REPORT ON THE HUMAN CRANIA. 
75 
the ascending ramus was high. In the other, a female, the bone was not so strong, and

The mean cephalic index of the eight adults was 75 '2 ; the range of variation from the 
maximum 80 (male), to the minimum 72 (male), was 8. The crania were therefore, on the 
average, just within the mesaticephalic group, although three of the skulls were below 75. 
The mean vertical index was 73, and the range of variation from the minimum 70 (male)
