Excluding Hymenolepis nana , the rates of infection in the two 
sexes with all other worms found were: Hoys, 13.89 infections per 
100; girls, 19.61 infections per 100. 
Among the 1,010 patients examined at the Connecticut hospital, 
the frequency of intestinal worms among females was sufficiently 
greater than the frequency among males to overcome in the total 
results the higher rate of infection found among males both at the 
Government hospital and at the orphanage. The figures for the 
Connecticut hospital are as follows :

Whipworms, eel worms, and the fat tapeworm gave a higher per- 
centage of infection among Connecticut females than among Connec- 
ticut males ; pinworms and Cochin China worms showed a higher rate 
among males than among females ; hookworms were equally prevalent 
in the two sexes, and the dwarf tapeworm was not found among our 
Connecticut cases. The comparative statistics in question are as

It is evident that the higher rate of total infection in females than 
in males found in the Connecticut institution is almost wholly due to
