As´wail, the native name for the sloth-bear (Ursus labiātus) of the mountains of India, an uncouth, unwieldy animal, with very long black hair, inoffensive when not attacked. Its usual diet consists of roots, bees'-nests, grubs, snails, ants, &c. Its flesh is in much favour as an article of food. When captured young it is easily tamed.

Asy´lum, a sanctuary or place of refuge, where criminals and debtors sheltered themselves from justice, and from which they could not be taken without sacrilege. Temples were anciently asylums, as were Christian churches in later times. (See Sanctuary.) The term is now usually applied to an institution for receiving, maintaining, and, so far as possible, ameliorating the condition of persons labouring under certain bodily defects or mental maladies; sometimes also a refuge for the unfortunate.

Atacama (a˙-ta˙-kä'ma˙), a desert region on the west coast of S. America belonging to Chile, partly in the province of Atacama, partly in the territory of Antofagasta. It mainly consists of a plateau extending from Copiapó northward to the River Loa, and lies between the Andes and the sea. It forms the chief nitrate district of Chile, there being also rich silver-mines, while gold is also found, as well as argentiferous lead, copper, nickel, cobalt, and iron; with guano on the coast. The northern portion belonged to Bolivia until 1904. The Chilian province of Atacama has an area of 30,711 sq. miles, and a pop. of 63,893.

Ataca´mite, a combination of the hydroxide and chloride of copper, occurring abundantly in some parts of South America, as at Atacama, whence it has its name. It is worked as an ore in South America, and is exported to England.

Atahual´pa, the last of the Incas, succeeded his father in 1529 on the throne of Quito, whilst his brother Huascar obtained the kingdom of Peru. They soon made war against each other, when the latter was defeated, and his kingdom fell into the hands of Atahualpa. The Spaniards, taking advantage of these internal disturbances, with Pizarro at their head invaded Peru, and advanced to Atahualpa's camp. Here, while Pizarro's priest was telling the Inca how the Pope had given Peru to the Spaniards, fire was opened on the unsuspecting Peruvians, Atahualpa was captured, and, despite the payment of a vast ransom in gold, was executed (1533).

Atalan´ta, in Greek mythology, a famous huntress of Arcadia. She was to be obtained in marriage only by him who could outstrip her in a race, the consequence of failure being death. One of her suitors obtained from Aphrodītē (Venus) three golden apples, which he threw behind him, one after another, as he ran. Atalanta stopped to pick them up, and was not unwillingly defeated. There was another Atalanta belonging to Bœotia, who cannot very well be distinguished, the same stories being told about both.
