=PERITONITIS.=--An inflammation of the membrane which lines the abdominal cavity and which also invests the abdominal organs. It may be caused from some exposure to cold after some weakening disease. Some injury to the abdomen or belly may cause it, or it may start from some inflammation that has attacked the stomach, liver, intestines, or the spleen. When attacked, a slight pain is felt and the animal lies down, stretches himself, sweats freely, and moans. Then he rises, walks about somewhat, and all the time breathes heavy and shows much weakness. The pulse runs up between 75 and 100 beats a minute. In time the legs and ears get cold. A good treatment is a pint of raw linseed oil, 4 tablespoonfuls of laudanum, and 10 drops of aconite. Mix these and give as a drench. A mustard plaster for the abdomen and something hot for the back are desirable. In two hours, if the pain continues, give 4 tablespoonfuls of laudanum and 10 drops aconite in a pint of lukewarm water. Use as a drench. =PINK EYE.=--A contagious epidemic disease of the horse affecting the animal all over and particularly the membranes of the air passages. There is general debility, considerable cough, and a general discharge from the nostrils. The transparent covering of the eyeball becomes inflamed. At times the disease is very fatal, many horses succumbing to it. It is most common in the spring. One of the symptoms is the general weakness of the animal. He hangs his head, and trembles; has little appetite and appears cold. The eyes show a watery discharge and later a stare coat. The pulse at first is weak, but quick, and later rising to 80 or 90 beats a minute. At this stage the temperature is high, around 103 to 105 degrees. The breathing is accelerated to about 50 times a minute. The bowels do not act, or act very poorly, and the urine is very scanty. In treating, first isolate the animal and disinfect the stables to prevent spreading. Any of the common disinfectants will do. Good nursing is necessary. Keep the horse warm with blankets. Give him soft, nourishing food. The eyes should be bathed three or four times a day with hot water. A little boric acid, say, a teaspoonful to a half pint of water, is good to use as a wash for the eyes and nostrils. To keep the kidneys active and to reduce the fever, give a tablespoonful of nitrate of potash dissolved in water two or three times a day. If the horse is very weak, one-half glass of whiskey in a pint of gruel three times a day is stimulating and helpful. It is better not to give any physic of any kind. After recovery, the horse should be given little or no work. A long rest of several weeks is necessary.
