DISEASES OF HORSES AND CATTLE. 19 



Elongated Teeth. — Sometimes we will find one 

 or more of the molar teeth elongated, and interfer- 

 ing with mastication. In this case the elongated 

 portion requires to be cut off and the edges rasped. 

 Young horses from two to four years old suffer 

 from the development of permanent molars in their 

 sockets behind the temporary ones before they 

 drop out, causing a swelling of the jaw. If there 

 is a discharge from the nose, it will be necessary to 

 remove the temporary, and in some cases the per- 

 manent ones also. If there is no discharge, it is 

 best not to interfere, and as soon as the temporary 

 tooth drops out and the permanent one grows 

 down the swelling will disappear. Horses suffer 

 sometimes from decayed teeth. The symptoms are 

 well described by Bouley. First: Remarkable 

 fetor, which is peculiar to the disease, and per- 

 vades the mouth and the saliva within it. Second : 

 Flow of saliva from the mouth. Third: The ap- 

 pearance of a black spot on the carious tooth, or a 

 cavity varying in extent according to the duration 

 of the disease. Fouth : Sharp pain indicated when 

 the tooth is struck by any instrument. Fifth: 

 Swelling of the gums, redness and pain around the 

 diseased tooth. Sixth: The accumulation of food 

 about the diseased tooth, and which, undergoing 

 putrefaction, produces the most repulsive smell. 

 It should be removed and the £art cleaned out once 

 a day for a few days and washed with a teaspoonful 

 of carbolic acid in a pint of water.
