ON ANTHROPOMETRIC INVESTIGATION IN THE BRITISH ISLES. 357 
On closely examining the hair of the head of any individual, it was 
observed that different parts of the hair would have to be classified under 
different headings, so that an expression for the value of the whole 
coifure rather than an individual lock must be sought for. This difficulty 
has been avoided by arranging the samples of hair in plaits, so that the 
effect of light reflected from them at different angles can be noted. The 
general definition of the colours of the hair corresponds to that given by 
Beddoe. 
C. Irts CoLours. 
As regards iris colour, it was decided to adopt a scale with four divi- 
sions—blue, grey, neutral, and brown. Artificial eyes, corresponding to 
the scales of these divisions, have been obtained, but some difficulty exists 
in exactly defining the boundaries, and for this purpose the scale of arti- 
ficial eyes used by surgical instrument makers contains some 150 to 200 
different shades ; so that, if thought advisable, a very exact scale of descrip- 
tion could be adopted. This, however, would only be suitable for use in 
large laboratories. For field-work and use in schools the scheme of 
classification adopted above would appear preferable. The standard 
scale of eyes contains central examples of brown, grey, and blue. All 
eyes lighter than the standard should be classed as light brown and all 
eyes darker than the standard as dark brown, &c. A very dark blue 
eye on this scale should be classed as dark blue, and not as dark, 
the division into which it fell in Beddoe’s scheme. The advantage 
of separating the class of light eyes into grey and blue is that it enables 
comparisons to be made with German observations. The French scale, 
on the other hand, prefers to recognise only two varieties of eye, light 
and dark. 
D, SCHEDULES. 
A series of Schedules of proposed anthropometrical measurements for 
the use of schools have been drawn up :—

tween the trochanters. 
Schedule 1 consists of measurements designed to show the progress 
of the individual child, and are those on which the greatest reliance 
is placed from the hygienic aspect. However, considerable risk of a false 
comparison may exist, since children belonging to different races or stocks 
differ at all ages, even in these dimensions.
