 though we flatter the self-love of men and nations by the legend of pure races, all our experience is of the gradation and resolution of races, and strange resemblances meet us every where, It need not puzzle us that Malay and Papuan, Celt and Roman, Saxon and Tartar should mix, when we see the rudiments of tiger and baboon in our human form, and know that the barriers of races are not so firm, but that some spray sprinkles us from the antidiluvian seas.
