In 16 of 21 autopsies hemolytic streptococci have been obtained from the blood in pure cultures, in one instance associated with pneumococcus. With associated empyema, pericarditis or peritonitis, the same microorganism has been found in the pleural cavities, pericardium or peritoneum. Furthermore, microscopic examination has demonstrated the presence of chains of streptococci in the affected interlobular tissue and in much greater abundance in the distended lymphatics. Nevertheless in 2 instances no streptococci have been found. These cases are as follows: =Autopsy 330.=—Illness began with symptoms of influenza ten days before death; signs of pneumonia were recognized three days before death. There is firm, gray red consolidation of the entire left upper lobe; the interlobular septa are here indicated by yellow lines of obvious suppuration and thick puslike fluid exudes from the cut surface of the consolidated tissue. The upper half of the left lower lobe has undergone gray hepatization, but here there is no distention of the interlobular septa. There is fibrinopurulent pleurisy on the left side with accumulation of 400 c.c. of fluid. Pneumococcus IV is obtained from the blood of the heart and from the lung. In the suppurating tissue diplococci which stain by Gram’s method are present in large number; there are a few short chains.
