Medicines which increase the flow of urine. Some of them, juniper, capivi, squills, broom, etc, appear to carry off water only; while the alkaline salts remove solid matters also, and thus purify the blood. Diuretics are employed to lessen the quantity of the circulating fluid in fevers and inflammations. The legs of many horses cannot be kept fine, nor the grease be subdued without the use of diuretics. Plenty of water should be allowed with them. But their too frequent use is injurious.


It is emetic to dogs.

Dover's Powder

Sudorific to cattle, in rheumatism. Dose, 1 dr.


Nutritive and demulcent. Sometimes given in diarrhoea. They constitute the best antidote to poisoning by corrosive sublimate.


It has little effect on the horse.


An infusion of the flowers is given in catarrhal complaints. The leaves boiled with lard form an emollient ointment, which is a common application to sore udders. The fresh leaves of the dwarf elder are given (according to Bourgelat and Moiroud) with some success as a deobstruent and aperient, in swelled legs, dropsy, and farcy.

Epsom Salt

A cooling laxative. It is not to be depended on as a purgative for the horse; but in doses of 4 or 5 oz., in a large quantity of water, repeated three times a day, it is useful as a laxative and diuretic in inflammatory diseases. Cattle require from 12 to 20 oz., with ginger or any of the warm seeds. It is sometimes rendered more active by aloes or gamboge. Calves require from 1 to 2 oz., according to their age and strength. Sheep, 1/2 oz. to 2 oz. Dogs, from 1 to 3 dr. wrapped in tissue paper. A large elephant takes a pound and a half, preceded by a dr. of calomel. - Youatt.

Ergot of Eye

Styptic in haemorrhages of the lungs, kidneys, and other organs. It promotes parturition. Dose for a mare, 2 or 3 dr. A cow, 2 dr. repeated at intervals of half an hour. An ewe, 20 to 40 gr. ' Bitch, 5 to 10 gr. [Mr. Spooner says from 2 to 4 gr.], or an infusion of a scruple given at three times, at intervals of half an hour. Larger doses than the above are indicated by M. Moiroud.


Remedies which excite a discharge from the nostrils.


Caustics. Substances which destroy the surface to which they are applied.


A diffusible stimulant and antispasmodic; used chiefly in colic. Dose, 1/2 oz. to 3/4 oz.; cattle, 1/2 oz. to 1 oz.; dogs, 7 to 14 drops. It is used outwardly in cooling lotions and eye-waters. The vapour, inhaled by means of a proper apparatus, produces insensibility to pain; but some of the experiments with this agent have proved most unfortunate. Chloroform has almost universally supplanted it as an anaesthetic.
