The outbreak of the great pneumonic plague in Manchuria a few winters ago afforded the first larger opportunity to study the pathologic anatomy of this disease and to examine histologically the lesions that are produced by it. To the earlier reports and particularly to those of the American investigators, Strong, Crowell and Teague,1 are now added the notes collected by Dr. Wu Lien-Teh, director and chief medical officer of the North Manchurian Plague Prevention Service, and Prof. G.

The epithelium of the kidneys is modified by a similar toxic activity. It
