REVIEW. 
collected in the form of tables ; and, under the subject "Ana- 
lysis" we have presented to us a most valuable chart of this 
kind, exhibiting all the more ordinary combinations of each 
of the elementary substances, and furnishing the means of 
determining, from the ascertained amount of any such pro- 
duct, the required amount of the element entering into its 
composition. 
In the department of Mineralogy, we are pleased to find 
that Mr. Booth has bestowed a share of attention due to the 
importance of the subject; illustrating, with tolerable fullness, 
a branch of the science which has been too generally ne- 
glected by our writers of chemical treatises. 
In all the branches, there appears to have been incorpo- 
rated into the work the results of the more recent investiga- 
tions and discoveries, thus making it a complete exposition 
of the present state of chemical science ; so that the student 
who, with a good elementary treatise, shall possess himself 
of the Encyclopedia, may consider himself furnished with the 
grammar and dictionary of this province of knowledge. 
The article on " Electricity," by Prof. M'Culloh, is a very 
complete and able essay on that subject, and, if published 
separately, would form a most interesting and valuable 
pamphlet. 
On the whole, we have formed a high opinion of the value 
of the book, and would recommend all desirous of placing in 
their bookcases a comprehensive survey of chemical science 
for reference, to provide themselves with the " Encyclopedia 
of Chemistry" of Mr. Booth. 
Before closing, we should notice the minor, though by no 
means unimportant, subject of its external appearance. The 
book has been got up in a very neat and substantial library 
style, handsomely illustrated with wood-cuts, together with 
a series of engraved plates at the close of the volume. Its 
general appearance is highly creditable to its enterprising 
publisher, and we have no doubt it will meet with a sale pro- 
portioned to its merits. A. B. T.
