Frenzel-s mineral is rather near the bismutosphaerite of Weisbach, which last seems to be distinct from the other minerals; if the loss (see anal.) is not water, it is an anhydrous carbonate. The bismuth carbonate described by Vogl as occurring at Joachimsthal (Min., p. 717, 753 A), since called Waltherite, includes, according to Bertram! (Bull. Soc. Min., iv., 58, 1881) two species, the one brown, the other green, optically unlike. BlSMutoFErrIte.--App. I., p. 3 J II., p. 7. Bjelkite.--See Cosalite, p. 81. Blackmorite See Opal, p. 86.
