colour characters singly or jointly with one another were wanting. These schools 
have not been dealt with in this memoir. The data proper therefore consisted 
of fully complete returns from 2288 schools containing the records of the names, 
ages, sex, fraternal and cousin relationships, and colour characters of 257,766 boys 
and 244,389 gii'ls, a total of 502,155 children. Although there was a good deal 
of further correspondence with the teachers, only a few more returns were received 
after November, 1904. These have not been included in the district analysis 
which was in operation before the returns were received but have been included 
in the division, county and general analyses*. The work of classification and 
tabling, which was commenced as soon as practicable, was soon in full operation. 
The response of the teachers had been remarkably enthusiastic and complete. 
The survey was an accomplished fact. 
On behalf of the Committee the writer begs to acknowledge its great obliga- 
tions to the teaching profession in Scotland for so promptly responding to the 
invitation of the Committee to carry out the desired observations. The writer 
also wishes to record his personal sense of indebtedness to the teachers and to 
thank them very cordially for all the pains and trouble they Lave taken in making 
the elaborate returns so vital to the success of the scheme. The credit of the 
accomplished survey is undoubtedly due to the teachers. Without the recognition 
* The late returns came from the counties of Lanark, Renfrew, Banff, Elgin and Inverness and 
belonged, in the district scheme, to the first, fourth, eighteenth and ninety-lirst districts. The total 
results of observations for these districts are however given in the Appendix tables and not the slightly 
smaller figures on which the district analysis was made. The figures for the later returns are also of 
course given along with the others under their respective parishes and counties and were included in all 
analyses except the district one. The only points therefore to be noted are (1) that the district analysis 
is based on the slightly smaller general totals and (2) that, in the analysis of Districts I., IV., XVIII. 
and XCl. , the late returns (not to hand at the time of analysis) are excluded.
