SIDNEY HARTLAND. “Mr. Hartland’s book will win the sympathy of all earnest students, both by the knowledge it displays, and by a thorough love and appreciation of his subject, which is evident throughout.”--_Spectator._ XII. PRIMITIVE FOLK. By ELIE RECLUS. “An attractive and useful introduction to the study of some aspects of ethnography.”--_Nature._ “For an introduction to the study of the questions of property, marriage, government, religion,--in a word, to the evolution of society,--this little volume will be found most convenient.”--_Scottish Leader._ XIII. THE EVOLUTION OF MARRIAGE. By Professor LETOURNEAU. “Among the distinguished French students of sociology, Professor Letourneau has long stood in the first rank. He approaches the great study of man free from bias and shy of generalisations. To collect, scrutinise, and appraise facts is his chief business. In the volume before us he shows these qualities in an admirable degree.... At the close of his attractive pages he ventures to forecast the future of the institution of marriage.”--_Science._ XIV. BACTERIA AND THEIR PRODUCTS. By Dr. G. SIMS WOODHEAD. Illustrated. “An excellent summary of the present state of knowledge of the subject.”--_Lancet._ XV. EDUCATION AND HEREDITY. By J. M. GUYAU. “It is at once a treatise on sociology, ethics, and pædagogics. It is doubtful whether among all the ardent evolutionists who have had their say on the moral and the educational question any one has carried forward the new doctrine so boldly to its extreme logical consequence.”--Professor SULLY in _Mind_. XVI. THE MAN OF GENIUS. By Prof. LOMBROSO. Illustrated. “By far the most comprehensive and fascinating collection of facts and generalizations concerning genius which has yet been brought together.”--_Journal of Mental Science._ XVII.

PROPERTY: ITS ORIGIN AND DEVELOPMENT. By CH. LETOURNEAU, General Secretary to the Anthropological Society, Paris, and Professor in the School of Anthropology, Paris.
