be determined. What the writer wishes to lead up to is this. In Scotland the 
distribution of colour is roughly, 1 fair, 2 mixed, and 1 dark. Is it fair to infer 
that the original elements of the Scottish population were fair-haired and dark- 
haired races in approximately equal proportions ? Proof is wanting but the 
distribution is suggestive. From our knowledge of the distribution of eye colour 
in Scotland, it is unlikely that although there were fair-haired and dark-haired 
races, the two elements were entirely blonde and brunette — the blue-eyed fair- 
haired type, and the dark-eyed dark-haired type. It cannot be sliown from the 
data what proportion of the dark-haired element was of the brunette type or 
what proportion was of the type found in the Gaelic speaking population, the blue 
or light-eyed dark-haired Keltic type. Who were our ancestors of the brunette 
type? Were they of the Mediterranean or Danish type or both? The fair- haired 
element probably was made up of the blonde type, Scandinavians and others of 
Germanic stock who, history tells us, came to our shores in bygone centuries and 
who fought, struggled, settled and made Scotland — the Scotland of the dark-haired 
Kelt — their home. Together with the darker elements they may have united and 
appear to be now uniting to form a blend — the Scottish type — one which in 
physical characters has proved itself vigorous and which, considering mental 
characters, has been at least relatively as productive of men of ability as any in 
the British Isles. 
III. Tlie Data hearing on correlation, and comparison with similar data, 
(a) General. Hitherto, throughout the entire course of this investigation, the 
author has been considering hair colour and eye colour separately — taken one at 
a time. It is obvious however that an account of the colour characters of the 
Scottish children would be incomplete which did not include an investigation on 
the two taken together as found occurring in each individual. 
It is one of the disadvantages of a private investigation as compared with 
an official one carried out by a Department of the State, that an adequately 
paid staff is not available to tabulate the enormous mass of data, the complete 
analysis of which is necessary before a full account can be given of all the facts 
which flow from the results and which lie hidden until the tabulation has been 
made. Although the author has been continuously engaged in the tabulation 
and numerical treatment of the returns so kindly made by the teachers voluntarily 
more than four years ago, he has been able only to complete the investigation in so 
far as it refers to the separate colour characters. The large mass of data bearing 
on fraternal and other relationships lie practically untouched. The tabulation of 
the combinations of the two characters has still to be made, except for one or two 
districts. The author has complete confidence that not only will he be able to get 
the funds necessary for clerical assistance to tabulate these important data, but 
that he will be personally given sufficient time to do the work. The correlations 
between hair and eye colour when such data are tabulated and the values of the 
correlations evaluated for each locality will be of great value. Not only will the 
predominant types in each district be determined but the relative homogeneity
