proportion remains about the same as in NE. Greenland and Hudson Bay. 

 The great size of the head in Coronation gulf comes out in the figures for the 

 horizontal circumference, which average 581 mm. for men and 571 mm. for 

 women, as against 559-5 mm. for men in Labrador and 547-2 mm. for women, i 

 Hansen, unfortunately, has not separated his data from NE. and SE. 

 Greenland so that graphs can be constructed for each region, but from his table 

 of the range of indices in both places and for both sexes combined I have plotted 

 a graph to place alongside that given by the Copper Eskimo figures. The 

 two polygons are evidently very much alike, but the Coronation gulf group has 

 not the tendency towards dolichocephaly that is displayed by the East Green- 

 land group, a tendency that, to judge from the means quoted above, is more 

 marked in the SE. than in the NE. Greenlanders.

 East Greenland. The broken line represents East Greenland. 



These graphs again raise the question as to whether there is not a slight 

 admixture of Indian blood among the Copper Eskimos, making the head more 

 pronouncedly mesaticephalic as well as increasing the stature.^ On the whole 

 I am inclined to favour this assumption, especially in view of the fact that a 

 few individuals (see Section I, Males 12, 18, 37 and 57) seemed to resemble 

 Indians in cast of feature. This admixture must have been very slight however 

 since it has failed to produce any wide departure from the pure Eskimo type 

 as found to the eastward; and altogether the evidence is so scanty that I hesitate 

 to lay any stress upon it.
