The control of fertility

printed. The editors have used a rather curious technique of organi¬ zation, introducing some apparently meaningless repetition. In this com¬ pendium, many authors are repre¬ sented by more than one published work. But throughout the two vol¬ umes, wherever the individual's work appears, the same biographical note is reprinted. Thus the identi¬ cal note on R. M. Waters appears on pages 540, 548, 645, and 708, all in volume one. Inclusion of both subject and name indices enhances the useful¬ ness of these books. They contain a matchless collection of material now for the first time easily acces¬ sible. The resident and practicing anesthesiologist will find the vol¬ umes both interesting and educa¬ tional. And they will prove invalu¬ able to the medical historian.
