corresponds, brother and sister cannot be father and mother of the same child; but the Hawaiian system presupposes a family, in which, on the contrary, this was the rule. We are here confronted by a series of family forms that are in direct contradiction with those that were currently regarded as alone prevailing.

To-day we know that these traces, found by him, do not lead back to a stage of unlimited sexual intercourse, but to a much later form, the group marriage.
