The bacillus exciting the disease was discovered simulta-neously by Kitasato and Yersin (1894) during an epidemic of the bubonicplague in China. It is found in large numbers in the seropurulent fluid from the recent buboes charac-teristic of this disease and inthe lymphatic glands; morerarely in the internal organsexcept in pneumonic caseswhen the lungs and sputumcontain immense numbers. Itoccurs in the blood in acutehemorrhagic cases and shortlybefore death. It also occurs inmalignant cases in the feces ofmen and animals. The bacillus,as we have stated, is closelyallied to the hemorrhagic septi-cemia group. Morphology.—The bacilli insmears from acute abscesses orinfected tissues are, as a rule,short, thick rods with roundedends. The central portion of the bacill
