A good deal of open air exercise must be given, not violent, but gentle and long continued, and this though the patient may appear physically unfit for it. Exercise should be given three hours or more after a full meal. Purgatives (one ounce castor oil) should be administered twice a week. A clean bed, not too soft nor luxurious, should be allowed in a dry, airy place. The skin should be well brushed daily and occasionally washed thoroughly with soap, care being taken to dry the coat completely afterwards. Sedatives should be given daily, such as a half grain each of stramonium and tartar emetic, and in advanced stages with weakness and emaciation vegetable tonics will be demanded. Blaine strongly advocates a course of emetics, given every alternate day, and Mayhew lauds frequently repeated ammoniacal blisters to the sides. Such measures will be especially applicable when there is irritation and discharge from the bronchial mucous membrane. Strong subjects can alone, however, bear such treatment. All cases of asthma in the dog are obstinate and critical and require much judgment in treatment. ASTHMA IN THE HORSE. Hering records a case of _spasmodic asthma_, in a strong cart horse. Besides the oppressed and difficult respiration, the animal was excessively dull and had no appetite, but the pulse was almost of the natural standard. The animal was not benefited by opening medicine but improved under active doses of extract of hyoscyamus. Quillaume reports two asses attacked apparently in the same way, and Delwart and Robertson refer to other cases. They recovered under antispasmodics. These are at least closely related to heaves, which is largely a neurosis at first. ASTHMA. BROKEN WIND. HEAVES. DYSPNŒA.
