He who is desirous of ascertaining whether there is any disease in the larynx of a horse, should apply his ear to the lower part of the windpipe. If he finds that the air passes in and out without interruption, there is no disease of any consequence, either in the windpipe or the chest, for it would be immediately detected by the loudness or the interruption of the murmur. Then let him gradually proceed up the neck with his ear still upon the windpipe; perhaps he soon begins to recognize a little gurgling sound. He can have no surer proof that there is the seat of the disease. TREATMENT--REMEDY. The treatment here is very plain: Blood must be copiously extracted from the jugular vein, which must be done quickly, letting it run until the pulse begins to flutter, then administer the fever medicine: 1 drachm digitalis, 1½ “ emetic tartar, 3 “ nitre, ½ ounce aloes, Which must be repeated twice or thrice in the day. Aloes may be safely given at this stage of the disease, because the chest is not yet implicated. To this must be added immediately a blister, and a sharp one. EPIDEMICS. In epidemics all offensive matter should be immediately and carefully cleared away, and no small portion of the chloride of lime used in washing the stables, troughs, &c., and particularly his ulcers, &c. CHRONIC COUGH. If a harsh hollow cough is accompanied by a staring coat; it proceeds from irritability of the air passages, which will be discovered by the horse coughing after drinking, or when he first goes out of the stable in the morning, or by occasionally snorting out thick mucus from the nose, medicine may be given with advantage to diminish the irritation; generally small doses of digitalis, emetic tartar and nitre administered at night. Take Digitalis ½ drachm, Emetic tartar 1 drachm, Nitre 1 drachm. This should be mixed into a ball with tar and given every night regularly for a considerable length of time. A blister extending from the root of one ear to that of the other, taking in the whole of the channel and reaching six or eight inches down the windpipe has been tried with good effect. Feeding has much influence on this complaint: too much dry meat, and especially chaff increases it; carrots afford decided relief. THICK OR BROKEN WIND. There is no remedy for the cure of this but it may be improved. The horse should have full proportions of solid food, but very little hay, and no chaff; he should not be worked immediately after a heavy meal; water should be given in moderate quantities, but the horse should not be suffered to drink as much as he likes until the day’s work is over; green meat will always be serviceable, and carrots are particularly useful.
