draws the conclusion that man has within
him all the elements from which the uni

When heated and tested with SprengePs
aspirator, this iron gave off three times it's
volume of hydrogen. And since malleable
iron can only be-made to take up about
one half its volume of hydrogen, Mr. Gra-
ham understood the. message to be that the
iron had cone fiona very dense atnos-'

= An enormous balloon confined by
cable which unwinds from a drum, is to
make hourly ascensions from the middle of
the Exhibition, carrying up twenty or
twenty five persons to hight of three or
four hundred feet. 1t is to be supplied
with hydrogen from the decomposition of
water by red hot charcoal, at a cost not
over $275 per 1000 feet. The balloon is
reported to be perfect sphere of a gdiamL

mented together with several coats of Ca
outchouc Varnish and covered with linseed
oil. 1t is calculated that the vast ascen-
sional power will resist material DETECTION

is Mr.. Henry Giffard, the inventor of the
injector.
"A patent has just been granted to d.
W. S. Rawson, of Peru, Ill, for a novel
method of multiplying photographs The
invention consists In placing a box, con
tanning number of small, mirrors, each,
about one inch square, in front of the sub
iect, so adjusted as to reflect as many ina
ges into the camera as there are mirrors
used. From four to twenty five small 3or-
traits are thus made at once, with the lGa,i-
mon single camera, as clear and sharp az
by direct light. From twenty-fi to one
hundred small copies of engravings drug
gists' labels, new styles of hats and bonnets,
or any design for business cards, for which
are now used, may be made
on one negative plate, and printed from at
a corresponding rapid rate. The specimens
cannot be distinguished from those made
in the usual way:

be going the rounds widely, showing how
petroleum can be and has been used for

triumph only equaled by that

hair of his head We can only say that
the use of petroleum as fuel in domestic

purposes has, demonstrated the fact that
none of its advantages compensate for the
internal stencil incident to its combustion.
Sea sickness is prevalent enough already,
but its rayages will be multiplied ten-fo1d,

TO the Odor of bilge water is added the pun
gent perfume of bouquet de Kerosene. Such
vessels will find their traffic limited mainly
to freight, for passengers will avoid all
craft pervaded by the aroma in question.
1t is related as singular instance of
ignorance in our own resources in naval
warfare, that while the Monitors 15-inch
guns were used originally with only thirty
five pounds of powder, since the war a
charge. of one hundred pounds has been
safelyused; while at the recent trialo the /
20aneh gun at Fort Hamilton, the charges
were gradually raised from one hundred
and twenty FIVE pounds of mammoth grain
powder at the first shot to two hundred
bounds at the fourth shot 1T was only
short time since that it was considered
quite feat when hundred pounds We're
fire in 20inch gun, in an experiment in
New York harbor, although the charge
was so smallin proportion to the bore that
the artillerists had to ram it in with a
cushion of hay to bring it up to the vent.
With the kno Wedge of the real power Of
the gun, our means Of den1olishing enc

1t is certain that a ball weighing 1880
pounds, propelled by the explosive force
Of two hundred pounds of powder, is sure
to make the splinters fly wherever it hits.
Few incidents of scientific interest
have ever excited more general interest
than the experiment devised by NJ, Foucault
Of Paris, in 1851, for demonstrating the
rotation of the earth by means of pendu-
lum and making this rotation visible to the
eye of an observer. His mode OF pro-
cedure was as follows; From the center of
the dome of the Pantheon was hung fine
wire 81 10 feet Ions. Terminated by q heavy
ball. the Whole swinging freely as aSpendt-
hum. Beneath the ball was placed round
table Now it can be shown by the princi-
in motion, will not change the direction of
it's oscillation, however the point of sup
port may be rotated; so that in this case the
diurnal revolution of the earth will not at.
feet the plane Of vibration, but the latter
will maintain strictly the same direction
during the twenty-four hours. In this
interval, however, the table, in conse-
quence of this diurnal motion will con-
tinually change its position SO as to makea
comp lete revolution around its center AS
d consequence it will soon be found that
the ball Of the pendulum never returns pre-
eisely to the same starting point after two
vibrations, and line marked by
a projecting point of the balls upon the
table, will show the kearth's rotation. IF
the experiment were tried at either pole, a
complete apparent revolution would be
seen every twenty -four hours. At the
equator, OF the other hand, the plane of
vibration is carried forward by the revolu-
ton of the earth and so undergoes no
change with reference to the meridians.
Between these localities the time required
