 maxillary sinuses were then trephined and thoroughly 

 cleansed by turning the hose into them. After 

 removing all the pus the sinuses were treated with 

 injections of carbolized water containing a small 

 amount of common salt. These dressings were 

 repeated daily for six weeks, at which time the 

 horse was sent home much improved. The im- 

 provement continued until complete recovery took 

 place. 



This horse had a carious tooth extracted the 

 previous September and was at that time also suffer- 

 ing from a discharge from the nostrils. Had the 

 sinuses at that time been trephined so as to allow 

 the pus to escape, the latter trouble would undoubt- 

 edly have been avoided. 



If there is a fetid discharge from the nostril, due 

 to a carious tooth, it is always advisable to trephine 

 the sinus at the lower border, and as nearly opposite 

 the diseased tooth as possible. The sinus should 

 then be cleansed and afterward dressed with carbol- 

 ized water, one part of the acid to thirty or forty of 

 soft water.

 there is a fetid discharge from the nostrils, due to 

 carious teeth producing ulceration of the sinuses.
