to his perceptibly thicker cranium. However, these results are of 

 importance to anthropology, and possibly also to educators, showing 

 that there is none or but little inherent defect in quantity of the brain 

 tissue in these Indians.

Form of the Head 

 Cephalic Index. — The two series of Chippewa reported in 1896 by 

 Boas 1 gave for the more easterly contingents of the tribe, in males, 

 the cephalic index of 82.2, and for the more westerly 80.2. These 

 results alone are sufficient proof that the series in question included 

 many mixed-bloods, who, being mostly of French-Indian origin, pos- 

 sess relatively shorter and broader heads. The series examined by 

 the writer gives the averages of 79.6 for the males and 80. 1 for the 

 females, which would correspond to about 77.6 and 78.1, respectively, 

 in skulls, proportions which are probably much nearer the true type 

 of the head in this tribe than those above. By the usual classification 

 and considering the skull rather than the head, about nine-tenths of 

 the full-blood-like Chippewa are dolichocephalic to mesocephalic, and 

 approximately one-tenth mildly brachycephalic.
