GREAT COPPER BALLOON AT PARIS
A vast deal Of interest has been excited in
Paris by the near completion Of an i'm
menso balloon Of copper, which has been
so far constructed as 10 be exhibited to the
public. N. Marcy Monge, is the artist of
the great work; and considerable impor-
tancc is attached by scientific persons to
the promised result, viz: the employment
of this balloon in the determination Of
electric and magnetic phenomena. In this
case, NJ. Arago will introduce the matter
TO the French Institute. The balloon is
entirely composed Of sheets Of copper, The
200th part Of an inch in thickness; /: is
about ten yards in diameter, weighs 500
pounds, and will contain 100 pounds Of
hydrogen gas. NJ. Marcy Monge states,
that by its use he shall be enabled 10 stee
through the air, by a system which he haB
already deyelopedin memoir submitted 10
the French Academy. lie maintains that
by substituting copper for silk be shall be
able altogether 10 prevent the escape Of
the gas, so that the Tronaut may remain


in the air for any length Of time; and thus
be enabled to study the atmospheric cur
rents better than he could do during such
ascents as have been made in silk balloons.
Again By keeping the copper balloon for
a long time in the atmosphere, and con
meeting II with the earth by a wire, NJ.
Marcy Monge expects to conduct the cleo
trical matter from the clouds, and thus
prevent the formation Of hail, which is so
destructive to agricullure.-[M ~. Y. Gas.
