TREATMENT.—Almost every medicine in the pharmacopoeia has been tried in the treatment of tetanus, certain remedies meeting with great success in the hands of some practitioners, and proving total failures in the hands of others. It is, however, generally admitted by the members of the profession that perfect quietness is of greatest importance in the treatment of tetanus. Place the patient in a dry, well ventilated, loose box stall, slightly darkened, if possible, in an out-of-the-way place, and fill the ears with cotton-wool. Administer a full dose of purgative medicine (aloes eight drams) and follow with belladonna in a capsule or bolus. The body should be lightly clothed, and the animal placed in slings. Never give drench if it produces excitement. When the wound can be discovered, powerful antiseptics should be continually applied to its lowest depths. Arsenious acid, chloroform, hyoscyamus, digitalis, belladonna, chloral hydrate, morphine, potassium bromide, carbolic acid, and many other medicines have been used, and some of them have been found beneficial. Belladonna is probably as good as any, and should be given freely. Inhalations of chloroform temporarily abate spasm, but the reaction afterwards is usually severe. Medicines which can be given in the drinking-water may be administered in that way. The food should consist of milk, eggs, beef-tea, wine gruel, and food of that description, easily taken and of a very nutritious character. Too great care or attention cannot possibly be bestowed upon the animal. The after-treatment consists of allowing a liberal quantity of good nutritious food—green food is preferable. Exercise daily for some time after recovery has taken place, and the work should be light and slow for a month or two. PREVENTIVE TREATMENT.—An antitoxin serum, if injected under the skin of a patient before a surgical operation, or immediately after the infection of a wound, is a most reliable safeguard against tetanus. It should always be used in districts where tetanus is prevalent. Its value subcutaneously is solely preventive, not curative; and it is of no use when once the disease has gained a foothold. LUNG FEVER. (_Pneumonia_) CAUSE.—Predisposition is largely accountable for this disease, which is more common to young horses than old; also, changes of temperature, introduction of foreign bodies or liquids into the trachea (windpipe) and the bronchial tubes, inhalation of smoke or irritating gases, excitement, exposure to cold after clipping, turning out to pasture from a warm stable, or injury to chest or ribs from being struck with a pole, etc.
