E.
PENINSULAR MONGOLIDÆ.
This division comprises tribes which, I believe, have not hitherto been thrown in the same class, tribes separated from each other by considerable breaks in the geographical, and even in the ethnological continuity. Some of these lie within the Arctic Circle; others as far south as 26° north latitude. Not less distant are the two extremes of their social development; one section of the group partaking of the civilization of China, another exhibiting the rudeness of the Samöeid, and Yeniseian.
PENINSULAR NATIONS AND TRIBES.
Physical conformation.—Mongol.
Languages.—Agglutinate. In some cases excessively poly-syllabic.
Area.—Islands and peninsulas of the north-eastern coast of Asia.
Divisions.—1. The Koreans. 2. The Japanese. 3. The Aino. 4. The Koriaks. 5. The Kamskadales.
After indicating the points of difference, it is necessary to justify the present classification by showing in what way the divisions of the Peninsular Mongolidæ agree.
1. They agree in their land and water relations—being, as is expressed by the epithet applied to them, the inhabitants of either peninsulas or of islands that form an extension of them; a fact wherein we have, to a certain extent, common conditions in the way of physical, and common conditions in the way of social development.
2. They lie within a few degrees of the same longitude. This, however, is a mere consequence of their position on the same side of the same continent.
