1803; heaviest of all metals; rare. It occurs in platinum ores

as an alloy of iridium. When heated, or treated with nitric
acid, it is converted into the peroxide, OsO4, the vapors of
which are poisonous. It is not used in the arts, but an alloy

Ostracism. Provision in the Athenian constitution, devised ab. 509 B.C. by Cleisthenes, to prevent any citizen from becoming too powerful. The citizens first carried a popular decree directing its use; then, on an appointed day, cast their votes by tribes, each writing upon an oyster-shell the name of the person whom he considered most dangerous to the state. The man having the highest number of votes, if at least 6,000, was banished for ten years, or, later, for five. Confiscation was not involved.

inch in diameter. The oyster spawns from May to August in
waters n. of the Chesapeake; the spawning season is more pro-
longed in southern waters. Both sexes spawn together, so
that the water becomes milky with suspended eggs and milt.
The eggs sink at the rate of a foot per hour. The majority
have settled into the mud by the time segmentation has begun,
unless the flowing tides produce whirling currents. The best
temperature for development is between 80° and 90° F. In ab.
12 hours the young embryo has advanced as far as the gastrula
stage, swimming by means of cilia. This locomotor stage
lasts for several days, and finally a shell of two equal valves is
formed, and two muscles, anterior and posterior, are devel-
oped. The anterior adductor never comes to a further devel-
opment. Then the young oyster, now resembling a clam,
settles on a clean object and cements itself by its left side. In
further development the body rotates so as to bring the front
end under the back (hinge) area, and the two shell valves grow
differently. See OYSTER CULTURE.

of agriculture has been introduced into both Americas. See

Otitis. Inflammation of the ear in any part. The most frequent seat of the disease is the middle ear, as the earache and gatherings in the ear so frequently noticed, especially in children. It frequently accompanies diphtheria and scarlet fever. The condition is always a serious one, apt to terminate in a chronic discharge (otorrhea) or in difficulty of hearing, and not infrequently will cause death. A disease of such danger cannot be safely left to domestic remedies. It is unwise to drop fluids in the ear, especially if one of the ingredients is a vegetable or animal oil. A douche of hot water, the application of cloths wrung out of hot water or a Japanese handstove to the external ear will usually relieve the intense pain. The discharge should be washed away by gentle syringing with a warm boric-acid solution. Further treatment than this is unsafe unless directed by a physician.
