Ground-water theory, the theory that the development of certain epidemics (cholera, typhoid fever) coincides with a low level of the ground-water; the pathogenic germs are not carried directly from the sick to the well, but are received into the soil and there undergo, when the soil is dry, a "ripening" process.
By Stedman, Thomas Lathrop
