relation, though this differs in the two sexes/ to the size of the brain. 

 Throughout the habitat of the Eskimo the module shows good propor- 

 tions and a considerable similarity. There are some differences, but 

 these would probably duninish were all the localities represented 

 adequately. The female-male relation of the module, in the larger 

 groups, is also much alike. The details are given in the next table.

CRANIAL CAPACITY 



The cranial capacity was taken by the method described in my 

 Anthropometry,^ Though I am convinced that this is the best 

 method devised so far, it is still laborious, time-consuming, and not 

 ideally satisfactor3^ It would almost seem desirable to replace the 

 measurement by that of the mean diameter, were it not for the fact 

 that it is a great and often a deciding factor in the sexing of the 

 skull. This is due to the fact that the relation of the capacity to 

 the module is in general markedly less in the female than in the male 

 cranium. There are exceptions, but they are mfrequent. In the 

 males the capacity in cubic centimeters is near the module expressed
