ART. XLV. — ELEMENTS OF CHEMISTRY, INCLUDING THE 
APPLICATIONS OF THE SCIENCE IN THE ARTS. With 
Numerous Illustrations. By Thomas Graham, F. R. S., Lond. and 
Ed. Professor of Chemistry in University College, London, &c. 
With Notes and Additions, by Robert Bridges, M. D., Professor 
of General and Pharmaceutic Chemistry in the Philadelphia College 
of Pharmacy, &c. Philadelphia: Lea & Blanchard. 1843. 
The student of Chemistry, in this country, cannot hut be 
gratified by the issue of an American edition of Graham's 
Elements by its enterprising publishers, which places at his 
disposal another excellent exposition of chemical science, 
and one which is at least equal to any other work on the 
same subject in the English language. 
Part first contains the fundamental doctrines of the 
science, and embraces, " under the heads of Combining 
Proportions, Atomic Theory, Doctrine of Volumes, Iso- 
morphism, Isomerism, Constitution of Salts and Chemical 
Affinity," a mass of valuable information. The author's 
views of classification, which have been adopted by Kane, 
are also stated at length in this part of the work. 
Part second contains a description of the non-metallic and 
metallic elements, together with their binary compounds and 
salts. This portion of the work, while it is amply compre- 
hensive in detail for the purposes of a text book, embraces a 
more extended view of those substances of importance in 
the ^arts, as Sulphuric Acid, Iodine, Carbonate of Soda, 
Chloride of Lime, etc.; and of the practice of alkalimetry 
and chlorimetry. 
The author has placed the description of the salts of each 
metal, immediately following that of its binary compounds, 
which presents the whole subject at one view, and facilitates 
reference. 
Part third treats of Organic Chemistry. A condensed 
account of organic analysis, the doctrine of substitutions of
