PHILOSOPHY OF ZOOLOGY. 



do not perceive very distinct marks of the existence of 

 this instinct. It probably influences the exertions of 

 the social tribes of insects, although their condition pre- 

 cludes the possibility of observing the proofs of its ope- 

 ration.

Many of die lower animals exhibit this instinct, in their
