10 most extraordinary exhibit ever
In Washington was witnessed q
Arlington hotel a few nights ago
The scientific circle Of the city.
piers Of the Cabinet, Supreme
ft, diplomatic csrps and other pub
men. 1t was given under the aus
OF the National Geographical So
4, presided over by Professors Bell.
Inventor Of the telephone, and fur.
ed an opportunity for Charles p.
ler OF New York to. show for the
time In public the new motive
pr which he has discovered ai1d
liquid air. A description OF this
erkable duid and Its uses. appears
cClure's Magazine for March, and
Dre elaborate account II given in
April Century.
ieny and simply stated, Mr.. Trip
lakes 800 gallons Of ordinary air.
IN from any window, and by com.
sion and cold reduces II TO one
bn OF a liquid that looks like gly-
pc and retains Its form at a tenn
ture Of 312 degrees below zero.
warns 1t expands into vapor and
into air, just as water Is expand
nto steam by lleat. BY controlling
expansion Mr.. Tripler proposes to
lish a new motive power for the
Of transportation companies ON sen
land, for factories. furnaces and
every other purpose for which
m and electicity are now used. The
ansive force IL equal to 1900
nds n square INCH, and without an
aust pipe the pressure In NO great
there IL now no material Of SUM-
strength to restrain 1t. In other
ns, pint or a quart or a gallon of
liquid will burst any vessel In
ch II may bc confined unless there
u opportunity for Its gradual es-
quid air is manufactured by ap-
titus which Mr.. rripler has invent
The first gallon or two Is made by
use Of coal or any other ordinary
just as ne is made In a factory.
thereafter he is able to reproduce
gallons Of the fluid by the expendi-
, OF two. A railway locomotive or
enmship will, therefore, create Its
power from the atmosphere ms It
PES along its why. and n factory
1neer will simply turn the key OF n
tilation pipe, start his machine and
nufacture fuel ms he needs 1t. Mr..
)pler insists that this energy can be
ID with no more difficulty and at a
d 20 per cent. less than steam, and.
Flng mastered the secret Of Its pro-
Elton, he now proposes to apply 1t
practical use.
|Gr. Tripler brought six gallons Of
Hiid air with him from New York,
. In the presence Of four or FIVE hum
persons performed the experiments
et are described In McClure's Maya
)e. He dipped the stun out Of his
with an ordinary tin dipper, Just
= milkman would dip milk. He
bpped potato In II, lifted II out In
% or three minutes and threw Il on
: floor, where II broke into q thou
nd little crystals. He took . rubber
u, immersed II In the liquid and
Pm broke It as II II. was glass. He
Dpped In q piece Of beefsteak and in
moment II was broken into little
ngments that looked like petr1aed
pOd. He Immersed tumbler Of al
Dol, and In n few minutes Il was
zen Into = block OF Ice. He nlled .
eteboarti box with mercury, which
zen immersed In the liquid air be-
me ~ hard as steel, and be used It
hammer to drive nails in the to
!. He immersed copper, tin. iron and
'ips Of steel in the liquid air, and
~ crumbled like piecruxt. He DEM
strated the expansive power Of the
Iuid In similar manner. and alto
ther performed experiments that
re not only novel but amazing. 3
