g^ish of pus will immediately escape into the mouth. I own 

 thei-e is some difficulty in the operation, but if nothing be done, 

 tlie animal's life is sure to be sacrificed. 



The operation maybe performed through the guttural pouchea, 

 or the puncture might be made through the nostril, but L think. 

 t]ie best way is that through the mouth. 



COLLECTIONS OF PUS IN THE GUTTUHAL POUCHES 



Differ from post-pharyngeal abscess by the presence of more: 

 or less external swelling; a bulging outwards of the parotid 

 glands ; and by an intermitting discharge from the nostrils of 

 tliick creamy, perhaps sL'ghtly curdled pus. The difficulty in 

 swallowing, although at first perhaps very great, is not persis- 

 tent, disappearing upon the ctjflsation of the pharyngeal inflara-j 

 niation 



The diagnostic signs of pus in the guttural pouches are, 

 fii*st, a discharge from either one or both nostrils when the head 

 is depressed, or an occasional nasal discliarge, as from an over- 

 How through the openings of the eustachian tubes ; a swelling 

 more or less extensive, without hardness, on the side affected, 

 witli a flow of pus from the uosb'il when the swelling is pressed 

 Vpon. 



Tiis 2'reatment. — Cut through the skin immediately behind 

 the posterior border of the parotid gland, above the carotids and 

 jugulars, the incision is to be at least two inches long ; after dis- 

 secting carefully through the thin superficial layer of muscular 

 tissue, and exposing the edge of the gland, the finger is to be 

 introduced into the very loose areolar tissue situated beneath it, 

 and pushed until the wall of the guttural pouch, or envelop- 

 ing capsule of the pus is felt ; an effort is now to be made 

 for the purpose of overcoming it by the pressxire of the finger. 

 Sometimes it will give way, but if not, a canula is to be intro- 

 duced into the space made by tlie finger, through which the 

 sac is to be punctured by the stillet, and the whole cavity 

 w.\shed out with warm water, forced in by the elastic sj'phon. 

 The wound must afterwards bo kept open by plugs of toAV, 

 and the parts thorouglily washed daily with water containing 

 caibolic acid or some asti'ing.'iit^ using tho syphon in ordiir to do 

 it effectually.
