The department of Cajamarca lies between the Western and Central Cordilleras and extends from the frontier of Ecuador S. to about 7° S. lat., having the departments of Piura and Lambayeque on the W. and Amazonas on the E. Its area according to official returns is 12,542 sq. m. The upper Marañon traverses the department from S. to N. The department is an elevated region, well watered with a large number of small streams whose waters eventually find their way through the Amazon into the Atlantic. Many of its productions are of the temperate zone, and considerable attention is given to cattle-raising. Coal is found in the province of Hualgayoc at the southern extremity of the department, which is also one of the rich silver-mining districts of Peru. Next to its capital the most important town of the department is Cajamarquilla, whose population was about 6000 in 1906.

CAJATAMBO, or Caxatambo, a town and province of the department of Ancachs, Peru, on the western slope of the Andes. Since 1896 the population of the town has been estimated at 6000, but probably it does not exceed 4500. The town is 110 m. N. by E. of Lima, in lat. 9° 53′ S., long. 76° 57′ W. The principal industries of the province are the raising of cattle and sheep, and the cultivation of cereals. Cochineal is a product of this region. Near the town there are silver mines, in which a part of its population is employed.

CAJETAN (Gaetanus), Cardinal (1470-1534), was born at Gaeta in the kingdom of Naples. His proper name was Tommaso[[1]] de Vio, but he adopted that of Cajetan from his birthplace. He entered the order of the Dominicans at the age of sixteen, and ten years later became doctor of theology at Padua, where he was subsequently professor of metaphysics. A public disputation at Ferrara (1494) with Pico della Mirandola gave him a great reputation as a theologian, and in 1508 he became general of his order. For his zeal in defending the papal pretensions against the council of Pisa, in a series of works which were condemned by the Sorbonne and publicly burnt by order of King Louis XII., he obtained the bishopric of Gaeta, and in 1517 Pope Leo X. made him a cardinal and archbishop of Palermo. The year following he went as legate into Germany, to quiet the commotions raised by Luther. It was before him that the Reformer appeared at the diet of Augsburg; and it was he who, in 1519, helped in drawing up the bull of excommunication against Luther. Cajetan was employed in several other negotiations and transactions, being as able in business as in letters. In conjunction with Cardinal Giulio de' Medici in the conclave of 1521-1522, he secured the election of Adrian Dedel, bishop of Tortosa, as Adrian VI. Though as a theologian Cajetan was a scholastic of the older Thomist type, his general position was that of the moderate reformers of the school to which Reginald Pole, archbishop of Canterbury, also belonged; i.e. he desired to retain the best elements of the humanist revival in harmony with Catholic orthodoxy illumined by a revived appreciation of the Augustinian doctrine of justification. Nominated by Clement VII. a member of the committee of cardinals appointed to report on the "Nuremberg Recess," he recommended, in opposition to the majority, certain concessions to the Lutherans, notably the marriage of the clergy as in the Greek Church, and communion in both kinds according to the decision of the council of Basel. In this spirit he wrote commentaries upon portions of Aristotle, and upon the Summa of Aquinas, and towards the end of his life made a careful translation of the Old and New Testaments, excepting Solomon's Song, the Prophets and the Revelation of St John. In contrast to the majority of Italian cardinals of his day, Cajetan was a man of austere piety and fervent zeal; and if, from the standpoint of the Dominican idea of the supreme necessity of maintaining ecclesiastical discipline, he defended the extremist claims of the papacy, he also proclaimed that the pope should be "the mirror of God on earth." He died at Rome on the 9th of August 1534.

CAJUPUT OIL, a volatile oil obtained by distillation from the leaves of the myrtaceous tree Melaleuca leucadendron, and probably other species. The trees yielding the oil are found throughout the Indian Archipelago, the Malay Peninsula and over the hotter parts of the Australian continent; but the greater portion of the oil is produced from Celebes Island. The name cajuput is derived from the native Kayuputi or white wood. The oil is prepared from leaves collected on a hot dry day, which are macerated in water, and distilled after fermenting for a night. This oil is extremely pungent to the taste, and has the odour of a mixture of turpentine and camphor. It consists mainly of cineol (see Terpenes), from which cajuputene having a hyacinthine odour can be obtained by distillation with phosphorus pentoxide. The drug is a typical volatile oil, and is used internally in doses of ½ to 3 minims, for the same purposes as, say, clove oil. It is frequently employed externally as a counter-irritant.

CAKCHIQUEL, a tribe of Central American Indians of Mayan stock, inhabiting parts of Guatemala. Their name is said to be that of a native tree. At the conquest they were found to be in a much civilized condition.

CALABAR (or Old Calabar), a seaport of West Africa in the British protectorate of Southern Nigeria, on the left bank of the Calabar river in 4° 56′ N., 8° 18′ E., 5 m. above the point where the river falls into the Calabar estuary of the Gulf of Guinea. Pop. about 15,000. It is the capital of the eastern province of the protectorate, and is in regular steamship and telegraphic communication with Europe. From the beach, where are the business houses and customs office, rise cliffs of moderate elevation, and on the sides or summits of the hills are the principal buildings, such as Government House, the European hospital and the church of the Presbyterian mission. The valley between the hills is occupied by the native quarter, called Duke Town. Here are several fine houses in bungalow style, the residences of the chiefs or wealthy natives. Along the river front runs a tramway connecting Duke Town with Queen Beach, which is higher up and provided with excellent quay accommodation. Among the public institutions are government botanical gardens, primary schools and a high school. Palms, mangos and other trees grow luxuriantly in the gardens and open spaces, and give the town a picturesque setting. The trade is very largely centred in the export of palm oil and palm kernels and the import of cotton goods and spirits, mostly gin. (See Nigeria for trade returns.)
