CniLDEENTTE. 519 Werther obtained crystalline grains having the form and composition of torberite by boiling iir + # 2 p 4- six with a solu tion of basic acetate of copper. 351. AITTHNITE.—Uranite (in part) ; Phillips, Beudant. Pyramidaler Eucblor-Malachit; Mohs, TJranit; Hausmann, Haidinger. Pyramidal. The forms and angles are supposed to be the same as those of torberite. Cleavage, e, very perfect. Eracture not observable. Trans parent... translucent. Lustre, pearly on c, vitreous inclining to adamantine on the other faces. Lemon-yellow, sulphur-yellow, siskin-green. Streak sulphur-yellow. Sectile. 11 = ro...2 - o. G = 3-0.. .3-2. In the matrass yields water. Before the blowpipe on char coal melts into a black globule. With borax in the outer flame forms a yellow glass, in the inner flame a green glass. The solution in nitric acid is yellow, in ammonia colourless.
