This is a special form of catarrhal influenza, known by the various names of influenza, pinkeye, epizootic, epizootic cellulitis, etc. This, like the other distempers, seems to be contagious, either by direct contact or by the infection carried in the atmosphere.

Symptoms. - Dullness; loss of appetite, a short cough, a dry, hot mouth, eyes somewhat inflamed and watery ears and legs cold, pulse rapid but weak, and the throat sometimes swollen and tender to the touch. If the disease runs for some time without treatment it often becomes complicated with pneumonia, rheumatism, or some other disease; it then becomes more serious and must be treated according to the instructions given elsewhere for the treatment of such diseases.

Treatment. - First of all the animal should be placed in a clean, well-ventilated box stall, and clothed according to the weather. The food should consist of bran mash, boiled oats, and any other laxative, digestible food the animal will eat. A little sweet hay should always be within reach; also a pail of clean, fresh water. As there is great danger of strangulation in drenching, because of sore throat, all medicines should be given either in the water or by placing it on the tongue. A drachm of nitrate of potash should be given three times a day in the first stages of the disease; but if the patient becomes much debilitated the potash should be discontinued. From a half to one ounce of sulphite of soda should be dissolved in the drinking water during each twenty-four hours. If there is much weakness an ounce of spirits of nitre should be diluted and given with a syringe three times a day; and, if there is much difficulty in breathing, half an ounce of fluid extract of lobelia may be added to each dose. The throat should be rubbed several times a day with turpentine, oil, and ammonia, in equal parts, until the skin gets sore. The legs should be well rubbed with the hands or wisps of hay, then bandaged. The treatment should continue until the horse is entirely well.
