This excellent description of malaria follows the classic lines of discussion of history, geography, the parasite, the mosquito, epidemiology, symptoms, therapy, etc. Indeed the division of pernicious fevers into various forms (tetanic, hemiplegic, choleraic, algid, cardialgic, bilious, etc.) takes one back to nineteenth century medical writing. The chapters on immunity and animal experimentation are highly instructive; it is unfortunate that so much of the recent work on malaria is still not to be published for military reasons. This book represents, however, an admirable summary of the subject, and the fact that much of the material was reviewed by special experts adds a note of authorty to all that is said.
