The progress of Psychology during the last half century has been both rapid and extensive. Along the lines of theoretical inquiry significant and far-reaching results have been attained; the methods of experimental research have been successfully applied to a wide range of mental phenomena; and it is now generally recognised that in connexion with the subject-matter of many branches of scientific pursuit psychological problems of fundamental importance present themselves for solution. The object of the _Cambridge Psychological Library_ is to furnish a series of books, written by men actually engaged in the work of research, dealing with the various subjects that come within the field of Psychology. The extent of this field may be gauged from the titles of the volumes given below, some of which have already appeared, the others being in preparation.
For the reasons indicated, the _Cambridge Psychological Library_ will appeal not only to Psychologists but also to students of many other departments of scientific thought and investigation, such as Philosophy, Sociology, Art, Comparative Religion, Anthropology, Physiology, Zoology, Medicine, Education and Industrial Efficiency.
