its inner corner so as to make the
obliquity still more marked. The teeth are larger than those of the
Caucasian. Finally, the Mongol is below the average of all men as regards
height, being usually about five feet four inches tall.

The original Mongolians probably developed the characteristic features we
have just noted in a Central Asiatic region, and then almost immediately
they divided into two great groups. Each of these evolved along certain
lines of its own, one sweeping northward to develop into what are now
called the Northern Mongols, the other working its way eastward and
southward to produce the peoples of China proper, Indo-China, and many
parts of Malaysia. Considering first the peoples of the Northern Mongolian
division, we find in the typical Manchurian what is perhaps the nearest
among modern people to the original race. Spreading northward and westward
from the middle Asiatic plains, this great wave has produced the nomadic
tribes of Siberia, like the Chukchi, the Buryats, and the Yukaghir. The
present inhabitants of Turkestan connect those forms which have remained
near the original home with the races of Mongolian origin that live
farther to the westward, like the Turks of Asia. But the Mongolian tide
originally swept much farther to the west, although it was driven back
later by conquering Caucasian peoples; and it has left behind such
remnants as the Finlander and the Laplander, the Bulgar, and the Magyar.
It is evident that these western branches of the Mongol stock are not at
all pure in their racial characteristics, for they clearly show the
effects of a mixture with alien European peoples. To assign them to the
Northern Mongol division means only that their dominant characteristics
are mainly those of Mongolian nature. We have referred the Russians to the
middle Caucasian division even though the Slav or Tartar infusion is very
great, but it does not dominate over the Caucasian peculiarities as it
does in the case of the peoples we have mentioned. As regards the
remaining types we must add to this brief list the Koreans and the
Japanese, the former being far purer in Mongolian nature than the latter
people, which has apparently been affected by a Malay influence from the
south.

Turning now to the southern Mongol, we find that from their cradle in the
Tibetan plateau they too have spread widely, and their descendants have
also come to differ in certain respects as they have established
