MINERALOGY. 157 



NEW MINERAL SPECIES. 



The following is a list of the species recently introduced 

 as new into mineralogy. They are arranged, for convenience 

 of reference, in alphabetical order : 



Aglaite. A hydrous silicate from Chesterfield, Mass.; de- 

 scribed by Julien. Related to pihlite (cymatolite of Shepard). 



Amesite. Described by Professor Shepard as occurring 

 with diaspore at Chester, Mass. It is found in hexagonal 

 plates and in foliated masses, having the color and lustre of 

 some green talc. An analysis by M. Pisani, of Paris, shows 

 the mineral to be a hydrous silicate of iron, aluminum, and 

 magnesium. It is remarkable for the low percentage of silica 

 (22 per cent.). 



Anomite. A name given by Tschermak to a portion of 

 the biotite micas, particularly those of Lake Baikal, in the 

 Ural. They are distinguished optically, as explained above, 

 from the others which he embraces under the name of me- 

 roxene. 



Arsenargentite. According to Hannay, an arsenide of sil- 

 ver (Ag 3 As). It occurs in orthorhombic crystals, of acicular 

 form, in a mass of metallic arsenic, associated also with some 

 rose quartz. Locality uncertain perhaps Freiberg. 



Bismutosphazrite. A carbonate of bismuth found at N~eu- 

 stadtel, near Schneeberg, Saxony. It appears in spherical 

 and hemispherical forms with concentric structure. The 

 color varies from yellow to brown and black. The specific 

 gravity is high viz., 7.3. According to Weisbach, who de- 

 scribes the species, it is identical with the original " arsen- 

 ical bismuth" of Werner. 



BovMncjite. A problematical species from Bowling, on the 

 Clyde, in Scotland. It is probably a decomposition prod- 

 uct of the mineral chrysolite. It has a deep-green color, is 

 semi-transparent, and has the hardness and feel of steatite. 

 An analysis of the mineral by Hannay, and another by 

 Young, give very different results, so that no dependence 

 can be placed upon the species. 



Bunsenine; Krennerite. A telluride of c;old from Nao-- 

 yag, in Transylvania, has been called "Bunsenin" by Kren- 

 ner. As the name Bunsenite has already been given to 

 another mineral, Vom Rath has proposed to call the new
