It also appears from the above figures that if foreign-bom males 
and females are considered separately, the patients of German, of 
English, and of Irish nativities do not maintain the same order as 
regards the frequency of helminthiasis in the two sexes. For males, the 
highest rate of infection was foimd among the English born, the next 
highest among the Irish bom. and the lowest rate among the German 
bom: for females, the highest rate of infection occurred anions Irish- 
- C 7 C 
born patients, the next highest among Germans, and the lowest rate 
among the women of English nativity. 
The greater frequency of intestinal worms among English-born males 
than among English-born females held even at the Connecticut hos- 
pital. where the rate of infection in general was considerably higher 
among the female patients. As will be seen, however, we are reduced 
to very small bases in making this comparison between males and 
females among the English-born patients at the Connecticut hospital, 
and the results would hardly be of interest except when taken in con- 
nection with the comparisons between the sexes among patients of 
foreign nativities given above:

HISTORY OF PATIENTS PRIOR TO ADMISSION TO THE HOSPITALS. 
Our statistics under this head are confined to the patients at the 
United States Government and the Connecticut State hospitals, 
sufficient data not having been obtainable for the children at the 
orphanage to consider them in this connection. 
Place of eesedexce. — Our material is not well adapted for study- 
ing the variations in the prevalence of infection in different localities. 
It was desirable in the first place to eliminate as completely as possible 
the influence of institutional life, and this has been done by selecting
