Perth, town, capital of West Australia> on

natural beauty, and the city is well built,
with wide streets and numerous fine build-

Perth Amtoy, city, New Jersey, Middle-
sex co., on Raritan Bay, at the mouth of the
Raritan River. It is connected by a bridge
with South Arnboy. A bridge links it to
Staten Island (New York City) at Tot-
ten ville. Features of interest are the
capitol building of the province of East
Jersey, and the barracks used by the English
soldiery. William Franklin, the last royal

governor of New Jerseyt was captured here
in 1776. Industrial establishments include
manufactures of terra cotta, lead, copper,
steel, cable, emery, and chemicals; and the
city has shipyards and drydocks. The first
settlement was made in 1683 and the place
was named in honor of the Earl of Perth.
Aniboy, a corruption of Ompage, the original
Indian name, was added by popular usage.
It was the capital of the province from 1684
until about the time of the Revolution.
It is a port of entry and is served by the
Central Railroad of New Jersey, the Le-
liigh Valley Railroad and the Pennsylvania
Railroad; p.41,242.

heart of Scotland. In the north the Gram-
pian Mountains cover a large area. The
rivers Tay and Forth drain Loch Tay,
Loch Katrine, and many other picturesque
lakes.

Perturbations, an astronomical term de-
noting inequalities in the motions of the, heav-
enly bodies due to irregular attractions. Those
affecting the planets arc classed as periodic
and secular. The first kind depend upon the
relative positions of the disturbing and dis-
turbed body: they alter the place of the lat-
ter in its orbit, not the orbit itself; and they
are compensated when the original configura-
tion of the two planets and the sun is re-
stored. They are hence comparatively tran-
sient and of small amount. Secular perturba-
tions are conditioned by the slowly modified
relative positions of the various orbits, and
are compensated when these revert to their
primitive status as regards each other and
the plane of the ecliptic. They accordingly
require immense' lapses of time for their de-
velopment. Lunar disturbances result from
the unequal action of the sun, and are due to
the difference in the attraction of the sun at
a given moment upon the earth and moon.
They are mostly periodic. The orbits of com-
ets are often radically altered by planetary
influence. The return to perihelion of known
comets is, besides, advanced or delayed by
th'e attraction of the planets met with on the
way.
