The foot is thus sectionised and described by Delaware P. Elaine, Esq.:—

“On examining a perpendicular section of the foot and pasterns, there appear the coffin-bone (a), the navicular or nut bone (b), the coronary or little pastern bone (c), the large pastern bone (d), the back sinew or great flexor tendon of the foot (e), the same tendon sliding over the navicular bone (f), its termination or insertion into the bottom of the coffin-bone (g), the elastic matter of the sensible frog (h), the insensible or horny frog (i), the horny sole (k), which includes the parts of the sensible foot; the outer wall of the hoof (l), the elastic processes (m), the attachment of the extensor tendon to the coffin-bone (n), and its attachment to the coronary bone (o), which completes the section.

“The coffin-bone (a) adapts itself to the figure of the hoof, or rather is adapted by nature to this eligible form. The eminence in its front receives the insertion of the tendon of the great extensor muscle of the foot. This important muscle has its upper attachment to the humerus or arm-bone, where it is principally fleshy; but as it passes downwards it becomes tendinous, expanding over every joint, both to prevent friction and to embrace and give firm attachment to each bone with its opposed bone, by which a firm connection of the various parts is maintained, and a simultaneous movement of the whole limb is effected. In the hinder limb this extensor tendon and its two less or tendinous adjuncts arise from the tibia, and in part from the femur, but in their origin are fleshy.

“In the sides of the coffin-bone are attached lateral cartilages, and around its surface are marks of the attachment of the laminated substance.

“The coronary, or small pastern bone (c), is seen to rest on the coffin-bone (a), with which it articulates by its lower end; its posterior part also may be seen to be closely articulated both with the coffin and with the navicular or nut bones (f), whose attachments to them are effected by ligaments of great power and some elasticity. Nor is it possible to view this horny box and its contents without being struck with the admirable display of mechanism and contrivance which meets our eye. We are apt to say, ‘as strong as a horse,’ and some of us use horses as though they were made of imperishable stuff; but surely, when we well consider the subject, we shall see both the necessity and the morality of using them with discretion.”

This description of the structure of the foot will probably better enable the uninitiated to understand the seat and nature of various ailments of that part of the horse which are here touched upon.

Blaine further describes the construction of the hoof thus:—

“The hoof itself is conical, or rather, as Clark observes, slightly truncated, and is a secretion as well from the vascular parts of the foot as from the skin, as our nails are formed from the portion of skin called quick. The structure of the hoof is firm and fibrous. Externally it is plane and convex, but internally concave and laminated. The quarters are the lateral parts. As the horn approaches the heels it becomes soft and is reflected inwards. The heels are parted by the horny frog (b, fig. 3); and without, the frog on each side the hoof inflects its fibres to form the bars which are seen on the under surface (c, fig. 4). In a healthy foot, fig. 4, the heels are round, wide, and smooth (a, a), the frog fully expanded, the bars or binders distinct (c, c), no corns in the usual angle (d), the sole broad and concave (d). In a diseased foot, fig. 3, the heels are high, and drawn together by contraction (a, a), the frog narrow, and filled with fissures from contraction and thrush (b), corn frequently present (d), the sole greatly shortened in its transverse diameter, which is morbidly counterbalanced by the increased heights in the truncated form (c). When the hoof is removed, the sensible or fleshy sole (h, section of foot), above which it immediately lies, presents itself, covering the whole of the horny sole, except so much as is taken up by the sensible frog (h). This part is exquisitely sensible and vascular, and thus we learn why injuries to it from puncture produce such serious effect, and why very slight pressure from contraction of the hoof gives so much pain. The sensible frog and the sensible sole form the insensible frog and sole; but when from pressure, too much moisture, or other causes, the sensible frog, instead of forming horn, secretes pus or matter as in thrush, the structure of the whole becomes injured, and the frog, thus losing its support, gradually wastes and decays. It is therefore evident that no thrush can be entirely harmless, as is erroneously supposed.

“Above the sensible frog is the great flexor tendon, or back sinew, inserting itself into the vaulted arch of the coffin (a, section of foot). This important tendon, arising from its parent muscle above the knee, whose origin is taken from the humerus and ulna, in its passage unites with an assistant flexor, but which latter is principally distributed to the pastern bones, while the perforans, so called because it is perforated by the assistant flexor tendon, is inserted into the vault of the coffin; in the posterior extremities the attachments of these two leading flexors and a smaller lateral one are from the femur and tibia.

“The Sensible LaminÆ.—Around the surface of the coffin-bone, it has been noticed that there are linear indentations to which about five hundred fibro-cartilaginous leaves are attached. Each of these is received between two of the horny lamellÆ, which line the interior of the horny hoof; and when it is considered what a vast surface of attachment is formed by these means, the strength of the union will not be wondered at. No common violence can separate these parts, and their use as a spring (for they are extensile) to support the action of an animal at once weighty, strong, and extremely agile, must be apparent.

“The vessels and nerves of the foot are derived from the metacarpal arteries, veins, and nerves, which pass behind the pastern, when the main trunks divide to proceed to each side of the foot, and are ramified from thence throughout. It is a division of the metacarpal nerve on each side of the lesser pastern, or on each side of the larger, as occasion suits, which forms the nerve operation now in vogue as a remedy (?) for navicular disease.”

Laminitis, or Fever of the Feet, although generally the result of too long a journey, or any exercise where excessive and continuous concussion has been occasioned to the feet, frequently arises from other causes. It is often what is termed secondary, as one of the sequelÆ of inflammatory diseases of a more constitutional character.—(See “Metastasis,” page 155.) The laminÆ are plates (technically, semi-cartilaginous leaves received between the horny lamellÆ which line the interior of the hoof) resting on the inside of the horny hoof, and giving an elastic support, whereby the whole weight of the horse’s structure is thrown against the wall of the hoof and kept off the side. It is not surprising, therefore, that these causes should produce derangement here.

As laminitis generally attacks the fore feet, the poor beast in his anguish endeavours to throw his weight off them by resting on his hind quarters, which are tucked under him, with the fore legs and feet pushed out before him merely to keep him from falling; he can barely hobble if he attempts to move. If the fever be only slight and in one foot, he will point it, while extreme lameness and unnatural heat in the foot mark the disease. The shoe should (in this as in all cases of foot-lameness) be instantly removed by a smith brought to the stable instead of giving the poor creature the pain of limping to the forge.

The foot should be put into cold water, constantly renewed, and kept in it all day; at night a bran poultice or water-dressing should be left on (see “Water-dressing” and “Poultices,” page 160). Also administer a purge.

In acute cases, bleeding at the toe is sometimes practised by paring away there till the veins appear. This is a very questionable remedy, and there is little doubt that the use of the knife only aggravates the inflammation.

The fact is, that beyond its incipient stage none but the veterinary surgeon is competent to deal with this disease.

Its prevention is best secured by requiring moderate work only, and at the proper road-paces—viz., walking and trotting—keeping the feet moist, wetting them occasionally during a long journey, and regularly stopping them directly after each day’s severe work.—See “Grooming,” page 12.

Navicular Disease is, unfortunately, a very common one with horses; and when the delicate structure of the foot is considered in connection with the rough usage the creature gets on hard roads while carrying a heavy weight on his back, it is only surprising that the feet bear such jarring at all.

The navicular is the small pulley-bone over which the flexor tendon passes, and being the most active of any of the foot-bones, is the most likely to be injured by ill usage (see page 128). The symptoms are lameness, with more or less pointing of the foot when at rest, and heat towards the quarters of the lame foot.

Unlike laminitis, the lameness is inconsiderable at first, and increases as the disease progresses.

Being so deep-seated, it is very difficult to cure. In the incipient stages the most effectual remedy appears to be the insertion of frog-setons, requiring the assistance of a veterinary surgeon. In most instances the case is hopeless, and many a fine horse is sold to limp out a life of misery, drawing a hack cab, or, with a refinement of cruelty, is subject to the operation of unnerving the foot, which, by destroying sensation in that part, enables the animal to travel without apparent lameness, though the disease continues to progress till part of the foot has been known to drop off in work. Being a result of work to which all horses are liable, no mode of prevention can be recommended.

Lateral Cartilages.—Another ailment of the foot is more common than is generally supposed, called “Disease of the Lateral Cartilages.” It requires the skill of an anatomist to decide upon its presence. In fact, this and navicular disease are both very obscure in their origin and diagnostics, and a surgeon only can properly deal with them, as well as with all other diseases that are not very distinctly marked, and in their early stages not important.

Thrush.—A disease of the frog: the cleft becomes eaten away, and a foul matter is secreted. It more frequently attacks the hind than the fore feet.

By some it is said to be constitutional, but it is much more probably the result of neglect of the foot in the stable, the hind feet being oftener affected, from the fact of the urine and fÆces coming more immediately under their tread.

At every shoeing or removing, the frog should be perfectly cleared of all defective parts by the knife, and where the disease has once manifested itself the cleft should be kept continually stopped with tar and tow. A return to a healthy state is likely to be tedious, therefore continued attention to these directions is necessary. If a severe case, use a bar-shoe, to avoid the wear and tear of the road, and which will also help to keep the pledgets of tar and tow in their place. To prevent thrush, let the litter and bedding be completely removed from the horse every morning till bedtime at night; let the pavement be kept scrupulously clean through the day; attend and wash the feet, examine them frequently, and upon the slightest sign of the disease use the remedial means.

Quittor.—This is a disease of the feet, wherein, either from delicacy of or accident to the sole, the sensible part becomes affected. A suppurative sinus is formed, eating away till it often comes out at the coronet. Once it reaches this, the animal, unless of great value, might as well be destroyed, the restorative process being of a most tedious and expensive character, requiring continual manipulation by a surgeon.

By careful shoeing (where nails are not driven out of their proper direction) and a most exact examination of the foot where any extraneous matter, such as glass, gravel, &c., is suspected of having entered or damaged it, quittor will most probably be avoided.

Canker seldom attacks gentlemen’s horses, or well-bred ones. It is literally a change of a portion of the foot into a kind of fungus, sometimes commencing in the sole, sometimes in the frogs, and is aggravated by foul litter, bad stabling, and general bad care.

As no dressing or external application will restore the foot without manipulation, a surgeon only can deal with it.

Cracked and Greasy Heels.—Animals of languid circulation in the extremities are more susceptible of such diseases, which are induced and aggravated by lazy ignorant grooms pursuing their objectionable practice of wetting the legs, and leaving them to dry themselves.—See page 13.

Symptoms are tumefaction and soreness of the hinder part of the pasterns, even to fissures emitting matter.

Clip away the hair in the first instance, so as to be able to cleanse the sore by washing it with warm water and soft soap, drying it perfectly. Then apply glycerine lotion (page 158).

If the sore seems likely to incapacitate the animal from work, administer a mild aloetic purge (page 108). Very serious consequences may result from the indolence of grooms in neglecting this ailment. In acute cases, the sore, eating into the tendon, produces mortification and death. I have myself lost a valuable animal from this disease, through the gross neglect of my grooms in my absence.

Except in the very earliest stages, and in palpably trifling cases, a veterinary surgeon should be consulted, especially in what is called “grease,” or matter running from these cracks. The preventive means are, never to allow water to your horses’ legs above the coronet on any pretence whatever, and if by accident or work they get wet, to have them rubbed dry as promptly as possible.

Shelly Hoofs (or splitting open of the external part of the horny hoof).—The feet of some horses are more subject to this disease than those of others, from the fibrous structure being more dry with them.

This fibrous structure forming the hoof is found, on microscopic examination, to resemble a lot of hairs all glued together into a hardened mass, and where the adhesive matter is of a drier character than usual, the hoofs are more brittle. With some horses this results in “shelly hoofs;” they don’t split, but are perpetually breaking away. With this description of hoofs, tar is the best possible application. Neither grease nor oil should ever be used—these only aggravate the disease, as on close observation they will be found to act as powerful astringents, excluding the healthy action of air and moisture upon the part most in need of them. Strange to say, tar, from its pungent properties, induces healthy action in the part, and is peculiarly adapted to promote the growth of the fibrous structure as well as lubricating it.

Sand-Cracks seldom go diagonally, but are either horizontal or vertical. I shall endeavour to exemplify the simple principle of this disease with a simple principle of remedy, dealing with it like a split in a board on which I desired to put an effectual stopper. In such a case I should carefully gouge out a small hole at each end of the split, beyond which hole the fissure would be certain not to pass. With the hoof the same principle can be carried out by filing an indentation directly across each end of the crack, only taking care not to file deeper than the insensible part of the hoof; or the end will be answered by using a red-hot firing-iron instead of a file, taking the same precaution not to touch the sensible part. I should also weaken along the edges of the crack itself by rasping them down. Over the crack, if deep, should be strapped a thin pad of tow and tar, to induce reproduction and prevent foreign substances from entering the fissure.

Unless by the grossest neglect, no sand-crack will have been allowed to go beyond the reach of the foregoing treatment, but in some cases the effect of negligence and ignorance is seen in the horizontal crack running almost round the foot. In such cases it will generally be found that with a flat foot (inclined to greater malformation) the toes have been suffered to extend, shoeing after shoeing, by the smith allowing a great accumulation of wall over the toe, until the centre has become weakened into a fissure. Such a state of things seldom or never occurs in a gentleman’s stable, but is to be met with among farm-horses or those accustomed to heavy draught.

The careful strapping-up with tar and tow, which must be constantly attended to, rest, and the indentation process, will, with time and care, effect a cure.

Sand-crack, especially the vertical, is more dangerous and tedious the nearer it is to the coronet. This once divided, the case becomes serious, the coronet being very vascular, and a split here requires a great deal of care to induce it to take on union. Unless the closing commences at the coronet, and continues as the hoof grows down, it will never close at all; in fact, if the coronet be divided, it is fortunate if the crack does not go the whole way down to the shoe. If it does not, the lower end should be weakened by filing an indentation at its lower extremity, weakening the sides of the crack by rasping them, and keeping the hoof strapped round with dressings of tar and tow, also (a most important part of the treatment) paring away the wall of the foot (above the shoe and immediately under the crack) an inch—that is, half an inch on each side of it—making as large a vacuum as can with safety to the sensible parts of the foot be pared away, directly under the crack and over the shoe; the object of this being that all parts of the wall except that under the crack shall press on the shoe. It is obvious that by the above means every movement of the horse, in place of aggravation, will tend towards alleviation of the disease, by pressing the weakened sides of the fissure together. For the foregoing reasons, in the case of a vertical crack the shoes had better remain on, while in the worst cases of the horizontal crack, as its weight round the bottom tends to weaken the centre of the hoof where the crack is likely to be situated, it had better be removed (or light tips worn), its absence also enabling the wall of the hoof under the crack to be rasped as thin as possible. In vertical cracks the use of a bar-shoe will tend to keep the foot together (page 81).

Corns are occasioned by the inflexible shoe pressing on that part of the sole, or possibly from friction of the bones upon its internal surface. They present the appearance of a red effused bruise, almost invariably situated on the heel of the sole of the inside quarter of the fore feet.—See illustration, fig. 3, page 130.

When neglected, they occasion severe lameness, and go on to suppuration.

Broken knees are also frequently the result of neglected corns.

A horse that is habitually properly shod is never likely to have a corn. It arises entirely from want of attention and judgment in the smith. The groom, who should always stand by when a horse is shoeing, ought to be instructed to see that the farrier with his drawing-knife invariably pares out the sole at the seat of corn; it can be no injury whatever to the foot when properly done, and is the best preventive of corns. Also take proper care that the shoes are so put on that they cannot by possibility press upon the sole.

For prevention, keep the seat of corn well pared away, and dress with tar, unless in the suppurating state, when it requires poultices (page 160), and the ordinary treatment for that state, and full rest.

Over-reach or Tread proceeds from the shoe of one foot coming in contact with the soft or sensible part above the hoof of the other. As the parts likely to be affected round the coronet are full of vessels, the simplest remedial means are the safest—viz., water-dressing (page 160) in the first instance, and afterwards chloride of zinc lotion (one grain to the ounce of water), or glycerine.

Broken Knees.—Most travellers on the road know what style of thing this is, so it is needless to describe it.

In bad cases, where the bones are exposed, and there is any appearance of synovia or joint-oil, place the horse in the nearest convenient stable, and leave him there to be attended to by a professional man as soon as possible. When the abrasion is merely superficial, take the animal quietly to his stable, if near.

In any event, wash the wound with warm water, which, if it be at all deep, should be done by squeezing the water above the wound, and allowing it to run down, as this part of the leg is very delicate and sensitive, and rough handling with a cloth or sponge should be avoided.

Afterwards apply a lotion of chloride of zinc, one grain to the ounce of water.

Tie the creature’s head up in such a way as that he cannot possibly lie down, until the healing process has assumed sufficient health to render it safe to allow of the knee being used in lying down and getting up.

Give one or two mild purges, according to the time he is laid up and the healthiness of the wound. To promote the growth of hair, use, when the knee is perfectly healed, hog’s lard mixed with very finely powdered burnt leather to colour it; it is as good and safe a thing as can be employed for the purpose. Otherwise use weak mercurial ointment. For prevention, avoid the use of bearing-reins in harness; in shafts, keep the weight off your horse’s back; keep out of the way of ruts and stones upon the road, and be very careful of your beast when the work you are giving him is calculated to make him leg-weary.

In riding, teach your bearer to depend on himself, not on you: at the same time, don’t leave him to himself altogether. Go gently round sharp turns, and don’t ride fast down-hill on the road, though on the turf or in harness the pace may be accelerated with impunity. Avoid inflicting sudden, injudicious, and undeserved chastisement; restrain starts or alarms; have your horses properly prepared in frosty weather; also be sure that the seat of corn is kept well pared out in shoeing. If your saddle has shifted forward out of its place, dismount and regirth it where it fits, so that when you remount your weight will be properly placed away from the shoulders.

When the road is the only place available to have your horses exercised, see that your grooms put on the knee-caps.

Splints are a well-known affection of the fore leg, presenting the appearance of a bony protrusion along the canon or shank, which, though unsightly, is not very important, unless when lameness ensues.

As it is not my intention to enter into professional technicalities in this work, I shall merely remark that, by letting the horse continue in moderate work, though lame, with the application of Stevens’s ointment, according to the directions accompanying it, absorption of the bony matter will be obtained, or, at all events, it will become so far resolved that the surrounding structures being able to accommodate themselves to what remains of it, their action will not be interfered with, and lameness will consequently no longer appear. Veterinarians sometimes perform a simple operation for splints which is said to be efficacious—namely, that of dividing the periosteum with a bistuary, the periosteum being that membrane which encases all bones like a skin. When this is cleverly done, there is little or no disfiguration left. Setons also are sometimes run over the exostosis or bony excrescence, but I deal only with simple remedies. As splints cannot be prevented, being a common result of work in young horses, the next best thing to be done is to resolve them while in an incipient state.

Clap of the Back Sinew—i.e., inflammation of the sheath under which the flexor tendon passes (as the most able practitioners deny that the tendon itself can be stretched, though it is liable to rupture about its insertions)—is best treated, according to some, by cold refrigerant lotions, Goulard lotion, solution of acetate of lead, &c.

I prefer plain water-dressing (page 160) placed loosely round the affected part of the leg, and the use of a high-heeled shoe (page 82). When the attack is beyond the reach of such mild treatment, the veterinary surgeon will probably advise blistering and firing to act as a perpetual bandage.

Moderate work on even surfaces will be the best preventive of this disease, and having the pavement of your stables made nearly level, as described under the head of “Stabling” (page 8).

Wind-Galls are undue distensions of the bursÆ or bags of synovia at the back and sides of the lower part of the canon or shin intended to lubricate the adjacent structure. Though unsightly, and no improvement to the action of the horse, they can be reduced by external absorbents (page 159), also by bandages with refrigerant repellants, such as vinegar and water (see “Grooming,” page 12).

Riding-Bone is an unhealthy enlargement round the pastern above the coronet, generally in front, and may be removed in the incipient stage by external absorbents (page 159), beyond which a professional man had better be consulted.

Wrench or Wrick, occasioned by accident or strain in work over a rough path by a slip, presents generally no external swelling or indication of suffering beyond lameness in movement; but on close examination, inflammation will be discovered by extra heat about the part affected. Remove the shoe, give plenty of rest, and apply water-dressing (page 160) round the affected part. A purge may be administered, as recommended in all cases where the animal is laid up for several days. To avoid wrench, care should be observed in starting, turning, and working a horse, especially on uneven ground or when heavily laden.

Mallenders and Sallenders denote a scurvy state of the skin inside the bend of the knees and hocks. Let the parts be cleansed with hot water and soft soap, and rub in equal parts of hog’s lard and mercurial ointment mixed; if there be a positive crack or sore, use the chloride of zinc lotion (see page 158) till healed. Keep a good attentive groom, and see that he does his work, as such blemishes are occasioned by carelessness and want of cleanliness.

Spavin is like splint, a bony excrescence, but on the lower part of the leg, at the inside of the hock towards the front, occasioned by local derangement from overwork of the structure.

If it does not produce lameness it had better be left alone; but otherwise, the horse being placed in a loose-box, rest should be given, and treatment with absorbents (page 159), the use of Stevens’s ointment, &c., persisted in. A mild purge or two during the process will be beneficial.

As in nearly all affections of the legs and feet, proper reasonable work and due care will avert the disease or disfigurement.

Curb is an enlargement of the tendon or its sheath at the lower part of the back of the hock, with a good deal of local inflammation attending it.

It is greatly occasioned by the fashion some riders have of habitually throwing their horses back on their hocks by severe use of the bit.

Use water-dressing to reduce inflammation, then absorbents, such as Stevens’s ointment (page 159). Give rest, &c., as directed for Spavin.

String-Halt is a well-known and only too conspicuous defect or affection of the nerves of the hind limbs, or emanating from the spine.

As its local origin is obscure, so also is the method of dealing with it.

It is in no way dangerous, though unsightly, and seriously deteriorating to the value of the animal, although it is said not to interfere much with his working powers.

Capped Hock is a pursy swelling over the os calcis or heel-bone at the end of the hock, generally produced by kicking either in the stable or against some object in harness, or possibly in consequence of exertion in getting up and lying down on a scanty bed, especially where the paving-stones are uneven.

Use hot fomentations, loose water-dressing, followed by rubbing in iodine ointment, if necessary, for reduction, but this must be done with judgment and careful observance of the effect the iodine produces. Or, after using hot fomentations for a week, apply gas water (which can be obtained from any gas-works) with a sponge dabbed on every hour during the day. This treatment, if persisted in, is said to be very efficacious.

For prevention, keep a good bed for your horse to lie on at night. See “Kicking in the Stable” (page 85) and “Kicking-Strap” (page 58).

Thorough-Pin and Bog-Spavin are, like wind-galls, an undue distension of the bursÆ containing the synovia intended to keep the surrounding parts of the leg lubricated; such distension interfering with the circulation of the vein in front of the hock is denominated “Blood” (or Bog) Spavin; at the back and sides of the hock these distensions are called Thorough-Pin.

The treatment is with hot fomentations and gas water, as in “capped hock,” or other absorbents, especially Stevens’s ointment, iodine ointment, blisters, and actual cautery, which remedies had better be tried in rotation, the three latter only by a practitioner; but unless the distensions produce lameness, it is perhaps preferable not to meddle with them at all.

There are other diseases of the feet and legs, but requiring very delicate definitions: they must be left altogether to the professional man.

As a rule, in all cases where it may be considered desirable to use stimulating or strong absorbing treatment externally to cure lameness, the inflammation should be first fully abated by local cooling applications; and in severe cases, purges administered before the application of blisters or powerful absorbents.

FARCY.

This dreaded disease is, I believe, like glanders, incurable, and generally ends in glanders itself.

Some practitioners seem to be under the impression that it only attacks worn-out and ill-conditioned animals; but from personal losses and sad experience I may venture to differ entirely from such an opinion, and to state that I have seen horses in the finest condition lost by it. No doubt feeble animals are very liable to it, but the disease is not confined to such constitutions. I have remarked that, when contracted by high-conditioned horses, it can be traced to their being called on occasionally to do extra work, followed by entire rest for days together, as a sort of equivalent for the spurt of work done, during which period of rest (considered necessary on account of the beast’s supposed state of exhaustion) his powers are taxed with the same amount of high feeding as if he were in full work.

Thus the absorbent system seems to become diseased, and farcy-buds appear, accompanied by craving thirst, in which case, or on the least suspicion of the disease, reference should at once be made to a professional man.

From these buds (whence after a time matter is seen to exude) small cords may be traced leading to other swellings, rather serving to distinguish the early stages of farcy from surfeit, besides that in surfeit the lumps appear indolent and scabby.

To guard against this scourge of the stable, as the disease is contagious, be careful what company your horses keep, and let reason be used in the working, feeding, exercising, and general care of your stud.

What is called Water Farcy is neither dangerous nor contagious, and arises from debility of the system, occasioned probably by overwork and indifferent feeding.

It is generally marked by a dropsical swelling of the legs, mostly the hind ones. It is not common in gentlemen’s stables, where horses are less worked and better cared for than their neighbours.

The best cure is friction to the swelling, moderate work, and improved feeding; and give a ball twice a-day, each dose with

Sulphate of iron,	2 drachms.
Powdered ginger,	2 ”
Powdered gentian,	2 ”

To be mixed with palm-oil or lard.

RINGWORM.

Ringworm is characterised by one or more scurfy or scaly circular patches on the skin where the hair has fallen off. As soon as discovered, let the parts be washed with soap and tepid water twice a-day; and when they have been gently but perfectly dried, apply rather thickly the following ointment over the spots:—

Animal glycerine,	1 ounce.
Spermaceti,	1 ”
Iodide of lead,	2 drachms.

Rub the glycerine and spermaceti together, and when thoroughly incorporated, add the iodide of lead; give also every night the following drink:—

Liquor arsenicalis,	1 ounce.
Tincture of muriate of iron,	1½ ”
Water,	1 quart.

Mix.—Dose, half a pint.

Continue this drink until the disease has disappeared.

Should ulceration remain about the circumferent edges after the central bare spot has been apparently cured, apply to the affected circuit six times a-day persistently the following lotion:—

Chloride of zinc,	2 scruples.
Water,	1 pint.

The animal should be thrown up from work during this treatment, which may be requisite for a month, and good food given.

Administer also a powerful alterative or two during the course of treatment, more particularly if the case is obstinate.[32]

Other practitioners recommend, with the administration of alteratives, the simple application of a solution of nitrate of silver, 30 grains to 1 ounce of water (distilled), applied every second day to the eruptions, until they are destroyed.

SURFEIT

is an eruption on the skin, and generally gives way, if attended to immediately on its appearance, by relaxing the bowels mildly, giving partly green food instead of hay and bran mashes; at the same time keep up the strength by feeding with the best oats and a little beans, alternately with the laxative treatment.

Should these means not suffice, or the disease become worse, consult a medical practitioner, who will probably administer diuretics; or if you cannot procure a professional man, give the following excellent tonic and alterative drink, recommended by Mr Mayhew:—

Liquor arsenicalis,	1 ounce.
Tincture of muriate of iron,	1½ ”
Water,	1 quart.

Mix, and give daily half a pint for a dose.

Hidebound requires the same treatment as surfeit.

Mange is generally the result of insufficient food and other privations endured at grass, and of the neglect of the skin consequent on animals being turned out for a time to take care of themselves.

It is highly contagious, and is now admitted to be occasioned by an insect which is engendered in the foul coat.

A capital wash is recommended by Mr Mayhew, viz.:—

Animal glycerine,	four parts.
Creosote,	half a part.
Oil of turpentine,	one part.
Oil of juniper,	half a part.

About a pint and a half is said to be the quantity required to make one dressing. Every portion of the entire coat should be saturated with this wash, and thus left for two clear days, when it should be washed clean with soft soap and warm water, equal care being taken to omit no part of the body, which should afterwards be thoroughly dried and the coat well dressed or whisked.

When all is dry and clean apply a second dressing, proceeding as directed for the first, and a third after the two days have elapsed and the second cleaning process has been thoroughly gone through, after which the disease ought to be eradicated. A mere disposition to scratching is generally successfully treated by giving bran mashes night and morning for some days, and part green food instead of hay. Others recommend for mange, as most successful, the following application, to be well rubbed in once a-week all over the animal with a stiff horse-brush:—

Barbadoes tar,	1 part.
Linseed oil,	3 parts.

To be mixed and gently warmed in a pan.

The whole of the horse’s body to be thoroughly washed with soft soap and warm water, and perfectly dried, previous to rubbing in the foregoing application.

SORE BACK, WITHERS, AND SITFASTS,

should be carefully attended to with poultices or water-dressing (see page 160), while a disposition to throw off pus is present, after which the application of healing agents (among which chloride of zinc lotion and glycerine are now prominent) is the proper course, but applicable only to decidedly trifling and superficial cases. It is imperative, if a cure be desired, that no pressure whatever from the saddle or any other cause of irritation be permitted; therefore, unless a saddler can effectually chamber and pack the saddle so as to prevent the possibility of its touching on or near the sore, the saddle must not be used at all.

The worst and common result of sores on the back is, that sinuses or cavities, with an almost imperceptible orifice, insidiously eat away like poll-evil into the more important part of the adjacent structure. Here the aid of the veterinary surgeon is indispensable.

For prevention of sore back avoid injurious pressure from an ill-fitting saddle; also removing it too quickly from, the back of a heated animal (see “Work,” page 37). Pressure of the terret-pad (see page 59), or of the roller from not being properly chambered over the ridge of the back (see page 19), must also be carefully guarded against.

WOUNDS,

if deep or dangerous, should meet with the immediate attention of a surgeon, as none but anatomists should deal with them. Generally speaking, the loss of a moderate quantity of blood is rather beneficial than otherwise, tending to avert inflammation. Where water-dressing (see page 160) can be applied, nothing is better in the first instance; and when the wound is fairly cleansed and evidently healing, the chloride of zinc lotion (see page 158) will advance that process and help to dry it up. When the surface is perfectly healed and a new skin formed, the growth of the hair will be promoted by the application of hog’s lard coloured with very finely powdered burnt leather.

MEGRIMS OR EPILEPSY

may proceed from the effects of the sun in very hot weather, from congestion of the blood-vessels of the brain and head, or from disordered stomach or indigestion. The horse when at work suddenly evinces a disinclination to proceed, appears bothered, and shows unaccountable perverseness—sometimes staggers and falls. Release him at once from whatever work he may be at; if the cause can be descried, treat in the most reasonable way accordingly. If the illness is supposed to proceed from the heat of the sun or congestion of the head, dash water on the head and keep it enveloped in cold wet cloths; also cool the system by aperients, giving rest for some time. If from indigestion, repeated mild aperients should be administered.

It is a strange fact known to those who are experienced on the road, that these fits are seldom or never taken during work at night. When such attacks are habitual the animal is only fit for farm-work.

CRIB-BITING AND WIND-SUCKING.

Some able veterinarians declare these habits to be the result of an endeavour to eject acidity from the stomach as the horse cannot vomit, while others compare it to the human belch. It is almost impossible to cure a crib-biter; the only thing that can be done is, to palliate and prevent it, which is essential, as the habit is not only injurious to the horse himself, but one that, strange to say, is most readily imitated by his companions; in whatever stable such an animal may be, the others are liable to become crib-biters.

By leaving a lump of rock-salt in horses’ mangers many ailments may be averted. Licking it is a resource to them in their hours of solitary confinement. In the present instance a lump of chalk might be added, for the animal to amuse himself at any moment that he is left without a muzzle (which should be made for him by an experienced saddler, and constantly used). The chalk being essentially antacid, is decidedly useful if the habit is supposed to result from acidity.

As the muzzle should not be left off for any length of time, the food should be prepared to be taken up in the most rapid form—viz., a small quantity of chaff to bruised oats. When the beast finds by experience that his feeding-time is limited, with starvation for the alternative, he will probably prefer his food to gnawing the iron during the short space allowed him without his muzzle. A simple remedy sometimes used with good effect is, keeping a tightened strap round the creature’s neck when he is not feeding; and I have known the covering of every portion of the stall within his reach with rabbit or sheep skins, the hair outside, to effectually check a crib-biter for the time being,—the habit being resumed, however, on his removal to another stall.[33]

METASTASIS.

As this term is frequently used by practitioners, it may be well to explain that it is a Greek word signifying a removal from one place to another, employed as a technical designation in describing a change of the seat of disease from one part of the animal structure to another, which is by no means uncommon: for instance, when the feet are attacked with fever, that malady will appear to remove itself to some other and probably distant part, and fix itself on the lungs or other viscera, the same way that inflammation of the lungs and other parts of the upper structure will change amongst themselves, or from their own seat of disease to the feet.[34] I have even known superpurgation (occasioned, in a pair of horses, by undue, but not severe work when under the irritation of the medicine) to cause fever of the feet, by a metastasis, changing the seat of irritation from the internals to the extremities—a very palpable case in point.

SETONS.

The insertion of a seton properly belongs to the professional man, and only for the guidance of persons who, from living in remote neighbourhoods or other causes, cannot possibly procure the assistance of such, the following information is inserted, in order to obviate the necessity for some ignorant farrier being permitted to perform the operation after his own fashion. The skin is first divided, by surgical scissors made for such purposes, to the width of the seton-needle to be used, which must be wide or narrow, according to the orifice required, with white linen tape passed through its eye, about the same width as the needle and orifice. The needle is then inserted at the opening, and, passing superficially under the skin, is directed towards the point where the lower or depending orifice is intended to be, and where the needle and tape are drawn out. Sufficient tape must be left at each extremity to admit not only of its being tied round small rolls of tow which keep the tape from running through at either side, but some inches of the tape should be left in addition at one end, to allow of a portion being drawn out at one orifice each day, and a fresh piece with dressing being drawn in at the other.

In cases where there is already an upper orifice with sinuses, the surgeon (if he does not lay the place entirely open with a knife, which, if the sinuses are deep-seated, he will do) will insert the seton-needle at such orifice, no incision with the scissors being necessary, the direction of the sinuses having been first ascertained by the careful use of the probe. The dressing to be applied to the tape will be either chloride of zinc lotion, Venice turpentine, or tincture of arnica lotion (see “Lotions”), according as the healing or discharging process may be desired, the first being the healing application. Farriers attempting this operation will even now adopt an old and most objectionable practice of tying the two ends of the seton-tape together, and turning it round at each fresh dressing; the consequence being that, if anything happen to catch in the loop thus made, the whole piece of skin may be dragged out.

LOTIONS, PURGES, BLISTERS, &c.

AS A RULE, ALL VOLATILE OILS OR TINCTURES SHOULD BE ADMINISTERED IN COLD WATER, OR LIQUID.

Strong Heeding Lotion.—Chloride of zinc, two scruples; water, one pint.

Weaker, as for Sore Mouth, &c.—Chloride of zinc, one scruple; water, one pint.

To encourage Pus, and heal subsequently.—Tincture of arnica, one ounce; water, one pint.

To keep off Flies from Wounds or Bruises.—Apply a rag dipped in solution of tar.

Glycerine Lotion.—Glycerine, half pint; chloride of zinc, half ounce; water, six quarts.

To abate External Inflammation.—Vinegar, two ounces; Goulard lotion, one ounce; water, two pints.

Liniment for the Neck in Cold and Distemper, Sore Throat, &c.—One part spirit of turpentine, two parts oil, mixed, or equal parts of each, and rubbed in once or twice daily.

Purges.—A mild purge is composed of—aloes, four drachms; extract of gentian, two drachms.

A very mild Laxative Drench.—Castor-oil, three ounces; linseed-oil, two ounces; warm gruel, one pint—Mix.

Of linseed-oil alone the ordinary dose is one pint. If ineffectual, to be repeated, with the addition of twenty drops of croton-oil.

Alterative Ball (for surfeit and skin diseases).—Cream of tartar, half drachm; nitre, two drachms; flowers of sulphur, half ounce—Mix in mass.

External Absorbents.—Iodine ointment and tincture, Stevens’s ointment,[35] water-dressing.

Restoratives or Renovators—Drenches.—A quart of stout, morning or evening; hay-tea, when mashes are refused; gruel properly prepared (page 161) and linseed mashes (page 22).

Soothing Drench in Colic.—Sulphuric ether, one ounce; laudanum, one ounce; linseed-oil, one pint.

Astringent Drenches (for diabetes).—Diluted phosphoric acid, one ounce; chilled water, one pint.

Or—Oak-bark, one ounce; alum, quarter ounce; camomile tea, one pint—Made into a drench.

Feeding on old hay is generally effectual to check purging.

Clysters[36] (for diarrhoea, dysentery, or over-purgation).—Laudanum, one ounce—Mixed in three pints warm thin starch, repeated every half-hour, as long as necessary. (The above is soothing and astringent.)

(For inflammation of the bladder or kidneys.)—Injections of warm linseed-tea constantly repeated.

(For dysentery.)—Injections of cold linseed-tea.

(For colic.)—Injection of one pint of turpentine mixed in two quarts of hot soap-suds. (Soothing and laxative.)

Ointment (to recover hair).—Equal parts hogs’ lard and mercurial ointment, with very finely powdered burnt leather to colour it.

Poultices are made of bran or linseed-meal, with boiling water, and applied as hot as bearable. They are seldom used except for the feet, in which cases the leather shoe is useful.

Water-dressing (for sores, &c.)—Pads of linen kept continually fully saturated with water, and entirely over them is kept fixed a waterproof covering of oiled silk or calico (gutta-percha is too liable to tear), to prevent evaporation. The pads should be changed every three or four hours, and cleansed where they are intended to promote effusion of matter.

For Acidity.—A lump of chalk kept in the manger.

For General Health.—A lump of rock-salt always in the manger.

For Worms.—One to two grains of arsenic and twenty grains of kamela twice daily (each dose mixed in a handful of wet bran, and given with oats or other feeding) for eighteen days, and a purge the nineteenth morning. The horse may get moderate work during the administration of the powders. Or, common salt, a tablespoonful daily, to be mixed with the food.

Strong Mustard Blister.—For cases of acute inflammation, mustard to be made into a paste, eight ounces; oil of turpentine, two ounces—To be well rubbed into the chest or belly in severe inflammation.

Blisters should never be applied to a horse’s four legs at the same time, as is the practice with some farriers. Two legs only should be blistered at once, and an interval of three or four days suffered to elapse before the application of the remaining blisters. The animal’s head should be tied up for at least thirty hours after the blister is put on, to prevent his gnawing the part; but if a cradle round the neck can effect the same purpose in cases where other parts are blistered, its use is preferable to tying up the head.

Sedative.—To allay excitement after a wound, &c.: tincture of aconite, ten to twenty drops, in drench of one pint of water with chill off.

To make Gruel.—Mix well a pound of oatmeal in a quart of cold water; put this mixture in a stew-pan containing three quarts of boiling water, stir all well over the fire till it becomes thick, then leave it aside to cool sufficiently to be eatable.

Disinfectant.—As it will perhaps be useful to any proprietor of horse-flesh, who may unfortunately have had contagious disease in his stables, such as farcy or glanders, to know how premises should be disinfected according to the most approved means, the following recommendations of Government for purifying the holds of ships, during the prevalence of rinderpest, are appended:—

Suggestions for Disinfecting Holds of Ships.—The Government has issued the following circular to the shipowners and veterinary inspectors of Irish ports. It must not be forgotten that the importation of raw hides is still permitted.

“23d August 1865.

“The usual means had recourse to for the purpose of disinfecting the holds of vessels (such as washing and subsequently applying diluted disinfecting solutions, the most generally used of which is chloride of lime), do not possess sufficient efficacy, particularly within the limited time that can be devoted to that purpose, without interfering with the commercial interests of the vessels.

“It would occupy too much time to carefully scour and afterwards apply a disinfecting fluid to the entire surface of a ship’s hold, in which, generally, there are many crevices and parts that cannot be reached by the hand or brush. Such crevices and parts are capable of retaining the contagious and infectious principles in all their virulence.

“Holds of vessels, and all other chambers from which the external air can be excluded for a time, can be, comparatively speaking, most effectually disinfected by filling them with chlorine gas, the great disinfecting principle of chloride of lime. The gas insinuates itself into every chink, crevice, and part of the chamber in which it is confined, and more effectually decomposes the contagious and infectious compounds, whether they be solid, fluid, or aeriform, than any other disinfectant equally easy of application, and as cheap. The mode of disinfecting the hold of a vessel with chlorine is, to place a quantity of common salt and black oxide of manganese in a strong basin, which may be put into a bucket, to the handle of which a rope has been attached. Pour on the salt and black oxide of manganese their combined weight of sulphuric acid; then let the bucket containing the basin a little way down into the hold by the rope attached to its handle. The chlorine gas, being heavier than the atmospheric air, will quickly displace the latter and fill the hold. In a short time, when the hold has become filled with chlorine, the hatches may be battened down for about half an hour.

“Previous to using the hold again for live freight, a current of air should be admitted through it to remove the chlorine.

“Many recommend the use of charcoal; but it is not alone more difficult of application, but it is much less of a disinfectant than a deodoriser. Charcoal will not, like the chlorides, decompose the matter of disease. If the damp matter of glanders, or sheep-pox, be well mixed with a strong solution of chloride of lime, it will seldom produce bad effects by inoculation; but if pure charcoal of any kind be used, the contagious principle of the diseased matter is not at all diminished in its virulence—quite the contrary; similar results are found if cow-pox be the matter used in the experiment.

“The cost of the readiest materials for the production of chlorine gas is very trifling. The salt is not ¼d. per pound; black oxide of manganese but 4d. per pound; and sulphuric acid 1½d. per pound. These are the retail prices. A couple of pounds weight of each would suffice for a large-sized hold.

“The attention of the customs, shipowners, and veterinary inspectors is directed to the above disinfecting means.

Her Majesty’s Veterinary Surgeon,
