XXIII. MAN AND WOMAN. By Havelock Ellis. Illustrated. Second Edition. 6s.
“Mr. Havelock Ellis belongs, in some measure, to the continental school of anthropologists; but while equally methodical in the collection of facts, he is far more cautious in the invention of theories, and he has the further distinction of being not only able to think, but able to write. His book is a sane and impartial consideration, from a psychological and anthropological point of view, of a subject which is certainly of primary interest.”—Athenæum.
