—In The Journal, Nov. 16, 1918, p. 1700, an abstract from Policlinico, Rome, describes the cultivation by Ciauri of a bipolar micro-organism in conjunction with gram-positive rods from the blood and sputum of cases of severe influenza. We have recently isolated from a pleural effusion following influenza a bacterium similar in some respects to the bipolar organism described by this author. The following characteristics were noted: The organism was rod shaped, often oval, gram-negative, with distinct bipolar staining and a tendency to variation in morphology. No motility was observed. It grew on plain agar best at 37.5 C., though not heavily, and aerobic conditions were more favorable than anaerobic. Acid was not produced in glucose, lactose or saccharose agar. Gas was not produced in glucose bouillon. Gelatin was not liquefied and litmus milk was not coagulated or rendered acid. Indol production could not be satisfactorily determined because
