The subject matter of this book was originally prepared for a discussion on "Primates and Early Man," which took place at the meeting of the British Association for the Advancement of Science in 1932. Monkeys and apes were used as experimental subjects because they are suitable for the investigation of certain diseases or for the analysis of physiologic mechanisms. The evolution of man from the animal world can be traced by the correct classifications of the animals, the apes and the monkeys, which most closely resemble him in structure. The author uses facts derived from physiologic and behavior experiments in arranging man, apes, monkeys and lemurs in a systematic series. He shows how the functional evidence supports the evidence of gross morphology. A taxonomic and phylogenic survey is given of the results of experimental investigations on these animals. The author believes that a study of the functional characteristics of the
