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. Illustrated with upwards of 600 wood-cuts. Thick 8vo, 



cloth, including three Appendixes complete to 1882 $10.00 



This work contains full descriptions, physical, chemical and geographical, of 

 all 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. It also 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 

 fullness 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, prepared 

 by Prof. G J. Brush, and the second and third by Mr. E. S. Dana, bringing the 

 subject down, as regards new species, and new determinations of the old, to the 

 date of publication, in 1882.

 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 a few 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 more 

 convenient for use, and contain, besides, a large amount of additional matter in 

 regard to old, as well as new, mineral species.
