This is one of the most common diseases of the horse, and which may be said to be due in nearly every case to bad stable management, or bad stables. There is nasal discharge, often fever and cough, with more or less languidity and weakness.

In this condition, the chief treatment consists in careful nursing. A comfortable, well-ventilated stable or loose-box, and clothing the body and legs; moist and warm food, without much corn, are all that is necessary, except it be a little nitrate of potass in the water. If there is constipation, one or two ounces of sulphate of magnesia may be given at intervals, and its action may be supplemented by an enema of tepid water. If the cough is troublesome, stimulating liniment, mustard or its extract, may be applied to the throat. If the breathing becomes quickened, the cough more severe, fever increased, and appetite diminished, a veterinary surgeon should be sent for, as inflammation of the lungs, bronchitis, or pleurisy, is to be apprehended.
