THE RELATIVE STRENGTH OF 



related to a small extent with lesser weight of their 

 sons, the coefficient being '12 for all schools in 

 Glasgow and '14 for Edinburgh, and we may say 

 that the results obtained from the two distinct sets 

 of statistics are well in agreement. 



(2) That the employment of mothers is also cor- 

 related with lesser height of sons, and this correlation

is somewhat larger than that found for weight in 

 Glasgow. The effect of the employment of mothers 

 on the height of sons in Edinburgh is measured 

 by the coefficient '09, which is distinctly lower than 

 that found for all Glasgow. The Edinburgh schools 

 are, however, probably closest in grade to the 

 Glasgow Group A.
