This book, though brief, represents an attempt on the part of its authors to evaluate the present status of chemotherapy and serum therapy in the treatment of pneumonia, based on the experience of a comparatively large and active public health service, especially in Massachusetts. It attempts, however, to deal with the subject, namely, pneumonia, with reference to the entire problem of the management of this infection. It treats in its subject matter the etiology, the diagnosis, the recognition of types of pneumonia, the immunity factors and the prognosis, in addition to its primary purpose, namely, chemotherapy and serum therapy. For the reason that it deals with the entire problem this book should be of considerable interest to the general practitioner, although its value as a reference book is questionable.
The authors attempt to show, although inconclusively, that the identification of the inciting organism is of great importance. No convincing evidence
