Since the middle of the last century British and French physicians have shown steadily deepening appreciation of differences between surgical procedures for children and those for adults, as evidenced by books and articles in medical literature. As early as 1863, children's surgery was considered so important by the Council of the Medical Society of London that Mr. Thomas Bryant was invited to present the Lettsomian lectures on that subject. Physicians in America, however, have apparently been more concerned in developing the medical aspects of pediatrics; with the exception of the excellent volume by Kelley, which was soon followed by that of Willard, little attention has been paid to the surgical side of the picture. In the past few years, however, articles have appeared in American medical literature which indicate a tardily awakening interest. This should receive a healthy impetus from such an excellent monograph as the subject of this review.
