38°10 28°88 0°85 18°26 0°23 0°65 11°42 = 98:39 
This yields the formula H,Ca A1,Si 20193 a possible relation to 
cearpholite is suggested. — Bull. Dept. Geol, Univ. California, vol. 
nm INO. 10. 
Eupipirre.—A silicate of zirconium and sodium from Igaliko, 
Greenland, described by G. Lindstrém, It occurs in fine fibrous 
forms with silky luster ; the color varies from white to yellowish 
white and light brick-colored; hardness about that of quartz; 
specific gravity 2°524 to 2° 594, Analysis gave: 
SiO, ZrO. Na,O KO FeO CaO H0(100°) H.O(ign.) Cl 
59°44 20-48 10-41 0°13 0-14 O17 3:89 5°72 0°15 CuO, TiO. #r=100°53 
The calculated formula is Na,O.ZrO,.65i0,.3H,0.— Geol. For 
Forh., xvi, 330, 1894. 
LossENITE.—A new arsenate from Laurium, Greece. Des- 
cribed by L. Milch. It occurs in small red-brown crystals 
referred to the orthorhombic system and resembling scorodite in 
form. Analysis by Auerbach gave (after deducing gangue) 
As20; SO; Fe.0s PbO H,O (comb.) H.O 
34°33 3°84 35°45 10°91 3°84 12°12 = 100°49 
For this the complex formula 2PbSO,.6(FeOH), As,O,. 27H,O 
is calculated.—Zettschr. Kryst; xxiv, 100, 1894. 
DIExTZEITE.—A name proposed by Osann for the iodate and 
chromate of calcium occurring, as described by Dietze, with the 
calcium iodate, lautarite, at the Pampa del Toro, Chili ’(Zeitschr. 
Kryst., xix, 447, 1891 and Dana, Syst. Min., 1892, p. 1040). 
Osann describes monoclinic crystals. 
Urpanire.—A name proposed by Sjogren for a so-called iron- 
schefferite analyzed by Mauzelius, trom Langban, Sweden. Igel- 
strom later calls it lénmdesite and claims priority on insufficient 
grounds.— Geol. LG6r. Horh., xiv, 251, 1892; Zettschr. Kryst., 
Xxili, 590, 1894. 
MineErvite.—A phosphate of aluminum occurring in seams in 
. a calcium phosphate, a formation in the “Grotte de Minerve” on 
the shores of the river Cesse, Dept. Aude, France. ‘The formula 
POF AO Tenis deduced for it described by A. Gautier.— 
Bull. Soc. Min., xvii, 332, 1894. 
Wxpyerits.—An argentifer ous variety of zinckenite described 
by Stelzner from Oruro, Bolivia. It has been found in massive 
form only. An analysis by P. J. Mann gave: 
8 Sb Pb Ag Cu Fe 
23°10 40°86 24°30 10:25 0°65 0 53=99°69 
This leads to the formula PbS. Sb,S, in which silver replaces 
lead, the ratio for Pb: Ag being about 5 : 2.—Zeitschr. Kryst., 
xxiv, 125, 1894.
