While both modes of infection are probably true, the first at least has received a very positive confirmation at the hands of M. Lesage. At the request of Sevestre, Lesage investigated bacteriologically five cases presenting the requisite clinical features. In four cases, there were patches of bronchopneumonia, one of which had suppurated. In the other case there was merely a pulmonary congestion. In every case the B. coli commune was found in the pneumonic patches and in the congested lung. Moreover the B. coli commune was the only microörganism found in the pneumonic patches.
