The means have been taken without weighting the series. On the whole 
the results here are much more consistent than in the last table, the Germans 
being most anomalous in G and H (f, and the Aino iu C and L J'. The means 
probably give very fair average results, which will serve for general racial com- 
parison. They show on the whole no very marked sexual preponderance in corre- 
lation, although such undoubtedly exists in individual races, e.g. German female 
is sensibly more, Aino female is sensibly less, correlated than the male. There 
is small doubt that these capacity correlations come out better than those between 
the lengths chiefly because they are higher, and accordingly the probable errors 
of random sampling less. Possibly the best method of dealing for the present with 
the latter will be to investigate them for long series of measurements on the 
living, replacing the total height of the skull by the auricular height of the head. 
Capacity and Circumferences. 
We have at present very limited data for these cases, only indeed the Thebans 
and Naqadas :

Considering the close relationship of Naqadas and Thebans these results are 
singularly different, but we must remember that it is precisely in length and 
breadth that differentiation has been shown to have taken place, and these would 
directly affect the correlationship of circumferences. 
The historic Egyptians show in every case higher correlation than the Naqadas, 
and in both series with one exception the males are more highly correlated than 
the females. The divergence between the sets of values for two so closely allied 
series indicates how difficult it would be to reconstruct satisfactorily skull-capacity 
from any general formula connecting capacity and the circumferences. 
* These results are for a rather more extensive series of skulls than those dealt with by Dr A. Lee :
