12 THE CRANIOMETRY OF SOUTHERN NEW ENGLAND INDIANS. 



TOTAL FACIAL INDEX. 



The total facial index could be obtained in only a very few specimens because the mandi- 

 ble was either entirely missing or badly broken. The average index of lO females, Table 

 VII, is 87.84; of 17 males, 84.33.

The females show a tendency to be more mesoprosopic, while the males are more 

 chamaeprosopic. This is in accord with the conclusions obtained from a study of the 

 superior facial indices. 



A possible correlation between the shape of the head and that of the face, which suggests 

 itself in this connection, is shown by combining the Length-Breadth and Superior Facial 

 Indices, and calculating the percentage of each combination (Table VIII). From this it 

 will be seen that 29.5% of the Dolichocephalic skulls, and 12.2% of the Mesocephalic skulls 

 are Mesoprosopic. 10.2% of the Mesocephalic skulls are Leptoprosopic. These results do 

 not bear out the idea of correlation.

NASAL INDEX. 



The nasal height, taken from nasion to naso-spinale, varies from 39-57 mm., with an 

 average of 50.33 mm. The breadth varies from 21-31 mm., with 25.77 mm. as the average. 

 The mode of the frequency curve of the nasal indices is at 50.0, figure 8, showing that 

 the larger number of indices fall in the classes Mesorrhine and Chamaerrhine. See Table 

 IX.
