And lastly, the frequency with which an inflammatory œdema occupied the lungs in the cases of influenza was in quite striking contrast with the dry fibrinous lesion of common pneumonia. This wet state of the lung was but a stage in the inflammatory process varying in its extent in the different periods, but nevertheless inducing a character in the early pulmonary lesions which was quite foreign to our usual finding. This wet state also assisted in modifying the subsequent picture so that when the lung assumed its gray appearance it was rather of a slimy character than of the firm dry nature. In this late gray stage the slimy lung somewhat resembled the appearance of unresolved pneumonia where this condition had been brought about by a new infection upon the original cause of the pneumonia. It is incorrect in influenza pneumonia to speak of the lesions as lobar pneumonia or broncho-pneumonia if by these terms we have in mind the pathological characters observed in the pneumococcic pneumonia with its lobar or bronchial distribution. Influenza-pneumonia appeared with both lobar and lobular characteristics. Nearly every case had both types of lesions present, but the nature of the inflammatory process is so decidedly different from that of the ordinary endemic pneumonia that a confusion in the interpretation is likely to arise and in fact has already raised a considerable polemic. Influenza-pneumonia is commonly lobar, lobular or bronchial in distribution. It is, however, not of the characters that are associated with the lesions designated under these terms. When, therefore, we here use the word “lobar” we mean lobar _in distribution_ but not lobar in type. As will be seen from our table, it was usual to have multiple lobes involved. But the lesions, not only in the different lobes varied in their character and distribution, but even within the same lobe a variety of types was present.
