4 Mr. Edward Arnold's List of Scientific Books. 



THE EVOLUTION THEORY. By August Weismann, Professor of 



Zoology in the University of Freiburg-im-Breisgau. Translated by Professor 

 J. Arthur Thomson. With numerous Illustrations and Coloured Plates. 

 Two Vols. Royal 8vo., 32s. net. 



The importance of this work is twofold. In the first place, it sums up the 

 teaching of one of Darwin's greatest successors, who has been for many years a 

 leader in biological progress. As Professor Weismann has from time to time 

 during the last quarter of a century frankly altered some of his positions, this 

 deliberate summing up of his mature conclusions is very valuable. In the second 

 place, as the volumes discuss all the chief problems of organic evolution, they 

 form a reliable guide to the whole subject, and may be regarded as furnishing — 

 what is much needed — a Text-book of Evolution Theory.
