THE 



American Science Series 



FOR HIGH SCHOOLS AND COLLEGES. 



The principal objects of the series are to supply the lack — in some subjects 

 very great — of authoritative books whose principles are, so far as practicable, 

 illustrated by familiar American facts, and also to supply the other iack that 

 the advance of Science perennially creates, of text-books which at least do not 

 contradict the latest generalizations. The books of this series systematically 

 outline the field of Science, as the term is usually employed with reference to 

 general education. The scheme includes an Advanced Course, a Briefer Course, 

 and an Elementary Course. The books arranged for in the Advance Coitrse 

 are as follows. Those with the prices affixed have been published.
