It may be caused from improper feeding, or may be only a symptom of some other disease, particularly diseases of the heart, lungs, liver and kidneys. Dropsy is a morbid accumulation of watery fluid confined to certain parts of the body. The disease is divided into varieties corresponding to the respective localization of the accumulated water, as for instance, anasarca (water in the skin); ascites (water in the abdomen); hydrothorax (water in the chest). SYMPTOMS.—In the first form (anasarca) it is first noticed on the lower parts of the body, as the legs, under surface of the chest, etc. The skin is swollen and doughy to the touch and retains the impression of the fingers; but is neither painful nor of abnormally high temperature. In ascites there is a gradual enlargement of the abdomen and when pressed upon, the fluid can be felt to flow from side to side and the part with the water gives a dull sound on being struck. Breathing is quicker and impeded and the appetite diminished, but there is no fever. In hydrothorax the symptoms are much the same except that it takes place in the region of the chest instead of the abdomen. TREATMENT.—It will generally be relieved by giving the H.H., in doses of fifteen drops three times per day for trifling cases, or ten drops every three hours for the more severe ones. After a free discharge of urine is established, giving the medicine three times per day will be sufficient. Eczema (See also Mange page 23) In the horse, eczema represents practically all forms of skin disease except the parasitic and is seen in the following forms and regions. 1—A form seen in hot weather and variously known as herpes, lichen, summer or saddle mange, and heat pimples. This occurs under the harness where sweating is most profuse, at first as scabby pimples, after which the hair sticks together and falls, leaving scaly bare patches. 2—Then there is a form of scaly eczema which attacks the head, neck, shoulders, elbows, etc. This is a chronic form, with the production of branny scales with thickening of the skin accompanied by itching. 3—A pustular form which attacks chiefly the skin under the mane and tail. The skin is raw and weeping, while the hair mats together in masses and falls and there is a tendency to the chronic scaly form. 4—Eczema attacking the legs is known as mallenders and sallenders if on the back of the knee, or the front of the hock, while if above the heels, in the bend of the pastern it is known as grease. This is characterized by heat, swelling and redness, followed by a vesiculated weeping surface with the formation of a greasy, offensive discharge, scabs and cracks in the skin, followed by loss of hair. Sometimes the irritant secretion gives rise to production of fungus wart-like granulations, known as “grapes” accompanied by great thickening of the skin and swelling of the limbs.
