    noclules may be deep seated, so that they can not be discovered by examining the surface of the tongue, but iu this situation, instead of producing ulceration and destruction of the mucous membrane, they set up inflammation in the muscular structure of the tongue, which terminates in a marked enlargement and wood-like induration of that organ, which has led to this disease being commonly called “ wooden tongue” in Germany. The enlarged and indurated condition of the tongue is a great impediment to the animal masticating its food, so that if the tongue is extensively affected the animal soon becomes emaciated. Similar nodules may form on the inner surface of the cheeks, of the lips, on the surface of the palate, and even in some instances on the mucous membrane lining the nose. Treatment.—When the nodules are large they may be dissected out or scraped out, so as to leave nothing but healthy tissue, and afterwards dressed with tincture of iodine. When this procedure is not practica- ble an incision should be made into the nodule, which should then be injected with tincture of iodine. This treatment destroys the micro- scopic fungus contained in the nodules, and will consequently prevent its spreading and bring about its ultimate separation from the healthy tissues. It is obvious that to treat this disease successfully its nature must be recognized at an early stage. After the muscular portion oi the tongue has become enlarged and indurated it will not be possible to restore it to its healthy condition. [Quite recently actinomycosis of the tongue has been treated with great success in Europe by the administration of iodide of potassium. According to Nocard, this drug given once or twice a day, in doses of lb drams dissolved in a pint of water, acts as a specific and is followed by rapid improvement and the permanent cure of the affected animal. The results reported are so extraordinary that they justify the trial of this remedy in all cases of actinomycosis in the tongue or other organs. D. E. S.] DISEASES OF THE PHARYNX AND GULLET. PHARYNGITIS—SORE THROAT. This is an inflammation of the mucous membrane lining the pharynx. It is frequently associated with laryngitis and bronchitis, and sometimes with pleurisy. Symptoms.—The muzzle is dry, the saliva dribbles from the corner of the mouth5 the animal either does not swallow or swallows with diffi- culty; occasionally the liquids which it attempts to take come back in part through the nostrils, and the animal holds its neck in a stiff, straight position, moving it as little as possible. The eyelids are half closed, the white of the eye is bloodshot, and the animal occasionally grinds its teeth. When it attempts to eat hay or grass, after masticat- ing the food the animal drops it out of its mouth as if to avoid the
