A SYSTEM OF MINERALOGY—DESCRIPTIVE MINERALOGY, 
comprising the most recent discoveries. By James Dwight Dana, Prof. 
of Geology and Mineralogy, Yale College, aided by Prof. George Jarvis 
Brush, of Sheffield Scientific School. Fifth edition, re-written and en- 
larged. Jllustrated with upwards of 600 wood-cuts. Thick 8vo, 
This work contains full descriptions, physical, chemical and geographical, of 
ail known minerals up to the time of publication. Besides giving the composition 
of minerals at length, it includes all the analyses that had been made from the first 
beginning of analytical chemistry, along with references to their authors, and the 
works or memoirs in which they appeared. Italso gives, under each species, de- 
tailed statements of the blowpipe characters of each, prepared by Prof. Brush, 
extended notices of Foreign, as well as American localities—the latter with special - 
fuliness as regards modes of occurence and associated minerals,—and a complete 
historical account of the names of minerals and their varieties, and of all syno- 
nyms. 
The volume, as now issued, includes three appendixes: the first and second 
prepared by Prof. G. J. Brush, and the third by Mr. H. 8. Dana, bringing the sub- 
ject down, as regards new species, and new determinations of the ola, to the date 
of publication of the last, in the latter part of 187).

MANUAL OF DETERMINATIVE MINERALOGY, with an intro- 
duction on BLOWPIPE ANALYSIS. By George J. Brush, Professor of 
Mineralogy in the Sheffield Scientific School of Yale College. Third 
edition, revised and corrected, with NEw NoTATION. 8vo, cloth, $3.50 
The method of instruction adopted in this work is first to give the student a 
preliminary knowledge of the use of the blowpipe and other apparatus employed 
in the determination of minerals. It includes a systematic course of Qualitative 
Blowpipe Analysis, with tables of reactions of the metals, metallic oxides, and 
earths with and without fluxes, concluding with an alphabetical list of elements 
and compounds, with their characteristic blowpipe and other reactions. This is 
followed by tables for the determination of mineral species, which are so arranged 
that by means of a few simple experiments before the blowpipe and in the wet 
way, the mineral is quickly limited to a group of afew species; among the mem- 
bers of this group the mineral is distinguished by other trials, and when from these 
various experiments the mineral species is finally decided upon, the conclusion is 
confirmed or corrected by reference to the chemical composition, crystalline form 
and other physical characteristics given in the tables. 
An acquaintance with the use of the blowpipe, such as is gained by the study of 
the introductory pages, and with the manner of performing the simplest opera- 
tions of solution and precipitation, is all that is necessary in making the requisite 
trials. 
These determinative tables, while founded upon the tenth edition of Professor 
Von Kobell’s well-known work, are arranged in an entirely new form, much mcre 
convenient for use, and contain, besides, a large amount on additional matter in 
regard to old, as well as new, mineral species.
