will briefly describe the apparatus by
which this wonderful result is produced
From the dome Of the Pantheon is
suspended small wire, about 270 feet
IN length, 10 the lower end of which is
fastened a metallic ball six or seven
inches in diameter, and at the bottom of
that is a sharp point. The wire is made TO
vibrate as pendulum, and in IFS vibrations
the point marks the surface of a round
table under il some twenty feet IN diane
ter. The table is stationary, but notwith-
standing complete revolution once in
every "a hours, not round its own centre,
but round the centre of The earth; and
the consequence is, that its whole cir
cumferepce is regularly marked all round
by the sharp point with lines radating
from the centre, so that the degrees,
minutes, and seconds, appear with per-
feet accuracy, and at uniform distances; !;
and the marking of any one hour Of the
"a will correspond precisely with that Of
any other, the distance representing Of
course exactly. fifteen degrees-on the
table two feet and a .half-time one hour
which is the distance the table has
travelled, whilst the earth has moved from
FIVE TO six hundred miles. The table
can be seen whilst the ball is vibrating,
which is in in truth seeing the earth
move. uf C -
The explanation of this very curious
exhibition is as follows: The dome from
which the wire is suspended and the
table make complete revolution round
the centre Of the earth in ID hours; but
the plane in which the pendulum oscil-
ates has no rotary motion, and is not aft
ected by that Of either the earth, the dome
or the table. Consequently the plane or
the bali seems 10 make complete revo.

Had this curious apparatus been ex-
hibited at Rome at the time Calico was
made to abjure on his knees great as
Economical fact, the exhibitor would not
have escaped by recantaiion and abjura-
ton, but would have been consigned to
the flames as sorcerer, as hereto, and
for dealing with the devil. Here is an
overt act, visible, palpable miracle ap.
parently, whilst Calico went no further
than to entertain opinions, which were
very near being purged out of him by the
grand Inquisitoriai recipe-fire.
A writer in the Newark daily Adcerti.
ser says he has tried the Parsan expert
ment, and with perfect success. His
apparatus consisted of a Sc pound iron
| weight, and wire 80 feet in length sus-
pended from the roof Of his barn, a sharp
point being fastened 10 the lower side of
the weight TO register its movements on
the floor. The pendulum was set in
motion in direction of east and west,
and in less than fifteen minutes dcviated
very perceptibly, and in three hours had
changed TO north west & south east, being
the eighth par.o an entire revolution, and
corresponding with the time, which was
one-eighth of twenty four hours. As the
plane in which the pendulum oscillated
did not change its apparent DETECTION is
attributable of course, and TO nothing else,
but TO the earth's diurnal motion, Without
which motion it would vibrate forever,
we suppose, IL not stopped or disturbed,
in the direction given it by the first i'm
pulsion. This experiment seems to be
very simple and easily made, but that does
not detract in any manner from tine merit
of nj. Foucalt, who has discovered and
demonstrated the principle on which it
depends.
