 here made use of as materials wherewith to form the mighty fabric of evolution."

XXIV. MAN AND WOMAN. By HAVELOCK ELLIS. Illus- 

 trated. Second Edition. 6s. 



"Mr. Havelock Ellis belongs, in some measure, to the continental school of anthro- 

 pologists ; 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 considera- 

 tion, from a psychological and anthropological point of view, of a subject which is 

 certainly of primary interest." Athenaeum.

 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] per- 

 sonal sympathies." Pall Mall Gazette. 



XXVI. APPARITIONS AND THOUGHT-TRANSFERENCE. 



By FRANK PODMORE, M.A. 35. 6d.
