THE AMERICAN NATURE SERIES 



In the hope of doing something toward furnishing a series where the 

 nature-lover can surely find a readable book of high authority, the pub- 

 lishers of the American Science Series have begun the publication of the 

 American Nature Series. It is the intention that in its own way, the new 

 series shall stand on a par with its famous predecessor. 



The primary object of the new series is to answer questions those 



(outside of the domain of philosophy) which the contemplation of Nature 



is constantly arousing in the mind of the unscientific intelligent person. 



But a collateral object will be to give some intelligent notion of the 



causes of things." 



The books will be under the guarantee of American experts, and 

 from the American point of view ; and where material crowds space, pref- 

 erence will be given to American facts over others of not more than equal 

 interest. 



The series will be in six divisions : 



I. CLASSIFICATION OF NATURE 



This division will consist of three sections. 



Section A. A large popular Natural History in several volumes, 

 with the topics treated in due proportion, by authors of unquestioned 

 authority.
