It also attempts to indicate the general prin- ciples on which the comparatively young science of parasitology is based. The author’s lifetime study of parasitic animals and the diseases which they carry has enabled him to produce a remarkably authoritative yet highly readable account. The author begins his work with a lucid discussion of just what a parasitic animal is and what it is not; he then provides a general preview of the various kinds of parasitic animals. The remainder of the book takes up, in logical order, the life histories rlf all &e important parasitic animals that afflict man (including hookworms, roundworms, threadworms, flukes, tapeworms, the malar.ial parasites, trypanosomes, leeches, ticks, lice, and many others). He explains how they enter the human body; how they live at the expense of the human; how they reproduce; how some of them have evolved mul- tiple and complex life cycles that have widened their distribution in organic nature; how they cause disease in humans; how they can be best avoided and eradicated; and other useful and interesting information. The book is extremely well illustrated with 14 photographs and 67 line drawings showing many of the parasites in various stages of growth, eggs, life histories, etc. The account is nontechnical in level, so that anyone interested in the. subject should be able to follow it without difficulty. The book will be extremely valuable as a reference source for medical students, biologists, chemists, laymen in?eres?ed in natural history, and all medical workers, social workers, or administrators whose work involves main- taining health standards in tropical or subtropical countries.
