THE AMERICAN SCIENCE SERIES. 



The principal objects of the series are to supply the lack in 

 some subjects very great of authoritative books whose princi- 

 ples are, so far as practicable, illustrated by familiar American 

 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 systemati- 

 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 

 Cor USES 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. Large I2mo. Pp. 655. $2 75. 



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 without 

 tht< 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 

 ir.odern 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- 

 ments of dubious questions or conflicting views."
