Diseases of the Digestive Organs. 221 



SUPEENUMEKAEY TEETH. 



In the case of nippers or grinding teeth these should be 

 extracted or pinched out as they are liable to injure the 

 gums, palate, cheek or tongue. 



Wolf-teeth cannDt be looked on as superfluous, being 

 natural and harmless. They are insignificant teeth situ- 

 ated directly in front of the upper, and less frequently of 

 the lower grinders. Being present during the shedding 

 and cutting of the teeth, when recurring inflammation of 

 the eyes is most frequent, they are in very bad odor with 

 people who cannot see the distinction between the mere 

 coincidence and the cause and effect. They are useless, 

 however, and may be extracted without injury, though if 

 broken they may irritate the gums. 



PAEEOT MOUTH. 



Abnormal length of the upper jaw may lead to Inordi 

 nate length of the upper front teeth which project over 

 the lower hke a parrot's bUl. If this interferes with graz- 

 ing the extra length should be removed with a saw or with 

 tooth-sJwars. But parrot-mouthed horses usually do well 

 fed in-doors. 



CEIB-BITING. 



This is a distortion rather than a disease of the teeth, 

 these being worn away on their anterior edge so as to 

 show more or less of the yellow dentine in place of the 

 clear pearly enamel. It is associated with the serious vice 

 of vnnd-sucJdng (swallowing), and eructation, which leads 

 to tympany, digestive disorder, and rapid loss of condi- 

 tion. The horse seizes the manger or other solid object 

 with his teeth, arches and shortens the neck and makes a 

 grunting noise. The wmdsiccking may, however, exist 

 without crib-biting. It may be learned by standing idle 

 near a crib-liter, and alway goes on to disease and loss of 

 condition.
