That the curve of typhoid incidence, the B. coli content of a polluted stream and the B. coli output of the observer follow the same seasonal variations is shown. There is apparently a variation in the biological equilibrium of the body and a changed rate of multiplication of organisms. There is opportunity here for interesting bacteriological investigation.
