Descriptions of Two new Minerals. By Mr. A. Levy, MA. FGS^ (To the Editors of the Annals of Philosophy.) GENTLEMEN, Among many very interesting specimens, and several unde- scribed substances, which were in the collection of Marquis de Dree, and which Mr. Heuland, who lately bought it, has added to his own private collection, are the two of which 1 now send the descriptions for insertion in the Annals of Philosophy, and which belong, I believe, to two new species. For one of them I propose the name of Beudantite, in honour of Mr. Beudant, and for the other, at the suggestion of Mr. Heuland, the name of Kdnigine, in compliment to Mr. Konig, of the British Museum. K'dnigine. The characters which distinguish this substance from any hitherto described, were ascertained before the arrival of Mar- quis de Dree's collection into this country upon a specimen now in the possession of the Dowager Countess of Aylesford. The specimen which subsequently was found to belong to the same species had the following ticket {cuivre muriate et phosphate). In both cases the mineral occurs in small crystals, emerald-green and blackish-green, translucent, and of either of the forms represented by figs. 1, 2, 3. These crystals cleave only and very easily in a direction parallel to the plane P of the drawing; the face obtained by cleavage is very brilliant, and at right angles to the lateral planes m. These lateral planes are generally dull Fig. m m 'V Fig. 3. 1. ? 1 i-H V h i m i^ -•"' ^.
