Physical Characteristics of the Copper Eskimos 



NASAL INDEX 



b65 



As will be seen, the tables are too irregular, the ranges of deviation far too 

 great for any importance to be attached to the resulting mean indices. Hansen, 

 who places the index in S.E. Greenland for both sexes combined at about 72, 

 remarks that there is a considerable difference between the sexes, the index 

 for women being lower than for men. In Coronation gulf there seems to be 

 hardly any difference, though both Duckworth's figures from Labrador, 64-1 

 (men) and 62-4 (women), as well as Stone's from the west, 67-7 (men) and 66 

 (women) in the Mackenzie delta, and 66-8 (men) and 63 (women) on the Noatak 

 river, seem to show it slightly. 



CONCLUSION 



From the foregoing pages we may reap the following conclusions: — ■ 



1. There is some slight support for Hansen's view that European influence 

 has produced a decrease in the stature of certain Eskimo tribes, but that its 

 effect in other ways is indeterminate. 



2. There is strong support for Boas' view that Indian admixture in Alaska 

 has increased the stature and produced a marked tendency towards brachy- 

 cephaly. 



3. The Copper Eskimos show more resemblance to the eastern Eskimos 

 than to the Alaskan. 



4. The Copper Eskimos differ from most other Eskimos in that the head 

 is slightly longer and broader, although the cephalic index is virtually the same 

 as among the pure-blood tribes to the eastward. 



5. There is no indication of European admixture among the Copper Es- 

 kimos, but a little evidence of slight Indian admixture.
