The great popularity of this small book is attested by the fact that the present edition is the sixteenth since 1893. The book is divided into six parts. The first deals with the attitude and position of the fetus, the second is concerned with the mechanism of labor, the third takes up version and extraction, the fourth describes forceps operations, the fifth is a discussion of manual extraction of breech presentations and the sixth is devoted to destructive operations. There is an additional brief section on cesarean section and hebosteotomy. One seventh of the book is devoted to destructive operations. This seems a disproportionately high allotment of space to this subject. Although the book was received for review in October 1936, the publishers have issued the book as having been copyrighted and printed in 1937. The book is clearly written and the illustrations are highly instructive.
