state of water. Two years since
Mr.. B. published, ION this subject, q
book which is of the most attractive
kind, and he says at the close that
he is in the way Of finding the princi-
pie of a practical application to tho
formation Of steam.
On speaking with Mr.. Boutigny
on this subject, you recognise first
rate chemist, but though he has a
theoretical knowledge Of mechanics,
he is not an engineer.
Happily, at this point Of the dis.
covery, civil engineer, Mr.. Cestud
dc Beauregard entered the field,
and, as will be seen by the following,
has reaped a rich harvest.
III the Rue du Fauborg st. Den.
mis-, No. 1872, at Paris, MIR. G.. de
B. has erected q steam engine Of 500
horse power on his new plan. In
place of the common boiler with its
tubes and other complications, he
employed single vessel with a Fat
bottom, about one-ffticth as large as
an ordinary boiler of the same power.
It is inclosed in o brick furnace
above fre-grate Of reduced dimcn-
sions. This vessel is always empty
of water. Connected with the bot
tom are two pigomcters to indicate its
temperature, and on the cover is q
valve, which you open when you wish
to stop the engine in an instant. No
manometer or safety apparatus is
needed.
The work is 80 constructed as to
keep the bottom of the boilers Mt the
temperature of $50 Fahrenheit, and
the principle which serves for q basis
is this: d
Whom small quantity Of water is
cast upon surface heated to $50
Fahrenheit or more, it is reduced to
steam whicl, iS forme.i and remains
at the same temperature of T50..
To use. the engine one or two Gu.
bic inches Of wassr are thrown into
the hot vessel, the water is all instant

After that the engine itself supplies
the boiler with the requisite small
quantity of water.
The steam leaves the cylinder at
the temperature of $50 and passing
through the water reservoi. Of q coil
of pipe, heats that water and raises
it to 212 before escaping into the at
lnosphere, or before being reduced to
water.
For the last three months Mr..
Bcauregard's works have been acces.

gineers and men Of science in Paris
have been there engaged during that
period in every kind of experiments;

factory and leads to the following
conclusion, with regard to the new
inventions:
1st. Economy Of fuel Of over fifty
per cent. The best boilers known
require three pound of coal per hour
for each horse power. The new sys.
tenn, only from one to one and half.
I'd. Reduction in the weight of
machinery over fifty per cent.
Sd. Security from explosion
The safety apparatus used ini is SIM
ply to prevent the boiler from being
injured by the FIRE; none is necessary
to prevent explosions; the vessel be-
ing always empty ofwater and empty
of water and steam, when the engihe
rests.
Snpposing all this to be true, as
We hope it will prove to be, the dis.
covery must produce a great change
in all branches of mechanics with
reduction Of the cost Of many articles
OF flrst necessity. Bnt tho main re.
cult will surely be, increased speed in
steam navigation The reduction of
weight in the new boiler will give us
power double that Of those now in use
without changing the draft Of the
vessel; and by the reduction in tho
consumption Of fuel the same cargo
Of coal will be sufficient to sail the
same number of days even with en-.
sincs of double the present power.
But as the trip will be performed in
ess number of days, a diminution in
The quantity focal taken on board
will still be possible.
