Apomorphia, tartar emetic, turpentine or benzoin may be employed or even pilocarpin, care being taken not to increase prostration unduly. Compressed air, oxygen and peroxide of hydrogen will sometimes relieve. With the advent of expectoration, or earlier, iodide of potassium in one drachm dose, thrice a day will do much to obviate glandular and other enlargement which would tend to develop _roaring_. The diet should be laxative, non-stimulating and somewhat spare. Mashes of wheat bran, boiled linseed or boiled barley; roots such as turnips, carrots, beets; in summer a limited supply of fresh grass, with little hay at any time and that scalded, may indicate the nature of the aliments to be used. As a beverage chilled fresh water or linseed tea may be supplied _ad libitum_. Should the nasal discharge manifest no disposition to cease at the end of 15 or 20 days, as will sometimes happen in young horses, stimulants and tonics must be employed. Gentian (4 drachms), Sulphate of iron (2 drachms), Arsenious acid (5 to 10 grains) or nux vomica (1 scruple) may be given daily as ball, electuary or powder. A full and nutritive diet should at the same time be allowed, and open air exercise enjoined. CHRONIC BRONCHITIS IN THE HORSE. BRONCHIAL CATARRH. As Sequel of Acute: as result of unhygienic environment, diet and usage. Symptoms, breathing accelerated, double expiratory act, short breath, cough husky, or paroxysmal, excited by cold air, water, discharge white flocculent. Percussion, drum-like patches; Auscultation mucous and sibilant râles. Lesions, thick mucus, pale membranes, bronchiectasis, emphysema, ulceration. Thick wind. Treatment, stimulating, tonic, derivative, medicated vapors, careful diet. Tar water. This may be a sequel of the acute form, or it may appear at once as a catarrhal discharge from the bronchial tubes and without any very marked febrile affection, in animals debilitated by damp stables, overwork and a faulty regimen and diet. _Symptoms._ Respiration accelerated, and expiration effected with a double lifting of the flank; the horse is easily blown when moderately exercised; the cough is frequent, soft or rattling and paroxysmal—sometimes hard and deep—is excited when brought from the warm stable into the cold air, and is followed by a whitish, flocculent, purulent discharge from the nostrils, consistent but not sticky (like buttermilk). The pulse is rapid and small in volume. Percussion manifests a healthy resonance over the greater part or all of the chest, a drum-like sound over given areas, and auscultation over its median part detects a bronchial rattle and in most cases a dry sibilant râle.
