CHAPTER VI.
ALTHOUGH in speculating on “philosophical possibilities,” said Buffon, the same
temperature might have been expected, all other circumstances being equal, to
produce the same beings in different parts of the globe, both in the animal and
vegetable kingdoms, yet it is an undoubted fact, that when America was
discovered, its indigenous quadrupeds were all dissimilar from those previously
known in the old world. The elephant, the rhinoceros, the hippopotamus, the
cameleopard, the camel, the dromedary, the buffalo, the horse, the ass, the
lion, the tiger, the apes, the baboons, and a number of other mammalia, where

sloth.
These phenomena, although few in number relatively to the whole animate
creation, were so striking and so positive in their nature, that the French
naturalist caught sight at once of a general law in the geographical
distribution of organic beings, namely, the limitation of groups of distinct
species to regions separated from the rest of the globe by certain natural
barriers. It was, therefore, in a truly philosophical spirit that, relying on
the clearness of the evidence obtained respecting the larger quadrupeds, he
ventured to call in question the identifications announced by some contemporary
naturalists, of species of
