6 THE AMERICAN SCIENCE SERIES. 



CHEMISTRY. By IRA REMSEN, Professor in the Johns Hop- 

 kins University. 

 Advanced Course. 8vo. 828 pp. 



The general plan of this work will be the same with that of 

 the Briefer Course, already published. But the part in which 

 the members of the different families are treated will be con- 

 siderably enlarged. Some attention will be given to the lines 

 of investigation regarding chemical affinity, dissociation, speed 

 of chemical action, mass action, chemical equilibrium, thermo- 

 chemistry, etc. The periodic law, and the numerous relations 

 which have been traced between the chemical and physical 

 properties of the elements and their positions in the periodic 

 system will be specially emphasized. Reference will also be 

 made to the subject of the chemical constitution of compounds, 

 and the methods used in determining constitution. 



Introduction to the Study of Chemistry. I2mo. 389 pp. 



The one comprehensive truth which the author aims to make 

 clear to the student is the essential nature of chemical action. 

 With this in view, he devotes the first 208 pages of the book to 

 a carefully selected and arranged series of simple experiments, 

 in which are gradually developed the main principles of the sub- 

 ject. His method is purely inductive ; and, wherever experience 

 has shown it to be practicable, the truths are drawn out by 

 pointed questions, rather than fully stated. Next, when the 

 student is in a position to appreciate it, comes a simple account 

 of the theory of the science. The last 150 pages of the book 

 are given to a survey, fully illustrated by experiments, of the 

 leading families of inorganic compounds. 



From ARTHUR W. WRIGHT, Professor in Yale College : The student 

 is not merely made acquainted with the phenomena of chemistry, but 

 is constantly led to reason upon them, to draw conclusions from them 

 and to study their significance with reference to the processes ot 

 chemical action a course which makes the book in a high degree dis- 

 ciplinary as well as instructive. 



From THOS. C. VAN NUYS, Professor of Chemistry in the Indiana 

 University: It seems to me that Remsen's "Introduction to the 

 Study of Chemistry" meets every requirement as a text or class book. 



From C. LES MEES, Prof essor of Chemistry in the Ohio University: 

 I unhesitatingly recommend it as the best work as yet published for 

 the use of beginners in the study. Having used it, I feel justified in 

 saying this much.
