XXII. THE GERM-PLASM: A THEORY OF HEREDITY. By August Weismann, Professor in the University of Freiburg-in-Breisgau. With 24 Illustrations.

“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.

“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.

“Altogether we must congratulate Mr. Ellis upon having produced a book which, apart from its high scientific claims, will, by its straightforward simplicity upon points of delicacy, appeal strongly to all those readers outside purely scientific circles who may be curious in these matters.”—Pall Mall Gazette.

“This striking and important volume ... should place Mr. Havelock Ellis in the front rank of scientific thinkers of the time.”—Westminster Review.

XXV. THE EVOLUTION OF MODERN CAPITALISM. By John A. Hobson, M.A.

“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.
