This volume contains the more important activities of the Chinese plague prevention organization in Manchuria. It includes the history of the service, epidemiologic, pathologic, clinical and preventive studies on pneumonic plague, summary of cholera outbreaks in China, and other medical problems undertaken by the service. An important part of the volume is an up-to-date tabular presentation (p. 423) of rodents, other than domestic rats and mice, known to suffer from plague. The common English and scientific names, geographical location and source references for each species are cited. Similarly (p. 433) there is tabulated a list of fleas recovered from rodent reservoirs of plague. Although not integrally connected with the title, one of the most valuable chapters in the book deals with the early days of Western medicine in China. Much of the information has been previously printed elsewhere, but its inclusion in a single comprehensive volume is probably justified.
