Bmericau Science Series 



The two principal objects of the series are to supply author- 

 itative books whose principles are, so far as practicable, illus- 

 trated by American facts, and also to supply the lack that 

 the advance of science perennially creates, of text-books which 

 at least do not contradict the latest generalizations.
