seen no other complication than abscess formation. De- 

 glutition pneumonia, which might be an expected com- 

 plication, I have never seen occur in company with acute 

 infectious pharyngitis. Neither has the patient, in any 

 case, reqtiired feeding by artificial means. 



In old horses acute infectious pharyngitis may have to 

 be differentiated from senile paralysis of the pharynx. 

 A confusion is only possible, and even then not very 

 probable, in the early stages. In cases of senile paralysis 

 the history is always to the effect that the trouble has 

 been coming on very slowly. For months the horse has 

 shown signs of a deglutition impediment of an obscure 

 character. 



Neither is there any marked degree of pyrexia. In- 

 stead of fullness and tenderness in the pharyngeal region, 

 there is rather a lean throat, and soreness is absent.
