An interesting point is that in the north and northeast, where the
skulls are longest, there is evidently a slightly greater relative
development of the occipital portion of the vault, or slightly lesser
development of the frontal portion.
Some additional points of interest appear when the basion-nasion:
skull-length index, taken collectively for the two sexes, is compared
in the different groups. All these comparisons suffer, naturally,
from unevenness and often insufficiency of the numbers of specimens,
yet some of the results are very harmonious with those brought out
repeatedly by other data. Thus the St. Lawrence material stands once
more close to the medium of the southwestern and midwestern groups;
Barrow and Point Barrow are almost identical; and so are the Old Igloos
from near Barrow and Greenland. The St. Michael islanders show very
favorably in the midwest, the Shishmarefs in the northwest and the
Southampton islanders in the northeast.
