ated, causing much enlargement of the jaw. He first removed the 



tooth, then divided the skin at the lower edge of the jaw, and' with 



a drill made a hole through the 



bone. Through this hole he put 



a seton to keep the parts open 



until a healthy healing process 



should be produced. A strong 



preparation of carbolic acid was 



put upon the seton, and dressed 



once a day, which finally effected 



a perfect cure. 



When the horse, without any 



apparent cause, is running down, 



munching, or eating his food but 



slowly, especially if there is any 



lateral action of the jaw, examine the mouth carefully to see whether 



there is any noticeable cause of 

 trouble in the teeth. If rough 

 and irregular, they should be 

 rasped down. The method of 

 doing this is now so well under- 

 stood as to scarcely need ex- 

 planation. 



The rasping down of all ir- 

 regularities should be carefully 

 done, and if there is a decayed 

 tooth it should be removed by 

 a veterinary surgeon who is 



conversant with the simplest and best method of doing it. There 



are regular horse-dentistry im- 

 plements in general use for 



this purpose, which can be 

 easily obtained. If the tooth 

 has grown down below the 

 level of the others, it should 

 be rasped or sawed off to the 

 proper dimensions, and care- 

 fully watched afterward so as 

 to remove any undue growth 

 harmful to the opposite parts.
