From the foregoing table it is seen that there are about 3500 less than the 
expected number of fair-haired children, about 2300 more medium haired and over 
1300 more dark-haired. There are 2000 less blue-eyed children than expected, 
about 700 more medium eyed and over 1300 more dark-eyed children. Such 
differences, even with the large numbers dealt with in Glasgow, have a definite 
significance and are not differences which would occur in making a random draw 
of the same numbers from the general population. 
In the county and district analyses, Glasgow has been treated as a unit. The 
city has been contrasted as a whole with the neighbouring counties and also with 
the immediately surrounding population, a population which has been divided up 
into districts. In both cases, it has been shown to be unlike those outside popula- 
tions. It seems highly desirable therefore to examine Glasgow from the inside in 
order to see what is the cause of the great difference ; whether, analysed intra- 
locally, the population of the city is different in different parts of the city; and 
whether these various divisions agree with or differ from the surrounding sub- 
urban areas. 
Under the School Board of Glasgow the city is divided into ten educational 
districts. The accompanying table (Table XLVI.) gives a list of the districts and 
their respective schools : 
In order to have approximately equal numbers in the various areas dealt with 
by the author, Calton, Camlachie and Bridgeton were grouped into one pigmenta- 
tion district; Tradeston, Gorbals and Hutchesontown, three other educational 
districts, were grouped into another pigmentation district. The following pig- 
mentation districts were also constituted for the environs of Glasgow : North 
Suburban, South Suburban, East Suburban and West Suburban. The following 
table (Table XLVII.) shows how the pigmentation groups of Greater Glasgow were 
made up, while the succeeding table (Table XLVIII.) shows the actual frequencies 
of the various classes for these districts. The results of the analysis of these figures
