calculated for the present series of observations on hair and eye colours, the 
values of the latter ratio being given in Tables XVIII. and XIX. The values of 
the factor ^8 = l/Vl - (m - 1) are also given in the tables, and these, 
if multiplied by the values of the relative local differences in the tables provide 
the corresponding values of {ys — ys)l'^''npq{N — m)l{N — \) for comparative 
purposes. 
Applying the foregoing test to all the hair and eye categories, it is found 
that Scotland north of the Forth is quite significantly darker than the south. 
Excepting Dundee, Fife and Argyll, which have a significant excess of medium 
hair, the country north of the Forth is significantly dark haired. The whole 
of the south-west is significantly brown haired, while a significant excess of fair 
occurs in the Stirling group ($) and in Stirling, Perth and Montrose groups (cf). 
North of the Grampians there is a significant excess of red hair among the 
females and possibly also among the males, although Aberdeen is the only group 
which shows definite significance. Turning now to eye colour we see that 
north of the Grampians there is a significant excess of medium eyes, south of
