In describing the crystals on this specimen I may use the words of Count Bournon, who, after speaking of the elongated octaedron of the former table, says, “The angles of 96° are replaced by a plane which is equally inclined on the adjacent sides, and is frequently very broad. Then the tetraëdral prism is changed into a flat hexaëdral prism having two angles of 84°, and the others of 138°.” The Count never saw the angles of 84° replaced. “The average, specific gravity of this Arseniate of Copper taken on five pure pieces was 4.280.”
