Tocher* states that on an average any excess or defect in the boy population 
from the general mean in any locality is accompanied in about 70 — 90°/ o of the 
cases by a corresponding excess or defect in the girl population and vice-versa. 
Such being the case, boys and girls have been combined in this inquiry. In 
scarlet fever alone are the bo3'S and girls treated as separate units. 
. In all, 3535 observations have been made, namely : 1864 on scarlet fever 
patients, 700 on diphtheria patients, 661 on measles patients and 310 on whooping 
cough patients. 
On the Possibility of Comparing the Hospital Results with those of Tocher. 
In comparing the results obtained in hospital with those of Tocher, a difficulty 
is met with in regard to the age difference of the subjects of these investigations. 
In hospital the majority of the children on whom observations were made, were be- 
tween the ages of 2 and 12. Tocher gives the age of the school children considered 
in his survey as between 6 and 18, but the bulk are between 6 and 12 years. 
The difference in age is considerable, and might be thought to give rise to 
inaccuracy when comparing the results of these different observations, but authority 
can be given for considering the age difference as of little importance and liable
