uranophane

[Pref. urano-, 2., and Greek phaino=to cause to appear.] Min .: An orthorhombic mineral occurring in ex ceedingly minute crystals on the sides of fi ures in granite at Kupferberg, Silesia. Hardne , 2-5-3; specific gravity, 2-6-2-8; color, honey-yellow. Composition: E entially a hydrated silicate of sesqui oxide of uranium, alumina, and lime. phyllite.] two dorsal fins, ventrals jugu lar, pectorals branched; vil liform teeth in jaws, on vo mer, and palatine bones; a long filament usually pres ent before and below the tongue: gill cover armed. The eyes which are very small, can be raised or depre ed at will. The spe- cies are small, inactive fishes, rarely a foot long, generally lying hidden at the bottom between stones watching for their prey. The filament at attached to the bottom of their mouth, and playing boil, boy; pout, jowl; cat, çell, chorus, Uranoscopus Scaber. chin, bench; go, gem; thin, this; Uranus in the current of water pa ing through the mouth, serves to allure small marine animals within their reach. ür-an-os-co-pỹ, subst. [Pref. urano-, 1., and Gr. skopeo to see, to observe.] Contemplation of the heavenly bodies. ür-a-nō-sō-, pref. [Mod. Lat. uranosus=uranous (q. v.).] thallite.] Min.: A mineral occurring in aggregates of minute crystals or grains as encrustations on uranium ores. Hardne , 2-5-30; color, and streak, siskin green; luster, vitreous, on cleavage faces pearly. Composition: A hydrated carbonate of uranium and Found at Joachimsthal, Bohemia. u-răn-o-thör'-ite, s. [Pref. urano-, 2., and Eng. thorite.] Mineral.: A variety of thorite (q. v.), containing nearly 10 per cent. of sesquioxide of uranium. Found in the Cham plain iron region, New York. u-răn-o-tîl, s. [URANIUM.] Mineral .: An orthorhombic mineral occurring in radiating or stellar groups of acicular crystals. Specific gravity, 3.95; color, lemon-yellow. The mean of analyses gave: Silica, sesquioxide of uranium, 66-75; alumina and sesquioxide of iron, 0-51; lime, 5-27; phosphoric acid, 045; water, 12.67-99-43, which resembles the composition of uranophane (q. v.).
