A mild attack of dropsy is indicated when the legs of a horse swell up, due to lack of exercise and poor circulation as occasioned by standing in the stable. The first thing, of course, is to start better blood circulation. Hand rubbing is good; bathing with hot water acts similarly. Any medicine that stimulates the action of the kidneys will prove helpful. Saltpeter is excellent for this. Use once a day for three or four days in succession, and give 4 tablespoonfuls at a dose. In connection with this treatment supply the animal with succulent or laxative food, that the bowels may be kept free and open. Any of the tonic condition powders will help. =DYSTOKIA.=--See Obstetrics. =ECZEMA.=--An inflammatory, non-contagious disease of the skin in which eruptions may occur in the form of vesicles, pustules, crusts, scales, or simple redness. Its principal victims are animals fed rich food, the penalty being associated with some gastric or intestinal disturbance. Treatment is both external and internal. The former should be in the nature of washes for cleanliness and healing. Tar soap is recommended. A wash made of 4 tablespoonfuls of carbonate of potassium dissolved in a quart of water is also excellent. After a good rub with this, wash off with warm water. If itching causes any distress, prepare a wash consisting of 2 tablespoonfuls of acetate of lead, 8 tablespoonfuls of tincture of opium and a quart of water. Where scales have formed and the skin is thick and scurvy, rub in a little with the fingers some biniodide of mercury and vaseline. Use 2 teaspoonfuls of the mercury and 8 tablespoonfuls of the vaseline. One application will do the work. If the case is bad, several parts being affected, treat only one part at a time with the mercury salve. Be certain to have the animal tied so that he cannot get his mouth to the treated region. For internal treatment let the physic come first. For horses, mix 4 tablespoonfuls of aloes, 4 tablespoonfuls of ginger and 4 tablespoonfuls of soda carbonate dissolved in a pint of boiling water. Let cool to proper temperature and give as a drench. For cattle, give a pound of Epsom salts and 4 tablespoonfuls of ginger in water as a drench. Following the physic should come a good blood tonic. To prepare this, mix 16 tablespoonfuls each of nitrate of potassium and sulphate of iron. Give in doses of 1½ tablespoonfuls daily in a bran mash until all is used.
