mines of Nischne Tagilsk, in the Urals.* It occurs in small dull 

 black rods, and contains in a hydrated form the protoxides of copper, 

 manganese, and cobalt, with the peroxides of iron and manganese. 

 In •writing the name of this species we have followed the author's 

 mode of orthography, but the etymology of the word clearly de- 

 mands the form Bkdbdionite (pafihlov, diminutive of pafiSos, a 

 rod). 



Hermann publishes the results of his examination of the Eussian 

 mineral Lawrowite,^ which tend to show that it is really a diop- 

 side, coloured bright green by the presence of 4'2 per cent, of 

 hypovanadate of Hme. Accompanying this mineral, he finds a new 

 species of analogous composition, but containing much more vana- 

 dium. This species, which he proposes to name Vanadiolite, may 

 be regarded as formed of three molecules of augite associated with 

 one of hypovanadate of lime. The same author describes, under 

 the term Pliospliorchromite, a Eussian mineral containing chromate 

 of lead and phosphate of copper. 



A new British locality is announced for the beautiful mineral 

 avanturine-quartz.\ Mr. Traill is said to have found it in Orkney, 

 on the S. and S.W. shores of Inganess Bay. 



According to the ' Brighton Herald,' a large deposit of the sub- 

 sulphate of alumina, called Websterite, has been recently found hi 

 Brighton during certain excavations for deep drainage. 



Professor Streng's recently-published ' Mineralogical Notices ' § 

 describe the prehnite of Harzburg, and certain pseudomorphs of 

 calcite and asbestos, after apophyllite, also from Harzburg. 



The attention of the crystallographer may be directed to Dr. 

 Werner's paper " On the Theory of the Hexagonal System ; " || to 

 Dr. Klein's ' Note on some Forms of Galena ; ' IF and to Herr Groth's 

 ' Dissertation on the Topaz of certain Tin-ore Deposits, especially 

 those of Altenberg and Schlaggenwald, in Bohemia.' **

Mining. 



In our Chronicles for July we noticed the proposed amalgamation 

 of the Mines Regulation Bill and the Metalliferous Mines Bill, re- 

 marking on the unfortunate character of this attempt to legislate by 

 one Act for two dangerous industries, differing in all their essential
