There are, also, some indications that these long-headed South Americans are somatically similar to the Eskimo and so, possibly, connected; but for the present, such interpretations must be taken as problems stated rather than solved. The facts are that since a general unity appears to hold for the whole New World population, we cannot expect definite chronological grouping for somatic types until the time relations of their cultural associates are determined. Our previous discussion of the time relations for culture shows that little aid can come from that quarter until new evidence is produced. Without this help, it would serve no definite purpose to summarize the few random observations of local somatic sequences found in the special literature of the subject.
