MINERALOGY.

GENERAL, WORKS ON MINERALOGY. 



The additious to the list of mineralogical treatises have not been 

 numerous duriug the past year. Perhaps the most noteworthy is the 

 Text-Book of Descriptive Mineral of))/, by Mr. Hihiry Bauerman, ot the 

 Royal School of Mines in London. It forms a companion volume to the 

 Text-Book of Systematic Mineralogy, published three year ago, and 

 noticed in the report for 18S2. The present volume is devoted to the 

 descriptions of species, which, though necessarily brief and not al- 

 ways as fullj" up to date as might be desired, are on the whole satisfac- 

 tory. It is interesting to note that the figures through the work are 

 for the most part printed from the original blocks used in the revised 

 edition of Phillips's Mineralogy, pre])ared by Brooke and Miller in 1852, 

 a volume to which every working mineralogist now refers almost daily, 

 notwithstanding the fact that it was prepared so many years since. An 

 elementary text-book of mineralogy has been published in Germany by 

 Dr. H, Baumhauer, which deserves mention, though of modest propor- 

 tions. Dr. Weisbach has issued a new edition of his Synopsis Minera- 

 logica,* which gives a summarj' of mineral species, arranged according 

 •to their chemical composition, with notes as to their crystalline form 

 and some other points. xMore important than this last work is the open- 

 ing portion (first 80 pages) of the ninth volume of the 3faterialien zur 

 Mineralogie Russlands, by N. v. Kokscharow. The species treated at 

 length in this part are caledonite and wollastouite, but supi)lementary 

 notices are also given of monazite, rutile, pachnolite, and xanthophylite; 

 the whole work is a monument of careful and accurate labor. 



A large volume (630 pages) has been published, under the editorsliij) 

 of Dr. J. B. Marvin, of the Original Researches in Mineralogy and Chem- 

 istry of the late Dr. J. Lawrence Smith. Dr. Smith was for many years 

 one of the most active contributors to these sciences in the United States,
