 stream has swept the members of the cat family in 

 different directions, but a stealthy undercurrent has 

 seized them from beneath, and they are now happily 

 reunited. 



Animals of the Old and New World Changed 

 Geographical Distribution. 



Writing upon the animals of the old world,* and 

 referring to the humps of the camel and the bison, 

 Buffon shows that very considerable modification may be 

 effected in some animals within even a few generations, 

 but he attributes the effect produced to the direct in- 

 fluence of climate. Buffon concludes his sketch of the
