said Mr.. Tripler.
He poured mercury from a bottle in
to a paper box, and for a couple Of
minutes subjected II to the cold Of the
liquid air. He had placed Il handle in

ICE MADE OVER A FIRE.
The experiment of making ice over a
] fire was perhaps the most strikinGly IL
p Illustrative of the power Of liquid air.
Mr. Tripler took a kettle, filed 1t with
the liquid and it began TO boil. He
placed it on a gas stove so that the
liame could play on the bottom of the
r vessel The heat but intensified the
y cold, as it accelerated the liquid in
turning into gas. Ice water poured in
to this kettle still further increased the

stream of steam aloft to a distance OF
, six or eight feet. No hOusekeeper has
ever seen her kettle boil so. All this
time the water was being frozen within
