92 Chemical Works. 



"The foregoing interesting extracts from the new edition of Dr. 

 Henry's chemistry are sufficient. To 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. We remember many years ago, 

 in a very different chemical era to die present, when the first edition 

 of this work appeared under the unpretending 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 pubhc 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 

 will be fully appreciated. 



6. Murray's Elements. — 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, clear, 

 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 his father, and all his pupils and other admirers 

 will be happy to find his reputation in such good keeping.
