IN THE ELECTRICAL WORLD.

-Lynchburg. Va, has new electric
street car line on which the cars have
just commenced running.
BY new device. pieces of metal
can be stamped with greater rapidity
by being first rendered plastic by an
electric current just before the stroke
Of the dies.
An incandescert electric light has
been SO arranged behind the transpar-
emit face OF clock that when a button
is pressed the position of the hands is
easily visible. This continuance, which
has the look of something practical,
is called by its inventor the Tempo
lux"
1t has been calculated that the cleo
tromotive force of bolt of lightning is
about $500, 600 volts, the current about
Ia, 900, 900 amperes, and the time to be
about leo, 600 part of a second. In such
bolt there is an energy of 2. 45O, 600, 600
watts, or S,2s4, 1s2 horse power.-Popu-

"A most singular relic was exhibit
ed at a meeting. at Calcutta, of the Ash
attic society of Bengal consisting of
piece of cable, the rubber covering of
which had been pierced by blade of
grass The piercing was so complete
and the contact with the copper core so
perfect that the efficiency of the cable
was destroyed.
"A German electrician, Herr Gull
cher has made a thermo-electric battery
giving a power equivalent to Los per
cent of the heat employed, and hopes
to exhibit at the Frankfort exposition
q battery which will yield at least s
per cent net effect With an econom-
zeal source of heat, this inventor be-
! lieves that his thermo-electric battery
will even excel the dynamo machine
In efficiency.
One of the latest applications of
electricity is that of machine for drill
ing holes in boilers in the sides of iron
vessels and in other places where iron
or steel is the material to be worked
upon. The machine has its own hold
ing-on magnets, and it may be swung
over the side of ship, or placed on the
surface of a boiler, where il will stick
without the necessity of clamping. The
convenience of such a device, adjusta-
BILE, as it is, by the mere switching off
or on of a current, is great, while it is
claimed the saving of labor resulting
from its use is considerable.
Thomas A. Edison says his idea of
producing a Shakespearian drama by
electricity is practically developed and
will be placed on the stage very soon.
| In the same general line is a new de-
vice, upon which he is now working, to
them gesticulate and talk like life. This
invention, he says, will do for the eye
what the monograph has done for the
ear, and with il will be combined the
principles of the photograph BY this
device the electrician will be able to
catch the gestures and expression of a
man or woman walking along the street
and reproduce them on canvas.
"A direct acting electric elevator is
among the latest electric novelties.
The motor is suspended beneath the
car, and is equivalent to about 80 horse
power, while the movements of the car
are easily controlled by switches. The
motor is connected with a system of
gear wheels, and they grip the rope on
each side and the car moves up and
down only when the motor is in mo-
ton. Should any accident happen to
the machinery, the gear wheels are au-
tomatically locked, and the car stops
In case of such an accident happening
while the elevator is between the
floors, the elevator boy may attach a
crank to the gear that extends inside of
the car, and the car can be wound up or
down until point is reached where the
passengers may alight without diff
