Ice will reach lower temperature
/ than 80 degrees If the temperature Of
the air is less than that. 1t will take
| practically the temperature Of the at
mosphere.
Liquid hydrogen is transparent, and
the lightest as well as the coldest liquid
known, a cork sinking in it like lead.
A whitish substance seen at the bottom
of the vessel ON Prof. Dewar's first ex-
hibition was really solid air or air ice.
The multiplication Of new compounds
in organic chemistry is something ap-
palling. In 1883 the total number of
carbon compounds recorded was 10000,
but newly revised list by DR.. M. M.
Richter enumerates not less than
67 1000. and the end seems yet far off!
A Canadian engineer has invented a
foghorn In which the noise is produced
by half a dozen clappers striking a
gong and actuated by electromagnetic.
A dynamo, supplied with power by
naphtha engine. furnishes the current.
About 600 strokes per second fall upon
the gong, thus producing practically
continuous sound, and this is magnified
and governed In direction by a mega
phone. A small model of the horn is
said to have made itself audible at q
distance Of two miles.
Recent investigation Of the old prob
lem of the diffusion of tin over eastern
Europe and Asia Minor In prehistoric
times, leads to the conclusion that
about thousand years before Christ
the tin Of the British Isles was carried
overland to the Aegean Sea. The in
vention of the anchor led about 2,7OO
years ago to, the opening of a marine
route between England and the eastern
end of the Mediterranean, and then the
Phrygians controlled the tin trade with
their ships. The short summer nights
Of North Britain were among the won
ders that Greeks talked of in the days
Of Homer.
According to the recent studies of
Signor De Sanctic, of Turin, children
begin to dream before their fourth year,
but are unable to recall dreams before
the age of or 5. This age, he con-
cludes, is that at which child first be-
comes distinctly conscious Of self.
Aged people dream less frequently and
less vividly than the young. Women's
dreams are more frequent, more vivid
and better remembered than those of
men. Criminals and delinquents dream
much less frequently and much less
vividly than other people. Two-thirds
of the most depraved criminals exam
ined by Signor De Sanctis were never
conscious Of dreaming. This is ascribed
to lack Of mental activity.
Studies of the planet Jupiter during
the opposition of 1899 have afforded
some new figures concerning its rate,
or rather rates. Of rotation. These fig
ures do not affect the round numbers
in which the equatorial velocity Of Ju-
pliers rotation is usually stated, viz,
about 2S,OO0 miles per houh. But they
furnish additional proof that the mo-
tions visible on the great planets sur
face are not uniform from year to year.
Since the spring Of 1897 the equatorial
region appears to have experienced an
acceleration of velocity. Relatively to
the surface some 80 degrees north or
south, Jupiter's equator rushes ahead
with hurricane speed. between 200 and
800 miles an hour-in itself sufficient
indication that what telescopes show of
Jupiter is not a solid crust but layers
and masses of restless vapors.
