_Treatment._ The first object must be the removal or neutralizing of the poison. In some instances the stomach pump or tube might be tried. Usually one must fall back on antiferments such as naphthol, naphthalin, salol, salicylic acid, and above all iodide of potassium. The last checks the growth of the fungi or bacteria and favors elimination of the toxins. It may be given freely to act on the kidneys. Creolin, 1¼ drachm, repeated three times a day has been found effective (Albrecht). In addition the action of the bowels may be solicited by full doses of sulphate of soda and abundance of water. When the brain is implicated Cadeac recommends bleeding as an eliminating as well as a sedative measure. In any case use cold water, snow or ice to the head, elevation of the head, and purgatives which may as a rule be doubled. Potassium iodide or other antiseptics should be pushed, and diuresis as well as a relaxed condition of the bowels maintained. Counter-irritants such as mustard may be applied to the abdomen, and enemata used at frequent intervals. It is important to fix the patient to a ring in the centre of a box stall or barn to keep him from injuring himself. CRYPTOGAMIC POISONING IN RUMINANTS.
