146 ALIMENTARY ORGANS. 



of these animals to gnaw upon hard substances, this 

 singular growth of their teeth would prove an un- 

 comfortable provision. 



T. There is but little danger, with their existing 

 habits and propensities, of their neglecting this pre- 

 caution ; but it is said, that, if fed only upon soft 

 substances, their teeth will grow so as to penetrate 

 the head and destroy the life of the animal. Before 

 dismissing the subject, there is another consummate 

 evidence of design, viz. the wonderful relation be- 

 tween the different parts of the mouth. 



A. The form of the teeth and the motions of the 

 jaws in all animals always correspond. The mouths 

 of the cat, wolf, dog and those animals which have 

 teeth and digestive organs suited only for flesh which 

 requires to be divided by an upward and downward 

 motion, have the jaw constructed in such a manner as 

 not to admit of any lateral or side'way action, such as 

 we notice in sheep, oxen, and the like, and which 

 would have been useless to flesh eating animals. This 

 could not be chance.— For what but design could 

 have effected such harmony of construction between 

 parts so entirely different as the stomach, the teeth, 

 and the joints by which the mouth is opened and 

 closed. The animal structure is full,— is made up of 

 such relations. So completely is it carried through ev- 

 ery part ; every part is so fitted to connected parts ; 

 and that without the least natural tendency^ that we 

 can S ee,— for what particular tendency can a jaw with- 

 out grinding teeth have to unite itself to the head by 

 a joint incapable of grinding,— this correspondency
