Variation and Correlation of the Unman Skull 
It is impossible to disguise one's disappointment at the gi'eat range of results 
here exhibited. We see that the Aino are in fair agreement with the Naqada 
values, and both show uniformly greater correlation in the male. Both also are 
in fair accordance with the English measurements as far as the latter go. Even 
if we discard the last four series, no numbers being given, we are met at once 
by the remarkably low French results, where not only do both sexes show a low 
value, but they compare fairly well with results found for independent series of 
French skulls by Professor Pearson in 1896, i.e. Length and Breadth, Parisians, 
•05 + -06 and French Peasants -13 ± 07*. 
The German results also are very puzzling, even when we note that the total 
height has been replaced by the auricular height ; for the same change has been 
made without apparent influence in the case of the Aino. The German sex 
differences are so remarkable and the divergencies from other races so anomalous, 
that one is driven to question the accuracy of measurement, of record or of 
arithmetic, until one sees the names of the measuring craniologist and the cal- 
culator! Clearly much more work remains to be done here, if possible on larger 
series, and where, if it can be provided for, craniologist and calculator are one. 
Meanwhile we must confess that the Naqada, Aino and English results strike 
us as the least improbable and inconsistent of the total material. 
The craniologist who seriously examines these results must be convinced how 
little a study of one race can tell him of what is likely to occur in a second. 
Capacity, and Height, Breadth and Length. 
We have a certain amount of comparative data already available which is given 
in the table below :

the cube root of the capacity, but the coefficients ought from theoretical considerations to be sensibly 
the same as if he had correlated with the capacity itself.
