THE CRANIOMETRY OF SOUTHERN NEW ENGLAND INDIANS. 



females and 65.38% of the males have the frontal. larger than the parietal. Schwalbe and 

 Drontschilow are both of the opinion that the Brachycephalic forms show more Simian 

 characteristics in this relation than the Dolichocephalic. While there are very few Brachy- 

 cephalic forms among the Indians studied, it is true that the Dolichocephalic heads are less 

 apelike in the fronto-parietal relation than the Mesocephalic. See figure 12. 



The amount of bulge in these bones is shown by the relation of the arc to its chord ; the 

 higher the index, the more nearly do the two approach ecjuality, and the less the bulge. 

 Figure 13 shows that in the Indian the most frequent frontal index is 88; the parietal, 89; 

 the occipital, 83. The occipital has by far the greatest protuberance of the three bones, 

 for many of the indices run below 80. The occipital bone of the New England Indian is 

 considerably more bulging on the whole than that of the other races with which it is 

 compared in the curves in figure 14, the Old Egyptian, Kamerun, Telei and Czech. From 

 Table XVI, we find that 15 of the 47 males, or 31.9%, and 6 of the 25 females, or 

 24 9^, have the occipital arc larger than the parietal ; while Frizzi found 9 out of 44. or 

 20.45%, "'' li^s Telei. In only 8 cases out of 72 is the frontal arc less than the occipital; 

 in all the remaining cases, it is greater.
