174 PRACTICE OF EQUINE MEDICINE. 



Outline the indications for treatment. 



Internally, belladonna, strychnine, etc. 

 Locally, blisters over the pharynx; astringent and antiseptic 

 solutions applied to the pharynx itself. 



POST-PHARYNGEAL ABSCESS. 



Give the synonym. 



Super-pharyngeal abscess. 



What is the definition ? 



This is a term borrowed from the human, and signifies a col- 

 lection of pus in the cellular tissue behind or above the pharynx. 



It is rarely seen, although it may occur, and when it is present 

 you are apt to be misled, as the only symptom present is roaring. 



After a time the abscess breaks, pus escapes from the nose, and 

 the symptom subsides. 



What are the indications for treatment ? 



Williams recommends puncturing, but it is often difficult, un- 

 less the abscess points and bulges. If so, treat as you would any 

 abscess. ' If a diagnosis can be made the exploring needle should be 

 employed to confirm it, when it may be opened by boring with the 

 finger or by the use of the aspirator. 



INFLAMMATION OP THE GUTTURAL POUCHES. 



Give the synonym. 



Pus in the guttural pouches. 



Define the same. 



This is a catarrhal inflammation of the mucous membrane of 

 the guttural pouches, with the formation and accumulation of pus, 

 and characterized by a discharge from the nostrils at varying in- 

 tervals, especially if the head be depressed. 



Describe the use of the guttural pouches. 



The use is not well understood; the sense of hearing is sup- 

 posed to be aided by them. 



The pouches are found in the equine race, and are lined by 

 mucous membrane. The opening of the Eustachian tube is high up.
