THE AMERICAN SCIENCE SERIES. 
The principal objects of the series are to supply the lack — ir, 
some subjects very great — of authoritative books whose princi- 
ples are, so far as practicable, illustrated by faruiliar Americari 
facts, and also to supply the other lack that the advance of Sci- 
ence perennially creates, of text-books which at least do not 
contradict the latest generalizations. The scheme systematic 
cally outlines the field of Science, as the term is usually em- 
ployed with reference to general education, and includes 
Advanced Courses for maturer college students, Briefer 
Courses for beginners in school or college, and Elementary 
Courses for the youngest classes. The Briefer Courses are not 
mere abridgments of the larger works, but, with perhaps a 
single exception, are much less technical in style and more 
elementary in method. While somewhat narrower in range 
of topics, they give equal emphasis to controlling principles. 
The following books in this series are already published • 
THE HUMAN BODY. By H. Newell Martin, Professor in 
the Johns Hopkins University. 
Advanced Course. 8vo. 655 pp. 
Designed to impart the kind and amount of knowledge every 
educated person should possess of the structure and activities 
and the conditions of healthy working of the human body. 
While intelligible to the general reader, it is accurate and suffi- 
ciently minute in details to meet the requirements of students 
who are not making human anatomy and physiology subjects of 
special advanced study. The regular editions of the book contain 
an appendix on Reproduction and Development, Copies withotU 
this will be sent when specially ordered. 
From the Chicago Tribune: ** The reader who follows him through 
to the end of the book will be better informed on the subject of 
modern physiology in its general features than most of the medical 
practitioners who rest on the knowledge gained in comparatively an- 
tiquated text books, and will, if possessed of average good judgment 
and powers of discrimination, not be in any way confused by state* 
cuents of dubious questions or conilictin^ views."
