 Corrections and Additions. Crown 8vo. 8s. 6d. 



Dr. Hooker, in his address to the British Association, spoke thus 

 of the author: "Of Mr. IVallace and his many contributions 

 to philosophical biology it is not easy to speak without enthu- 

 siasm; for, putting aside their great merits, he, throughout his 

 writings, with a modesty as rare as I believe it to be uncon- 

 scious y forgets his own unquestioned claim to the honour of 

 having originated independently of Mr. Darwin, the theories 

 which he so ably defends." The Saturday Review says : "He 

 has combined an abundance of fresh and original facts with a 

 liveliness and sagacity of reasoning which are not often displayed 

 so effectively on so small a scale?'

 with a study of the Relations of Living and Extinct Faunas as 

 Elucidating the Past Changes of the Earth's Surface. 2 vols. 8vo. 

 with Maps, and numerous Illustrations by Zwecker, 42^. 



The Times says: '''Altogether it is a wonderful and fascinating 

 story, whatever objections may be taken to theories founded upon 

 it. Mr. Wallace has not attempted to add to its interest by any 

 adornments of style ; he has given a simple and clear statement of 

 intrinsically interesting facts, and what he considers to be legiti- 

 mate inductions from them. Natttralists ought to be grateful to 

 him for having undertaken so toilsome a task. The work, indeed, 

 is a credit to all concerned the author, the publishers, the artist 

 unfortunately now no more of the attractive illustrations last 

 but by no means least^ Mr. Stanford's map-designer."
