Eskimo Skulls: Basion-Nasion Length and Its Relation to Length op 



Skull — Continued 



SEXES SEPARATELY IN ASCENDING ORDER 



An interesting point is that in the north and northeast, where the 

 skulls are longest, there is evidently a slightly greater relative de- 

 velopment 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.
