The last four columns of the table of autopsies give the bacteriology of the sputum during life and the bacteria found in the bronchi, in the lungs, and in the blood of the heart after death. =Mortality of Pneumonia Following Influenza.=—From September 6 to December 15, 250 autopsies were performed on patients who had died with pneumonia at the base hospital at Camp Pike, and with few exceptions bacteriologic cultures were made from them. Although it was not possible to perform autopsies on all who died, those which were performed afford a fair index of all deaths, for throughout the epidemic of influenza and its outbreak of pneumonia approximately one half of all who died were examined after death. The relation of autopsies to deaths is shown by a comparison by weeks of the number of deaths and number of autopsies during the months of September and October. ═══════════════════════╤═══════════════════════╤═══════════════════════ WEEK │ DEATHS │ AUTOPSIES ───────────────────────┼───────────────────────┼─────────────────────── Sept. 1–7 │ 1│ 1 Sept. 8–14 │ 1│ 1 Sept. 15–21 │ 4│ 3 Sept. 22–28 │ 15│ 14 Sept. 29–Oct. 5 │ 121│ 67 Oct. 6–12 │ 191│ 78 Oct. 13–19 │ 78│ 43 Oct. 20–27 │ 22│ 15 Oct. 28–31 │ 8│ 6 │ ———│ ——— │ 441│ 228 ───────────────────────┴───────────────────────┴───────────────────────
