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.
