Dumbarton, Renfrew and Linlithgow, all contiguous — that is, practically the whole 
of the Scottish Midlands ; Berwick, Peebles and Selkirk, contiguous in the south- 
east, and finally Kirkcudbright and Wigtown in the south. 
The girl population shows on the whole equal divergencies in the northern 
counties already mentioned, divergencies which are due to excess of blue eyes ; in 
Ayr the divergency is almost entirely due to blue eyes and scarcely any to light 
eyes as among the boy population. The divergency in Lanark is only just 
significant and is due to excess of both medium and light eyes. Wigtown and 
Kirkcudbright arc both significantly divergent, due in the case of Wigtown to 
excess of blue eyes and in the case of Kirkcudbright to excess of light eyes. 
Galloway therefore differs distinctly in its boy and girl distributions of eye colour. 
The non-divergent regions or rather the non-significantly divergent regions in the 
girl population for eye colour are as follows : Caithness and Banff in the north ; 
Perth, Linlithgow, Stirling, North Lanark and Renfrew all contiguous ; and Ber- 
wick, Selkirk and Peebles also contiguous near the Border. 
(7) Districts. Looking at the district results, they confirm the county analysis 
and also the conclusions arrived at with respect to hair colour. The populous 
Midlands, namely. North Lanark, Perth, Stirling, Dumbarton, Fife and portions of the 
east coast (i.e. Forfar and north-east Aberdeenshire, and from Nairn to Caithness) 
are all comparatively representative of the general population in eye colour. Thus 
while Glasgow itself is divergent, the great part of the environs is not. Such 
populous centres as Greenock, Kilmarnock, Falkirk, Ayr, are scarcely significantly 
divergent. Edinburgh, Dundee and Aberdeen cities are significantly divergent. 
In Aberdeen it is due to excess of medium, in Dundee to excess of dark and 
medium and in Edinburgh to excess of dark alone. It is seen, just as in hair 
colour, that the very sparsely populated regions and the very thickly populated 
areas are the most divergent. But while all the sparsely populated regions diverge 
on account of excess of blue eyes, all the very densely populated areas diverge 
because of excess of light, medium or dark. It is to be expected that Dundee 
would have a fair proportion, or even excess, of dark eyes, since the country 
adjacent to the city, namely, Perthshire and Forfarshire, are the only counties in 
Scotland showing excess of this class. The reason for the excess in Edinburgh is 
not so apparent, unless the migration from these counties to the capital is greater 
than from the rest of the country. The foreign population, as will be shown later, 
is significantly associated in general with dark eyes, but on examining the returns, 
it has been found that foreigners are not present in Edinburgh in sufficient 
numbers to affect the distribution of dark eyes in the school population there. 
With Glasgow or certain districts of the western city, the case is different, as will 
presently be shown. Forfarshire and Perthshire people are perhaps likely to have 
migrated to Edinburgh in greater numbers than people from other parts. This 
would account for the excess. The excess of medium eyes in Glasgow may be 
partly accounted for by a greater proportion of migrants from Lanarkshire, Dum- 
fries, Peebles, Selkirk and Fife, all counties with a distinct excess of this class.
