has been found possible. 1t is as divisi-
BILE under Edison's process as volume
of gas.
What of the Edison lamp? 1t can be
made at cost of twenty-five cents. In
its simplest form ii is as cheap as a gas
tip. 1t is plain glass globe, about the
size of small orange or large lemon.
In the bottom is fitted a metallic stopper
through which the copper wires pass,
and strip Of carbonized paper, shaped
like a horseshoe, connects the wires.
The air is exhausted in the globe. Turn
on the electricity, which is quite as sim
pie an operation as turning on gas, and
the carbon becomes and remains lumi-
nous, giving out a soft, brilliant, power
ful light, and the wick endures. No
limit has been found TO its endurance.
No matches are needed to strike light.
You touch the key and there is your il
Elimination. The glass globe does not
become heated. 1t grows warm, but by
no possibility can there be any combus-
tion. Break the glass, and the light is
instantly and utterly extinguishcd.
The moment the air enters the light is
out. 1t would be perfectly safe there
fore to use such light in powder
magazine. 1t will be of inestimable
value on shipboard. 1t can be employ
ed with the happiest results in mines
heretofore extra hazardous. 1t will by |
at once abolishing the use of matches in
our houses, and introducing light that |
neither heats nor enkindles, vastly re-
ducc the liabilities Of fires, and thus
speedily put down the rates of insurance.
This light wil@ do away with the neces-
sity Of heat in well lighted apartments.
One can produce dazzling illumina-
ton without changing the temperature.
As there is no combustion, there is no
smoke, so that this is the light long
sought for in picture galleries. Whcr-
ever wire can be stretched light may
be cheaply produced, so there will be
no excuse for dark alleys. This will be
a terror of burglars, for by the noiseless
touch of n key, not only an apartment,
but an entire house, may be instantly |
Hooded with light, to the terror and dis
Of all who seek darkness that
hey may do evil
1t isa light that does not hnrt the
Eyes and may be shaded and regulated
the Softness of the oil lamp
with the splcndor of the burning OF car
BON points.
The opinion is now entertained that
m entire city could be supplied with
electricity from single establishment.
New York, for instance, Is to be divided
nlo twelve districts, each receiving The
magical current from an independent
'entre. From four to six districts I'M
Ter this system would comprehend the
compact portion of Cincinnati.
Edison's flyorite theory on the sub
cct Is that the gas companies will be
glad to buy the right Of lighting under
Ms invention, aud that wires will be
conveyed through the gas-pipcs, the
lcw lamp being simply screwed on
where the gas tips are found. Very fine
insulated wire will suffice. All the APP
continents are simple.
Agents are already here for the pur-
,osc of introducing the Edison lamp.
l'hc object Is not to sell the right to in
liyiduals, but to employ capital in sup
dying districts. 1t is Edison's careful
'stimatc that the cost Of the electric
light, according to this system, will be
something less than one half the cost OF
'oal gus lie Is sure It will not exceed
hat figure. Beyond that he proposes
o use electricity as motor, to run sew
NC machines and the like, and has pre-
lared u meter for the exact measure
ncnt Of the electricity furnished to ench
rouse. We need not dwell upon the
Importance Of the discovery. II Il rev.
