Divisions.—1. The Samöeids, 2. The Yeniseians. 3. The Yukahiri.
The discontinuity of the Hyperborean area is to the following extent:—
a. The Samöeid class falls into two divisions, a northern and a southern; and these are separated from one another by Turk, Yeniseian, and Ugrian tribes.
b. The Yeniseians are surrounded by Ugrians, Turks, and Tungusians, with which they have less affinity than with the Samöeids, from whom they are separated.
c. The most western Yukahiri are separated from the most eastern Samöeids by Yakut Turks and Tungusians.
This discontinuity of area must be taken along with two other facts.
a. That the Hyperborean nations are nations of a receding frontier.
b. That the Turks, Tungús, and (in relation to the Hyperborean), the Ugrians, are nations of an encroaching frontier. These give, as an inference, the probability of the three separate divisions having once been continuous; so that the original Hyperborean populations must be considered to have been broken up, and partially superseded by the Turks and Tungusians, and to exist, at present, only in the form of fragments.
