Here in one volume are collected all the facts concerning the history, habits of life, anatomy, physiology, pathology and social relations of the anthropoid apes. These are the monkeys nearest to man in appearance, habits and physiologic functions. There are many illustrations, innumerable quotations from the literature and the records of special investigations which indicate how closely allied the anthropoids really are to man and woman. The great question as to whether or not these apes talk receives adequate consideration. Apparently some species can be induced to make sounds indicating their desires. The book is exceedingly well written and handsomely printed.
