SYMPTOMS.—In some cases it comes on slowly; the horse is dull and sleepy; rests his head on the manger, or places it against the wall or between his legs, and falls asleep. In this state he will, perhaps, stagger and almost fall to the ground; he, however, wakes up, stares about him, takes a mouthful of hay, chews it slowly, and ere long is again dozing or fast asleep. The eyelids are nearly closed; the eyes and nose red; the pupils dilated; the bowels bound, and pulse slower than in health. This is the congestive stage, and may continue until the animal recovers or dies; but, in general, other symptoms appear to which the name Mad Staggers may be more appropriately applied. In such cases the pulse rises; the breathing is quickened; the nose and eyes are very red; nostrils widened; the eyes have a wild, fierce look; the feet are stamped, as if in passion; he plunges about the stall, rears upward, strikes out with his fore-feet, and falls backward upon the ground, where he lies panting and covered with sweat; his eyes are thrust forward out of their sockets, and rattles are heard in the throat. Towards the end these violent paroxysms are repeated from time to time, and it is very dangerous to approach or go near him. At last, he is so weak and prostrate that he cannot rise, and amidst convulsions, strangling, foaming at the mouth, sweating, and panting for breath, the animal dies. TREATMENT.—The treatment will not be difficult, or the result doubtful, during the congestive stage; but in the fully developed or phrentic stage, quite so in both respects. The A.A., is the principal dependence, and a dose of fifteen drops may be given every two or three hours, at first, and as the horse improves, the intervals may be somewhat prolonged. Continue this treatment steadily and without deviation. During the paroxysms, the medicine may be given by means of a small glass syringe, or the Medicator used in a similar manner. After the more intense symptoms have passed over, some doses of J.K., alternately with that of A. A., will be of value, giving one in the morning and the other at night. _Concussion of the brain_, inducing symptoms and a condition not essentially varying from the above, requires the same treatment, together with such external applications as the wound may require. Tetanus, or Lock-Jaw This disease is more common in the horse than in other domestic animals. It consists of a muscular spasm of the jaw (whence its name), which usually from thence extends to all the muscles of the body. It always occurs in consequence of an injury or wound, such as broken knees, open joints, severe bruises, nicked or docked tail, castration, wounds of the feet, prick of a nail, or even the galling of a crupper, through which opening the tetanus germ enters the body. The germ of tetanus flourishes without air (anaerobic) and, outside of the body, lives in soil and manure.
