Primary staphylococcic pneumonia has been adequately described as a clinical entity. Chickering and Park1 reported 155 cases of Staphylococcus aureus pneumonia occurring during the influenza epidemic of 1918. At this time there were 8,100 patients with influenza at Camp Jackson, S. C., approximately 1,400 of whom later developed inflammatory changes in the lungs. The picture, as described, was one of over-whelming sepsis, the temperatures ranging from 104 to 106 F. with frequent remissions. A peculiar "cherry red indigo blue cyanosis" was a regular accompaniment of the picture. Physical signs were diffuse and surprisingly sparse in view of the extensive consolidation on roentgenographic examination. The sputum was described as being friable, purulent and of a dirty salmon pink color resembling anchovy sauce or the "contents of an overripe furuncle"; on culture this yielded Staphylococcus aureus as the predominating organism. Because of technical difficulties, few blood cultures were taken, and two
