of the higher rate of infection on certain wards, we have brought 
together in Table 2, the amount of infection upon each ward and in 
each section, together with the history of the patients with regard to 
the above points. 
In our total results it was noted that women were more frequently 
infected (10.21 per 100) than men (6.45 per 100) and that this sex 
inequality was especially marked among the Connecticut cases taken 
separately, the Connecticut women giving 17.72 infections per 100 
and the Connecticut men 8.96 infections per 100. 
As would be expected, accordingly, we find the most heavily infested 
wards are female wards. The highest rate of infection foimd on any 
male ward was 37.77 per 100 and the next 3 highest male wards showed 
only 15.52, 14.29, and 14.28 per 100, respectively, while among the 
women the 4 highest wards gave, respectively, 75, 57.14, 53.33, and 
53.33 per 100. Two other female wards showed 23.08 and 23.56 per 
100, and still 6 others showed 15 per 100 or over. 
It is evident, then, that differences in ward infection may be due 
in part at least to that greater tendency to intestinal worms among 
women which we have already noted in our general results. 
That this is not the entire explanation, however, is at once appar- 
ent when we consider that among the female wards alone the variation 
in the amount of infection was no less striking. Seven female wards 
showed no infections, and on the remaining 18 female wards the amount 
of infection varied from 3.57 to 75 per 100 patients. Furthermore, 
while we have besides the 7 uninfected female wards, 4 female wards 
which gave less than 10 infections per 100 (5.57, 6.66, 8.33, and 8.33 
per 100), there are 3 male wards which gave about 15 infections per 
100 (15, 14.29, 14.28 per 100) and one male ward giving 37.77 infections 
per 100. It is evident also from the figures already given that there 
is a variation of from 2.86 to 37.77 infections per 100 on the infected 
male wards alone, and 6 male wards are uninfected. 
Evidently there is a wide range in the amount of infection upon the 
various wards wholly independent of what might be explained by the 
greater frequency of intestinal parasites among women. 
Taking up the consideration of the age and nativity of the patients 
and the length of time they had been in the hospital, it must be borne 
in mind that the variation in the amount of infection due to each of 
these factors, as appears in our previous pages, is too small to account 
for the wide difference which we found in the amount of infection upon 
the separate wards and sections, and that if the relatively high per- 
centage of infections found upon certain wards was due in any consid- 
erable degree to any conditions of age, nativity, or length of institu- 
tional life among the patients upon those wards, these conditions must 
be present in combination and in a very apparent and striking manner. 
Though we have studied Table 2 carefully, a mere glance is sufficient
