92 Chemical W nba 
“'The foregoing interesting extracts from the new edition of Dr, 
Henry’s chemistry are sufficient. ‘T’o enter into an analysis of such 
a well known standard work as this, proceeding -from the pen of one 
who ranks among the most eminent chemical philosophers of the day, 
would indeed be a superfluous task. e remember many years ago, 
in a very different chemical era to the present, when the first edition 
of this work appeared under the unpretendiag form of a duodecimo 
volume, intended as a manual for the experimental student. From 
this time, Dr. Henry has been an unremitting laborer in the field of 
science, and as his work in its successive editions has kept a regular 
pace with the advances of chemical knowledge, to which he has him- 
self been so distinguished a contributor, the eleventh edition now ap- 
pears before the public in a very enlarged and ample form, containing 
a store of information, the selection and arrangement of which can- 
not be too highly rated. In short, Dr. Henry is to be esteemed as an 
author, who has always been an industrious collector of facts, and an 
accurate reasoner; avoiding premature speculations, and strenuous 
for the rigid canons of inductive philosophy. For this reason, his 
volumes may be recommended as among the most useful and the 
safest which can be entrusted to the hands of the student.” 
At the moment that this sheet is passing through the press, we 
learn that Mr. Desilver, of Philadelphia, has just published an Amer- 
ican edition of Dr. Henry’s eleventh. He has conferred on the sci- 
entific public of this country an obligation, which we have no doubt 
bo be fully appreciated. 
6. Murray’s Evements.—This excellent work, in two thick oc- 
tavo volumes, was digested by the late Dr. John Murray from his 
large system in four volumes. It is impossible for one who was ac- 
customed to listen to Dr. Murray’s living eloquence, to’ look into his 
works, without seeing the image of his luminous, philosophical mind. 
In his lectures,* his scientific style flowed like a deep river, cleat, 
powerful and serene. His Elements of chemistry are among the 
first of the philosophical treatises of this day and are particularly 
adapted to the diligent perusal of the student, who, having attended 
courses of experimental lectures, is prepared to follow a connected 
train of facts and reasoning, digested in a lucid and attractive form, 
and presenting many original philosophical views. 
The present edition, the sixth, is ably sustained by Dr. Murray’s 
son, in the spirit of bis father, and all his pupils and other admirers 
will be happy to find his reputation in such good keeping.
