From exposure to wet and cold; sudden changes of weather; turning the horse into a cold, wet place, or bringing him from grass to a warm stable; standing in a draft of cold air, or washing the warm, sweating skin and not drying it afterwards, an inflammation of the bronchial tubes and minute air-cells takes place, meriting the name of BRONCHITIS. SYMPTOMS.—The disease generally begins with a slight cough, quick breathing, sore throat, low spirits, dislike of food, slight discharge from the nostrils, pain of the throat when pinched, and some difficulty of swallowing. In some cases, it comes on suddenly with shaking; the legs, ears and muzzle are at one time hot and at another cold; the skin is rough and staring; the head hung down; mouth hot; the animal remains standing, and does not wish to move; pulse is full and quick; the cough short, frequent, and irritating; the breathing quick and difficult; the eyes and nose red, and rattles are heard in the windpipe at the breast. A profuse discharge of matter from the nostrils indicates the period from which improvement commences. TREATMENT.—Give fifteen drops of A.A., and E.E., alternately every three hours, beginning with A.A. After a day or two, as the animal improves, the intervals between the doses may be prolonged to four or six hours. Keep the animal well covered and protected until recovery takes place. After the feverish symptoms have disappeared the E.E., may be relied upon. STABLING AND FOOD.—In all cases of serious disease of the lungs or air-passages, the horse should be placed in a large, roomy stable or stall, into which the fresh air may freely come, but all damp draughts of air excluded; all dung, damp and dirty straw carefully removed; spread clean straw on the floor; blanket him according to the season, the state of the weather, and skin; hand-rub and flannel bandage the legs every night and morning, or oftener if necessary. For food, bran mashes, gruel, and tempered water only; when recovering, malt or bran mashes, boiled oats, turnips, carrots, and green food, if in season. Inflammation of the Larynx, Laryngitis The larynx is the upper portion of the windpipe, and inflammation of it sometimes occurs and is very dangerous. It is not often unmixed, but is generally accompanied with, or is an extension of, cold or bronchitis, and its causes are the same. It is sometimes a dangerous disease, and may kill by suffocation or degenerate into bronchitis, or pneumonia. It is recognized by the difficulty of respiration, WHICH IS LOUD AND HEARD AT A DISTANCE.
