DATA FOE THE PROBLEM OF EVOLUTION IN MAN.

(h.) There is greater equality of variation for the two sexes in uncivilised than in 
civilised races. 
(c.) Man tends with advance in civilisation to gain in size on woman. 
(cl.) Woman tends with advance in civilisation to gain in variability on man. 
(6.) Turning to the correlations we obtain for Aino and Germans the results given 
in Table II. The correlation-coefficients are clearly very different for the two races. 
Putting aside the somewhat erratic correlation of capacity and cephalic index, we note 
that for the Aino the female correlations are all less than the male, but for the

German the female are all greater than the male. Further, with the same omission 
in live out of the six cases, the Aino male is more highly correlated than the German 
male, and in four out of the six cases the German female is more highly correlated 
than the Aino female. This is again in general agreement with the results suggested 
in the second paper cited above, namely :—^ 
(«.) That correlation is more nearly equal for the two sexes in uncivilised than in 
civilised races, and 
(6.) That woman tends with advance to gain in correlation on man. 
* This confirmation of the results of the above paper is of interest, since they have been called in 
cpiestion by E. T. Bkewster (‘Proc. Boston Soc., Nat. Hist.’ vol. 29; pp. 1.5 61). His series, however, 
are extremely small and his treatment of them not entirely satisfactory.
