part of general catarrh. But this disease also occurs as an 

 independent affection, from cold, exposure, damp, direct 

 irritation, or disordered digestion. 



Symptoms. — Deglutition is attended with diflSculty, and 

 sometimes with coughing, during which the food is ex- 

 pelled back into the mouth, and liquid through the 

 nostrils. There is no fever or impairment of respiration 

 unless laryngitis is also present. 



Treatment. — Many cases recover in a few days with rest. 

 Inhalation of hot-water vapour medicated with carbolic 

 acid or opium is very useful. 



Gargling with solution of chlorate of potash or sulphur- 

 ous acid may also be tried, and hot fomentations externally 

 are useful in allaying the irritation. 



In chronic cases, stimulating liniments or blisters may be 

 applied. 



POST-PHARYNGEAL ABSCESS.— Simple inflammation 

 of the pharynx may terminate in the formation of abscess in 

 the pharyngeal structures. 



Suppuration in the parts, however, is more frequently 

 met with in the pharyngitis occurring in some of the specific 

 fevers, or in animals which have been exposed to mal- 

 hygienic conditions. Abscess may also occur here as part of 

 a general pyreraia. 



Suppuration in the pharynx causes obstruction to deglu- 

 tition, the breathing becomes difficult, and the throat is 

 generally tender. 



Treatment. — The treatment of pharyngeal abscess is 

 essentially surgical. If the breathing become difficult, in- 

 halation of hot- water vapour, and the hot fomentations ex- 

 ternally, are useful. If the abscess do not burst, it may be 

 necessary to open it, especially if breathing is very much 

 interfered with.
