Most physicists think that the
sun radiates heat as it does
light or as a stove emits warmth.
The horn of the rhinoceros is
not joined to the bone Of the head,
but grows on the skin like a wart
or corn.
Microscopists say that the
strongest microscopes do not, prob
ably, reveal the lowest stages of
animal life.
Man is scientifically defined
as forty-five pounds of carbon and
nitrogen diffused through five
buckets of water
1t is now claimed that foods
stored in an atmosphere Of carbon
lie acid gas are preserved indefi-
nitely, the freshness and flavor be-
ing retained better than by the
use Of dangerous antiseptics or Of
ice.
An eminent scientist suggests
that the twinkling of the fixed
stars may actually be caused by
the flaming of the tremendous con-
flagrations possibly taking place
on these far-away and distant suns.
The electric current is being
utilized to hasten the process of
tanning. Leather which took near
ly year to tan by the old process
can now, it is claimed, be tanned
in three to six weeks or less by
aid of electricity.
Ferrel, high authority, believes
that upper air currents, proceed
ing from the equator to the pole
and produced by the heat in the
tropical regions, are defeated by
the rotation Of the earth so as to
flow almost easterly in certain lat
itudes.
The greatest depth, writes Prof.
Seeley in his "Story of the EARTH"
at which earthquakes are known
to originate is about thirty miles.
1t has also been calculated that a
heat sufficient to melt granite
might occur at about the same
depth.
The difference i'll the length of
the cables in the East River
Bridge, Brooklyn, when the Their
mometer registers zero and when it
registers 100 degrees above, is two
feet four inches. The difference
In the rope which hauls the cars
is seven feet six inches.
Photography has lately deter
mined the depths to which the
suns rays can penetrate through
water and the result is that at
depth of 553 feet the darkness
was about equal to an exposure on
a clear but moonless night. The
exposed plates at this depth gave
no evidence of light action.
1t is a we'll known fact that
horses can sometimes perceive
sounds which are inaudible to hu-
man beings. Seventy-two hours
previous to the recent earthquake
In the Italian Riviera, the horses
of that region began to be very
restless, showing that they were
sensible thus early Of subterranean
noises unheard by the inhabitants
until a few moments before the
first shock.
In temperate regions the con-
ditions under which ponds and
lakes freeze over at the beginning
Of winter are all favorable to the
forming of smooth ice. The cold
is most intense in the perfectly
still nights Of that season when
ice is first formed. Again, the
water freezes at a higher tempera-
ture when smooth than when dis
turbed. The consequence is that
the ice on our lakes is smooth.
Such is not everywhere the case.
In Siberia the first freezing cold
often comes attended by violent
winds.
1t is said that DR.. Carver, of St.
Augustine, Fla, is living in the
oldest house in the United States.
1t was built in 1862, and was oc-
cupied by Spanish monks before
st. Augustine was founded. In
the house DR.. Carver has sur
rounded himself with a collection
of antiquities connected with the
history of Florida and the Spanish,
who once ruled it, that is of itself |
