Then after \ short interval large gobules or
it's lighter fluid would show disposition to dive
70 a heater depth but always returning TO the
surface again The dancing OF these spheres,
seen from the side was a fascinating spectacle
The air remained distinct from the water, and
did not mix as one might expect SO nearly the
same was the specific gravity OF the two that
only the most trihing change was necessary to
after the balance. And every now and then the
nlunges OF the upper element would go deeper
than before until finally, for second. the bot
tom OF the vessel was touched. The little masses
Of LIQUID air looked like glass alleys or jackson
balls. nearly an inch in diameter but coorieSs
They glittered like jewels. The increasing dem
sty OF the air. in consequence OF partial evapora-
ton as shown by this experiment. was attrlb-
uted by one Of the bystanders to the carbonic
acid gas in the atmosphere.
A copper tube having a thickness OF nearly
ouarter of an inch a diameter OF an inch and
half or two inches and length of ten inches
and omen only at one end was fastened upright

noured in a wooden plug was quickly driven into

A moment later there explosion like that
Of a small cannon and the plug smote the cell
ing violently. The warmth OF the metal had
yaporized the liquid, and great pressure
was thus de 'eloped.
Mercury poured into a mould frozen into
q solid block three inches long, an inch or more
thick and an inch wide. The threaded ends OF
two screw eyes were laid in place at the outset
co that p casting was made around them. One
screw eye was then caught over stout nail and
a weight of one hundred pounds or so was sus-
pended from the other. The mercury did not
Weld enough to let the weight fall for fifteen
minutes, and it did not all return to hquld
form again for more than half an hour
Tin dipped into a basin of boiling liquid air
and thus reduced to temperature of 800 below
zero became as brittle as glass Rubber treated
in the same way much hardened. but also
crumbled like stone under hammer. Copper.
leather and aluminium. however. retain Their
nexibility in spite of the extreme cold here util-

The method employed by Mr.. Tripler to reduce
air II a LIQUID form is original with him in some
respects. Although Linde Gin Germany and 9TH
crs have also adopted it, Mr. Tripler says that
he was the first to do So Various scientific men
have supposed that there was theoretical alb
suriity IN the explanation given by the New
York experimen'er but Mr. Tripler believes
he not only produces LIQUID air in larger guam
tiles but much more cheapy than foreign chem
lists he laughs at the sceptics He says that he
produces about ten or fifteen gallons of the fluid
with an expenditure Of about half a ton of coal.
one of the practical uses TO which this
derful stuff can be put is refrigerating. 1t is as
serted that a cold-storage system using liquid
air would be much cheaper thar IL operated by
ammonia I'm time. engines may be run with 1t,
perhaps 1t can be exploded, like gun cotton.
and used in cautery When once the various
other practical applications OF Mr.. Trplers
product are recognized it is possible that he may
figure as a benefactor Of mankind.
