From toxic gastro-enteritis it is distinguished by the absence of any history or lesions showing the ingestion of a poison and by the concentration of the lesions on the large intestines whereas in poisoning with irritants, the stomach and small intestines are the most liable to suffer. _Prevention._ Precautions against overcrowding on board ship in hot seasons, and the maintenance of cleanliness are prime considerations. In commissariat herds close crowding must be avoided, feeding should be done at different points for six or eight cattle at each, the yards should be frequently changed, or carefully cleared of manure and sprinkled with a solution of 3 per cent. sulphuric acid. In case an animal is attacked it should at once be removed and killed, and its offal and the yard where it has been, disinfected. Food and drinking water should be specially wholesome. _Treatment._ Mild cases may be successfully treated by the use of mucilaginous draughts, (boiled flaxseed, mallow, slippery elm, gum arabic) with antiseptics (salicylic acid or salicylate of soda 2 to 3 drs., salol 1 dr., creosote 1 dr., sulphate or chloride of iron 1 dr.) every three hours. In the more severe cases the most varied treatment has been resorted to. Formerly opiates and astringents were largely employed, practically shutting up the poison in the intestine. Ipecacuan in large and frequently repeated doses had the advantage of soliciting the action of both liver and bowels, but however useful, it has gradually declined in public confidence. An eliminating and antiseptic treatment has at present the most general acceptance. Seven grains of calomel has been given every two hours for two or three days in succession. Still more recently 2 to 4 ozs. sulphate of soda every three hours with hot water and antiseptics (salicylates, sulphites, salol, boric acid, creolin, naphthol) have been substituted. Even more important is the washing out of the large intestine by antiseptic enemata. These should be very copious and frequently repeated so as not only to render the contents of the rectum and colon antiseptic but to secure the discharge of the offensive matters as they are produced. The agents may be glycerine, carbolic acid, creolin, sulphate of iron, nitrate of silver, salicylic or boric acid. If the animal can be made to stand on an inclined plane with its hind parts elevated it will favor the penetration and retention of the liquid. Perfect rest is a most important accessory. In case of recovery the return to ordinary diet should be gradual. CATARRHAL ENTERITIS IN SHEEP AND GOAT.
