In view of the reputation and experience of the authors, it is not surprising that they have done this so well. The volume is prepared primarily for the British Empire, but this means that practically all the so-called tropical diseases are considered. There are sections dealing with febrile diseases caused by protozoa by spirochetes, by organisms of uncertain origin, such as yellow fever and dengue, and by bacteria, such as plague and undulant fever. There are also sections on diseases caused by helminths, bowel diseases, skin diseases, snake-bite, deficiency diseases and diseases caused by heat and light. Of particular interest to physicians
