Remsen’s Inorganic Chemistry. Apvancep Course. 
By IRA REMSEN, Professor in the Johns Hopkins University. xxii + 827 
pp. 8vo. 
A manual for higher courses. The material is arranged 
according to the Periodic system. The significant relations 
existing between different reactions and different compounds 
are constantly indicated. The dynamical aspect of the science 
and the constitution of compounds are carefully treated. 
Remsen’s Introduction to the Study of Chemistry. 
BRIEFER COURSE. xix+435 pp. 12m0. Third and enlarged edition. 
This book represents. the elementary course in general 
chemistry in the Johns Hopkins University. The main 
principles of the science are developed in the study of a 
carefully planned series of experiments employing at first 
only the commoner gases. After the fundamental laws, and 
as an explanation of them, the theoretical aspects of the 
subject are presented. The elements and their principal 
compounds are then treated in groups, arranged upon the 
Periodic scheme. Both in the discussion and in the experi- 
ments, so far as practicable, questions are made to do duty 
for direct statements. One chapter is devoted to an intro- 
duction to qualitative analysis and two to organic chemistry. 
Remsen’s Elements of Chemistry. E.ementary 
CouRSE. x-+272 pp. 12mo. 
™Ipon the same plan as the foregoing book, but materially 
simpler. It utilizes the facts of every-day experience to show 
what chemistry is and how things are studied chemically, and 
offers a rational course of lessons in which the endeavor is to 
help the pupil to think as well as to see. 
Remsen’s Laboratory Manual. xii+196 pp. 12mo. 
Intended for the “Elements,” but can be used with the 
“Introduction.” There are blank pages for students’ notes.
