The Nazi government in Germany has caused medical men to review rather carefully the so-called medical indications for the operation of sterilization. The first section of the monograph by Bauer and Mikulicz-Radecki is a discussion of the indications for this operation, which is now required in Germany. It also gives the legal forms that are used in cases in which sterilization is employed. The second section of the book describes the various operations that may be used for the sterilization of men. The third section deals with the types of operations suitable for the sterilization of women. The operative procedures are shown in the illustrations. Eight pages of bibliography and the index complete the volume. Those who are interested in the study of medical sterilization will find this an interesting contribution to the subject.
