In 2 instances (Autopsies 285 and 346) among this small group of cases, pneumococci but no hemolytic streptococci were found in the sputum several days before death, whereas death occurred as the result of secondary invasion with hemolytic streptococci and no pneumococci were found at autopsy. It is probable that this sequence of events is not uncommon. B. influenzæ finds its way into the bronchi and pneumococci follow it; pneumonia limited to peribronchiolar alveoli may occur in consequence of this invasion. Later hemolytic streptococci may follow the same path and cause death with bacteremia. =Hemorrhagic Peribronchiolar Consolidation.=—Peribronchiolar pneumonia accompanied by diffuse accumulation of blood within the alveoli is one of the most frequent complications of influenza. The lung tissue is laxly consolidated, and on section there is a homogeneous dull deep red background upon which are seen small gray spots (1.5 to 2 mm. in diameter) grouped in clusters about the smallest bronchi (Fig. 5). Wide areas of lung tissue are implicated and the lesion is more common in the dependent parts of the lung than elsewhere. In common with other forms of bronchopneumonia the lesion is in most instances associated with changes in the bronchi; in 55 instances of hemorrhagic bronchiolar pneumonia purulent bronchitis was found in 43 instances; it is noteworthy that purulent bronchitis often is not evident in the presence of pulmonary edema and edema is not infrequent with this pneumonic lesion.
