208 Pigmentation Survey of School Children in Scotland 
Tradeston, Gorbals and Hutchesontown are the only divisions of the city which 
show significant excess. Excess occurs outside the city only in one suburban group, 
that of the west, Paisley and Renfrew. 
(2) Eye Colour. The blue-eyed class, much below the average for Glasgow as 
a whole, shows significant negative differences in all the divisions and groups 
excepting the Partick and Kelvinside group, which shows a decided excess. Light 
eyes are in excess only in Anderston, the heart of the city, and in the north 
suburban area. There is a slight excess among girls in the South Govan group. 
Medium eyes are in excess in the east of Glasgow and in defect in the west. 
Starting in the north suburban area, the excess appears in St Rollox, Dennistoun 
and the Bridgeton group and finally in the Tradeston group. Govan, the south 
and west suburbs are like the general population. The defect is greater in Partick. 
The distribution of dark eyes is interesting on account of the fact that excess in 
Scotland generally is limited, when a large number of cases is considered, to one 
region of Scotland, that of Perthshire and Forfarshire. The only suburban area 
showing excess of this class is the west (Paisley and Renfrew) for girls. There is 
a slight excess in the boy population of the south suburban area. In the city, 
Partick is different from the rest of the population in that it possesses the average 
number — it is quite like the general population for this class. All the other 
divisions and groups show excess of dark eyes. It is most marked in the Tradeston 
group, the excess there being highly significant. South Govan follows and then 
Anderston and Milton. The excess is significant for boys in the Bridgeton group, 
but not quite significant among the girls of that group. 
(7) General view. The predominant colours of each of the divisions of Glasgow 
can now be stated. They are given in the following two tables. Table LI. shows 
significant positive differences only and these are classed so as to show the 
intensity of the excesses. Table LII. is a condensation of Table LI. and gives a 
brief specification of each division. 
Taking a general survey of the pigmentation distribution of Greater Glasgow 
as shown by an analysis of its divisions and the environs, one sees that the excesses 
of medium and dark hair and medium and dark eyes (found in considering Glasgow 
as a unit) are not evenly distributed over the city and suburbs. It is however the 
predominant feature of the more densely populated and larger portion of the city to 
he brown or dark in hair colour and medium or dark in eye colour. This of course 
hut confirms the general result in comparing density with pigmentation. There are 
some interesting features in the colour distribution which deserve special mention. 
The occurrence in certain parts of Glasgow of excesses of classes generally deficient 
in the city (either with or without the prevailing colours) is striking. Why, for 
instance, should Anderston have an excess of light eyes in the boy population? 
Why should Milton be the only district having even a slight excess of red hair ? 
Why should the Tradeston group be the only one in the city having an excess of 
the jet black class, and be otherwise so very divergent as it has proved to be ? 
Why should Partick be the only division in Glasgow having blue eyes in excess,.
