TJie Carnivora Sensation. 



Buflbn begins his seventh volume with some remarks 

 on the carnivora in general, which I would gladly quote 

 at fuller length than my space will allow. He dwells 

 on the fact that the number, as well as the fecundity of 

 the insect races is greater than that of the mammalia, 

 and even than of plants ; and he points out that " violent 

 death is almost as necessary an usage as is the law 

 that we must all, in one way or another, die." This leads
