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 teet^h. If rough 

 and irregular, they should be 

 rasped down. The method of 

 doing this is now so well under- 

 stood as to scarcelyneed ex- 

 planation. 



The rasping down of all ir- 

 regularities should be carefully 

 done, and if there is a decayed 

 tooth it shoidd be removed by 

 a veterinary surgeon who is 



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



are regular horserdentistry 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 tp the 



proper dimensions, and care- 

 fully watched afterward so as 



to remove any undue growth 



harmful to the opposite parts.
