If putrid feed has been consumed, creolin may be administered in doses of 2 drams, mixed with 1 pint of warm water or milk. If there is obstinate constipation and if a laxative must be employed, it should be sweet or castor oil, from 1 pint to 1 quart. _Antidotes for poisons._--For the various poisons the remedies are as follows: Arsenic: Oxyhydrate of iron solution, 1 pint to 1 quart; or calcined magnesia, one-half ounce in 1 pint of water. Corrosive sublimate (bichlorid of mercury): The whites of a dozen eggs, or 2 ounces of flowers of sulphur. Sugar of lead: Glauber's salt, 1 pound in 1 quart of warm water; to be followed with iodid of potash, 3 drams at a dose, in water, three times daily for five days. Sulphate of copper: Milk, the whites of eggs, or reduced iron. Sulphate or chlorid of zinc: Milk, the whites of eggs, or calcined magnesia. Lye or alkalies, as caustic potash or soda: Vinegar, dilute sulphuric acid, and linseed tea, with opium, 3 drams. Mineral acids: Chalk, or calcined magnesia, or baking soda; later give linseed tea and opium. HEMORRHOIDS, OR PILES. These are rare, comparatively, in horses. They are diagnosed by the appearance of bright-red irregular tumors after defecation, which may remain visible at all times or be seen only when the horse is down or after passing his manure. They are mostly due to constipation, irritation, or injuries, or follow from the severe straining during dysentery. I have observed them to follow from severe labor pains in the mare. _Treatment._--Attention must be paid to the condition of the bowels; they should be soft, but purging is to be avoided. The tumors should be washed in warm water and thoroughly cleansed, after which scarify them and gently but firmly squeeze out the liquid that will be seen to follow the shallow incisions. After thus squeezing these tumors and before replacing through the anus, bathe the parts with some anodyn wash. For this purpose the glycerite of tannin and laudanum in equal parts is good. Mucilaginous injections into the rectum may be of service for a few days. HERNIA, OR RUPTURE.
