This was written especially as a textbook for veterinary students, but it lists fifty-seven parasites affecting man. Forms that are relatively unimportant from the veterinary aspect, such as Necator americanus, are accorded but little space. Parasites of veterinary significance are discussed briefly as to life cycles, pathogenicity, symptoms, diagnosis, treatment and prophylaxis. A convenient host-parasite list gives all the parasites of each host, together with the page reference. The book is not intended to be a complete and exhaustive treatise on all human and animal parasites. As a ready reference work for the more important forms, it should be of service.
