and Gliding By Porc-
dered Tin.

The Moschus and Nesquashes of India
use an application in ornamenting their
work that stands The effect of the wealth
er, nearly equals gliding, and costs little
more than common pant, which might
be useful for ornamenting and preserv-
ing iron work with smooth surface
In preparing this Fictitious gliding,
quantity of pure tin is melted and pour
ed into Joint of bamboo, closed at each
end, which is instantly plugged up. The
bamboo is then violently shaken, which
makes the metal assume, when cold,
the form of a very fine gray powder;
this is then sifted, to separate any coarse
particles, and is mixed with melted glue,
When it is applied, it should be re-
duced by the addition of water 10 the
conscience of thin cream, and is then
laid on with soft brush, like ordinary
paint; when dry, it appears like coat
OF common gray water color, until it is
gone over with an agate burnisher, and
then forms bright uniform surface of
polished tin; a coat of white or gold
coIored oil varnish is Immediately laid
over it, according as it may be intended
TO initiate silvering or gliding. A simi-
lar powder is sold by the druggists as
powdered tin but their powder is not
usually fine enough. If the glue be toe
strong, the burnisher has no effect and
if too weak, the tin crumbles off under
the agate.
Perksns's Extraordinary Steam gun.--
The London Mechanics Register con-
tains an interesting account of this MUIR
derous engine, which was exhibited at
Mr.. Perkins works. Regents Park, on
the Sd inst. This piece of mechanism
is formed BY simply introducing barrel
into the steam generator of any engine,
and the addition of two pipes towards
the chamber of the gun, Introducing a
quantity of balls, which, by the action of
the handle to the chamber, are dropped
into the barrel, and fired Que by one, al
the rate of from four to five hundred in
the minute. The explosive force Of
the steam, which rushes from the gener-
ator and expels the balls, is about seven
hundred pounds to the square inch: with
this force musket ball fired against an
iron plate, at the distance of an hundred
feet from the gun, is completely hatten-
ed, and when force of 84Ob. 10 the
square inch is applied, the ball is actual.
ly driven to pieces in such way that
none of its fragments can be collected.
Mr.. Perkinsis about 10 construct four
pound tield-piece on this principle,
which may be drawn by two horses
The most extraordinary part of the af-
fair is, that one pound of Goals is found
to produce the same effect as four
pounds of gunpowder in the ordinary
way. 1t is said of this engine of destruc-
ton, elf any two rulers Of the earth
were to know, that in the event of de-
claring war against each other, plague
or pestilence would blast both armies,
and sweep. them from the face of the
earth, they would pause before they
made such declaration. But what
plague, what pestiIence, would exceed
10 IFS effects those Of the Steam-gun p
Five hundred balls fred every minute,
and one out of twenty to reach its, mark
why, ten ofsuch guns would destroy
10000 men daily. Mr.. Pe.kins con-
Eslders steam discovery as in its infancy,
fer he says he is convinced that steam
engine might be made TO throw ball a
ton weight, from Dover to Calais"
