is due to imperfect mastication of the food. A very 

 offensive and disagreeable odor is also emitted from 

 the mouth, especially if the carious condition is far 

 advanced. 



Young animals affected with carious teeth yield 

 more readily to its effects and sooner become emaci- 

 ated than older animals similarly affected. 



Figure 21 represents caries of the 

 right lower corner incisor of a gray 

 mare six years old. The correspond- 

 ing temporary tooth was not shed in 

 the natural manner. It remained in 

 position until the mare was past five 



years of age, and was then removed

 moval of the temporary tooth, the gums about the 

 wound began to tumefy, and became very tender to 

 the touch, so much so that it materially interfered 

 with mastication. As a result the animal fell away 

 in flesh and presented a rather dejected appearance. 

 About six months after the first operation the gums 

 were lanced and the tooth illustrated extracted, 

 affording marked relief, the gums in a short time 

 assuming a natural condition. This tooth being a 

 permanent one has never been replaced by an- 

 other.
