For this purpose, two men are required, one to remove and the other to apply. Four old cloths will be necessary. These, when removed, should be flung over a line, so that as large a space as possible may be exposed to the cooling action of the atmosphere. There is nothing so disagreeable in performing this office as might at first appear. The active agent of the lotion is a powerful disinfectant and deodorizer. The first cloth removes almost all the fetor, and hanging the wrappers subsequently over the line effectually purifies the atmosphere. The part being reduced to a comparatively natural temperature, the after-treatment consists in renewing the cloths so often as the heat returns; and in otherwise moistening the limb with some of the subjoined lotion thrice daily:-- _Lotion for the earliest stage of Grease._ Animal glycerin Half a pint. Chloride of zinc Half an ounce. Water Six quarts. To be employed after the manner already directed. When the cracks, with ulceration, appear, the previous lotion is too weak to be of much service; but the same treatment must be adopted: only one of the lotions subsequently given should then be used:-- _Lotion for the ulcerative stage of Grease._ Permanganate of potash or phosphoric acid One pint. Water Six quarts. Or-- Chloride of zinc One ounce. Creosote Four ounces. Strong solution of oak bark One gallon. Both to be used after the manner of the previous solution. Should the spurious granulations have begun to sprout, lose no time in having the horse cast. Have near at hand a small pot, with a charcoal fire beneath it. Let the vessel be full of boiling water. Within the fluid, previous to the casting, insert several irons; then throw the animal. With a keen knife excise the external bunches of proud flesh. As each lump is removed, much bleeding will ensue; therefore, before using the knife again, take an iron and lay it flat upon the raw surface. Should one not check the hemorrhage, return the first to the saucepan and apply a second. It is necessary to operate with as small a loss of blood as possible; for horses having grease are always old and debilitated. In this manner proceed till all the external growths are cut away. Then let the animal rise. Enough has been suffered for one occasion; more agony the exhausted system of the animal might not sustain. Besides, with every attention concerning the irons, the bleeding, generally, will not permit more to be accomplished.
