at Paris, who, in the course of the year, COM
municates great amount of valuable scientific
intelligence. We have occasionally availed
ourselves of it, and continue to do so, when
we find such as will be likely to interest our
readers. We derive the following from his
last letter;
SUGAR MANuFAcTURE.-A German chem
list, named Sheutzenrbach, who has heretofore
made great improvements in the manufacture
of beet root sugar, has recently made another
very important one, which is spoken of with
enthusiasm by the French papers. 1t insures
great economy in the manufacture and can
hardly fail to extend it much more widely
than heretofore Indeed, with the improve
ments already made and being made, it would
be strange if the middle and north states
should before long, engage as successfully in
it as the French, Belgans and Germans have,
when the beet root sugar has almost entirely
superseded that made from the sugar cane and
driven it from their markets.
Many of the French beet sugar manufact-
urers have visited Prussia, where the new
process is already adopted, and having be-
come convinced of its great utility, have made
contracts with the inventor for its use in their
establishments. The improvement consists in
a new mode of ixivating or washing the pulp
instead of pressing it by means of hydraulic
presses-an apparatus large enough to work
l00, 900 to 10000 pounds of beet-pulp in
twenty-four hours, can be constructed and
put up for 81, 200 the same quantity OF pulp
would require six hydraulic presses, costing
5000 dollars. The cost of keeping these pres
SEES, in repnir averages about 20 per cent,
whereas i'll the new apparatus the repairs VIII
amount to about per cent. To work six n.y.
draulic presses requires six horsepower; the
new requires but two. This improvement at
fords not only great economy IN the first es-
Enlistment Of sugar mandatory Ill keep
ing it in order, in horsepower and manual
labor, but it enables the manufacturer to er-
tract 20 per cent more sugar from the same
quantity of pulp than by the old process
r. r. TRAIN TELEGRAPH. Professor
Glackman has invented a mode of establishing
communications between the brakeman of
trains by means of electricity which has been
lately tried with the express train from Eus-
ton square to Birmingham, and the results
have been highly satisfactory. The apparatus
consists of two batteries, each one secured
within box and placed at the opposite ends
of the train connected by a wire which pass
es under the cars and is joined to bells which
can be set ringing whenever the attention of
the brakemen or conductors is required The
great merit of this invention lies i'll its sim
plcity and rapidity Of action.
LIGHT FROM WArER.-Several notices have
appeared in the foreign papers, Of experiments
for procuring burning gas from water, by
means of electricity, similar to those made by
our former townsman, Henry M. Paine. The
experiments of Mr.. Shepard, it is said, prom
Use success. His electro magnetic gas appara-
tus, consists in seven rotary electro magnetic
machines to decompose water in seven separ-
ate receivers the gas which escapes from these
is conducted to gasometer and from there to
the burners. The secret consists in adding to
the water substance which has great affinity
for the oxygen which absorbs it as rapidly as
it is produced during the decomposition of the
water. The gas is mixed with too small
quantity of oxygen toproduce explosion. One
man can easily turn the electromagnetic ma
chine, and produce gas enough for seven or
binary burners.
HARDENING Brick, &c.-Experiments have
proved that porous sand stone and other stones
when stepped for about hours in hot coal-tar
C16O Reaumur) acquire a greater degree of
hardness, and become iaspermeable to scater.
Bricks require only four hours, and the coal
tar temperature of 80 degrees Reamur to be-
come hard as rock. The latter would answer
best for sidewalks They would also, be very
valuable for many purposes, where sohdity
and impermeability to water is desirable.
GnDING.-A new process of gliding or sill
vering lace and embroidery has been invented.
The specimens are beautiful, rich, retaining
all the delicacy of the thread. 1t will be
new means of ornamenting and embellishing
dresses of ladies, vestments Of Catholic priests
theatrical costumes, &C., and it will afford an
opportunity for the diplomatic corps to enrich
their fantastic disguise at very cheap rate
and especially suited for the ambassadors of
small powers.
