ACCORDING 10 1fOI. Dung, the density
of the sun is about one-quarter that OF
the earth, so the solar gravity is twenty
eight times greater than terrestrial
gravity.
100000 men were employed for
twenty years in building the great pyra-
mid at Ghizch, and ten years had been
previously spent in quarrying the stones
nd transporting them to the place.
A NEW community has been estab.
lished in Georgia under the title of the
"Eliiahites,n whose destructive social
principle is that their chief officer shall
hold one-fifth of their real property in
fee, and have control of all their cur
rent funds.
IL the examination of the bones col.
lected in the cave at Carlisle, Penn,
Prof. Baird found that all the species
represented have degenerated in size,
and this modern degeneracy ranges
from ten to twenty-five per cent.
AMONGST the novelties in agricultural
machinery is a locust or grasshopper
catcher, which, by means of an apron
extended in front, catches the creatures,
and passing them through rollers, re-
duces them to paste, which is dried,
broken up, and used fer poultry and
hog feed.
A New YORK chemist, by peculiar
process, now produces mu k from blood,
which cannot be distinguished from the
genuine article except by the absence
of the hairs generally found in the pro-

these, the microscope even fails to de-
tect any difference.
PROF. CozE thinks that the splntering
of bullets when suddenly arrested by a
hard substance, such as a bone or "a
piece of money, may be due TO the heat
developed by the sudden impact, and
not necessarily to the use of explosive
bullets.
DR.. A. HEwsoN, surgeon TO the Penn
sy,vania Hospital, recommends the
dried flowers of the May-weed, or wild
camomile, TO be scattered about "a
room TO rid it of flies. The same end
may be gained by throwing black pep.
per on hot shovel and carrying il
about the room.
PURE water will absorb many unpleas-
ant odors. A pan full of clean fresh
water from well or spring, placed in a
room which has been newly painted,
will absorb during the night so much OF
the smell Of the paint as to be totally
unfit TO drink. bowl OF water re-
naming in a close sleeping room will
always lmbibe very unpleasant flavor
In 1896 the Dutch explorers in Nova
Zembla built wooden hut. A fishing
expedition has recently discovered this
building. and in it one hundred and
fifty objects of interest, among other
things books which, after nearly three
hundred years, are in good state of
preservation. The collection is to be
placed in the Museum of Amsterdam.
THREE Austrians have patented a
process for conveying away, under
water, the smoke of river and ocean
steamboats,. 1t is said TO be a complete
success. The invention will greatly in.
crease the efficacy of submarine vessels,
while it will enable all ships of war to
do away with their most vulnerable
point-the funnel. Moreover, the
great danger of fire, arising from the
passage OF smoke-pipes through the
decks of steamers, will be entirely re-
moved.
The first scientific society was founded
by Baptista Porta in 1860. 1t was called
the Academy Of the Secrets of Ma
ture." The privacy of the meetings,
and the general belief that its members
employed the black art, led almost at
once to its dissolution by order of the
Pope.
If there is anything in nature that
possesses positive character it is light.
Yet the physicist may so reflect the
light from given sourse as to cause 1t
to destroy itself and produce darkness.
In like manner two sounds may be
made TO interfere with each other and
either produce silence or increased in
tensity of sound, at the will Of the OPP
orator.
ONE of the most marked of organic
differences between the sexes is that Of
muscular action. No one who carefully
watches the muscular acts of women
will fail to perceive a tendency to do
them with sort of rush, with super
abundance and sudden exertion of
force, rather than by the gradual appli
cation OF the precise amount by which
the end in view can be secured.
AN electric probe for the discovery of
foreign bodies in wounds was exhibited
by NJ. Trouve, at the last General As
sembly Of the Scientific Association of
France. The probe is hollow, and when
brought in contact with the foreign
substance the indicating apparatus is
passed through it. As soon as the latter
touches the object to be examined, the
vibrator of an electro.magnet is set in
operation, and by the character of its
vibrations the surgeon may determine
whether the foreign body is lead, iron,
or copper.
