Abstract
Four separate strains of mice have been tested for their relative susceptibility to per os infection with the Type II bacillus of mouse typhoid (Bacillus pestis caviæ), 300 to 600 individuals of each strain having been employed in the course of 12 months. In confirmation of a previous paper, clear-cut differences in the susceptibility of these strains have been shown to exist. In general, the colored strains were distinctly less resistant than the albino strains.
