A genus of plants, order POLE MON I A CEE, q. v. were supposed to haunt mines, and to manufacture those ores which looked rich to the eye, but were really of little value. Among these were supposed to be the ores of this metal, and hence its name.) ( Chem .) Cobalt is a metal very similar to nickel in its physical and chemical properties. It generally occurs in the same ore as nickel, and the separation of the two metals is a task requiring great patience and expertne . (. is obtained as a metal either by reducing the oxide by hydrogen, or by calcining the oxalate. In the metallic state it closely resembles steel. It fuses with great difficulty, and oxidizes at a high temperature. It remains unaltered in moist air, di olves slowly in sulphuric and hydrochloric acid, but readily in nitric acid. It is reddish-gray in color, and is said to be magnetic. It is obtained principally from two ores Spei cobalt , and Cobalt glance. The compounds of C. are remarkable for their beauty of color. The two colors, zaffre and smalt , are compounds of C. Zaffre is an impure oxide of this metal, made by calcining the crushed ore in a reverberatory furnace. The sulphur and arsenic are thus roasted off, and the impure oxide remaining is ground to an impalpable powder with two or three parts of fine sand. Zaffre is used largely in the manufacture of stained gla , and in the ornamentation of pottery. Smalt is a finely-powdered blue gla colored with cobalt. C. ore is partially roasted, and combined with an equal quantity of carbonate of potash and twice its weight of well ground quartz. The whole is melted in suitable pots in a furnace, silicate of potash being formed, in which the oxide of cobalt melts, the other impurities falling to the bottom. The clear blue gla is ladled out, poured into water, and ground, when cool, into an impalpable powder. Smalt is used by paper-stainers. With oxygen, cobalt forms a protoxide and a sesquioxide. The anhydrous protozide is obtained by calcining the hydrate or carbonate. It is a black powder, which, when heated in the air, changes into an intermediate oxide, CO304Oxide of C. gives to gla a very intense blue, which resists the action of a very high temperature. Di olved in ammonia, it gives a fine red liquid. Fused with potash, a brilliant blue compound is obtained. With magnesia, alumina, and oxide of zinc, it produces, when fused at a high temperature, pink, blue, and green compounds. The last two are used as pigments. The hydrated oxide is a pink precipitate thrown down by adding a solution of potash to the solution of C. salt. Protoxide of C. forms salts with the acids, which are light blue when hydrated, but turn red when the water is driven off by heat. Pro to nitrate of C. is obtained by di olving the oxide or the metal in nitric acid. It crystallizes in small deliquescent crystals containing six equivalents of water. A solution of this salt is often employed as a sympathetic ink, being light blue when cold, but bright red when the water of hydration is driven off by a gentle heat. The sulphate of C. is generally employed as the source of salts of this metal. The sesquioxide of C. is a brownish powder obtained by pa ing chlorine through a dilute solution of potash, in which the protoxide is mechanically suspended. Its salts are at present unknown. Chloride of C. is prepared by di olving the oxide in hydrochloric acid; the pink solution resulting yields, on evaporation, rose-colored octahedra of the hydrated chloride. The other salts of C. are uninteresting. A solution of the nitrate is used in blowpipe analysis. A small quantity of the substance to be examined is to be moistened with the solution, and heated in the blowpipe flame; a pink color indicates magnesia, and a green and blue, zinc and alumina respectively. Fremy has formed some interesting compounds by combining the sesquioxide of C. with 4, 5, and 6 equivalents of ammonia, forming brown, red, and yellow salts. These double bases he names fuscobaltia , roseocobaltia , and luteocobaltia . Thénard's blue is a beautiful pale-blue pigment, consisting of a mixture of phosphate of C. and phosphate of alumina. Equivalent, 58-6; sp. gr. 85; symbol , Co.-Cobalt ores. The principal ores of C. are white cobalt ore, which is the most common; (it contains C. a ociated with arsenic, iron, and sulphur.) gray cobalt ore , containing arsenic, iron, cobalt, and silica; and glance cobalt , which is a double bisulphide of arsenic and C. All the ores of C. contain more or le nickel. Cobalt, in Connecticut , a post-office of Middle sex co. Cobaltic, a. [Fr. cobalt i que .] Pertaining to cobalt, or consisting of it; resembling cobalt.

Early in life, he served as a private in the army, and devoted all his spare hours to self education. In 1792, he went to the U. States, and settled in Philadelphia, where he commenced his literary саreer. In 1800 he returned to England, and, in 1802, brought out his famous Weekly Political Register , which for 33 years became the leading journal of advanced Radicalism. In 1810, he was prosecuted for a libel on the govt., sentenced to imprisonment, and to pay a fine of $5,000. In 1832, he was returned to the British House of Commons, and died in 1835. Among C.'s best-known his country was the succe ful negotiation of the Treaty of Commerce with France. D. in London, 1865. Cob/den Club, named in honor of R.
