This book, the remarkable work of Dr. Yves Delate, is 

 addressed to philosophers and to students of scientific 

 matters as well as to naturalists and medical men. The 

 author has divided his work into four principal parts. The 

 first part, entitled The Facts, is subdivided into three 

 books: The Cell, the Individual, the Race. The second 

 part treats of Particular Theories. In the third part are 

 exhibited the General Theories of all the French and 

 foreig-n authors who have treated these questions: Buffon, 

 Bechamp, Herbert Spencer, Haacke, Dolbear, Erlsberg-, 

 Hackel, His, Cope, Orr, Mantia, Hanstein, Berthold, 

 Chevreul, Geddes, Tohmpson, Gautier, Danilevsky, H. 

 Fol, Mag-g-i, Altmann, Wiesner, Weismann, Charles Darwin, 

 Maupertuis, Erasmus Darwin, Galton, Jager, Brooks, 

 Gaule, Platt-Ball, Hallez, Nag-eli, Kolliker, H. de Vries, O. 

 Hertwig, Descartes, Roux. Then in the fourth part, after 

 a comprehensive glance over the g"eneral current of ideas, 

 we have, under the title of Theories of Existing Causes, 

 an exposition of the author's ideas on these important sub, 

 jects, which are now the questions of the hour.
