WHAT MAKES Com POP Did Won
ever have it explained to you why it is
that corn pops when you place Il over
burning coal OF on hot stove? Indian
corn, so the chemists tell us. contains all
the way from six to eleven parts in 100,
BY weight, of fat. By proper means
this fat can be separated from the grain.
and it is then q thick, pale oil, When
oils are heated sufficiently in closed YES
sells, SO that the air cannot get to them,
they are turned into gas, which occupies
many times the bulk the oil did. When
popcorn is gradually heated, and made
30 hot that the oil inside of the kernels
turns to gas, this gas cannot escape
through the hull Of the kernels, but
when the interior pressure gets strong
enough it bursts the grain. and the exo
plosion is 80 violent that it skaters it
IN the most curious manner. TIE starch
in the grain becomes cooked, and takes
up great deal more space than it did
before.
JUPITER. --Jupiter's diameter is about
eleven times that of our earth, and his
mean density is about quarter that of
theearth, or abouta third more than water.
Now, bulky body may be composed of
heavy materials, and still, as a whole.
be light, like an iron ship or lump of
pumice-stone, that will float in water.
The pumice lump is light on account of
its vascular formation, so that the mass
consists of heavy felspathic material and
the air it contains. Extract the air. and
the pnmice loses it's floating power.
though still far from heavy in proper
ton to its bulk. Most of the earth's
crust is formed of solids much heavier
than water. GRANTEES are more than
two and half times heavier than water.
slaty rocks about the same, and SO are
ordinary lmestones, the variations of all
being from about 2.5 to 80. The IRON
stone group contains denser minerals
red hematite has a specific gravity of As;
magnetic ironstone, As to 8. 2, etc., and
many other ores are heavy. At some
remote period, when only part of the
now solid earth had been condensed
from gaseous and vapory matter, our
planet might have had q mean density
like that Of Jupiter, as its rocky nlateri-
ais contain between 40 and 80 per cent.

chemical combinations were going on
rapidly our globe must have been the
scene of
ThunderH, hshtnings and predigious storms.
And it is probable that certain stars
which have suddenly blazed forth with
passing splendor have exhibited to us
the spectacle Of CONGREGATIONS extending
over millions and billions of square
miles. Color-changes in Jupiter-such
as those noticed by Mr.. Browning and
caused by soda flames, though not fierce

is estimated as always exceeding, though
not in very high degree, what it would
