In A, B, and C, males and females occupy opposite ends of the build- 
ings, the men and women being so entirely separated that from our 
point of view they may be considered as in separate buildings. 
Building D is devoted entirety to females. We have, then, 7 divisions, 
showing the following relative amounts of infection, arranged in ascend- 
ing order: 
1. [A males].. 
2. [A females], 
3. [B females] 
4. [C males], . 
5. [B males].. 
6. [C females] 
7. [D females]

The only change in the order of buildings in considering the male 
and female departments separately is in the position of the male sec- 
tion of Building B . The males in this building not only showed a higher 
rate of infection than the females in the same building, but a higher 
rate than C males. With this exception, the rate of infection increased 
in both males and females from A to B, B to C, and C to D, the females 
in A and C, but not in B, showing a higher rate than the corresponding 
males. 
The amount of infection in the different sections accordingly is 
found to vary from 2.56 per 100 in the male section of building A to 
61.33 per 100 in building D (females).
