This is essentially a teaching text for the undergraduate. The subject matter is presented in outline form with specific points listed in an a-b-c fashion so that the student has, in essence, a syllabus of that part of his course in obstetrics which deals with labor and delivery. It was evidently written with the very laudable idea that medical students should know how a fetus gets through the pelvis, what can happen to prevent the normal progress of parturition, and how the obstetrician should manage normal and abnormal labor. The material is presented in the individual chapters in a remarkably clear and readily understood manner. There is nothing notably new or different in the author's teachings, and most obstetricians in the United States will find little fault with their obstetrical practices. The authors seem to emphasize the use of roentgenpelvimetry and apparently take a somewhat dim view of external version.
