 laxis, and sanitation bearing upon the preservation of public health." —

" 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,

 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. Illus- 

 trated. Second Edition. 



" 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." — Aihenaum. 



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'sj personal sympathies." — Pall Mall Gazette.
