24 SPECIAL EQUINE THERAPY 



suiting in the evacuation of the characteristic rusty-col- 

 ored fluid, establishes the ciiagnosis of myxoid degenera- 

 tion. 



There is no doubt that, under proper treatment, the 

 bone which has disappeared would be regenerated, al- 

 though the effect of this regeneration of bone might fall 

 short of expectations. 



ACUTE INFECTIOUS PHARYNGITIS 



In taking up the discussion of this subject I would 

 begin with the statement that I am aware that some 

 authors of works on equine medicine believe this to be a 

 localized manifestation of influenza. A form of acute 

 pharyngitis does occur during some outbreaks of influ- 

 enza. I am positive, however, that the authors in ques- 

 tion are in error when they classify all forms of acute 

 pharyngitis of an infectious and transmissible character 

 Sunder the head of influenza. We have in the United 

 States a form of acute infectious, contagious pharyngitis 

 in horses that occurs as a disease per se, unaccompanied 

 by lesions which could bring it recognition as a manifes- 

 tation of influenza. 



The disease under discussion here occurs in an enzootic 

 form as a rule, although during some seasons it has as- 

 sumed almost epizootic force. It affects both young and 

 old horses, without regard to condition or individual en- 

 vironment, and runs a typical and almost exact course 

 in aU cases. This is its flrst feature of differentiation 

 from acute pharyngitis resulting from a localized influ- 

 enza infection. Hardly two cases of the latter form 

 appear similarly, while the disease which we have under 

 discussion runs in every instance a typical, characteristic 

 course.
