90 SOME NOTES ON BOOKS. 



Students naturally wish to supplement their knowledge of the 

 anatomy and physiology of animals with information about their habits, 

 and for this purpose there are three excellent works, — CasselVs Natural 

 History, edited by P. Martin Duncan (6 vols., Lond. 1882); TTie 

 Standard or Riverside Natural History, edited by J. S. Kingsley (6 vols. , 

 Lond. 1888), and Brehm's Thierleben, of which a new (3rd) edition is 

 at present in progress (10 vols., Leipzig and Vienna.) Those who read 

 German will also find in Carus Sterne's (Ernst Kraiise's) Werden und 

 Vergehen (3rd ed., Berlin 1886), the most successful attempt yet made 

 to combine in one volume, a history of the earth and its inhabitants. 



Those interested in the psychology of animals should begin with the 

 works of G. J. Romanes, Animal Intelligence, and Mental Evolution of 

 Animals, with Sir John Lubbock's Senses of Animals, and with the 

 recently published book on Animal Life and Intelligence, by C. Lloyd 

 Morgan. 



Of introductions to the study of Evolution, there is no better than A. 

 R. Wallace's Darwinistn (Lond. 1889), and the philosophic student 

 should not omit reading P. Geddes's articles Biology and Evolution 

 in Chambers's Encyclopedia. The great work on the history of 

 Zoology is that of J. V. Carus, Gesckichte der Zoologie (Munich, 1872), 

 but a short sketch wil be found in E. Ray Lankester's article Zoology' in 

 the Encyclopedia Britannica. 



A guide both to the more popular and to the more philosophical 

 literature of Zoology will be found in my Study of Animal Life (I^ond. 

 1891.
