MR.. PERKINS STE VI ENGINE.
LIVERPOOL, April 8,-We extract the
follrwirg description OF Mr. Perkins pa
tent from a letter in the Pottery q eZette.
OF course, we do not vOuCh for its accura-

very Ineligible but We give it because
every thing relating TO an invention so stu
psndous as tins is said TO be, must possess
interest -
"iie has no boiler, properly so called,
but bis generator, as be terms n, is about
feet high by feet in diameter, of ex-

which and the turnance he Grams full OF
earth, to prevent any heat coming out, and
being lost. The water in the generator,
which is Of course always fulk he keeps
under great pressure by means OF pipe
communicating with forcing pump. The
steam ia communicated 10 he piston cyiin-
Ger ~ the usual way; this works bOrZOn-

steam which has acted is carried 10 the
condensing well. and thence back again
10 the forcing pump. The water never
boils; it is heated, | believe, TO about 500
degrees water boils you know, al GIG

wari into the conducting pipe. On this
cOnduc,in pipe is placed a safety bulb ct
wrought iron, thus, .: this bulb is
made at one balf OF the strength OF any o.
Their part OF the machine You will have
aru e notion of the whole thing from this
description. Al the persons in Lon.
don best qualified to judge of it, think Ia
Yorably of 1t; but nothing bat proof will
do. and that we shall have in fortnight,
hope. II will produce gre ter revolu

The voyage TO America will be reduced
to 10 days. There i. another invention
Of COMPRISING gas into small cylinder,
and selling il Tor candles. A company IS
formed which is 10 distribute them every
morning, calling for an empty cylinder,
and Ieavlng a iuIl one. 1t will stand on
your table like a lamp. and will be chea :

that Mr., Perkins has taken out patent
tor England, Scotland and Ireland, for the
United States, France and Germany,
which shews be is very confident"

We have received, (says the \ 7 Mer,

high, aud the apprehensions appear well
grounded OF a general overflow OF the
Country,
The steam boat General Robinson, from

would eventually be got out.
