THE PRACTICE OF BIRTH CONTROL By Enid Charles
This is primarily a detailed statistical analysis of the acceptability and reliability of various contraceptive methods, based upon two considerable questionnaires and the follow-up reports of a clinic. In its critical conscientiousness, breadth of vision, and wisdom it compares very favourably with many recent books on the subject.. _ Moreover, unlike most of them' it queries how far differences and fluctuations in fertility may be due to biological, rather than contraceptive, causes. Dr. Charles' fellow-workers will find the book, The Practice of Birth Control (Williams and Norgate, 10s. 6d.), an essential and welcome addition to their libraries, while the lucidity of its writing enables the reviewer to recommend it unreservedly to the laity whose interest in the subject is purely personal. It is doubtful, however, whether the comparison (pp. 143-144) with the Census of 1911 is valid.
