Extract

Bolivian minerals have been sent tbr examination and preservation in the British Museum oolleetiml at various times since 1894 by my old school-fellow Mr. Malcolm Robmts, A.R.S.M., now General ganager of the Compagnie Aramayo de Mines en Bolivie. Several of these have been described in the pages of this magazine (see vol. 14, p. 309). Although he has industriously collected Bolivian minerals for over thirty years he is only now rewarded by the discovery of a species new to science. The material which he has been good enough to entrust to me for description was recognized by him as being probably something new, and this was confirmed by a chemical analysis made by Mr. T. Burns MeGhie in the assay office at Quechisla in Bolivia.
