(8) Dark Hair. (Maps IX., X., XXVII. and XXVIII.) The distribution of 
dark hair is very striking. Significant excess is found in the entire west of 
Scotland, and compared with the general population there is a corresponding 
significant defect of this class in the east. The Northern, North- Western and 
West-Midland divisions {^) and the North- Western, West- Midland and South- 
western divisions ( $ ) are distinctly megalometropic. The South- Western division 
for boys shows slight excess. Examining the counties, it is seen that Sutherland, 
Ross and Cromarty, Inverness, Argyll and Kirkcudbright, all in the west, are for 
boys megalometropic. Kincardine (cj") is the sole eastern megalometropic county. 
Significant excess among the girl population occurs only in the counties of Ross 
and Cromarty, Inverness, Argyll, Renfrew and Wigtown. There is only a slight 
excess in Kirkcudbright. Examining the districts it is seen that Mull, Jura and 
the portion of the mainland opposite is the most significantly dark population 
of Scotland. Then follow the remaining portion of Argyll, the western portions 
of Inverness, Ross and Cromarty {excluding Skye) and Sutherland. Although Ayr- 
shire (cf ) is not megalometropic, the southern portion below Ayr itself is, the 
district analysis showing significant excess in the Doon region and also in the 
southern portion of Galloway (Wigtown and South Kirkcudbright). The district
