The Mongolian or 7th sub-race seems to be the only one that had absolutely no touch with the mother-continent. Having its origin on the plains of Tartary (marked No. 7 on the second map) at about latitude 63º North and longitude 140º East, it was directly developed from descendants of the Turanian race, which it gradually supplanted over the greater part of Asia. This sub-race multiplied exceedingly, and even at the present day a majority of the earth's inhabitants technically belong to it, though many of its divisions are so deeply coloured with the blood of earlier races as to be scarcely distinguishable from them.
