SELECT METHODS IN CHEMICAL ANALYSIS (chiefly Inor- 

 ganic). 



By William Crookes, F.R.S., V.P.C.S. With 37 Illustrations. 8vo. 

 797 pages. $8.00. 



PRINCIPLES OF GENERAL ORGANIC CHEMISTRY. 



By Professor E. HjELT, of Helsingfors. Translated from the German by 

 J. Bishop Tingle, Ph.D., Assistant in the Laboratory of the Heriot 

 Watt College, Edinburgh. 8vo. 230 pages. $1.75. 



In this work the fundamental theories of organic chemistry are presented in 

 a clear and concise form, and their application is fully illustrated by examples. 

 The relations between the constitution of compounds and their chemical and 

 physical properties are prominently exhibited. A considerable number of gen- 

 eral reactions are discussed and explained ; in all cases these are classified ac- 

 cording to the results. For instance, reactions involving oxidation are grouped 

 together, and examples are given of the effects of oxidation on different classes 

 of compounds; a lucid account is also given of the special application of par- 

 ticular oxidizing agents. 



MANUAL OF QUALITATIVE ANALYSIS AND LABORA- 

 TORY PRACTICE. 



By T. E. Thorpe, Ph.D., F.R.S.E., Professor of Chemistry in the Ander- 

 sonian University, Glasgow; and M. M. Pattison Muir. With 57 

 Woodcuts. (Text-Books of Science.) i2mo. 262 pages. $1.25.4 



'' We have endeavored to make this book as practical as possible. The 

 methods of analysis are, of course, mainly founded on established and reliable 

 processes. Still, the book will be found to contain a number of novelties, both 

 in the way of shortening the course of systematic testing, and in the recognition 

 of bodies by means of special tests. We have hesitated, however, to adopt new 

 methods unless experience has shown them to be preferable to the older ones. 

 All the experiments described have been repeatedly tested.'' — Author^s Pref- 

 ace. 



INORGANIC CHEMISTRY, THEORETICAL AND PRACTI- 

 CAL : A Manual for Students in Advanced Classes. 



By William Jago, F.C.S., F.I.C. With 78 Woodcuts and a Colored 

 Plate of Spectra. Crown 8vo. 470 pages. $1.50. 



" The arrangement and treatment of the subject is most excellent, and in- 

 cludes the most recent advances and discoveries in the science. The work is 

 worthy the attention and favorable consideration of both teachers and students 

 of chemistry." — Pop2ilar Science News.
