 health apon good standing is certainly very- 

 marked, and the symmetry of the two 

 curves for good and poor health is very 

 striking. The study of the two sexes sepa- 

 rately seems to throw some interesting side 

 lights. For the boys and girls in perfect 

 health about the same conditions are indi- 

 cated as for the two groups, but for poor 

 health it would seem that the direction is 

 given the curve mainly by the boys. The 

 percentages of girls of poor health in the 

 1st and 4th quarters of the class as to 

 scholarship were the same (26 per cent.), 

 while less than 1 per cent, of the boys in 

 poor health were at the head of the class to 

 40 per cent, of them at the foot. This 

 would seem to imply that even before the 

 adolescent stage of development the girls 

 have the power of forcing themselves to do 

 work even when vitality is low, which has 

 generally been attributed to them onlj^ at a

 responsible for many evils and probably are 

 in evidence here.
