act of informing or notifying; notification. [Archaic] An advertisement of danger. Bp. Burnet.

Tending to affect; affecting. [Obs.] Burnet.

sics), an imaginary line on the earth's surface passing through those places where the magnetic needle points to the true north; the line of no magnetic variation. There is one such line in the Western hemisphere, and another in the Eastern hemisphere.

c notice; to display ostentatiously; as, to air one's opinion. Airing a snowy hand and signet gem. Tennyson.

An air-filled gap in a magnetic or electric circuit; specif., in a dynamo or motor, the space between the field-magnet poles and the armature; clearance.

Alignment; position in a straight line, as of two planets with the sun. Whewell. The allineation of the two planets. C. A. Young.

See Garnet.

The common red variety of garnet.

Rays of relatively low penetrating power emitted by radium and other radioactive substances, and shown to consist of positively charged particles (perhaps particles of helium) having enormous velocities but small masses. They are slightly deflected by a strong magnetic or electric field.

A beautiful mottled and curled wood, used in cabinetwork. It is obtained from the Pterocarpus Indicus of Amboyna, Borneo, etc.

olutions and carrying a current of half an ampère is said to have 2½ ampère turns. The magnetizing effect of a coil is proportional to the number of its ampère turns.

y U. S. Statute as, one tenth of the unit of current of the C. G. S. system of electro-magnetic units, or the practical equivalent of the unvarying current which, when passed through a standard solution of nitrate of silver in water, deposits silver at the rate of 0.001118 grams per second. Called also the internationa…

unction depends; -- a term used more especially in connection with elliptic functions. Magnetic amplitude, the angular distance of a heavenly body, when on the horizon, from the magnetic east or west point as indicated by the compass. The difference between the magnetic and the true or astronomical amplitude (see 3 abo…

Having lost, or tending to lose, inflections by phonetic decay; as, anaptotic languages.

by anastomosis, as the arteries and veins. The ribbing of the leaf, and the anastomosing network of its vessels. I. Taylor.

A resinoid coloring matter obtained from alkanet root.

e. -- Angular motion, the motion of a body about a fixed point or fixed axis, as of a planet or pendulum. It is equal to the angle passed over at the point or axis by a line drawn to the body. -- Angular point, the point at which the sides of the angle meet; the vertex. -- Angular velocity, the ratio of anuglar moti…

Consisting of the flesh of animals; as, animal food. Animal magnetism. See Magnetism and Mesmerism. -- Animal electricity, the electricity developed in some animals, as the electric eel, torpedo, etc. -- Animal flower (Zoöl.), a name given to certain marine animals resembling a flower, as any species of actinia or se…

Pertaining to the anomaly, or angular distance of a planet from its perihelion. Anomalistic month. See under Month. -- Anomalistic revolution, the period in which a planet or satellite goes through the complete cycles of its changes of anomaly, or from any point in its elliptic orbit to the same again. -- Anomalistic…

The angular distance of a planet from its perihelion, as seen from the sun. This is the true anomaly. The eccentric anomaly is a corresponding angle at the center of the elliptic orbit of the planet. The mean anomaly is what the anomaly would be if the planet's angular motion were uniform.
