*In this book the writer thereof seeks to convey to women particularly to young wives and women expecting to be married certain important facts of knowledge, certain necessar y information, which all such women should possess, but which few are given the opportunity to acquire. It would seem to require no argument to convince a rational individual that before a woman is capable of intelligent motherhood she should be made acquainted with the physiological processes which are involved in the sexual functions leading to the state of motherhood; but we are confronted by the fact that few young women are given such instruction.*
