resident for some wears IN -. Lous, conceived the
idea III connecting the manufacture of vinegar and
white Il ad, and after small experiments applied
for patent, which was granted abou, eighteen months
since. TIE experiments having been enlarged and
promising great success he advised to leave s..
Louis fr this city, more suitable heid Of opsra-
ton Unfortunately, operations require anoaey in
larger sums than poor inventors often possess, 81 tha;
NOR than year elapsed before DC could OBTAIN as
sislarce enough to establish experimental msnaiac-
tory, even upcn the smallest scae. AT length he has
succeeded snd has demonstrated the truth OF his as
serons ard the claim il his patent, so far as be can
upon a mall scale, which, ii it holds good upon
large one. Will very greatly cheaper the manufacture
of White ,ead, beside rendering the business more
/ heshy.
In the manufacture O; white lead by tie cd process
The sheet lead placed in earthen pots with acid in
moderate heat, requires sye or six months t" be-
Gene sufficiently oxydzed; aud in this process large
Quantities # vinegar are wasted, as well INTEREST Of
money IL vested in lead lost.
In the new process, the fumes arising from the man
uiacture of negar are substituted for the liquid and
answer the purpose SO much better that alleged,
sheet lead of the same thickness wiki that used in
tin pots is corroded in eight days as 70 yield
much larger per'cen; of white lead-say 70 or . per
! e.n,-than is obtained in the old Way in five ot sax
| months At tire same time the conversion Vt ~ gal
lors OF whisky into 0 gallons of vinegar, such as sells
in this arket at eight cents gallon WILL Il Is eSti-
mated pay all the expense of converting the sheet lead
| into white lead of the very first quality.
The process of manufacture is extremely simple.
| Tie filtration Of the whisky aud water going on at
suitable heat in lower room, gives off It's fumes from
tie filters directly into air tight room above, where
the sheets of lead are arranged upon racks and where
the process Of oxidation be through glasses in
the Partition
The after process Of washing and separation Of the
oxide from the unoxdated portion is the same as in
the old process-the yield being greater and product
finer a. we Judge from the appearance of the sheets
in the chamber and from the lead in dry state aud
mixed with oil.
The capital necessary 10 establish mandatory
being less than heretofore the business will probably
soon be undertaken on large scale by this new pro-
cess and them if the theory and apparent truth of it
In the experiments of the inyentor are correct the
public will benefit from cheaper production OF a
much used article.
SLATE As A SUBSTITUTE FOR WooD FOR ESGRAv-
ERs.-According to the CoNrrier Franco Haliea, NJ.
Caruana historical painter of Naletta in the Island
of Malta has discovered that slate is superior to wood
for engravngs. 1t s, he alleges easily worked, re-
produces the finest lines with remarkable exactness
and resists longer than wood the action of the typo
graphical press so that several thousand copies of
design can be struck off without producing any sens-
be difference in the quality of the impression.
ANEW MOTIVE PowER.-We have been aware for
some time past that Prof Solomon was engaged IN oar
CITY constructing his patent SUI Oh Cdrbonic ACID
Engine aud that his prospects of success were highly
encouraging lie was aided in this enterprise by some
of our most opuleIt and intelligent cizens VINO, see;
ing the ultimate practlcbbllty oi ms INVENTION uld
not hesitate to furnish means enabling him to roach
the desired and-we ale happy to believe-tDrtunate
cousummaon. More than fen years has the Professor
abored upon this favorte theme 1T his mechanical and
scientific genius, occasionally encounterpg diihenes
but by close application and unbendng enterprise, he
finally found his efforts crowned with abundant sue
cess That which to him appeared certain IN theory,
coDsonant with mechanical laws and phlosophc prIn-
| cples has at last been Outwrought and practically
dtmonst aed-so far at least ~ our Judgment goes,
after seeing and judging for Oarsc vcsadmtting not
of doubt a. Ia It's complete triumph.
We called yesterday afternoon, much to our gratif-
cation and saw the engine IA full successful opera M
where il had been working without Interruption
several days in Cypress alley bet" cen Pratt aud n-
bard streets. The engine being merely model or
experimental one has OF course, some impcrfectlon,
and may be greatly improved, but il worked with r.
kable precision and regularity Ii is calculated Tor
iombone power being common reotilnes or recip-
rocatirg steam engine differing IN no material feature
from those in general use. The patent novelty con-
Sits in the motive power and it, application, which
wholly supersedes steam. This motor is produced by
a compound Of desulphurated bi-sulphuret OF carbon
coal tar and volatile or fixed OIL which, under certain
Influences of heat becomes powerfully expansive aud
thus gives momentum Though only n iour-hOrse
engine, ii performing the estimated duty OF ten
horses and has been doing since put into operation
