GENERAL WORKS ON MINERALOGY. 



The additious to the list of miueralogical treatises Lave uot been 

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

 Text-Boole of Descriptive Mineralogy, by Mr. Hilary Bauerman, ot the 

 Eoyal School of Miues in Loudon. It forms a companion volume to the 

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

 noticed in the report for 1882. The present volume is devoted to the 

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

 ways as fully 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, prepared by Brooke and Miller in 1852, 

 a volume to which every working mineralogist now refers almost dailj', 

 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, whicli deserves mention, though of modest propor- 

 tions. Dr. Weisbach has issued a new edition of his i^ynopsis Minera- 

 logica,* which gives a summary of mineral species, arranged according 

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

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

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

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

 length in this part are caledonite and wollastonite, but supplementary 

 notices are also given of monazite, rutile, pachnolite, and xaut hophylite; 

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



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

 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,
