away in a mist, which proved that oxygen

later a. Pole of Warsaw Hauefied nitrogen,

that time Dewar, In England, made liquid

later he made ito for-$500 q pint. Mr..
Trlpler makes, liquid air for 20 cents a. gal
llon, and throws 1t about. as if 1t Is of no
consequence.
1t would be impossible, 1t Is claimed, to
accurately measure the intensity OF the
cold of the five gallons of LIQUID air con-
tained in tina reservoir placed before, the
company ct the Arlington last evening. Its
Intensity was shown. by experiment..

I Air is Eaueaed at 312 degrees below zero,
or 3S2 degrees belsw. the Temperature re-

liquid is constantly endeayorang to, return

water. It IL this property, 1t, fs shown,
that makes the liquid air a wonderful pos

{ Mr. Tripler began his exhibition by dip
ping a pan of liquid air from the reservoir.
1t boiled and steamed away as water from
the fire, yet 1t was cold and not heat that
was creating the commotion. Spilled, to
I the floor, 1t landed with a heavy sound,
{ like the striking of mercury, and yet in q
moment IT had turned to air, and was, being
/ breathed by the people who had just seen
it fall in solid state. Cupsful Of the
liquid was passed around. Fingers passed
through the substance gave. a sensation
similar to passing through heavy vapor
yet there was the heavy liquid as clear as
water; with a vapor arising, from it, If
passed through the. liquid rapidly the hand
experienced no intensity of cold, but If al
lowed to remain there few seconds an icy
chill would be experienced and more ex-
tended contact would freeze the flesh and
bones, until they could be broken up with
a hammer, a brittle stone would be
crushed.
Mr.. Tripler placed a rubber ball in q pan
/ of the liquir air and afterward threw it to
the floor. 1t broke into numerous pieces

a glass Of whisky was then exhibited and
some of the liquid air was poured into it,
and the combination stirred with a stick.
1t required but a few seconds to freeze the
whisky into stiff mass.

some one remarked.

The frozen whisky was passed about for
