Drs. Fishberg and Kline, authors of the paper with the above title, published in the Archives of Internal Medicine, January 15, 1921, p. 61, request the addition of the following paragraph to their paper:
The occurrence of fusiform bacilli and spirochetes, not only in the exudate over the gums but also in the gangrenous lung tissue, lends support to the belief that this is a case of aspiration pneumonia followed by pulmonary gangrene in which innumerable mouth organisms, Vincent's spirochetes and fusiform bacilli from the gingivitis were aspirated into the lungs, the mouth organisms producing the widespread consolidation and the spirochetes the associated gangrene.
