_Prevention._ The first object must be to destroy the infection, and the second to obviate the susceptibility of the young animal. The clearing away of all accumulations of litter, filth, and even fodder from the stable proper, including the stalls where the dams lie, should be followed by a thorough whitewashing or disinfection, with sulphate of copper or of iron, or even mercuric chloride, (1:500.) If the disease has already appeared in a stable the calves should be penned singly to avoid the possibility of infection through sucking each others navels. In all cases an antiseptic (tannin, carbolic acid) should be applied to the navel of the new born. The food of the dam and nurse should be nutritive and free from any suspicion of mustiness or decomposition, and when possible the calf should be allowed to draw its own milk from the teat. When this cannot be allowed, artificial feeding should be surrounded by all the safeguards, named under acute indigestion of calves. _Treatment._ Cadeac strongly recommends ½ oz. common salt daily with the food, or alcohol ¾ oz., or a strong infusion of coffee mixed with the milk. Lenglen advises quinoa in the form of tincture, ½ to 1 oz. McGillivray sulphate of soda. Tincture of chloride of iron 30 drops in an ounce of water with each meal would be an excellent resort. _Locally_ antiseptics are our main reliance. Naphthol, naphthalin, salicylic acid, or salicylate of soda, may be applied directly to the diseased mucous membrane. Tincture of chloride of iron in water (1:2) is one of the best agents (James). Carbolic acid 1 drachm in 6 oz. water, and 1 oz. alcohol has been used safely and with excellent results (Lenglen). Like most other antiseptics, however, this latter must be used with caution as regards the amount. No actively poisonous antiseptic is admissible. The antiseptic should be swabbed over the whole interior of the mouth after each meal. In case of deep gangrenous masses excision and antiseptics are demanded.
