The Electric Light.

L. II. johnson, Edson's assiataut fer |
the past eight years, gave an exhibition |
of some of Edison's inventions on Satur-
day night last b, fore the Teachers Asso-
citation of New York. An improved
phonograph astounded the audience by
the facility with which it recited pieces,
sang the "Star Spangled Banner" the
maid of Dundee" plantation songs,
etc. The telephone repeated loud enough
to be heard By the audience v hat hadbeen
spoken into beneath the stage. In conclu-
sion, Mr.. johnson spoke of the electric
light, and related many new facts con-
nected with it. He said
Mr.. Edison is man of wonde rful re-
sources. When he starts to experiment
he never follows in any rut made 10y any
body else, but always starts out on am IN
tirely different line. this week saw in
his laboratory the mechanism for genera
ting this current of electricity different
from that used by anybody else Mr..
| Edison is subdividing the electric light,
increasing the illumination and improy-
ing the mechanism for generating the
| current of ctricity. He expects to be
| able Ia place 600 lights in the circuit.
| He knows the subject thoroughly, and is
on the track of every Improvement in
the way. He will not have as much ex-
perimenting with this as he had with the
telephone. feel justified in saying that
vii hin less than one year from tonight
the electric light system of Mr.. Edison
will be in practical operation, not only
in the streets and pubic houses alone,
but in the private houses in New York
| city.
The editor of the London World de-
scribes as follows a visit to the London
Times office to see the working Of the
electric light in that establishment
| From gas light we merged suddenly
| into what seemed a flood of daylight,
which came from six small lamps placed
at Intervals round large room, in which
compositors and others were busy at
work. These lamps were suspended so
as to be raised and lowered at will. In
compliance with the wish of one of the
gentlemen present one of these lights, Sc
lected at hapbazard, was turned out by
means of tap, and IL remained out with
out the slightest perceptible increase in
the volume of light in the other lamps
Then another light at distance was
| treated IN similar manner, and with a
like result. These two were then relit
by turn of the tap the reverse way, and
turned on full power. Then was one
"slightly" lowered so as to give about a
third of its full hight, AZ with ordinary
gas. In short, we found there a useful
and agreeable light, which can be mod
Grated and arranged to suit all circum-
stances. This is the Rapleff light. | am
} no electrician, and shall not attempt to
give technical description of the ap-
paratus employed, but 1t seemed TO pos
sess great simplicity. NJ Rapieff says he
, can burn ten lights in one circuit; that
his carbons will burn for ten hours: that
they can be easily renewed, and withou,
| extinguishing the lights. He further @,
Inmates its comparative cost with gas a,
less than third.
