TRIFICIAL NEURECTOMY 51 



tions needs to be unusually strict in every detail and the anaes- 

 thesia, whether local or general, complete. Carefully avoid 

 wounding the neighboring vessels and control completely 

 any hemorrhage that occurs in order to avoid a blood clot 

 in the wound, which always invites infection. It is of even 

 greater importance, whenever practicable, that as suggested 

 above, the operation be performed first on one side only, 

 and when that has healed operate upon the other. In this 

 way one avoids the critical danger of the infection of the 

 first wound while the head of the horse is resting upon that 

 side during the second operation.
