combs on the other. But, from a study of the coefficients of variation, the 
Whitechapel English skulls are transferred to the first group. The 
Australian female for both standard deviation and coefficient of variation 
falls between the Aino, Tasmanian, and Melanesian on the one side, and 
Naquada, Bavarian, Paris Catacomb, and Whitechapel English on the other. 
We now come to the comparison of the correlation results for length, 
breadth, and height with other races (Table IV.). The comparison of the 
values for the unsexed crania of Australians with those of Tasmanians and 
Papuans has already been worked out ( 26 ). Of those remaining, only 
the values of length and breadth are strictly comparable, owing to the 
differences adopted in estimating the height measurement. The height 
measurement for Germans and Ainos is the auricular height, and not the 
total height; while that for the Naquada is in a plane from the basion 
at right angles to the Frankfort horizontal plane, and does not always 
coincide with the basilo-bregmatic height, while those marked f in the 
table are measurements on the living head. 
The values obtained for the following races are placed in order of their 
correlation, the highest being placed first, so that it can be seen at a glance 
which are more and which less highly correlated than the Australians : —

The correlation values for male skulls are those usually regarded as 
correct for comparative purposes, and from these it will be seen that the 
Australian comes about halfway in the series, and is not as homogeneous 
or, in other words, not so pure as the Eskimo, Tasmanian, Aino, or Naquada 
races. If the female crania be of any comparative value, then the 
Australian becomes still more impure, as they have the least correlation 
value of the series.
