The whole question of heredity, its phenomena and results, is now in process of review under the novel phases that affect anthropology; and in this view the illustrations which the New World supplies in reference to hybridity and absorption have a distinctive value. The anthropologist recognises various elements marking diversity of race in stature, colour, proportion of limbs, conformation of skull, colour and other characteristics of eye and hair. He also notes no less distinctively the diverse intellectual and moral aptitudes. Noticeable as are the diversities of national type in Europe, the range of variation is trifling when compared with the conditions under which the White, Red, and Black races have met and intermingled in the West Indies and in North and South America. The cultured and civilised races of Europe have there united their blood with the African negro and the native Indian savage; and both admixtures have been carried out on so great a scale as to furnish indisputable data for determining the question how far the half-breed is a mean between the two parents; or if there is any inevitable preponderance of one of them, with a tendency to revert to one or the other type. The intermarriage of fair and dark races of the Old World has gone on throughout the whole historic period, with apparently resultant intermediate types. The Iberians and “black Celts” of Western Europe, and the dark brunettes of the Mediterranean shores, stand out in marked contrast to the blondes of the Baltic shores. Whatever may be said of other diversities of race, Professor Huxley is led to the opinion that the Melanochroi, or dark whites, are not a distinct group, but the metis resultant from just such a mixture of his “Australioids” and his “Xanthocroi,” as has been going on for centuries on the American continent between the blondes of Europe and the native olive-skinned American, and between both of them and the dark African race.
