BIGELOW PROFESSOR OF BIOLOGY AND DIRECTOR OF THE SCHOOL OF PRACTICAL ARTS, TEACHERS COLLEGE COLUMBIA UNIVERSITY New York THE MACMILLAN COMPANY 1916 _All rights reserved_ COPYRIGHT, 1916, BY THE MACMILLAN COMPANY. Set up and electrotyped. Published June, 1916. Norwood Press J.S. Cushing Co.--Berwick & Smith Co. Norwood, Mass., U.S.A. To THE MEMORY OF DR. PRINCE A. MORROW WHOSE GREAT FAITH IN THE ESSENTIAL GOODNESS OF HUMAN NATURE LED HIM TO BELIEVE THAT THE PROBLEMS OF SEX HAVE ARISEN FROM IGNORANCE AND THAT EDUCATION IS THE KEY TO THEIR SOLUTION PREFATORY NOTE Many of the lectures printed in this volume have formed the basis of a series given at Teachers College, Columbia University, during the summer sessions of 1914 and 1915, and during the academic year 1914-1915. Others were addressed to parents, to groups of men, to women's clubs, and to conferences on sex-education. In order to avoid extensive repetition, there has been some combination and rearrangement of lectures that originally were addressed to groups of people with widely different outlooks on the sexual problems.
