Agents applied directly to the inflamed mucous membrane are often requisite. The air of the building should be rather warm, equable and moistened by water vapor, if that can be conveniently done. Calomel or alum powder may be frequently introduced into the larynx by means of a whalebone prob and sponge as spoken of under laryngitis, or a solution of nitrate of silver (10 grains to the ounce of water) may be applied several times a day. These not only hasten the removal of false membranes but counteract their production. They produce violent and convulsive coughing at first and have to be used carefully. Delafond blew in such agents through an opening made in the windpipe. They may be injected with a hypodermic syringe. In prostrate conditions it may be necessary to resort to stimulants (wine whey, carbonate of ammonia) and tonics (gentian, Peruvian bark). CROUP IN SHEEP. According to Roche Lubin croup is sometimes observed in spring in lambs and hogs. The common cause is “the shutting up of the animals for the whole twenty-four hours in a hot confined place, the floor of which is covered by a fine dust, and the air loaded with the same, owing to the jostling of the sheep together, the effects being intensified by the weight of the fleeces.” The disease is manifested by constant working of the jaws, extreme tension of the neck, abundant salivation, respiration hurried and whistling, extreme pain and threatened suffocation when the slightest pressure is made on the throat, and refusal of all food liquid or solid. The weak, hacking, convulsive cough is associated with the discharge of a whitish glairy mucus by the nose until the third or fourth day when false membranes may be expected. _Treatment_ is like that for the ox, medicine being given in about one-fifth of the doses. CROUP IN THE HORSE. The rare cases of _croup_ in foals and young horses appear due to the same general causes as in ruminants. M. Riss records two cases, and Bouley one from breathing smoke when the straw of the stable had taken fire. The suddenness of the attack, the spasmodic symptoms and the duration of the disease and the treatment do not differ materially from those given for the ox. PHARYNGEAL AND LARYNGEAL POLYPI. Pediculated tumors. Dyspnœa through change of position, operation by ecraseur, snare, or cricoid incision.
