184 THE DENTISTRY OR TEE TEETH. 



a C} T sfc, about the size of a walnut, in the maxillary 

 sinus. It contained limpid fluid, and occupied the 

 space immediately over the root of the fourth grinder 

 tooth, which was decayed and quite loose, and below * 

 the level of the other teeth. The teeth of the lower 

 jaw appeared healthy." 



Without further examination, Surgeon Smith sent 

 the head to the editor of "The Veterinarian," who 



"The mare (that being the sex according to the 

 teeth) we should take to have been about twenty years 

 old. Her incisors are sound, and so are the grinders 

 of the lower jaw. But in the near (left) upper jaw, 

 the second, fourth, and sixth teeth are in a state of 

 progressive decay, and the same is true of the fourth 

 tooth of the off side. The vacuity caused by the de- 

 fective last grinder has opened a passage to the an- 

 trum, through which the food has passed, and thence 

 into the near chamber of the nose, between the tur- 

 binated bones, where it was discharged through the 

 nostril. This accounts for the irritation on this side 

 of the head, for the suppurated and even ulcerated 

 condition of the Schneiderian membrane, and for the 

 suspicious discharges. It was evident enough that 

 there was no glanders. The very circumstance of ali- 

 mentary matter being discharged through the nostril 

 was enough to prove the contrary." 



Still another case of destroying a horse for what 

 merely appeared to be glanders is recorded by Prof.
