_Treatment._ Beside the general measures advised for catarrhal pharyngitis, this type demands especially measures to moderate the intensity of the suffering, and when abscess appears inevitable to hasten its maturation. The first demand is met by hot fomentations persistently applied to the throat. This may be done by spongio-piline, or simply by well washed wool or cotton bound upon the throat and wet at frequent intervals with water rather hotter than the hand can bear. The addition of a little carbolic acid will secure at once some local anæsthesia and a measure of antisepsis. In warm weather the substitution of cold water has been resorted to with apparently good effect. If adopted it should be frequently removed so as to keep up the constant action of cold and moisture. These have been especially recommended in dogs injured by a tight or ill-fitting collar. When suppuration appears imminent as shown by the dense, hard, circumscribed phlegmon, stimulating embrocations may be used to hasten its progress. Camphorated spirit is suitable for carnivora and sheep. It may be combined with tincture of cantharides for horses. For cattle and swine, oil of turpentine may be added, the three being used in equal proportions. A liniment of ammonia and oil may be used more or less frequently and energetically according to the relative thickness and insensibility of the skin of the animal affected. When matter has formed and fluctuates, it should be at once evacuated and the cavity treated by antiseptic dressings. In this way secondary abscesses, septic infections, molecular ulcerations and other injurious sequelæ may be largely obviated. In case of threatened asphyxia the _dernier resort_ of tracheotomy is always available, and this often acts very favorably in improving the æration of the blood, in restoring the flagging vital functions which depend on hæmatosis, and in removing the friction and irritation consequent on the passage of air through the narrowed and tender passages. SUPRA-PHARYNGEAL (RETRO-PHARYNGEAL) ABSCESS. A sequel of phlegmonous pharyngitis. Symptoms; masked by its depth; pharyngeal wheezing or roaring with little local swelling; difficult swallowing; resisting tissues tend to chronicity. Results; pharyngeal fistula, burrowing along œsophagus, rupture into chest or blood-vessels, lymphadenitis, compression of vagus, or jugulars, permanent infected cavity with small orifice. Diagnosis from pus in guttural pouches. Treatment; external opening; antisepsis. This is a natural result of phlegmonous pharyngitis, but it is possessed of so great importance alike in its chronicity and its results that it seems to deserve a special article. Like its initial morbid condition it is especially common in the soliped, and like that may be traceable to strangles, influenza, and local traumatism.
