My third and last series, that of Table XXVII., contains the estimated skull 
capacities of thirty women students of Bedford College. I arranged these students 
on a considerable pei'sonal experience of their work into three classes of ten each, 
representing clever, medium, and dull students. I then divided the skull capacity 
list into three sections—large, medium, and small capacity. I was totally unalde to 
find any correspondence between these two divisions into three classes. 
I have used in this case formulae (14) and (ft)). They give results generally in 
very good agreement, the general order not being substantially modified when we })ass 
from one series to the other. The mean found from (14) is 1390 culjic centims., and 
* The Viilues for L, B, II differ somewhat from those determined at the Dublin Anatomists’ Congress, 
but they are, I believe, correct.
