WONDERFUL AERINE.
BONE OF TIE REMARKABLE PROPER
TIES or LlOuEFlED AIR.


portance of the Discovery of Aerine.
look upon the commercial produc-
tion of aerine as very important dis
covery, and / think the future question
of economy in motive power Is init
mately associated with this liquid.
Compressed air. at pressures ranging
from 900 pounds upward, is conduct
ed from an air receiver through small
pipe, is refrigerated to expel its mois-
ture and is then conducted into the APP
paratus, which liquefies it completely
without the use of chemicals of any
kind, and it flows from this apparatus
in stream about the size of lead
pencil Tin the apparatus which i saw
into glass insulated receptacle, con
tanning about two gallons. | saw this
receptacle filled in very short time.
OF course, being in an open vessel, aerine
has no pressure, but its temperature is
approximately-3S5 degrees f., or 445
degrees below the atmosphere at 90 de-
grees +.
Inasmuch az it is boiling rapidly on
the surface, owing to its absorption of
heat from the atmosphere, it looks like
carbonated milk, but upon dipping some
of it out in a glass and observing its
color through the glass, it has very
much the appearance of ordinary water
and about the same weight Its temper
AZURE is very deceptive for as it runs
from the condenser one may allow it to
trickle over the fingers for short space
of time, and it appears to have the at
mospheric temperature. The truth,
however, of the matter is that it does
not come in contact with the fingers at
all. The hand being somewhat like $50
degrees warmer than the liquid, it
throws the liquid into a spheroidal state
and interposes between it and the finger
film of atmospheric air.
The sensation is very much like push
ing ones hand into "a bag of feathers or
into mercury bath. allowing, of course,
for the difference in weight between
the mercury and the aerine. If, how
ever, you immersed your hand in the
liquid "a sufficient time to establish a
contact, the flesh would be burned the
same as if it We're exposed to 440 de-
grees Of heat, measured above the at
mospheric temperature. If a test tube
of y inches diameter, having a cou-
pie of pounds Of mercury in the bottom,
is immersed in aerine, the mercury
will be frozen solid in few seconds
and may be hammered out and other
wise manipulated the same AS lead An
alcohol thermometer of large size will
be frozen instantly upon being i'm
mersed III the liquid.
An idea of the tremendously low
range of temperature may be gathered
from the fact that it will take several
minutes to thaw out the small bulb Of
this thermometer by covering it with
the palm of the hand.
A tablespoonful Of aerine poured on
about fluid ounce of whisky will
freeze it at once into fat scales, giving
the whole the appearance and color Of
cyanide of potassium. This may be
emptied out OH table and will remain
frozen in that condition for fully five
minutes
A teacupful of aerine poured Oh top
of a tank of cold water goes into its
spheroidal state instantly in globules of
about half the size of an ordinary mar
BILE, which fly around on the surface,
leaving trail of white vapor behind
them.
A handkerchief of either silk, linen
or cotton saturated with the liquid will
be charred and destroyed just the same
as if it were put in an oven and brown
ed, though no change of color is appar-
ent. Its evaporation is quite slow, and
IL may be carried about for "a number Of
hours in an open vessel without entire
ly disappearing. 1t probably represents
compression Of about 700 atmospheres,
and would, therefore, in confined
space and at 80 degrees temperature,
represent pressure of somewhere from
10000 to IL, 200 pounds to the square
inch.
OF course it is rather disappointing
to have our ideas of absolute zero COM
pletely upset. While we have always
appreciated the fact that it was pure
ly theoretical conception, and while it
was perfectly possible to think of a
point where air would have no pressure,
it was not possible to think Of its hav-
ing no volume. Still, not being able to
prove to the contrary, we have accepted
the absolute zero as possible reality.
OF course this has all been based upon
the proposition that air was perma-
nent gas. In experiments, however, of
the kind that l have just alluded to, we
find that at temperature of 1856 air
changes its physical state, yields up its
latent heat and becomes liquid, bring
ing into play new series of phenom-
tna which are not at all consistent with
the equations which we have depended
upon. AT about -425 it becomes sol
id, after which we know of no means of
further changing its state, so that
-46l, the absolute zero, is an impossi-
bility both in conception and realiza.
