For purposes of easy reference, we have calculated the differences and 
the Diff./P.E. diff. for Sullivan’s 1 data on pure Sioux and Sioux-white 
breeds, and have placed the figures side by side with the pure Chipewyan 
and Chipewyan-white breeds in table VII. 
From this it will be seen that the measurements of the Chipewyan and 
Sioux breeds tend always to depart from the measurements of the pure 
Chipewyan and pure Sioux in a common direction. Further, the breeds 
are seen to have narrower ears and larger hands, for their hands are both 
longer and broader than those of the pure. 
The differences between the Chipewyans at Fond-du-lac and the 
forty-four who are “assumed to be pure”; and also between the Fitzgerald 
Chipewyans and the Chipewyan-white breeds, were worked out, and the 
few differences found between them are noted below. Now, when it is 
recalled that of the forty-four who are “assumed to be pure” Chipewyans, 
eighteen are drawn from the group of thirty-three Fond-du-lac men, and

(New York, 1920).
