Curious, Useful and Suggestive.

An omnibus propelled by steam
has been used in the streets of Edin-
burgh, with satisfactory results.
Pacto-engraving, though far from
perfection, is fast developing as an
art, and inaugurates a revolution in
printing.
Mining engineers have been stim-
ulated by the late disasters in mines
to invent plan of extingnishing fires
with carbonic acid gas.
Corrugated shell fish, living at vast
depths in the sea, sustain pressure
of 500 to 1000 pounds to the square
inch without feeling it.
In periods Of the past a greater heat
pervaded the earth than at the pres
ent time. The fora and fauna of a
tropical climate fourished at the
poles,
The old question whether or not
those nebul@ which appear in pow
erful telescope as collections Of stars
are really ornaments, like our own
milky way" is actively discussed
again.
The extraction of air by heated
shaft gives, by the fireplace, in a
room of moderate size, excellent VEN
tilation. The same plan on a great
scale, has been earnestly advocated
by many writers, and particularly
by General NORM in France.
The Oxyhydric (Drummond) light
can now be procured from oxygen
gas and super carburretted hydrogen
without the aid of lime, carbonic, or
zircon pencils. Its great recommen-
dations are it's brilliancy and cheap
ness, the cost being only three cents
a week, at the rate of five hours each
of the seven nights.
A startling question is raised !:
whether some of the nitro glyoer-
inc used in torpedoing oil wells does
not become mingled with the oil
itself, and may not, in consequence,
produce dangerous explosions
Though no accidents from this cause
have yet been recorded, it would be
we'll for refners to be on their
guard.
Tightening struck and melted
gun-barrel. A careless inspection of
the solved metal suggested a thought
and that in turn begat another, un-
til the final result was the discovery
of the manufacture of steel by the
means of electricity, for which the
discoverer holds letters patent from
the Government of the United States
and which will be among the most
important discoveries Of the age.
To gild silver silk thread, gold or
silver leaf is rubbed on stone like
paint--honey beiugthe best substance
to moisten it-until reduced to fine
powder. The silk thread is soaked
or hoiled in solution of chloride of
zinc, and, after being washed. it is
boiled in water with which the gold
or silver powder has been mixed
when washed and dried, it will be
found coated with a fine layer of gold
or silver which may even be polished
in the usual manner. This method
has been patented in England.
The sentient matter of brain and
nerve is composed of brown material
called ganglionic, which might be
compared TO galganic battery, and
white fibrous mate rial, which might
be compared to the telegraphic wire.
On each end of these 1900 fibers of
Corti's organ in the ear is a ganglion
and it acts on the fiber just as the
battery acts or the electric wire, or
the fork upon the cord. With 5000
ganglia and cords, then, every audi
Bile sound in nature can be reproduced
in the mind.
Photography has been brought to
such perfection that even the bowels
of the earth yield to it their myster-
les, and Broadway has proved no ex-
ception. Pictures have been taken
of the Pneumatic tunnel with the en-
tire travel of the street, omnibus,
carts, carriages and steam fire en-
gines, all trotting directly over the
head OF the artist. Artificial light
was employed, in TIE use of which
the photographers have been very
successful. The illumination was OBJ
tanned by means of two large and
powerful oxyhytrogen calcium lights.
