Myth and Science.

By Tito Vignoli. 12mo, cloth, price, $1.50.

"His book is ingenious; ... his theory of how science gradually differentiated from and conquered myth is extremely well wrought out, and is probably in essentials correct."—Saturday Review.

"The book is a strong one, and far more interesting to the general reader than its title would indicate. The learning, the acuteness, the strong reasoning power, and the scientific spirit of the author, command admiration."—New York Christian Advocate.

"An attempt made, with much ability and no small measure of success, to trace the origin and development of the myth. The author has pursued his inquiry with much patience and ingenuity, and has produced a very readable and luminous treatise."—Philadelphia North American.

Man before Metals.

By N. Joly, Professor at the Science Faculty of Toulouse; Correspondent of the Institute. With 148 Illustrations. 12mo, cloth, $1.75.

"The discussion of man's origin and early history, by Professor De Quatrefages, formed one of the most useful volumes in the 'International Scientific Series,' and the same collection is now further enriched by a popular treatise on paleontology, by M. N. Joly, Professor in the University of Toulouse. The title of the book, 'Man before Metals,' indicates the limitations of the writer's theme. His object is to bring together the numerous proofs, collected by modern research, of the great age of the human race, and to show us what man was, in respect of customs, industries, and moral or religious ideas, before the use of metals was known to him."—New York Sun.

"An interesting, not to say fascinating volume."— New York Churchman.
