From rinderpest it is differentiated by the fact that the sores on the mouth (when present) are not of the nature of epithelial concretions, and they do not appear on the vulva, and more significant still there is no indication of the introduction of the disease by contagion nor of its rapid progress from herd to herd. The immunity of sheep from gangrenous ergotism is another significant feature. _Prevention_ consists in putting a stop to the supply of the altered food or, if it must be given, in giving it in small quantities only with abundance of water or fresh succulent aliment. In the case of grains or marcs the fermentation may be checked by adding ¼ per cent. of common salt and packing the material firmly in a close box or silo. In ergotism, succulent food, water ad libitum, stimulants, poultices, fomentations or wet bandages, a warm building and pure air are all important. Usually ergot and smut can be safely fed in relatively large amount with a liberal ration of potatoes, turnips, beets, green food or ensilage. _Treatment_ does not differ materially from that advised for the horse. Antiferments including potassium iodide, and saline purgatives stand at the head of the list. Stimulants may be demanded to rouse the torpid bowels and nervous system and unless contraindicated by gastro-intestinal inflammation oil of turpentine offers itself as at once stimulant, antiseptic and eliminating. Injections and counter-irritants are of use. Then cold (ice, snow, water) to the head, and the confinement of the patient so that he cannot injure himself or others are not to be neglected.
