He then trephined the frontal and superior maxil- 

 tary sinuses, and much to his surprise found the 

 other half of the tooth in the frontal sinus. It was 

 removed through the opening made by the trephine, 

 the mare making a good recovery. 



*"C. D. House, Veterinary Dentist performed an 

 unusual operation on a 7-year-old horse, the property 

 of Mr. J. T. Allen of Hartford, Conn. In 1876 a 

 surgeon( ?) made an incision in the right cheek and 

 knocked out a large part of the fifth upper grinder. 

 The violence of the operation, fractured both the 

 tooth and the jaw, imbedding a large fragment of 

 the former in the bone above the socket. A year 

 afterward, the horse still suffering and discharging 

 matter from the nostril, Mr. House was requested 

 by Mr. Allen to examine, and if possible cure him. 

 He failed however to discover the cause of the dis- 

 charge, and it was not until the expiration of another 

 year that he determined to probe the case to the 

 bottom, the horse in the meantime having suffered 

 as usual. Making an instrument of the proper size 

 and shape, he introduced it into the nostril, seized the 

 tooth fragment and drew it forth, the horse at that 

 instant making a deep expiration, which blew out 

 several fragments of bone, and a part of the root of 

 the tooth. The animal made a good recovery."
