Self and Superman, by' Mr. L. E. Eeman (Christopher, 7s.

ad.), is a curious book on nervous control, relaxation, " one hundred per cent. efficient sleep," and similar subjects. It is valuable, for it contains ideas which are still new in the West, although they have been taught for thousands of years under other forms in the East. But the first two chapters are so loosely constructed_and dull that we fear many readers will close the book bcfore reaching the practical suggestions Mr. Eeman has to Offer. *Moreover, we are always somewhat doubtful of the general usefulness of direct auto-suggestion and exercises in relaxation unless practised under an experienced teacher, owing to the well-known danger of " reverse sugges- tion." Yet the author's analysis of the causes of con- traction "—both mental and physical—is sound and useful. Anyone who can carry out his advice while avoiding the whirlpools that beset the navigator-on the seas of -the Uncon- seicrus will Certainly tienefit by the exercises euggestecthere.
