consists Of a separate vessel filed with cold water,
which acts as cover TO the pot. This vessel, being
Of peculiar form, presents large extent OF cold

times as much cold water in the condenser az evaPo-
rated in the pot. With a sufficient amount oil cod
water the device must be effective.
Mr>rFIY's PATENT CHURCH BrIL.-A pstent has
recently been granted for Improvement In hunting
church and OIL er bells that they may be turned
about in the yoke thus presenting fresh surface TO
the blow of the cspper and avoiding the Liability TO
break.
IyPRovraTSr ~ ELEcTRo.PLATISG.-Herry BRAD
bury of England has discovered process by which
engraved copper-f lates may be protected with an
electro deposit Of mich e thus increasing the duTabi"
ity Of the plate from 500 to 5000 impressions.
NJ Joub.r IT has al.o method of depositing iron for
,be same purpose. Mr. Bradbury, in controversy
with NJ Jouber', says:
Nickel gives a surface kinder, for printing pur-
poses than either STEEL copper or any OF the known
metals the reason being simply that in addition 70
hardness il possesses the smootheet, hrmec. Ahd

above elect o-iron facing il has hitherto been done.
The number of imp essoDs alone does not constitute
the sole in this particular application OF electro
facing. Electro.ron hitherto has varied from 00Oto

ment, whereas with proper manipulation there ought
not 10 be any variation
ASoTHER IcE-BoAT-The following is q description
of DIR. A. II. Trows Invention for ice communication:
at entirely different from WARDS boat in its
ners mode of driving, N ode of steering, and almost
everything else. lTOWs INVENTION u not intended I'd
TO carry passengers itse but is 10 perform the ice
the services which locomotives perform railroads,
and that is 10 drag the passenger boats after l..
This will distribute the weight larger spece, and
render the train lees liable to break through"
patent IR.S CAR.-One of these cars has been
recently built at Parersop n. j., for the Boston and
Worcester Road and i. in every respect most credts-
be TO the enterprise of the builder. The interior is
finished of in the most elegant manner. Every panel
hiss fine paper mache picture in it, representing sOme
vie Or q aeat arec
the yentilsors and apparently efficient. The
car OWING to The greater thDness Of the iron Sides is
eight inches wider than the narrow gauge cars are
usually, and weighs less by un than wooden car Of
the same dimensions.
EyESrIoN FOR RAILROAD CARs.-We saw yester-
day, saws The NerO Orleans Daiiy Delta OF the 10Th
inst, invention to be placed upon railroad carr,
to enable them to turn corners at night angles or
nesrly co. The invention is very simple, and would
astonisb almost any with its simplicity. The
whole thing is don, by the wheel, and not BY any
change in the axle nor by improved fifth Wheel a.
most persons would be likely to suppose. The in
ventor is about filing csyeat for patent, and when
that is secured the invention will be brought before
the public
