Klein, Dr. Carl. [Swiss Minerals.] N. Jahrb.Keit viii. pp. 851-853. 



The most notewoi-thy are the xenotime and anatase of the Binnenthal. 

 Crystals of anatase of the first, second and third types were observed, 

 and some remarkable crystals resembling those of the fourth type, but 

 having the pyramid JP, instead of |P,combined with ooPoo . E. W. R.

Note on the discovery of anatase, in iron-black acute octahedra, with 



brown tabular crystals of brookite, in cavities of a granite at Wolfshau, 



near Schmiedeberg, in Silesia. F. W. R. 



Knop, A. Ueber Koppit vom Kaiserstuhl. [Koppite.] JS\ Jahrb. 

 Heft i. pp. 66-69. 



Finds that the so-called pyrochlore of the Kaiserstuhl diifers chemi- 

 cally from the true pyrochlore, though resembling it physically. Pro- 

 poses, therefore, to distinguish the Kaiserstuhl mineral as a distinct 

 species under the name of Koppite^ after Kopp, of Heidelberg. Koppite 

 contains, R^JS^b.Oj.zzzSllO . 2Nb205, where R=Ce(La, Di), Ca, Na^, K^,

. Ueber Enargit von Man cay an auf Luzon (Manila). [Enargite 



from Luzon.] N. Jahrb. Heft i. pp. 69, 70. 

 Three analyses of enargite from Luzon, where it is used as a copper- 

 ore. Hitherto the mineral has been found only in America. The Luzon 

 mineral agrees in chemical composition with the American specimens 

 previously analyzed. F. \V. E..

 Analysis of a mineral from S. iCarie aux Mines in Alsace, which 

 agrees in composition with the pyrosclerite of Elba. 



. Ueber eine mikrochemische Reaction auf die Glieder der 



Hauynfamilie. [Micro-chemical Reaction of Hauyne Minerals.] 



N. Jahrb, Heft i. pp. 74-76. 



Describes a new reaction by which hauyne, sodalite, imd nosean may 



be distinguished from other minerals. The section of rock containing 



any mineral of the hauyne group is removed from the slide by warm 



alcohol, and transferred to a platinum crucible containing a little 



sulphur. AVheu heated the sulphur sublimes, and the hauyne then 



appears of a beautiful blue colour. The smallest particle can bo thus 



detected. F. W. R.
