of the part. ._In addition to these applica- tions, the general health should be attended to if in fault, and tonics or diuretics should be given, as the case may require. GREASE. TNE ERUPTION KNOWN AS GREASE is sometimes only an agera- vated form of chapped heels, and is often preceded by them. At others the appearance of the disease is ushered in by constitutional symptoms, such as feverishness, oedema of the limbs and hide- bound. The first local symptom is a slight swelling of the skin ot the heels and adjacent parts, which soon cracks, and from the fissures there exudes an offensive discharge which looks greasy, but is really watery, being of a scrous nature. It inflames every part that it touches, and has a tendency to cause a spread of the eruption © tn all directions, but chiefly downwards. The legs go on swelling to a frightful extent, and are thereby rendered so stiff and sore that great lameness is produced. If this stage is neglected the whole surface ulcerates, and a fungous growth makes its appearance, chiefly from the original cracks. The discharge becomes purulent aud has a most foul smell, and the leg ean with difficulty be bent at all. nally, the fungoas exerescences cover the whole of the diseased skin, being of a bright red color, and slightly resembling grapes in form, from which circumstances this stage has been GREASE, OR SCRATCHES. Tt called ‘the grapes.” It is now very rare to mect with grease In any of its forms except in the eart-stable, where the hairy legs of its inmates render them peculiarly prone to its attacks, from the time required to dry them when wet. They are so difficult to clean without water that the carters may well be excused for using it, but if they do they ought carefully to dry the legs afterwards. The treatment when grease is established must be founded upon the same principle as in chapped heels. The skin must be kept supple, and at the same time stimulated to a healthy action. For the former purpose glycerine is most valuable, being far more effi- cacious than any greasy dressing, such as we were obiiged to employ before the discovery of this substance. In all the stages of grease, this latter agent may be employed, and as it is readily soluble in water it can be washed off and renewed as often as it may be desired. The discharge is so foul and irritating that it ought to be thoroughly removed at least once in twenty-four hours, and one of the chief advantages of the use of glycerine is that it so greatly assists this cleansing process from its solubility in water. In addition to this emollient plan, some stimulus must be selected, and none answers so well (in all stages but the very earliest) as chloride of zine. When, therefore, the heels are in that state that it is almost doubt- ful whether the disease is the mere chap or absolute grease, the trentment recommended for the former may be tried, but should this fail, the groom should at once proceed to cut the hair of the skin which is diseased as short as possible. Then let him take some soap and warm water and gently wash the parts with a sponge till the skin is perfectly clean and free from scab or scurf, taking care to remove every particle of soap by well rinsing it. Next dry the lez, and then with a small paint-brush rub gently into the in- flamed parts enough of the following lotion to damp them, but not to wet them thoroughly :— Take of Chloride of Zinc . « «© © © © © » © SO grs. Water e e ° s J s e se e e s e 1 piut. Mix. A quarter of an hour afterwards apply a little glycerine over the whole, and keep the parts sufficiently supple with it. If there is much discharge the cleansing may be repeated night and morning, followed by the chloride of zinc, but in most cases once a day will be sufficiently often. If the ulcerated or inflamed skin does not put on a healthy appearance in a few days, the lotion may be in- creased in strength, using forty, fifty, or sixty grains to the pint, as required; but the remedy will be found to be almost a specific. ex- cept for the grapy form, if properly proportioned in strength. When the fungoid growths are very extensive, nothing but their removal, either by the knife or by the actual or potential cautery, will suffice. The least painful plan is to slice them off to a level with the skir Tt? THE HORSE. and then just touch the bleeding surface with a hot iron, which will have the double good effect of stopping the bleeding and in- ducing a healthy action. ‘The glycerine may then be applied, and next day the leg may be treated in the same way as for ordinary grease described above. When the disease is of long standing local applications may cure it for a time, but either it will return, or there will be some other organ attacked, unless the unhealthy wtate of the blood is attended ‘o. It must be remembered that during the existence of grease this vital fluid is called upon to supply the materials for the secretion which is constantly going on. Now if on the cessation of the demand for them the blood still goes on obtaining its supplies from the digestive organs, it becomes overloaded, a state of plethora is established, which Nature attempts to relieve in some one or other of her established modes by setting up disease. To avoid such a result arsenic may be given internally, for this medicine has a special power in counteracting this ten- dency. How it acts has never yet been made out, but that it does exert such a power is thoroughly ascertained, and if the doses are not too large it is unattended by any injurious effect. Indeed for a time it seems to act as asa tonic. ‘The arsenic should be given in solution and with the food, so as to procure its absorption into the blood without weakening the stomach. 172 THE HORSE. 60.

GREASE, and GLANDERS. MANGE. MxrGrRIMSs, when the attack comes on subsequently to the sale, and can be shown to have occurred before it. A NERVED HORSE is unsound from the existence of the disease for which the operation has been performed, as well as from the division of the nerves. OrnTHALMIA, if it can be proved to have previously existed, and comes on soon after the purchase, is to be received as unsound- ness. So, also, when any of the evidences of its previous presence can be detected, and are proved by a veterinary surgeon, the horse is returnable. OssIFICATION of any of the structures adjacent to the joints is unsoundness, and hence ossification of the lateral cartilages will be considered so, without doubt. PUMICED FOOT, as evidence of laminitis. QUIDDING. QUITOR. RINGBONES, and SIDEBONES, whether large or small, are un. doubtedly sufficient to constitute a horse unsound.

THICK WIND, as marking some impediment to respiration. THRUSH, when it is in one of its severe forms, and not caused by mismanagement. THICKENING OF THE BACK SINEWS, or suspensory ligament, when existing to any extent easily appreciable, is to be received aa a proof of unsoundness.

WEAVING in the stable WHEN A HORSE IS PURCHASED with the conditions that he is warranted sound, or free from vice, or quiet to ride and drive, the warranty must either be in writing, or given in the presence of a disinterested third person. The form of warranty is as follows, and ‘+ is better that it should be on the same paper as the stamped receipt, though this is not absolutely necessary if it is shown that the receipt is preperly given. Date. Received of A. B. C. fifty pounds for a bay gelding, by Small- hopes, warranted five years old, sound, free from vice, and quiet to ride and drive. 500. x: VK Any one or more of these points may be omitted, or the horse may simply be warranted “a good hack,” in which case he must fairly answer that description. The terms “ has been hunted,” or “ has carried a lady,” are not to be trusted, as it is only necessary to prove in defence that the horse has seen hounds, and had a woman on his back. WHETHER THE HORSE UNDER EXAMINATION is to be wars ranted or not, the intending purchaser should never omit to look over every point where unsoundness is likely to occur. ‘To do this effectually it should be done regularly, by which there is less chance of passing over any serious defect. The usual mode of proceeding is as follows. Under no circumstances, if it can possibly be avoided, should the horse be looked at immediately after having been out of doors; and if he is of necessity brought to the purchaser, let him be put in the stable and quietly rested for one or two hours at the least. by which time the effects of most of the “coping” tricks will s.ave gone off. BEFORE THE HORSE PASSES THE STABLE-DOOR, stop him with Lis head just inside, and in that position carefully examine his eyes. The light is exactly suited to this, and the sensibility of the iris may be well judged of. Any specks or opacities are also here readily seen. ‘Then let fim be led toa level surface, and then pro- ceed to look over every part, beginning with that nearest the one already inspected, namely, the mouth, Then “cough” him by tightly grasping the larynx, by which some idea may be formed of 184 THE HORSE. the state of his respiratory organs, after which the usual manoeuvre with the stick may be practised if there is no opportunity of ex. amining into his freedom from roaring in the saddle. When these points are satisfactorily disposed of, look to the position of the fore legs, that is, whether they are turned in or out, and if the latter feel the elbows, and see if they are confined or “tied,” that is too close to the ribs, also look for marks of cutting and speedy cutting. Pass the hand down the back sinews and suspensory ligaments, ex- amine the knees for any marks, and then carefully feel the coroneta and heels for any marks of exostosis or ossification. Lastly, take a good look at the front of the foot, and then lifting it inspect the frog, heels and sole. This will complete the front half uf the body, after which the form of the middle and loins should be regarded, and then, lifting the tail, the openness or otherwise of the space round the anus will give some idea of the strength of constitution, while the resistance afforded by the dock will be a sign of the mus- cular strength of the back. Then look carefully at the hocks, ex- amine the spavin and curb places, and finish the whole by passing the hand down the hind cannon bones to the fetlocks, and feel them in the same order as in the fore legs. Now let the horse rest a minute if his groom will let him, with his head quite at liberty, and you will be able to judge of his ordinary habit of standing, when unexcited. At the conclusion of this careful examination while at rest, the action must be as minutely investigated, by first having the horse walked with a loose vein, and then trotted in the same way slowly, when if he is sound he will put his feet down rezularly and firmly. Grooms, when they want to conceal defects, will not let the head be loose, nor will they trot slowly, but bustle the horse along with their hands as close as possible to the mouth, s0 as to prevent any nodding of the head as much as they can. A very geod judge will be perhaps able to select a pleasant pack or harness horse by seeing him thus run, and afterwards ridden, but a far better test is to ride or drive him yourself, when his freedom from vice, or disease, may be ascertained, as well as his manners, and the ease of his various paces. No trouble should be spared to get this real trial, which is worth ten per cent. on the purchase- money, for many a horse which /ooks to go well does not fee/ so, and it is well worth that sum to be saved the trouble attending upon the possession of a horse which does not su't. When, however, after such a careful examination by a competent judge, and subsequent trial in the saddle or in harness, the horse is fourd to be really likely to answer all the purposes for which he is wanted, a few pouuds should never prevent his being obtained.
