Some recent experiments for deter

feet per second.
pogson is making an atlas OF variable
stars in 1856 maps, which will contain
about 10000 stars,
The presence of sugar has been de-
tected in the petals of various flowers

Soap bubbles, or films, have lately
been used by physicists as means OF
exhibiting the effects of tone vibrations,
giving beautiful and interesting expert
mentS.
Mr.. Proctor, the distinguished and
popular astronomer maintains, in OPP
position 10 views recently published by
Vogel, that the larger planets are
bodies having avery light temperature.
The number of asteroids is now so
great that it is not surprising that one
or two are occasionally lost With the
aid of computation and very imperfect
elements, two or three have lately been
discovered.
Under great pressure and at low tenn
peratures, physicists have at last sue
ceeded in reducing to fluid state all
known gases. PreSsures Of over 800 at
mospheres are used, and temperatures
as low as l40 below zero.
The earth of grave yard in which
there had been no interments for at least
thirty years has been examined by DR..
Reichardt 1t gave off animal heat,

submitted to distillation.
Carbon is the name given TO the pure
part of charcoal. 1t is present in almost
all combustible bodies and is itself COM
pletely combustible. Carbon is not de-
composable, and therefore ranks among
the chemical elements.
Considerable advance has been made
in our knowledge of solar physics by
Henry Diapers discovery of oxygen in
the sun by means of the spectroscope,
the substance manifesting itself by
bright lines in the sun-spectrum.
Coal is nothing else than ferns, MOSES
and sea weeds, petrifed beneath the
surface of the water in the absence OF
air. There are no less than $50 diff
ferent species of plants petrified into
coal, of which $50 at least are gigantic
ferns.
1t has been shown at the Dudley OBJ
servatory that the whole amount of am
monia in six feet fall OF snow is little
over one-half pound to the acre, thus
proving that the beneficial effects of
snow are not due to the ammonia, as
supposed by some.
The best cement will harden in about
five or six minutes, and under water in
about an hour; when mixed with sand
it takes a little longer. When mixed
in sea water and used in sea water with
large quantity of sand it may take
even "a hours before setting.
According to the Academy, the Ger

Of Augustus, which appears to date from

The remains of large swimming and
flying bird, eXhumed from the London
clay near Sheppey, were recently de-
scribed before the Geological Society
Of London. 1t evidently belonged to
the same genius as the common alba
tross, but was considerably larger.
1t has been ascertained by soundings
that the roaring waves and the might
est billow of the ocean repose, not up
on hard and troubled beds, but upon
cushions Of still water; that everywhere
at the bottom of the deep sea, the solid
ribs Of the earth are protected as with
q garment, from the abrading action
of its currents; that the cradle of its
restless waves is lined by a stratum of
water at rest, that it can neither wear
nor move the lightest bit Of drift-stufr
that once lodges there.
