196 PBACTURED JAWS. 



ing this delay my attention was attracted to the shaft 

 horse, which had an enormous tumor on the right side 

 of its face. It had such a singular appearance that I 

 dismounted from the carriage and induced the driver 

 of the wagon to halt, when I inquired into the history 

 of the case, and made an inspection of the tumor. It 

 was as large as half a good-sized cocoanut, occupied 

 nearly the whole side of the face, and was literally 

 a mass of what at first appeared to be fragments of 

 bone, but which, on a closer examination, proved to 

 be imperfectly developed grinder teeth. The tumor 

 looked as if it were composed entirely of them. I was 

 informed that, when two years old, the foal had taken 

 fright and ran away, and in trying to get through a 

 gate, a wooden stump ran into its face, making a large 

 hole. The hole filled up, the tumor gradually formed 

 on it, and since that time these 'bits of bone,' as the 

 wagoner called them, were constantly shed from its 

 surface. The growth was so large that the collar was 

 passed over the head with great difficulty. I was so 

 much interested in the case that I offered to keep the 

 animal while the removal of the tumor was attempted; 

 but the farmer could not spare it from work at the 

 time, and I did not have another opportunity." 



The following accounts of cases of fractured jaws 

 treated by various surgeons are from Prof. Youatt's 

 work, " The Horse" (p. 445) : 



" Surgeon Cartwright had a mare in which the up- 

 per jawbone was fractured by a kick at the point 

 where it unites with the lachrymal and malar bones. 

 He applied the trephine, and removed many small 

 bones. The wound was then covered by adhesive 

 plaster, and in a month the parts were healed.
