The most valuable purgative for the horse, hut not to he depended on for cattle and sheep. A horse requires from 4 to 8 dr. of Barhadoes aloes, from 5 to 9 dr. of Socotrine, and from 6 to 10 of Cape. Mr. Youatt says 3 dr. of Barhadoes are equal to 4 of Cape aloes. Mr. Morton considers a mixture of equal parts of Cape and Barhadoes aloes to he quite as efficacious as the latter alone. But the fine gourd Barhadoes aloes are the most certain in their operation. If the animal he prepared by previous mashes, 5 dr. are generally, and 6 dr. almost always, sufficient. Mr. Blaine recommends 2 dr. every 6 hours till 8 dr. have been taken, as a nauseant and purgative; but Mr. YOUATT strong disapproves of this plan, particularly in inflammation of the lungs. Aloes require from 18 to 36 hours to produce their effect, during which time the horse should not be ridden far or fast. Though not to he depended on for cattle, 4 to 6 dr. are sometimes added to the purgative salts. Large doses (in some cases sufficient to destroy life) have been given to sheep without purging. Small dogs require from 15 to 30 gr.; medium-sized ones, a dr.; some larger ones require 2 dr., or more. Hogs can bear hut a few grains. Externally, in the form of tincture, aloes is used as a stimulating application to wounds. Mr. Finlay Dux says: "The administration of aloes should be avoided in cases of irritation or inflammation of any part of the alimentary canal, and in piles or hAemorrhage from the rectum. In bronchitis and other inflammatory affections of the mucous membranes, and in inflammation of the kidneys, it must be used with great caution, and in very small doses, for in such cases the intestinal mucous membrane is usually irritable, and superpurgation and inflammation are readily induced. During pregnancy, both in the mare and the bitch, the violent operation of aloes must be carefully avoided. Some practitioners give it both to foals and calves, but for young animals, linseed oil or castor oil is more suitable."
