In the early, dry, scurfy stage of grease, the heels may be well cleaned with soft soap and water, and afterwards thoroughly dried, and then treated with a dilution of Goulard's extract--one part to eight parts of water, or one part with six parts of lard oil. In the mildest form of the stage of cracks and ichorous discharge, after cleansing, some drying powder, such as equal quantities of white lead and putty (impure protoxide of zinc), may be applied, or simply the mixture of Goulard's extract with lard oil may be continued. In the virulent form of cracks, accompanied with ulceration, the heels ought to be daily washed clean with warm water, and afterwards bathed with a mild astringent lotion, and every morning and evening thinly poulticed or coated with carbolized ointment; and the whole system ought to be acted on by alteratives, by nightly bran mash, and, if the animal be in full condition, with a dose of purgative medicine. In the worst and most extensively spread cases, poultices of a very cooling kind, particularly poultices of scraped carrots or scraped turnips, ought to be used day and night, both for the sake of their own action, and as preparatives to the action of the astringent application; and the whole course of treatment ought to aim at the abatement of the inflammatory action, previous to the stopping of the discharge. Nothing tends so much to prevent grease and swelling of the legs as frequent hand rubbing and cleansing the heels carefully as soon as a horse comes in from exercise or work. In inveterate cases of grease, where the disease appears to have become habitual, in some degree, a run at grass, when in season, is the only remedy. If a dry paddock is available, where a horse can be sheltered in bad weather, it will be found extremely convenient; as in such circumstances, he may perform his usual labor, and at the same time be kept free from the complaint. Foul in the Foot. This name is given to a disease in cattle, which presents a resemblance to foot rot in sheep, but is different from this. It appears to be always occasioned by the neglect and aggravation of wounds and ulcers originating in mechanical injury--particularly in the insinuating of pieces of stone, splinters of wood, etc., between the claws of the hoof, or in the wearing, splitting, or bruising of the horn, and consequent abrasion of the sensible foot; by walking for an undue length of time, or a long distance upon gravelly or flinty roads, or other hard and eroding surfaces. It is sometimes ascribed, indeed, to a wet state of the pasture; but moisture merely predisposes to it, by softening the hoof and diminishing its power of resisting mechanical injury.
