Such is the history of ulcerated joint. All joints are exposed to ulceration; every bone in the fore and hind leg may be thus affected. The small bones of the hock are those most commonly diseased; whenever this is the case, the only termination which can reasonably be hoped for is that the inflamed surfaces may be united. The bones are then bound together by osseous union, and are, of course, firmly locked; they are no longer capable of the slightest movement one upon the other; but this is no vast evil: many animals are now at work having the smaller bones firmly united by osseous deposit. Horses in that condition are far from useless, even for the highest purposes. The man whose animal gets ulceration of the hock-joint ought to allow the injured quadruped even twelve months of uninterrupted rest. The first thing is to get the sufferer into slings; the earlier this is done the better; it takes off the weight from the affected joint, relieves the pain, and gives the system full opportunity to rectify the lesion. To draw blood to the part and so promote deposit, rub in, once every two days, some of the embrocation recommended in the article on "Rheumatism," which is thus composed: of soap liniment, sixteen ounces; liquor ammonia, tincture of cantharides, and of laudanum, of each two ounces. There need be no fear of applying friction; the utmost pressure made upon an ulcerated joint can call forth no response. When the joint is embrocated, wrap the part loosely in flannel, using an elastic webbing to fasten the portion above and below the hock, and not tying any fastening around the painfully-diseased member; give three feeds of corn, a few old beans, and sweet hay for each day's support, while the treatment lasts. The improvement will be denoted by the animal bearing upon the affected limb; after three mouths or longer, the slings may be removed; in another three months, the horse, should the pace be sound, may perform gentle work. However, the first three months must be reckoned from the date when the animal commenced to bear continuously on the ulcerated joint; in short, the slings are not to be removed until long after the quadruped has, by its carriage, declared them to be useless. Then, for the three subsequent months, the work must not be violent; time should be allowed for the union to be confirmed, for, among the many diseases the horse is exposed to, there is not one more treacherous or more liable to relapse than occult spavin.
