National Health. By B. W. Richardson. (Longmans and Co.) —Dr.

Richardson deserves thanks for this capital abridgment of Sir Edwin Chadwick's " The Health of Nations." It will serve to remind many of us of the pressing needs of our populations, and to recall more than ever the saying that dirt makes crime. Sir Edwn Chadwick's views on educa- tion and sanitation are well known, but not so well known as they might be. In this volume we have his theories and obser- vations reduced to an easy compass, and every one can study for himself school-education, the half-time system, and the drainage of thickly populated districts ; it will also present matter for deeper and more searching study.
