C. F. RaMMELSBERG: Handbuch der Mineralchemie. 8vo, pp. 
1039. Leipzig, 1860.—This work is by no means merely a new 
edition of Rammelsberg’s former ‘‘ Handwirterbuch des chem- 
ischen Theils der Mineralogie.” It is entirely rewritten and re- 
ged, and, as its title indicates, it aims to give the complete 
history of the chemical properties of each mineral species. It 
has seventy pages of introductory matter upon the analyses of 
minerals—the calculation of analyses—a discussion on the value 
of analyses—the chemical constitution of minerals, including 
the function of water—heteromorphism, isomorphism, homceo- 
morphism, etc. ‘The whole is arranged according to a conven- 
ient chemical classification. 
Rammelsberg has done more to give precision to our know!l- 
edge of the chemistry of minerals than any other chemist since 
to the mineralogist, the grandest work of the kind ever pub- 
lished—still on careful examination, we are sorry to observe evi- 
dences of haste, if not carelessness, in its preparation. It is to 
be regretted in such a standard book—as this is sure to become 
Erni, and one by Smith & Brush. “The natural inference is, 
that but one analysis was made by each of the two first named, 
and one by Smith & Tetatesad Hach been the case perhaps 
Rammelsberg might have been justified in his remark, “that
