_Lesions._ The congestion is intense and may invade the mouth, nose, pharynx, larynx and bronchia, with at intervals the patches of yellowish white false membranes. These may be soft and diffluent when recent, and tough and resistant when of longer standing. The deeper layers are often bloodstained. Preitsch has seen them extend to the gullet, paunch and manifolds, and attended with considerable ulceration of the subjacent mucous membrane. _Treatment._ This does not differ materially from that recommended for the horse. Among the additional antiseptics employed have been, iodoform, oil of turpentine, sulphide of calcium, silver nitrate and coal tar. To loosen and detach the false membranes ipecacuan and sulphates of soda and magnesia have been largely resorted to. Papayin and pepsin might be tried. Also as anodynes digitalis, morphia, aconite and belladonna. Finally tracheotomy has been employed when asphyxia seemed imminent. PSEUDOMEMBRANOUS PHARYNGITIS IN SHEEP. Cause; infected dust on susceptible subject; inoculation. Symptoms; movement of jaws; frothy lips; salivation; viscid nasal discharge; difficult swallowing and breathing; swollen tender throat; extended head; anorexia; cyanosis; open mouth; cough expels shreds of false membrane; asphyxia. Lesions. Treatment; Glauber salts or muriatic acid in water; antiseptic fumigation and drinking water; antisepsis of the pharynx. Roche-Lubin speaks of this disease as common in flocks, as the result of moving them around for twenty-four hours in a narrow enclosure covered with dust which is raised in a cloud and settles in the fleece so as to increase its weight. The fever and excitement caused by the constant driving and the local action of the infected dust on the respiratory mucous membrane is said to bring about the intense exudative inflammation. It has been seen especially in the spring in young lambs shortly after weaning. Damman claims that he transmitted the disease to sheep by inoculating the diphtheritic exudate of the calf.
