ANNALS OF PHILOSOPHY. OCTOBER, 1824. ARTICLE I. On a new Mineral Substance. By Mr. A. Lévy, MA. of the University of Paris. (To the Editors of the Annals of Philosophy.) GENTLEMEN, Newman-street, Oxford-street, Sept. 17, 1814. MR. HEULAND had put aside a long time since a specimen of Mr. Turner's collection, from the Bank mines, in the government of Ecatherineburgh, in Siberia, considering the small emerald green transparent crystals which are upon it as differing from any described substance. Upon detaching and measuring some of them, I have ascertained that their form was incompatible with those of the arseniates and green carbonate of copper, with which their external characters bear some resemblance, and I am led, therefore, to consider them as belonging to a new mineral species, to which Mr. Heuland proposes to give the name of Brochantite, in honour of a mineralogist as well known here as in his own country. The appearance of the crystals is that of thin rectangular tables, bevelled on the edges with the angles truncated, such as is represented by fig. 7 (Pl. XXXII). Their colours are emerald green, they are transparent, and their hardness is about the same as that of green carbonate of copper. The planes M are blackish and dull; all the others are brilliant and fit for measurement by the reflective goniometer. I have not been able on the very minute crystals I have examined to ascertain the directions of the planes of cleavage, and I have, therefore, assumed as the primitive a right rhombic prism, fig. 6, the lateral planes of which correspond, I believe, with the planes marked M, fig. 7. The planes e1 and a1 are then the results, the first of a decrement by four rows on the angles e of the base of the primitive; the other of a decrement by one row on the angle a. The angles I have New Series, VOL. VIII. R |
