of the bacteria, most of which exhibit a lanceolate form and 

 have distinct capsules. The disease is thus shown to be a 

 bacteremia unassociated with conspicuous tissue-changes. 



In such cases the lungs show no consolidation. Even if 

 the inoculation be made by a hypodermic needle plunged 

 through the breast-wall into the pulmonary tissue, pneu- 

 monia rarely results. Monti claims to have found that a 

 characteristic croupous pneumonia results from the injec-

 the stage of red hepatization of croupous pneumonia. The pneu- 

 monia has been preceded by chronic pleuritis, which accounts for the 

 thickened fibrous trabeculae extending into the tissue, and which may 

 have had something to do with the peculiarly prominent appearance 

 of the bronchioles throughout the lung.
