It is some years since the first part of Graham's Elements of 

 Chemistry was republished in America, and it is with great pleasure 

 that we have now to notice the appearance of the complete work as 

 issued in very creditable form by Lea and Blanchard, under the editor- 

 ship of Dr. Bridges, who, although making some valuable additions 

 to the first part of the treatise, does not seem to have added anything

 the great completeness of the original work and by the short period 

 which elapsed between its appearance in England and its re-issue in 

 America. 



The present work is issued under the title of " Elements of Inor- 

 ganic Chemistry," and there does not seem much probability of the 

 organic part being ever published. But from the excellence of the 

 portion before us it must be a matter of regret that Mr. Graham should 

 not be induced to devote his attention to that department also. 



All chemists must, however, be deeply grateful to the author for the 

 excellent manual with which he has furnished them, for we have no 

 hesitation in stating, that there is no work in the English language

 we are inclined to give the preference to the work of the British
