 DENTAL NEURALGIA. 



BY MR. MACORPS^ 



*"An old horse had for about a week refused food, 

 carrying his head down and resting the occiput up- 

 ward against the lower border of the manger, as if 

 trying to raise it. The patient was dull and listless, 

 the mucuous membranes pale, the coat staring, the 

 flanks retracted. At times the muscles of the neck 

 were the seat of slight trembling, and he had convul- 

 sive movements, as if in great pain. Careful inquiry 

 into the history of the trouble failing to throw any 

 light upon the case or aid in the diagnosis, a minute 

 examination of the mouth was made when a black 

 foreign body was found projecting between the first 

 two molar teeth of the lower jaw. This was knocked 

 off with a chisel and hammer, and followed within 

 an hour by complete recovery." 



FRACTURES OF TEETH. 



Fractures of the teeth sometimes occur and 

 become a source of great annoyance to the animal. 

 The fracture may arise from various causes and 

 assume various forms. The tooth may be fractured 

 longitudinally, through the center, or transversely 

 through the crown, neck or fang. Sometimes the 

 crusta-petrosa or external layer of enamel becomes 

 separated from the main portion of the tooth. This 

 latter condition I have frequently found present in 

 colts from one to two years of age. Fig. 27 and
