Mrs. Gascoigne Hartley has a great many wise things to

say in her book on Sex Education and National Health (London : Leonard Parsons; 6s.). Perhaps she is a little run away with by her subject—most of us are when we write books. She paints the present too luridly and is too certain of the efficacy of her remedies; but there is no doubt that what she has to say Is very unterial. We recommend her book to the attention of all school masters and mistresses, and thoroughly endorse the opinion of the writer of the preface when he suggests that

co-education—at any rate up to public school age—would go far in the cure of many of the evils of the present school systems.
