Pneumonia, with Special Reference to Pneumococcus Lobar Pneumonia.

This work is probably the most complete and comprehensive discussion of the subject of pneumonia ever published. It is the third volume of a series resulting from the "Massachusetts Pneumonia Study and Service," which Dr. Heffron ably directed from 1931 to 1935. The material is drawn not only from the results of this study but from a critical and extensive survey of the literature. Some idea of the extent of this survey is given by the number of titles in the bibliography, which is 1,471. The material is arranged in orthodox fashion, beginning with chapters on incidence and pathology. These are followed by long and thorough chapters on aspects of immunity and experimental pneumococcic infections, which are both unusually valuable and well done. A number of chapters cover the usual clinical subjects. Two whole chapters are devoted to serum therapy, in which field the author has had unusually great experience.
