CORSIB 161 COBBUPT PRACTICES granite of various colors, are found. The department is divided into the three arron(}issements of Tulle, Brive, and Ussel. Tulle is the chief town. CORRIB, LOUGH, a lake of the counties Galway and Mayo, the second largest in Ireland. Lying only 30 feet above sea-level, it is of vei'y irregular shape, 25 miles long from N. W. to S. E., and 1 to 6 broad, with an area of 68 square miles. From its S. end, 4 miles N. of Galway, it discharges its surplus waters by Galway river into Galway bay. It receives the waters of Lough Mask, at its N. end, through the Pigeon Hole and other caves, as well as those of the Clare and other smaller rivers. It contains many islets, and to the W. are mountains 3,000 feet high, while near it are many stone-circles. CORRIENTES (kor-yen'tes), a prov- ince of the Argentine Republic, between the Parana and Uruguay rivers, extend- ing from Entre Rios to Misiones terri- tory, with an area of 33,535 square miles. The surface is generally flat, with numerous lakes and swamps, but has undulating stretches along the Pa- rana and in the E., and is heavily wood- ed in parts. Lake Ibera, a group of lakes and swamps covering some 1,800 square miles, is surrounded with a jungle, in which the taciiara bamboo (30 feet) is conspicuous; and here jaguars and alligators abound. The mean tem- perature (72° F.) is the highest in the republic, and the extremes (44° — 98°) are not so excessive. As in Paraguay, Guarani is the common language, Span- ish being employed only by the official and educated classes. Cattle-raising is the chief occupation; agriculture is very backward. Pop. about 350,000. The capital, Corrientes, is almost hidden among orange-groves, 15 miles below the confluence of the Parana and the Paraguay, and takes its name from seven currents formed by points of rock above the city; vessels of nine feet draught can reach the town at all sea- sons. Steamers from Buenos Aires (832 miles) touch here. Pop. about 30,000. CORRIGAN, MICHAEL AUGUS- TINE, an American clergyman; bom in Newark, N. J., Aug. 13, 1839. He was educated at the Roman Catholic Theo- logical seminaries of St. Mary's and Mount St. Mary's and at the American College in Rome, where he was ordained to the priesthood in 1864. He was made president of Seton Hall College in 1868, Bishop of Newark in 1873; Archbishop of Petra and coadjutor to Cardinal Mc; Closkev in 1880; and Archbishop of New York in 1885. He died in 1902. CORROSIVES, in surgery, substances which eat away whatever part of the body they are applied to; such are gla- cial acetic acid, burned alum, white pre- cipitate of mercury, red precipitate of mercury, butter of antimony, etc. CORRPSIVE SUBLIMATE, also called mercuric chloride, HgCU, bichlo- ride of mercury, perchloride of mercury; prepared by heating mercuric sulphate with dry sodium chloride; the mercuric chloride sublimes as a white transparent crystalline mass, sp. gr., 5.43. It is dis- solvable in about 20 parts of cold water, and very soluble in aloohol and ether. It precipitates albumen, hence white of egg is an antidote. It is very poisonous, and is used to preserve both animal and vegetable substances. It is used in pharmacy as Liquor Hydrargyri Per- chloridi, and as Lotio Hydrargyri Flava when mixed with lime. Corrosive sub- limate is a powerful irritant, and is used externally in skin diseases. It is admin- istered internally in syphilis, usually in conjunction with iodide of potassium. It is also much in use by surgeons in an antiseptic spray and as a cleansing agent for sterilizing their operating instruments. As an antiseptic vrash for wounds or sores its strength is generally used in proportion of one part of the salt to 5,000 of the solvent. CORRUGATED METAL, metal that has been corrugated to give it increased rigidity and power to resist buckling and collapse. The process is merely an application to metallic substances of the old contrivance of "goffering" or "pip- ing," by means of which frills are stiff- ened and kept in shape. The metal to be corrugated is passed between pairs of rollers with ridged surfaces, the ridges of one fitting into the hollows of the other, and the sheets or plates operated on are bent and compressed into the wavy outline of the rolls. Walls and roofs of light and temporary buildings are extensiveljr made of corrugated gal- vanized iron — i. e., sheet-iron first corru- gated and subsequently coated with zinc by dipping the sheets into a bath of the liquid metal. CORRUPT PRACTICES, methods em- ployed in elections to influence the voter or to change the result of the election in an improper manner. The practices al- luded to are bribery, making false elec- tion returns, making false declaration regarding election expenses, and person- ation of voters. The English Parlia- ment led the way in putting a stop to these abuses of democratic elections. As early as 1854 it had passed a law against bribery at election, entitled the Corrupt Practices Prevention Act. In
