In each of the foregoing the collateral lines are finally brought into and merged in the lineal line, which is a fundamental characteristic of the system. This also gives the tenth indicative feature. Certain relationships are here called "indicative," because they determine those which precede and follow them; and because they embrace so much which is radical and fundamental, that, when they are found present in different systems of relationship, the identity of these systems may be considered established.

The Seneca-Iroquois system of consanguinity and affinity, as given in the Table, now prevails, with modifications, in upwards of seventy Indian nations. Its radical characteristics are found in their several systems with such striking exactness as apparently to leave no doubt that it was derived into each stock-language with the blood from a common original source.

Another fact, not less significant, remains to be mentioned, namely, that the system of relationship of the people of South-India speaking the Dravidian language, and numbering upwards of twenty-eight millions, is identical, with the exception of two or three unimportant particulars, with the Seneca-Iroquois. The same system, greatly modified by Sanskritic influence, also prevails among the people of NorthIndia speaking the Gaura language, and numbering upwards of one hundred millions; and also, with further modifications, among the Chinese and Japanese.

For the purpose of comparison, and also for reference to the Asiatic form in the solution of the origin of the classificatory system, the Seneca-Iroqouis and the Tamil systems are placed side by side in the following Table.
