influence of climate upon the colour of the hair, both of men and of animals,
that, in the kingdoms of the north, black hair is seldom seen; and hares, squirrels, weasels, and
many other animals, which, in countries less cold, are brown or grey, are there white, or nearly
so. The differences produced by cold and heat, is so conspicuous, that in Sweden hares, and
certain other animals, are grey during the summer, and white in winter.
But there is another circumstance more powerful, and, from the first view of it, indeed
insuperable; namely, that in the New World there is not one true black to be seen, the natives being
red, tawny, or copper-coloured. If blackness was the effect of heat the natives of the Antilles,
Mexico, Santa-Fé, Guiana, the country of the Amazons, and Peru, would necessarily be so, since
those countries of America are situated in the same latitude with Senegal, Guinea, and Angola, in
Africa. In Brazil, Paraguay, and Chili, did the colour of men depend upon the climate, or the
distance from the pole, we might expect to find men similar to the Caffres and Hottentots. But
before we enter into a discussion of this subject, it is necessary that we should examine the
different
