"A new claimant for the invention
Of the telephone has appeared, and M.
lc Comte du Moncel supports him. So
early rs 1854 Charles Borsoul, French
man, is reputed to have invented the
telephone substantially as II is now, and
published his discovery in the autumn
of the year ment 'oned.
The speed at which explosions can
travel has been looked into by NJ Ber-
thelot. He took for the gasses carbonic
oxide and oxygen, and these he ex-
plodcd in a tube sixteen inches long and
one-third inch in diameter by means of
electricity. The rate observed was the
Unexpectedly high one of $500 metres
a second.
The introduction of electricity as a
substitute for lamps and candles on
board ship is making rapid progress.
There is one source of safety in this TO
the ship and the passengers. All lights
are put out at eleven o'clock. After
this time people may talk in the dark.
but there is no possibility of the reck-
less use of lights and lamps. - Chicago

"A simple and useful bolt has been
invented by Mr.. Arnott, of the Lyceum
Iheater (London), having for its object
the fastening Of doors of theaters and
other public buildings, so that they can
be opened by mere pressure against the
door from the inside, and not at all from
the outside, dispensing with all other
fastenings, which cause so many acci-
dents in eases of panic. One advantage
is, that being once unfastened il can not
be reboltcd by accident.
1t was reported a short time aco
that piles had been driven by dynamite
in some German experiments. Later
advices concerning The process state
that an iron plate sixteen inches in di-
ameter and five inches thick is placed
on the top of the pile to be driven, and
upon this plate pound-and-a-half
charge of dynamite is exploded by cleo
tricity. The force of the explosion
drives the pile into the mud as far as
would five blows struck by a weight of
$3.50 pounds falling from height OF
ten feet, The system was originated by
Herr Pradamovic, City Engineer Of
Pesth.
"A Bridgeport Comm man has pro-
duced an invention so dangerous that
the Government refused him q patent
on it. The description tells of hollow
steel belt filled with compressed air
from an air pump, and which can be
worn so that it is completely concealed,
with the exception of a tiny nipple pro-
truding through a vest buttonhole; n
pellet of condensed poison placed in this
nipple can be noiselessly sent, with
force sufficient TO penetrate q quarter
inch of rawhide, a distance of forty
feet; and if the pellet penetrates the hui
man skin, in fifteen minutes death en-
sues, although the first indications OF |
do not appear under five min
utes. boston Post
