TREATMENT AFTER TREPHINING. 159 



the maxillary sinuses, and the frontal also, had suffered 

 the transformation already described to its greatest 

 degree. And, finally, it required efforts almost beyond 

 belief to loosen the tooth and force it from its socket. 

 Still the animal made a good recovery.

 solution of soda, mixed with a gentian wine, should be

 passing from the mouth to the sinus. The regimen 

 should consist of gruel only, the gargles to be used 

 often during the day. 



" On the second day the borders of the sinus will be

 cauterized membrane ; the eschars detach themselves, 

 exposing a rosy surface of favorable aspect to the view. 

 The odor is less repugnant. Continue the aromatic 

 detergent injections, the same food, with the addition
