was then reluctantly abandoned and the analytical table with broad classes was 
adopted as one likely to lead to the least error in determining the colour characters 
of the children. The accompanying schedule (Table II., much reduced size) was 
adopted by the Committee, the table (Table I.) with the description of the classes 
being printed on the back of each schedule. 
The form of schedule and descriptive analytical table being definitely settled 
the author drew up a circular letter to the teachers which was adopted by the 
Committee*. 
Mr John Gray's name was, with the consent of the Committee, associated 
with the writer's in the circular, as it had been mutually arranged that, after the 
data had been collected and summarised by the author, a joint paper should be 
prepared. This idea was departed from, at a later date, at Mr Gray's suggestion. 
With the Committee's approval he has, instead, written a short memoir illus- 
trating his method of dealing with the observations grouped into districts, from 
Tables XL, XII., XIII. and XIV. of Appendix supplied to him by the writer who, 
on completing the statistical analysis, gladly supplied Mr Gray with the tables 
referred to"^. District grouping suited the purpose he had in view of repre- 
senting, by contour lines, the imaginary up and down steps by which lie assumes 
one locality gradually to merge in intensity of colour into adjacent ones. The

*Deab Sir, or Madam, 
As you may have seen reported, this Committee proposes, with your kind assistance, to 
carry out a survey of the colour characteristics ot the school children of Scotland. 
We heg to enclose the neces.sary form, and we should feel very much obliged if you will kindly 
record the names and colour characteristics of the children of your school for the use of the above 
Committee. 
The purpose of this survey of the colour characteristics of the children is to collect statistics in 
order to elucidate racial characters, the laws of heredity, and the general problem of evolution. 
The Committee suggests that, when convenient, the teacher in charge of each class should first have 
the names and ages, and if possible the relationships, of the children recorded in the sheets. After this 
has been completed, he or she could then, at convenient times, call up the children, five or six 
at a time, and note the colour of the hair and the colour of the eyes, following the instructions on the 
analytical table on the back of each observation sheet. 
We may briefly mention that in carrying out this Survey, besides the jirivate goodwill of hundreds 
of Teachers, the General Committee of Management of the Educational Institute of Scotland support 
the idea. The following resolution of the General Committee was adopted in December last : — 
" That the G.C.M. recommend the Members of the Institute to afford whatever support it 
may be in their power to give towards the carrying out of a Pigmentation Survey of School 
Children in Scotland." 
The Royal Society is aiding the survey by a grant from the Government Funds, while the results, 
besides being published in scientific journals, will be printed as a separate memoir. This memoir 
will contain a complete list of the contributing teachers and of the statistics forwarded from each 
school. We have provided for the survey of over 750,000 children , which is the estimated number in 
Scotland. 
We sincerely trust you will, without inconvenience to yourself, supply the Committee early with the 
particulars asked, and do what you have in your power to assist in a survey which has such a high 
bearing on the racial characters of the Scottish people. 
t These tables as supplied to Mr Gray do not, of course, contain the figures from the late Eeturus.
