850 THE SIZE AND WEIGHT 



males, be the proportion of such total corresponding with 

 the weight of the Cerebellum. For females, however, the 

 relative weight of the Cerebellum is rather greater (1:8-^), 

 on account of the existence in them of a greater propor- 

 tionate diminution in the size of the Cerebrum. 



Cranial Capacities. 



The average ' cranial capacity ' for any race can only 

 be ascertained by the examination of a large series of 

 corresponding skulls, assorted according to Sex. The 

 importance of the latter point is great, because, as Flower 

 points out, difference in Sex, in its influence over capacity 

 of skull, is often decidedly greater than difference of 

 Piace. 



The methods of estimating the ' cranial capacity ' 

 have varied so much at different times, and as adopted 

 by different investigators, as to make it often both 

 difficult and unsafe to compare their results with one 

 another. 



It is most important that an international method 

 should be agreed upon, and universally adopted by workers 

 in different countries. We may then, after a time, get 

 results strictly comparable with one another.* 



Vogtf gives a table of cranial capacities by different 

 observers, the most interesting items of which have been 

 derived from the researches of Broca upon large numbers 

 of skulls obtained from certain Parisian churchyards, the 

 remains of which for different reasons had to be disturbed.
