The art of brief but adequate expression is exemplified in this excellent little book, which covers all the essentials of practical obstetrics. As indicated by the title, it is an atlas, well supplied with amply descriptive legends. The illustrations are chiefly line drawings in black and white well suited to the text. The two colored plates are excellent; one illustrates a full and clear description of the fetal circulation, with explanatory drawings. The authors would have done well to omit the illustration on page 138 showing the method of administration of saline solution into both breasts. This practice has long since been replaced by hypodermoclysis in safer portions of the body, such as the thighs, flanks or axillary regions. With this one exception the book is heartily recommended to nurses, students and practitioners of obstetrics as well as to midwives, for whom the book was prepared.
