DE. A. LEE AND PEOFESSOE K. PEAESON ON 
In the Aiiio I'ace the length is more highly correlated, with the capacity than the 
other dimensions are. In the German race, on the other hand, it is the breadth. Thus 
Ave shall find for the Ainos that formnlse involving the length, and for the Germans 
that formnla3 involving the breadth, give the least probable error in the reconstruc¬ 
tion of the cajAacity. It AAmiild be of interest to investigate whether this result is a 
distinguishing mark of dolichocephalic and ijrachycephalic races. 
The correlation of capacity and cephalic index is, as I have said, somewhat erratic. 
For the Aino male and female it is quite sensible but negative. In other words, in a 
dolichocephalic race, it Avould appear as if dolichocephaly tended toAA’ards greater 
skull capacity. On the other hand, among the brachycephalic Germans, there is for 
the males a sensible correlation of a positive kind between capacity and brachy- 
cephaly. For the German Avonien, however, we find this correlation less than half 
the probable error, and thus practically non-existent. 
In order to throw, if possible, more light on this point the results in Table III. 
were Avorked out for tAvo races, one of AAdrich is rather more dolichocephahc than the 
Aino. Ill this case very little stress can be laid on the ? modern Egyptians ; they 
are far too fe-Av in number. The ? Theban mummies gi\’e a sensibly zero correlation, 
but in the three other cases the correlation is clearly negative. Thus there appears 
to lie little doubt that in dolichocephalic races those Avho ])ossess the race character 
most markedly have the greater skull capacity.
