=RINGWORM.=--This is common in the domestic animals, especially in calves and young cattle, and is contagious. It depends upon the presence of a vegetable parasite, which develops and grows rapidly when it finds a suitable place for development. Ringworm may affect any part of the body, but its favorite seat is around the eyes, the face, ears, and neck of cattle, and sometimes the back and hindquarters. A gray crust appears on the skin, and the hair drops out. This keeps spreading in the form of a ring until around the eyes, the side of the face, ears, or neck may be covered with it. It appears in the same way on the back, hips, and inside of the hind legs. It does not seem to affect the health of the animal, as it is found in the well-kept as well as those poorly kept. First remove the crusts by washing with warm water in which one ounce of carbonate of potassium has been put to every quart of water. A brush should be used in washing the parts. Then use the following: Iodine 2 teaspoonfuls and vaseline 4 tablespoonfuls. Rub a little of this on with a gloved hand. Repeat in three days. Or mix carbolic acid 1 ounce with 2 ounces of alcohol and apply a little of this to the parts with a feather once or twice; this last is very effective. =ROARING.=--A disease, due to the wasting of the larynx; is characterized by loud, unnatural sounds after any violent exertion. The disease sometimes follows distemper and influenza or a local injury to the throat. Once established the disease is incurable. In its early stages repeated light blisters may help. A common blister can be made of a half teaspoonful of cantharides, a half teaspoonful of biniodide of mercury and 4 tablespoonfuls of vaseline or lard. =ROUP.=--A disease of the mucous membrane in fowls. It is of the nature of an inflammation, with a discharge from the eyes and nostrils usually accompanying. Damp and unsanitary quarters favor the development and spread of roup. It is clearly a germ disease, and, therefore, contagious. It is spread by means of infected quarters and fowls. All discharges must be destroyed by disinfection, and the diseased fowls quarantined off by themselves. The dead should be burned. Keep the quarters light and airy; admit an abundance of sunshine and fresh air. Feed wholesome, nutritious food, that the poultry stock may ward off the disease. The best treatment is that which prevents spreading to healthy fowls. If an outbreak occurs, disinfect thoroughly, liberally, and continuously. Antiseptics administered about the head will usually break up the disease. Creolin is good--say, 1 part to 100 parts of water. Kerosene is also recommended. In a sense, roup is the result of neglected colds. The birds sneeze, and manifest their uneasiness as animals do with common colds. A teaspoonful of pure carbolic acid to each gallon of drinking water is an excellent preventive and can be provided at small cost.
