On the vexed question of original Asiatic extraction what little evidence I have to offer is in general support of the theory that some at least of the ancestral stock probably found their way hither from Asia, or—what is more in accordance with the laws of migration as so far ascertained—spread from the American to the Asiatic continent. There is undeniably a marked prevalence of what are recognised as Mongoloid traits among these peoples. I fully accept Ratzel's dictum, “We may hold firmly to the relationship of the Americans with the East Oceanic branch of the Mongoloid race.” To quote another writer, “As Burton remarks, this strain demonstrates itself in big round Calmuck skulls, flat faces, with broad, prominent cheek-bones, oblique oriental eyes, rather brown than black. They have also dark thick eyebrows, and thin moustaches fringing large mouths, with pointed teeth and sparse beards hardly covering the long pointed chin.” The truth of this description can be judged from the illustrations in this volume. The most casual observer must notice the prevalence of Mongoloid facial characteristics prevalent among the South American Indians, such as obliquity of eye, prominent cheekbones, broad flat nose. My own observations led me to conclude that the Mongoloid type was very pronounced in individual cases, so much so that I estimated at least one per cent to be of a pure Chinese type, and my common name for them (vide my note on secrecy of individual names, p. 154) was Chin-Chin.
