or abridgment of any larger work of an European author, (as most 

 American text-books of this sort are,) but the offspring of a mind well 

 imbued with the science, and capable of presenting it in a forcible and 

 attractive style. No experimental details or figures of apparatus are 

 given, and it is evidently intended by the author that these must be 

 supplied by the oral instructions of the teacher, who has access for the 

 purpose to more extended works. The separation of chemical phi- 

 losophy from chemical manipulation seems to be the leading feature of 

 Mr. Smith's creditable work.
