V.—On two new species recently described by Prof. von Lasaulx

Abstract

At the last meeting of the British Association, Dr. A. yon Lasaulx, who has recently been appointed Professor of Mineralogy in Breslau in succession to Professor Websky, exhibited two new minerals which he has described in the Neues Jahrbuch. A brief notice of these minerals may fitly find a place in the Mineralogical Magazine, although the original descriptions are too lengthy to be translated in extenso.
