of a little bran, and gargle often. As suppuration be- 

 gins to establish itself, the dressings should be renewed 

 two or three times during the twenty-four hours. 



" It is not our intention to indicate the progress of 

 the wound and the attention it demands from day to 

 day. The tumefied bones and other structures in the 

 region of the wound proportionally lessen, and the 

 membrane of the sinus takes on a uniformly rosy tint 

 and the glistening, humid aspect proper to a mucous 

 membrane. The nasal flux finally ceases, the matter 

 that may be secreted finding an outlet through the 

 alveolus into the mouth. The opening made by the 

 trephine contracts itself by degrees, but in extreme 

 cases, like the one we have described, it is never suffi- 

 cient to entirely repair the structures cut away. It 

 may be hidden, however, by a leather or metallic plate, 

 attached to the check of the bridle." 



The surgeons claim that the resort to this severe 

 mode of extracting teeth is justified by the success of 

 the operation and its concomitant results, namely, the 

 advantage of injecting the sinuses and preventing un- 

 healthy secretions by them, and the stopping of the 

 discharge from the nose, which had aroused suspicion 

 of glanders. They further say and a better argument 

 in favor of veterinary dentistry could not well be ad- 

 vanced that they believe glanders is often caused by 

 the neglect of diseased teeth, and "that the modus 

 operandi of its production in such cases may be ex- 

 plained on the ground of the absorption of pus by the 

 constitution." 



Of trephining the sinuses they further, say: 



" We have treated many cases of caries successfully 

 by simply trephining the frontal and maxillary sinuses
