"There has been no work published since Darwin's own books which has so thoroughly handled the matter treated by him, or has done so much to place in order and clearness the immense complexity of the factors of heredity, or, lastly, has brought to light so many new facts and considerations bearing on the subject."—British Medical Journal.
XXIII. INDUSTRIES OF ANIMALS. By F. Houssay. With numerous Illustrations. 3s. 6d.
"His accuracy is undoubted, yet his facts out-marvel all romance. These facts are here made use of as materials wherewith to form the mighty fabric of evolution."—Manchester Guardian.
XXIV. 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.
XXV. THE EVOLUTION OF MODERN CAPITALISM. By John A. Hobson, M.A. 3s. 6d.
"Every page affords evidence of wide and minute study, a weighing of facts as conscientious as it is acute, a keen sense of the importance of certain points as to which economists of all schools have hitherto been confused and careless, and an impartiality generally so great as to give no indication of his [Mr. Hobson's] personal sympathies."—Pall Mall Gazette.
XXVI. APPARITIONS AND THOUGHT-TRANSFERENCE. By Frank Podmore, M.A. 3s. 6d.
