differ from each other in length of lower limb, hence the difference in their 
stature and sitting height index. In breadth of forehead, in chin to hair- 
line diameter, in length of upper lip, and in the proportions of the ear they 
do not significantly differ from each other; but in width of mouth and 
in length and breadth of hand there are certainly differences between the 
two tribes. The Chipewyan men have the larger mouths; the Beaver 
men have the smaller hands. 
As regards the adult females, aged twenty to fifty-nine years, they are 
dealt with in the same manner in Table XIV. Jenness measured thirty- 
one Sekani and Carrier women, and the author measured eleven Beaver. 
It is evident that the number of Beaver women is too small to deserve 
much attention. For example, their mean cephalic index is slightly 
lower than that of the males, which is too contrary to precedent to allow 
of its being accepted unchallenged on the slender evidence of eleven 
individuals. 
When the Sekani and Carrier women are compared with the Chipewyan 
women (section E) it will be seen from the fourth column that they differ 
from each other in much the same respects as do the men of these two 
tribes, that is, in stature the Chipewyan women are the shorter (Diff. /P.E. 
diff. 8-9), they have a lower cephalic index, and perhaps a shorter and 
narrower head; there is no significant difference in the width of the face 
nor is there in the proportions of the nose; a reference, however, to the 
tables conveys much more than can words. 
SUMMARY 
This report deals with the descriptive characters, measurements, 
and blood groupings of certain tribes of pure Canadian Indians of Den6 
or Northern Athapascan stock. These tribes are the Beaver Indians of 
Peace river; and the Sekani, and Eastern and Western Carrier Indians 
of Fraser river. The number of adults examined were sixty-four males 
and forty-two females, in all one hundred and six adult persons. In addition 
to these a number of old people and children were measured. When to 
these are added the adult Chipewyan Indians examined in 1928 the number 
of pure, or assumedly pure, D6n6 Indians is brought up to one hundred 
and seventy-one, of whom one hundred and eight are men, and sixty- 
three women. 
Of descriptive characters the hair, nose, eye, lips, teeth, digital 
formula, and blood groups are remarked on: of the sixteen measurements 
taken twelve are related to the head; the remaining four are stature, 
sitting height, and length and breadth of hand. The intertribal differ- 
ences between these Indians are for the most part not great. Notable are 
the high percentage of eyes of lighter shades among the Carrier and Sekani 
Indians ; and the high percentage of group A blood among the Beaver Indians. 
These people are short in stature, broad headed, with very high 
cephalo-facial index, ranging by tribes from 96-2 to 98-4 for the men 
and from 95 ■ 5 to 96 • 4 for the women. These and the other facts related to 
their measurements are set out clearly in Tables XIII and XIV. For 
purposes of comparison the measurements of the thirty-six Chilcotin 
men and twenty-two Chilcotin women, a tribe allied to the Carrier Indians 
measured by Boas and Farrand in 1897, are considered. They are seen
