Art and science.

Mr.. Waldack, of Cincinnati, in spite of
difficulties unknown to the ordinary prac-
tibe of photography, has succeeded in TAX
ing number of beautiful stereoscopic
views of the Mammoth cave, as clear and
vivid DIS if they were sun paintings.
1t has lately been discovered that the
whole of the sulphur used at present in IL
Illuminating gas land which makes the gas SO
offensive) may be removed by bringing it
it in contact with the ammonical liquor
which is an almost worthless product Of
the same gas-works.
The inhabitants Of Baku, on the Cas-
plan sea, have recently utilized the emana-
tions of carburetted hydrogen gas which
rise from the waters, for lighting purposes.
The gas is collected by means of large fun
mel mouthed tubes, which are attached to
floating RATS and dip some feet into the
water.
The Cooper Union for the advancement
of science and art, has just celebrated the
expiration of its seventh academic year
The number of pupils that have been under
instruction for the past year exceeds two
thousand, of whom less than one hundred
have paid tuition fees, the residue being
benifciaries. In the female art department
the increase over any previous year was
206. There are three classes Of pupils, ar
ranged according to the object of their
studies: Amateurs, free pupils preparing
to'beeome teachers, and the Industrial class,
composed of those who desire to make art
profession.
Among the latest and most valuable
contribution of science to art is the new

coyery of Alexander Parke, of Birming-
ham, England, and in its basis bears some
affinity to gun-cotton, being explosive to
high degree. The inventor, however,
has brought this quality under control, and
the plastic character OF the material is
such as to render it invaluable for the pro-
duction of fac-similes Of ancient gems,
canoes, and such like objects of art. 1t is
also applicable, to valuable extent, to GER
tain processes connect with Photographic
art.
"A scientific way of lighting pipes and
cigars has been recently introduced in Paris
under the name of poudre de fue 1t con-
sists of pyrophorus, which is preserved in
small tin case with narrow orifce
When a little Of this black powder is poured
out on the end Of cigar, or on the tobacco
in pipe stem, and then gently breathed
upon, it become incandescent, and is in a
condition to light said pipe or cigar What
next? Why there are little tubes sold con-
tanning pellets of potassium, and they are
recommended to the Juvenile Parisians as
means of forming splendid Gregorian
fireworks, on any convenient piece of wa
ter
A Buffalo letter describes an invention
for the preservation of dead bodies, in case
of deferred funerals, and for shipping
corpses long distance. 1t is in the shape
of coffin or burial case; is made Of paraf-
fine cloth, in duplicated walls, the alternate
chambers being filed with cotton, feathers,
etc. The outside is composed of patent
leather. On the lid is fixed a square box,
in which ice is placed, and which has con-
Meeting pipes with the chambers, ETC., the
whole constituting perfect and powerful
refrigerator Ii has been discovered by
scientific experiments that decomposition
of animal matter cannot take place az d
temperature of As degrees; and this refrig-
orator is capable of producing a tempera-
ture as low as % degrees win very small
quantity of ice and salt. For ordinary
poses it is not necessary to use anything
but ice to preserve the body. Bodies can be
shipped in warm weather in this case, dis
lance of one thousand miles without re-
plenishing ice.
