The number of children* with jet-black hair is too few to be considered 
separately. 
The fact that the number of dark-haired children in the schools we have 
selected are not in excess of the number of dark-haired children in Scotland 
as a whole, leads me to think that the selected schools are schools without a large 
foreign element and consequently not the most satisfactory schools for a discussion 
of the influence of race, as measured by hair and eye colour on height and weight. 
It has been pointed out by Mr Tocher that excess of medium or brown hair, 
of medium eyes and dark eyes is associated with more thickly populated regions, 
which in turn are also regions of excess of foreigners.

The hair scale has been arranged roughly in order of pigmentation ; red comes 
first since it contains fewer pigment granules, and black last since the darker the 
hair the more pigment granules, and it will be noticed that pigmentation increases 
slightly with age. Differences in height and weight are slight and an examination 
of the correlation coefficients in Table III. will show that when corrected, for age, 
the association between hair or eye colour and height and weight is insignificant. 
A rough correction for age can be made on the average height and weight for 
each hair and eye colour. The deviation of the mean age of each eye and hair 
colour group from the mean age of the total is obtained and is multiplied by the 
differences in height and weight of children of 10 and 11, aud the result so obtained 
is added or subtracted to the mean height or weight already found for each age 
group — the results so found are giveu in Table II. 
Only children of 7 to 14 years inclusive are considered.
