Pathogenesis.—Liver tissue containing this bacillus is rery pathogenic for guinea-pigs when injected subcutaneously, and causes an extensive in- flammatory oedema extending from the point of inoculation. Pure cul- tures of the bacillus are less pathogenic, and the few experiments which I made in Havana gave a somewhat contradictory result, recovery having occurred in one guinea-pig which received a subcutaneous injection of ten rninims of liquid from an anaerobic culture in glycerin-agar, while another died at the end of twenty hours from a subcutaneous injection of three minims, with extensive inflammatory oedema in the vicinity of the point of inoculation.
