It should be noted that we are here treating the successive social groups like individuals. Thus, if we wish to arrive at the head form for a social group, we take individuals at random and calculate from these observations the most probable average value. In exactly the same manner, we may take these values for groups in the New World and place them in a series. When we do this, we again find a typical distribution suggesting homogeneity. However, as it stands, this result should be taken only as a suggestion, for there are many complicating factors to be considered. The whole problem awaits further investigation, and so cannot be profitably considered here. That the general assumption we have made is consistent with other somatic data is obvious, for if the people of the
