a river of South America, rises in Venezuela, flows first N., then E. through British Guiana, and joins the Mazaruni just above the confluence of the latter with the Essequibo. It has numerous rapids and falls; the lowest is at 59° 3′ W., about 30 miles above the mouth of the river.

an inland city of Peru, capital of a department of same name (area, 156,270 square miles; pop. about ), 500,000 and formerly capital of the empire of the Incas, at the foot of some hills, 11,380 feet above the level of the sea, about 400 miles E. S. E of Lima. According to tradition, this town was founded in 1043, by Manco Capac, the first Inca of Peru. The grandeur and magnificence of the edifices, es, of its fortress, and of the Temple of the Sun, struck the Spaniards with astonishment in 1534, when the city was taken by Francis Pizarro. On the hill toward the north are yet seen the ruins of a fortress built by the Incas. Pop. about 15,000. CYANAMID. NC.NH2, formed by the action of ammonia on cyanogen chloride. The name is also applied to the compound calcium, Cyanamid NC.NCa, an important product formed in the fixation of atmospheric nitrogen by the socalled "cyanamid process." Calcium carbide is first produced by heating carbon and calcium at high temperatures in an electric furnace, and this compound is then heated under pressure with nitrogen obtained from the air. The crude product, known also as Nitrolim, is used as a fertilizer and undergoes decomposition in the soil with the production of cyanamid. The latter is then converted to urea, which is hydrolyzed to ammonium carbonate by organisms in the soil (q. v. NITROGEN).

The head-chief of the Egbo Assembly, a secret council of Old Calabar. D tions of the planets. A wedding ring is, however, most in favour for purposes of this sort. Another way is to suspend the ring within a glass tumbler, or just outside of it so, that the ring on being swung may easily touch the glass. As with table-rapping, a code may then be arranged, the glass being struck once for an affirmative, twice for a negative answer, and so on. Suspended above a sovereign, the ring will indicate the person from whose head hair has been taken, or, if requested, any other member of the company.

Important: Safety Warning This page contains a formula or preparation using substances now known to be dangerously toxic, such as arsenic, mercury, lead, or cyanide compounds. Exposure to these substances can cause severe poisoning, permanent injury, or death. This information has been left in for historical purposes but should not be acted upon. dicyanogen, (CN)2, or (N-C) — (C-N), or Cy2. Obtained by heating silver or mercuric cyanide; also by dry distillation of ammonium oxalate. Cyanogen is a colorless poisonous gas which liquifies at -25°, or under a pressure of four atmospheres at 20°, and at -34° becomes crystalline. It burns with a peach-blossom-colored flame, forming CO2 and nitrogen; water dissolves four volumes, and alcohol 23 volumes of the gas. Cyanogen is very poisonous, and smells like prussic acid. Cyanogen gas passed into strong aqueous hydrochloric acid is converted into oxamide. Cyanogen dissolves in an aqueous solution of potash, forming cyanide and isocyanate of potassium. Cyanogen can be regarded as the nitril of oxalic acid. Dry ammonia gas and cyanogen combine, forming hydrazulmin, C4N6H6. C.N Small quantitie tities of cyanogen are formed during the distillation of coal. Potassium burns in cyanogen gas, forming potassium cyanide. Cyanogen was discovered by Gay- Lussac in 1815.

A curve generated by a point in the plane of a circle, when the circle is rolled along a straight line, keeping always in the same plane. The path through which a pendulum travels, to secure uniformity in the time of its vibration, through arcs different in extent, should be cycloidal.

an invention for measuring and recording the distance traveled by wheeled vehicles, extensively used in cycling. Its most important application is in railroading. The apparatus is connected with the wheels of a car, and by recording the number of revolutions tells on a sheet of paper inside the car the number of miles traveled. It is purely automatic, and in addition, by an attachment of extreme beauty and ingenuity, every inequality in the roadbed of a railroad is detected and located.

A race of men of gigantic stature, supposed to be the sons of Coelus and Terra. They had only one eye, which was in the center of the forehead. According to Hesiod they were three in number, and named Arges, Brontes, and Steropes. Cynossema (Dog's Tomb). A promontory in the Thracian Chersonesus near Madytus, so called because it was supposed to be the tomb of Hecuba , who had been previously changed into a dog. 2026 Editor's Note: Cyclopes appear in multiple distinct mythological traditions: Hesiod describes three divine brothers—Arges, Brontes, and Steropes—who forged Zeus's thunderbolt and Poseidon's trident, while Homer's Odyssey portrays them as uncivilized, cave-dwelling shepherds including Polyphemus. A third group reputedly constructed the Cyclopean walls of Mycenae and Tiryns. (Ed: BR 2026-06-09)
