VETERINARY DENTAL SURGERT. . 199 



On examination of the head the third molar tooth 

 proved to be carious, one-third of its fang being 

 already consumed and the remainder rotten. The 

 formation of an abscess within its socket had ren- 

 dered the tooth loose and the matter flowing there- 

 from had established a passage into the contiguous 

 chamber of the nose. The antrum, also, was in part 

 obstructed by the deposition of osseous matter. This 

 is a case which but for the inquisitiveness of Mr. 

 Cherry, would have indiscriminately merged into 

 that heterogeneous class of diseases passing under the 

 appellation of chronic glanders. 



* Surgeon William Smith, of Norwich, England, 

 reports a case of caries of the roots of several grinder 

 teeth, accompanied by a discharge from the nostril 

 which he admits he mistook for ozena. He says 

 ( Veterinarian, 1850, Pages 381-2): 



"I was requested a few days ago to visit a horse 

 which was supposed to be 'glandered'. I found the 

 animal in a most emaciated and pitiable condition, 

 with a copious, greenish, and very offensive dis- 

 charge from the left nostril with slight tumefaction 

 of the gland on the same side. There was no ap- 

 pearance of ulceration, but the Schneiderian mem- 

 brane had a leaden, dirty hue. Taking all the cir- 

 cumstances into consideration, I ordered the animal's 

 destruction, but had its head sent to my infirmary.
