DE- TRIsBLEr's SrIAH AND ETHER EsstyE.-
Late accounts indicate that the invention tried few
year. ago at the Novelty Works in this city, and later
on very extensive scale on some steamers the
Nsditer1snesn, of employing the heat Of exhaust
s'esm TO work an ether engine, has been proved IN.
practicable. Ether is so much more volatile than
water, that it was hoped considerable gain of power
could BE- realized from ether Ene worked with
out any cost for fuel but the practical difficulties APP
pear TO have de.troyed such hopes. The fact still re-
mains that ordinary steam engines deyeope and utl
ize only from FIVE to ten per cent OF tue power actually
contained in the heat yet this it is Do, in the
present saie Of science the way to improve thereon
The immediate cause on he abandonment of the ether
apparatus on the large steamers Le Jacquard and
ogo the gradual escape Of the vapOr of ether
through the stuffDg boxes. It is probable that steam
leaks gradually the manner, but the loss is not
as serious in such case. The L. JacguGrd is reported
to have los in this way barrel or more OF ether every
day.
FLED HEATERS FOR LocoHoTNEs.-About one.
seventh more fuel is required TO change cold water
into steam than is required previously heated nearly
to boiling Heaters deriving their heat from the spent
or exhaust steam from the engine in common use
on all hgh.pressure stationary engines, but are gen.
era y too cun.brous to be be Used On locomotives.
Several inventions have been patented, however,
within few years, designed for locomotive use

the latter pan consisting o: many rpes extending up
and down tie interior OF the chimney, has met with
considerable favor and is in on 10 less than
% locomotives on one road in the West.
CREAMER's SELF-AcrISG BRAKE OPERATOR -
w. Creamers invention for applying all the brakes
on trsin Of at the will of the engineer has been
several times proved the of saving life and
property. Why is it not more generally introduced on
railroads The plan consists in detaching by pulling
on the belcord, certain powerful springs previously
wound up by the blakemen. The practical difficulties
which hindered its success on its trst introduction
have been pretty satisfactorily overcome in the more
recent constructions, and the various rival schemes
sc, to have quietly Withdrawn. If there is no bet
ter device before the public Creamers brake opera-
oIs should be at adopted all passenger trains
case hes been recently reported in which man who
had taken four grains Of strychnine was kept IN Ter
the influence of chlorofOr until an emetic finally
after several unsuccessful attempts induced to operate
The spasms returned in few minutes, however, and
the patient finally kept under the influence Of
chloroorm for eight hours after which the effects of
the poison were TO longer visible. One grain of
stry chime ID usually sufficient to induce death.

composition patented by Eleazor Brown. jr of Bing
bamtop, this State, in July, 1855, as ubrcator for
the boxes Of railroad cars. The material is in quite
success sfu use several railroads.
