Some recent experiments for deter
mining the velocity of sound give 1888

Pogson is making an atlas Of varia-
BILE stars in 1856 maps, which will con-
tain about 10000 stars.
The presence of sugar has been de-
tected in the petals of various flowers
in considerable quantity, varying from
seven to one per cent.
Soap bubbles or films have lately
been used by physicists as a means of
exhibiting the effects of tone vibrations,
giving beautiful and interesting ex-
periments.
Mr.. Proctor, the distinguished and
popular astronomer, maintains, in OPP
position to views recently published by
Vogel, that the larger planets are bodies
having q very high 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 been lately
rediscovered.
Under great pressure and at low
temperatures, physicists have at last
succeeded in reducing to a fluid state
all known gases. Pressures Of over
300 atmospheres are used, and tempera-
lures as low as 400 below zero.
Carbon is the name given to the pure
part of charcoal. 1t is present in al
most all combustible bodies and is it
self completely combustible. Carbon
is not decomposable, and therefore
ranks among the chemical elements.
Considerable advance has been made
in our knowledge of solar physics by
Henry Draper's discovery of oxygen in
the sun by means of the spectroscope,
this substance manifesting itself by
bright lines in the sun-spectrun,
Goal is nothing else than ferns,
MOSES and sea-weeds, petrifed beneath
the surface of water in the absence of
air. There are no less than $50 differ
ent species of plants petrifed into coal,
of which $50 at least are gigantic ferns.
It has been shown at the Dudley
Observation that the whole amount of
ammonia 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
with sea water and used in sea water
with large quantity of sand it may
take even twenty.four hours before
setting.
According to the academy, the Ger
man excavations at Pergamos have
come to an end, the Turkish firman
granted for the purpose having expired.
The last discoveries are statues OF Zeus
and Augustus, found near the Temple
of Augustus, which appears to date
from the time of Tiberius.
It is not true that special forms OF
food determine fat, That is an old ex-
ploded notion. Some organisms will
make fat, let them be fed on the leanest
and scantiest and least sacchsrine de-
scriptions Of food; whilst others Will not
be s'fattened," let them feed on the
most ''fattening'' of diets.
The history of chemistry is full of in
cident and interest. The name is de-
rived from the Arabic word chan,so,
signifying secret or hidden. 1t is very
ancient science, originating in the East.
The Egyptians were certainly well &C,
auainted with it. Indeed, they could
not have made their mummies without
its aid.
Single belts may be used with econo-
my as wide as twelve inches, but where
greater width is required they should be
of double thickness. All belts eight
inches wide and more are out of the
centre of the hide, lengthwise OF the
back; this is necessary to insure their
running straight.
