the Chipewyan Cree resemble the Fond-du-lac Chipewyans of Athapascan 
stock, and the Oxford House Cree resemble the Saulteaux at Island lake, 
who, like the Cree, are of Algonquian stock. This may point to the fact 
that both the Fond-du-lac Chipewyans and the Chipewyan Cree are 
more pure than the Oxford House Cree ; and that the Island Lake Saulteaux 
may, moreover, be more mixed with white blood than is supposed. If this 
be the case, then we are advised as to what physical proportions Indian 
blood dominates; and what white blood. 
Both bands of Cree have finer hair and poorer teeth than the Fond- 
du-lac Chipewyans. The blood groups of each of the thirty-three Cree 
examined belong to group 0 (Jansky, 1). These Cree, therefore, are 
universal donors. Whether this is by coincidence or not, further data will 
reveal. 
Somewhat tentatively and on meagre data the males and females of 
the three great stocks in Canada, namely, Athapascan, Algonquian, and 
Siouan are compared in tables IX and X. It would appear that the most 
noteworthy differences between the physical proportions of the men of 
these three stocks is expressed by their cephalo-facial indices, which indices, 
however, must not be considered without paying due regard to the dia- 
meters of the skull from which they are derived.
