This work is intended to provide, for ship surgeons and colonial physicians, a general résumé of the facts on malaria, its treatment, recognition, etc. It meets this purpose well. Our knowledge of malaria has greatly increased within the last few years, but this work is well up to date. The illustrations of the phases of the malarial parasites are good, as are also those of the malaria-bearing mosquitoes, and the graphic temperature curves throughout the text are also instructive. The staining methods are given in simple forms and the book is as a whole one that the physician in the tropics will find helpful. The English translation has been excellently done.
