Again there is practically little to be learnt, the Gorillas are very variable in 
nasal chord and much less variable (in scale position) on the subtense, while the 
reverse holds for the Chimpanzees, the subtense being far more variable than the 
chord. The Negroes are as a rule low down on the scale, being considerably more 
variable than the English, Egyptians or Hindoos. In 9 cases the female and in 9 
the male is more variable in simotic characters. 
Lastly we pass to the indices, omitting the calculated mesodacryal subtense 
index a. We find for Standard Deviations the order given in Table XVII. 
Again there seems little to be learnt with regard to racial variability from 
these results, beyond the confirmation of what we have learnt from the earlier 
tables that the Orangs, and the Gorillas as a rule, have large variability ; here, 
however, — as distinguished from the coefficients of variation of the absolute 
lengths — the Chimpanzee is seen to have very small variability. If, however, 
we take the coefficients of variation of the indices we find the Chimpanzee is 
associated with the other two anthropoids of our scales in high variability. 
Turning to the sexual differences, we find in the apes as many cases (4) of female 
as of male greater variability; among the human races there are 10 cases in which 
the female is more variable and 11 cases in which the male is more variable, or 
again there is little if any distinction of sex in variability. 
An examination of Tables XIII and XIV will show the reader that much of 
the non-significance of the variation scale for racial purposes is quite possibly due
