 that to which they belong, as thick lips, a pro- 

 minent facial angle, a difference in the relative 

 proportion of certain bones to each other, the 

 curling of the hair, and the like, occur in all

 that we cannot fully appreciate. Even in ani- 

 mals, there is as much difference in general 

 characters between the Arabian steed of high 

 blood, fine form, indomitable spirit, and winged 

 speed, and the brewer's dray-horse, of a strikingly

 The long-legged swine of France, though exhi- 

 biting such a marked difference in the relative 

 length of some of their bones, are still the same 

 species with the short-legged swine of England. 

 The same argument is strengthened by the infi-
