meteorological stations is after the type invented by Dr. Robinson of Armagh. It consists of four hemispherical cups A attached to the ends of equal horizontal arms, forming a horizontal cross which turns freely about a vertical axis B. By means of an endless screw carried by the axis a train of wheelwork is set in motion; and the indication is given by a hand which moves round a dial; or in some instruments by several hands moving round different dials like those of a gas-meter. It is found that the centre of each cup moves with a velocity which is almost exactly one-third of that of the wind. There are various other forms of the instrument, one of which is portable, and is especially intended for measuring the velocity of currents of air passing through mines, and the ventilating spaces of hospitals and other public buildings. The direction of the wind as indicated by a vane can also be made to leave a continuous record by various contrivances; one of the most common being a pinion carried by the shaft of a vane, and driving a rack which carries a pencil.
Anem´ŏnē (Gr. anĕmos, wind), wind-flower, a genus of plants belonging to the Buttercup family (Ranunculaceæ), containing about ninety species, found in temperate regions, three of them occurring in Britain: the white-flowered (A. nemorōsa), the only one truly native; the blue-flowered (A. apennīna); and the yellow-flowered (A. ranunculoides), a common European species naturalized in some parts of Britain. Several species are cultivated as florists' flowers.
Anemoph´ilous, said of flowers that are fertilized by the wind conveying the pollen.
Anem´oscope, any contrivance indicating the direction of the wind; generally applied to a vane which turns a spindle descending through the roof to a chamber where, by means of a compass-card and index, the direction of the wind is shown.
Aneroid Barometer. See Barometer.
Ane´thum, a genus of plants; dill.
Aneu´rin, a poet and prince of the Cambrian Britons who flourished in the seventh century, author of an epic poem, the Gododin, relating the defeat of the Britons of Strathclyde by the Saxons at the battle of Cattraeth. See Celtic Literature.
An´eurism, or Aneurysm (Gr. aneurysma, a widening), the dilatation or expansion of some part of an artery. Aneurisms arise partly from the too violent motion of the blood, and partly from degenerative changes occurring in the coats of the artery, diminishing their elasticity. They are therefore more frequent in the great branches; in particular, in the vicinity of the heart, in the arch of the aorta, and in the extremities, where the arteries are exposed to frequent injuries by stretching, violent bodily exertions, thrusts, falls, and contusions. An internal aneurism may burst and cause death.
Angara´, a Siberian river which flows into Lake Baikal at its N. extremity, and leaves it near the S.W. end, joining the Yenisei as the Lower Angara or Upper Tunguska.
Angel (Gr. angelos, a messenger), one of those spiritual intelligences who are regarded as dwelling in Heaven and employed as the ministers or agents of God. To these the name of good angels is sometimes given, to distinguish them from bad angels, who were originally created to occupy the same blissful abode, but lost it by rebellion. The Old Testament represents them as messengers of the Divine will, and Christ spoke of them more than once (St. Matt. xviii, 10; St. Luke, xv, 10). Generally, however, Scripture speaks of angels with great reserve, Michael and Gabriel alone being mentioned by name in the canonical books, while Raphael is mentioned in the Apocrypha. The angels are represented in Scripture as in the most elevated state of intelligence, purity, and bliss, ever doing the will of God so perfectly that we can seek for nothing higher or better than to aim at being like them. There are indications of a diversity of rank and power among them, and something like angelic orders—Michael, Gabriel, Raphael, Uriel, &c., seraphim and cherubim. They are represented as frequently taking part in communications made from heaven to earth, as directly and actively ministering to the good of believers, and shielding or delivering them from evils incident to their earthly lot. That every person has a
