New Method of Correlation 
Illustration I. Relation of Anaemia to Age. I take the data from the last 
Report of the Education Committee of the London Coimty Council. Report 
of Medical Officer. Particulars as to age and " colour of blood " are given for 325 
bo} s at Laxon Street and 364 boys at Sirdar Road schools ; and for 367 girls at 
the former school and 330 girls at the latter school : see p. 19. Sirdar Road, Notting 
Dale, is described as " one of the poorest schools of London in the midst of a 
migratory, criminal, and thoroughly degenerate and poverty stricken population." 
Laxon Street is also in a very poor district ; lack of employment, improvidence 
and drink are exceedingly common in both districts. Either different standards 
of anaemia were used in the two schools, or the Laxon Street school shows far 
more anaemia than the Sirdar Road. The ages covered are 7 to 13. Putting 
" pale " and " very pale " together, the latter " blood colour " only occurring m about 
5 p.c. of the children dealt with, we have 
BOYS.
