 [QUARTEKLY REVIEW, No. 165.] 



IN giving the titles of these systematic works on Chemistry, 

 to which many others might be added, we must not be 

 understood to intend an analysis of their contents, or even a 

 critical comparison of their merits. Chemical science has 

 become far too vast and complex a subject to be dealt with by 

 any summary in the pages of a Review. It stands apart from 

 and beyond the margin of critical literature. Yet, as we 

 have been accustomed, from time to time, to place before our 

 readers those works which more strikingly illustrate the 

 progress and revolutions of physical knowledge, we would 

 now use the volumes before us as the foundation of a brief 

 sketch of some of the great changes which Chemistry has 

 undergone within the last fifty or sixty years, and notably 

 within the latter half of this period. A general statement of 

 the principles and present methods of the science, and of the 

 more remarkable discoveries to which they have led, is all we 

 can undertake to give ; with no other details than such as 

 are needful for illustration. 



Even this limited outline is not without its difficulties, 

 seeing the magnitude and variety of the changes that have
