In his remarks upon the results announced in the above table, 
Dr. Ure has added much valuable information, but they are 
too extended for our entire insertion, and too connected to admit 
of abridgment. His candid discussion of the application of 
the atomic doctrine will, we trust, furnish an example of cau- 
tion to some of his contemporaries who have shewn themselves 
more inclined to theory than experiment. Upon the very diffi- 
cult subject of ferro-prussic acid, Dr. Ure has still left ws in 
doubt, we mean as to its nature. We shall, however, conclude 
our extracts with his remarks upon that tantalizing compound.
