Sir William Arbuthnot Lane's health secrets have been open for

some time past. As he tells us in his preface to Secrets of Good Health (Heinemann, 3s. 6d.), millions of people have read in the columns of the Daily Mail and elsewhere his advice on the subject of how to keep well. This little book is no more than a recapitulation. The great doctor emphasizes in almost every chapter the dangers of constipation, declares his theory that it is the chief cause of cancer, suggests a dietary for its avoidance without resort to drastic aperients. Also he points out the importance of simple living, the dangers of too much meat and too much alcohol, especially in the form of cocktails. He suggests exercises for strengthening the abdominal muscles and reducing obesity in the less desirable of its three stages, which in jest he distinguishes as " the enviable, the comic, and the pitiable."
