his own observations and those of von Franque, has given in his latest paper the mean 
transverse diameter of the brim in American aboriginal women at 127 mm. and the mean 
conjugate at 115, from which an index of 90*5 can be computed, which is considerably- 
higher than the mean obtained from Verneau's measurements. The mean of the whole 
series of South American Indians, calculated from the specimens referred to in this 
paragraph, is 83"3 for the males and 91*6 for the females, so that the males are platypellic, 
the females mesatipellic. The mean dimensions of the pelvic brim in the Fuegians, 
as obtained by Garson's measurements of four male pelves of the Yahgan tribe, is trans- 
verse diameter 121 "5 mm., and conjugate diameter 98 mm. The index therefore is 
80"6, so that these islanders, like the male aborigines of the South American continent, 
are platypellic (platylekanic). 
I shall now classify in three parallel columns the people or races whose pelvic brim 
index I have analysed in the preceding pages, both from my own observations and from 
those of other anatomists. For reasons to which I have already referred, I have not 
included the female pelvis in this classification and have based it entirely on the 
measurements of the male pelvis, though, as will be seen from the frequent references 
which I have made to the brim index in the female, I consider that it assists one in 
arriving at a conclusion as to the group in which the pelvis of each race should be 
placed. ■ In those cases in which, from the few pelves which have been measured, or from 
the wide variations in the brim index, there is a doubt as to the group in which a people 
or race should be ranked I have appended a query.

How greatly the female pelvis is modified in the proportions of the pelvic brim in 
relation to the special sexual requirements is shown from the fact that in none of the
