 81 m. N. of Lyons by the Paris-Lyon railway. Pop. (1906) 26,538. It is a well-built town, with fine quays, situated in an extensive plain on the right bank of the Saône at its junction with the Canal du Centre. A handsome stone bridge of the 15th century, decorated in the 18th century with obelisks, connects it with the suburb of St Laurent on an island in the river. The principal building is the church of St Vincent, once the cathedral. It dates mainly from the 12th to the 15th centuries, but the façade is modern and unpleasing. The old bishop’s palace is a building of the 15th century. The church of St Pierre, with two lofty steeples, dates from the late 17th century. Chalon preserves remains of its ancient ramparts and a number of old houses. The administrative buildings are modern. An obelisk was erected in 1730 to commemorate the opening of the canal. There is a statue of J. N. Niepce, a native of the town. Chalon is the seat of a sub-prefect and a court of assizes, and there are tribunals of first instance and commerce, a branch of the Bank of France, a chamber of commerce, communal colleges for boys and girls, a school of drawing, a public library and a museum. Chalon ranks next to Le Creusot among the manufacturing towns of Burgundy; its position at the junction of the Canal du Centre and the Saône, and as a railway centre for Lyons, Paris, Dôle, Lons-le-Saunier and Roanne, brings it a large transit trade. The founding and working of copper and iron is its main industry; the large engineering works of Petit-Creusot, a branch of those of Le Creusot, construct bridges, tug-boats and torpedo-boats; distilleries, glass-works, chemical works, straw-hat manufactories, oil-works, tile-works and sugar refineries also occupy many hands. Wine, grain, iron, leather and timber are among the many products for which the town is an entrepôt. About 2 m. east of Chalon is St Marcel (named after the saint who in the 2nd century preached Christianity at Chalon), which has a church of the 12th century, once belonging to a famous abbey.

Chalon-sur-Saône is identified with the ancient Cabillonum, originally an important town of the Aedui. It was chosen in the 6th century by Gontram, king of Burgundy, as his capital; and it continued till the 10th to pay for its importance by being frequently sacked. The bishopric, founded in the 4th century, was suppressed at the Revolution. In feudal times Chalon was the capital of a countship. In 1237 it was given in exchange for other fiefs in the Jura by Jean le Sage, whose descendants nevertheless retained the title. Hugh IV., duke of Burgundy, the other party to the exchange, gave the citizens a communal charter in 1256. In its modern history the most important event was the resistance offered to a division of the Austrian army in 1814.

 CHALUKYA, the name of an Indian dynasty which ruled in the Deccan from 550 to 750, and again from 973 to 1190. The Chalukyas themselves claimed to be Rajputs from the north who imposed their rule on the Dravidian inhabitants of the Deccan tableland, and there is some evidence for connecting them with the Chapas, a branch of the foreign Gurjaras. The dynasty was founded by a chief named Pulakesin I., who mastered the town of Vatapi (now Badami, in the Bijapur district) about 550. His sons extended their principality east and west; but the founder of the Chalukya greatness was his grandson Pulakesin II., who succeeded in 608 and proceeded to extend his rule at the expense of his neighbours. In 609 he established as his viceroy in Vengi his brother Kubja Vishnuvardhana, who in 615 declared his independence and established the dynasty of Eastern Chalukyas, which lasted till 1070. In 620 Pulakesin defeated (q.v.), the powerful overlord of northern India, and established the Nerbudda as the boundary between the South and North. He also defeated in turn the Chola, Pandya and Kerala kings, and by 630 was beyond dispute the most powerful sovereign in the Deccan. In 642, however, his capital was taken and he himself killed by the Pallava king Narasimhavarman. In 655 the Chalukya power was restored by Pulakesin’s son Vikramaditya I.; but the struggle with the Pallavas continued until, in 740, Vikramaditya II. destroyed the Pallava capital. In 750 Vikramaditya’s son, Kirtivarman Chalukya, was overthrown by the Rashtrakutas.

In 973, Taila or Tailapa II. (d. 995), a scion of the royal Chalukya race, succeeded in overthrowing the Rashtrakuta king Kakka II., and in recovering all the ancient territory of the Chalukyas with the exception of Gujarat. He was the founder of the dynasty known as the Chalukyas of Kalyani. About 1000 a formidable invasion by the Chola king Rajaraja the Great was defeated, and in 1052 Somesvara I., or Ahamavalla (d. 1068), the founder of Kalyani, defeated and slew the Chola Rajadhiraja. The reign of Vikramaditya VI., or Vikramanka, which lasted from 1076 to 1126, formed another period of Chalukya greatness. Vikramanka’s exploits against the Hoysala kings and others, celebrated by the poet Bilhana, were held to justify him in establishing a new era dating from his accession. With his death, however, the Chalukya power began to decline. In 1156 the commander-in-chief Bijjala (or Vijjana) Kalachurya revolted, and he and his sons held the kingdom till 1183. In this year Somesvara IV. Chalukya recovered part of his patrimony, only to succumb, about 1190, to the Yadavas of Devagiri and the Hoysalas of Dorasamudra. Henceforth the Chalukya rajas ranked only as petty chiefs.

 CHALYBÄUS, HEINRICH MORITZ (1796–1862), German philosopher, was born at Pfaffroda in Saxony. For some years he taught at Dresden, and won a high reputation by his lectures on the history of philosophy in Germany. In 1839 he became professor in Kiel University, where, with the exception of one brief interval, when he was expelled with several colleagues because of his German sympathies, he remained till his death. His first published work, Historische Entwickelung der spekulativen Philosophic von Kant bis Hegel (1837, 5th ed. 1860), which still ranks among the best expositions of modern German thought, has been twice translated into English, by A. Tulk (London, 1854), and by A. Edersheim (Edinburgh, 1854). His chief works are Entwurf eines Systems der Wissenschaftslehre (Kiel, 1846) and System der spekulativen Ethik (2 vols., 1850). He opposed both the extreme realism of Herbart and what he regarded as the one-sided idealism of Hegel, and endeavoured to find a mean between them, to discover the ideal or formal principle which unfolds itself in the real or material world presented to it. His Wissenschaftslehre, accordingly, divides itself into (1) Principlehre, or theory of the one principle; (2) Vermittelungslehre, or theory of the means by which this principle realizes itself; and (3) Teleologie. The most noticeable point is the position assigned by Chalybäus to the “World Ether,” which is defined as the infinite in time and space, and which, he thinks, must be posited as necessarily coexisting with the Infinite Spirit or God. The fundamental principle of the System der Ethik is carried out with great strength of thought, and with an unusually complete command of ethical material.

 CHALYBITE, a mineral species consisting of iron carbonate (FeCO3) and forming an important ore of iron. It was early known as spathose iron, spathic iron or steel ore. F. S. Beudant in 1832 gave the name siderose (from , iron), which was modified by W. Haidinger in 1845 to siderite. Chalybite (from ,  , Lat. chalybs, steel) is of slightly later date, having been given by E. F. Glocker in 1847. The name siderite is in common use, but it is open to objection since it had earlier been applied to several other species, and is also now used as a group name for meteoric irons. Chalybite crystallizes in the rhombohedral system and is isomorphous with calcite; like this it possesses perfect cleavages parallel to the faces of the primitive rhombohedron, the angles between which are 73° 0′. Crystals are usually rhombohedral in habit, and the primitive rhombohedron r{100} is a common form, the faces being often curved as represented in the figure. Acute rhombohedra in combination with the basal pinacoid are also frequent, giving crystals of octahedral aspect. The mineral often occurs in cleavable
