GREAT DISCOVERY
ux,orfments With Liquofled Air
same of its Marvellous Powers.

Chautsuqua, N. Y, Aug. Il, 1879.
have just Witnessed some eXperl
ments with liquetled air which wore s
wonderful that | am sure your reader
win be interested IN nearing "oou t..'

Consequently tho liquid air, unless

lion Yet, even while boiling, II Is
colder than ice by many degrees, ana
viii Instantly freeze whatever comes
in contact with it. AS the operator
dipped it up from the can the l"a'e
would be Immediately coated Win
FROST and when vessel oi IL WAS
nlaced in cold water, the liquid air at
once began to boil furiously lrGm tEo
heat of the water around the vcssci,
forming q crust OF ice SO hard that IT
could be readily removed and used as
a tumblcr. Into this ice tuinbicr more
LIQUID air was poured, which Instantly
bcpau 70 boil from contact with the
ice. The hydrogen, of the air, Dclns
lighter than the oxygen cVaporate2 more
quickly, and as every school boy Knows
that oxygen is ~ great promoter ol
combustion, the liquid "ir, after losing
its hydrogen, becomes medium ior
producing the tcrGcst heat though
itself so intensely cold. Now YOU Will DC
prepared to believe me wncn tell you
thatu a piece OF wire with carbon point,
when plunged into this ice tumDlcr
filed with a liquid BIZ degrees hcio"
zero, began to burn with tcmpcra-
turc Of nearly 5000 degrees above
boiling water, anu Dhrncd away I'LL
the wire was consumed like a straw .
On the same principle piece OF
WOODEN felt that could not be made TO
burn when ignited in common air,
blaZcd NJ like rOsin when saturated
with the liquid, and q flock Of common
cotton WOOL exploded like gun cotton,

Hence can be seen the great possibili-
ties Of this latest discovery Of science
in the cremat.UG q garbage and the
manufacture Of explosives.
In color and consistency liquid air is
Just like clear water, but cvap0ratcs 50
quickly that it will not wet anything,
and being heavier than common air
its vapOr, instead Of rising, like the
vapor Of water ana like common smoke
falls to the earth. Plunge your hand
kerchicf into it, and the handk crchicf
will smoke az il on fire, while drops Of
the chilling liquid fail TO the floor, but
there is no sign Of moisture. Pour Il
bucket full Of it on the floor and there

be seen. n bunch Of roses immersed
in vessel OF it retained their natural
appearances but became frozen so hard
IN lew seconds that they shivcrcd
like glass when thrown upon the floor.
The same thing happened to potato
and piece OF beef, which had to be
broken with hammer like stones
after remaining about 20 seconds in
.lf,t Il -
lrceHes at temperature Of something
IKE zoo degrees below zero, became
solid ice in about half minute, and
mercury, IN scarcely double that time,
lroZc SO hard that it WAS used as Il
manner TO drive two large nails into u
board.
Still more curious effects we're pro-
uuced when little water was poured
into tea kettle filled with LIQUID air
anu placed on lump OF ice. The kettle
Immediately began to boil so RAPIDLY

kerosene stove and not only did the
water turn to ice as before, but tho

lnls intense cold, may remark in
passing, Is the great obstacle in the
use use OF liquid air as a motor power,
Whlic Its expansive force is twenty
tlmes greater than that OF steam, tho
intense cold produced by its exDansion
causes any machinery to which it is
appllcd TO become so heavily cloppnd
