236 Variation and Correlation of the Human Skull 
The correlation in the English is remarkably close to that in the Thebans, 
and considerably greater than that in the Naqadas. In the pair G and JJ, the 
female is the more highly correlated, in the pair G and Q the male has the 
advantage in all three series, but there is no marked preponderance in favour of 
either sex except in Theban G and Q. Unfortunately there is as yet no published 
material available for further comparison. In the English, the female is con- 
siderably the more highly correlated in G and S, but in the pair G and the product 
JJSQ the correlation of the sexes is practically equal. 
Gorrelation of Gircumferences. 
The only material available for comparison is Naqada and Theban Q and U, 
which are included in Table XV.

We again notice that English and Thebans are very much alike, this time in 
regard to the correlation of U and Q, both having a considerably higher correlation 
than the Naqadas; in all three series, the female has the higher correlation for 
this pair of characters. In English, for the pair S and U, the female correlation 
preponderates ; for S and Q, the male, just as we found in the pairs G and U and 
G and Q. 
Orbital, Facial and Palatal Measurements. 
Only the Naqada results are available for comparison. In our series the 
marked difference between the sexes in the correlation of height and breadth 
of orbit will be noted : in the left orbit, the correlation is more than three times 
as great, in the right orbit about twice as great, in the males as in the females. 
The nose, palate and face correlations are small in both sexes, and their probable 
errors are comparatively large. 
In these respects the English differ very markedly from the Naqadas. In the 
latter, the correlation of height and breadth of orbit is much the same for both 
eyes and for both sexes, and the palatal and facial correlations are considerable in
