Symptoms. It may be noticed that the animal has some diffi- 

 culty in chewing his food, and frequently while eating stops and 

 throws up his head .as though suffering severe pain. While drink- 

 ing cold water he may stop and hold the head to one side, etc. 

 The above are general symptoms when the crown of the tootli 

 is decayed. When the root of the tooth alone is discard, the 

 symptoms are quite different. 'Then a swelling appears on 

 the face at the side the diseased tooth is on and directly over the 

 decayed tooth. It is the prevailing idea among horsemen that if 

 a horse has a swelling on his face they say he has "blind teeth.* 7 

 He may have blind teeth, but they seldom if ever injure a horse. 

 Blind teeth, properly known as Wolf Teeth, are little peg-like 

 teeth, situated one in front of each upper grinder, and are gen- 

 erally harmless. (See Fig. 9a, page 5(>.)
