In regard to this possibility, it may be
said that those who have care1uily lol-
lowed the electrical developments OF the
past few years, have come TO the conclu-
sion that it is rash 10 foretell that any
particular thing cannot be done by elec-
tricity. What such a reduc1ioh ms ~

of 80 per cent in the cost of lighting Tor

the city of New York would result IN a

WHAT NEW LIGHT WILL DO
In estimating the value of this new
form of light the fundamental basis OF
its suDeriority. its diffusiveneSs, must be
kept prominently in view heretofore
the tendency in lighting methods has
been TO cerate spots or biotcheS OF light,
which would brightly illuminate every
thing Within a certain radius. put leave

by changing the vacuum in the tubes, or
by changing the capacity of the circuit.
