The table (Table XXIX.) shows that in the girl population of the entire 
north, excess of blue eyes and fair, dark and black hair occurs together. Excess 
of blue eyes, although common to the entire north for the boy population, is 
associated with great excess of fair hair only in the North-Western division, and 
with excess of red hair in the North-Eastern division, which excess is also

characteristic of the girl population in that division. The characteristic feature 
of the East-Midland division is that it posse.sses both an excess of blue eyes and 
an excess of dark eyes. There is an excess of fair hair ($), and a defect of red 
hair ((/), but otherwise the hair distribution does not markedly differ from the 
general population. The West-Midland population differs quite sensibly from 
the East-Midland. The characteristic feature of the West-Midland population is 
that excess of light eyes occurs with excess of both dark and jet black hair. The 
South- Western division with its dense urban populations is quite different from 
the Southern and South-Eastern divisions. The South-Western population has an 
excess of medium hair occurring with excesses of medium and dark eyes, while 
the remaining Southern population is characterised by an excess of fair hair 
only. The Southern division ( $ ) has the excess of fair hair occurring with 
excess of light eyes. 
The question may well be asked ; What can one learn from all this maze of 
detail as to the significant differences in the distributions of the various colour 
classes ? Are they racial differences or differences due to other factors ? One 
* III some cases the excess positive frequencies are not quite significant (see tables of relative 
differences, Table VII.).
