THE STUDY OF ANIMAL LIFE 



By J. ARTHUR THOMSON, M.A., F.R.S.E., University 

 of Edinburgh. i2mo, Illustrated, $1.50 net. 



An original and comprehensive account of all animal life, save 

 man. Such topics as the wealth of life on the earth, its distri- 

 bution, the struggle for existence, the social and domestic life of 

 animals, instinct, structure, heredity, influence of habit and sur- 

 roundings, etc., are thoroughly discussed, though in a bright and 

 interesting way, and with the fact constantly in mind that the 

 book is a manual and not a cyclopaedia or a special treatise. 



" I have read it with great delight. It is an admirable work, giving a true 

 view of the existing state and tendencies of zoology ; and it possesses the rare 

 merit of being an elementary work, written from the standpoint of the most 

 advanced thought, and in a manner to be understood bv the beginning stu- 

 dent." J. H. COMSTOCK, Professor of Entomology in Cornhill University, 

 and in Leland Stanford Junior Uniz'ersity. 



" An interesting and stimulating book, especially so for teachers. The 

 style is clear and attractive, and the illustrations excellent. The views taken 

 as to evolution and heredity are sound and broad." A. S. PACKARD, Professor 

 of Zoology, Brown University.
