Analysing the above table, we find that, comparing the percentages in the male 

 and female groups, those in the platyrhine group are equal, while there is about 

 8 per cent, less in the female leptorhine group than in the corresponding male group. 

 Combining the female and male groups, we get figures comparable with those 

 supplied by Turner, and we observe that there is 9 "3 per cent, less in the lepto- 

 rhine group in the present collection than in Turner's series, and of this 6 "3 per 

 cent, is found in the mesorhine group and 3 per cent, in the platyrhine group. 



With regard to the orbital index, we have for the female the same three group- 

 ings as for the male : —

Comparing the male with the female groups, we find that, while the percentages 

 in the mesosemic groups are approximately equal, about 15 per cent, less are found 

 in the female microsemic group than in the corresponding male group, which is com- 

 pensated for by an excess of 15 per cent, in the female megasemic group over the 

 corresponding male group. Comparing the present series, taking male and female 

 together, with Turner's series, where male and female results are aggregated, we 

 find 3 per cent, less in Turner's microsemic group ; 10 per cent, less in his mesosemic 

 group than in the corresponding groups of our series, while 13 per cent, is added to 

 the megasemic group. The tendency for the orbit to be relatively high compared 

 with its breadth is thus better marked in Turner's series than in the present one. 



As regards the maxillo-facial index we can analyse the following table : —

Even more markedly than Turner's series does the present series, including male
