2 THE AMERICAN SCIENCE SERIES. 



THE HUMAN BW( .Contimted. 



Briefer Course. I2mo. 364 pp. 



Aims to make the study of this branch of Natural Science a 

 source of discipline to the observing and reasoning faculties, 

 and not merely to present a set of facts, useful to know, which 

 the pupil is to learn by heart, like the multiplication-table. 

 With this in view, the author attempts to exhibit, so far as is 

 practicable in an elementary treatise, the ascertained facts of 

 Physiology as illustrations of, or deductions from, the two car- 

 dinal principles by which it, as a department of modern science, 

 is controlled, namely, the doctrine of the " Conservation of 

 Energy" and that of the " Physiological Division of Labor. " To 

 the same end he also gives simple, practical directions to assist 

 the teacher in demonstrating to the class the fundamental facts 

 of the science. The book includes a chapter on the action upon 

 the body of stimulants and narcotics. 



From HENRY SEWALL, Professor of Physiology, University of Michi- 

 gan : " The number of poor books meant to serve the purpose of 

 text-books of physiology for schools is so great that it is well to 

 define clearly the needs of such a work: I. That it shall contain ac- 

 curate statements of fact. 2. That its facts shall not be too numer- 

 ous, but chosen so that the important truths are recognized in their 

 true relations. 3. That the language shall be so lucid as to give no 

 excuse for misunderstanding. 4. That the value of the study as a 

 discipline to the reasoning faculties shall be continually kept in view. 

 I know of no elementary text-book which is the superior, if the 

 equal, of Prof. Martin's, as judged by these conditions."

A very earnest attempt to present the subject so that children 

 may easily understand it, and, whenever possible, to start with 

 familiar facts and gradually to lead up to less obvious ones. 

 The action on the body of stimulants and narcotics is fully treated. 



From W. S. PERRY, Supet intend? nt of Schools, Ann Arbor, Mich.: 

 *" I find in it the same accuracy of statement and scholarly strength 

 that characterize both the larger editions. The large relative space 

 given to hygiene is fully in accord with the latest educational opinion 

 and practice; while the amount of anatomy and physiology comprised 

 in the compact treatment of these divisions is quite enough for the 

 nost practical knowledge of the subject. The handling of alcohol 

 and narcotics is, in my opinion, especially good. The most admira- 

 ble feature of the book is its fine adaptation to the capacity of younger 

 pupils The diction is simple and pure, the style clear and direct, and 

 the manner of presentation bright and attractive "
