ELECTRICAL SCIENCE.
The Farthest Step Toward Natural

most interesting novelty at the Electrical

scientist. NJ Claude, which toward the

Great Yellow Way.
The apparatus was brought to New
York for exhibition before a private
scientific conference. But the managers
of the Electrical Show took the tubes,
still held in bond-appArently there is a
tariff barrier against them-to indicate
the farthest toward natural light that
artificial light has, through electricity
accomplished. These tubes are five in
number, 16 feet long. 1t requires 5000
volts to operate them instead of the ITO
volts necessary for the ordinary mean

The two outside glass tubes grow an in
tense orange. The three inner tubes
of the gridiron grow green, like the Pc
ter Cooper Hewitt tubes used in printing
offices and composing rooms and photo
graph studios, the rays of which absorb
the reds and yellows of all objects they
ilumne. The orange Cor Yellow rays
of the Claude tubes combining with the
green rays of the green tubes produce

NJ. Claude calls the orange-yellow
tubes the mean tubes, and the green
ones are mercury tubes. Ne" meaning

he had to find a name for the birth of a
new day. The light shed is not so asser-
tive as the Hewitt-one is almost uncon-
seious of it, as of something normal and
artess.
Another novelty of the show is of
American invention. 1t is the new and
not yet entirely perfected nitrogen lamp
the one which, If your tungsten lamp
now, say. costs you $12 for current, will
reduce your expense to IS. 1t will cut
the cost of tungsten lighting one-half,
and the Edison Company declares that
they hope to make up the difference by
the added sale of new heating. cooking.
power and other appliances. They are
willing to install it. since they foresee
no loss eventually in revenue from cur
rent consumed, and indeed expect to
equalize the load which. now bears
heaviest at night, economizing thus in
production.
The new lamp is tungsten lamp of
high efficiency with the lamp fiaments
set in nitrogen gas instead of In vacuum.
Putting it simply. the new lamp is a nj
trogen-filed incandescent using a tung-
stem filament
1T has not been SO many years ago
since the consumers of electricity were
smiling over the fact that the tungsten
lamps would give them three times as
much light for the same amount of cur
rent as the carbon bulb consumed. The
new nitro bids fair to cut the tung-
stem consumption almost in half de-
clares the Edison Company.
"The first nitrogen lamps will be put
on the market in about six months.
They will be large and suitable for out
door illumination. The new lamp gives
light whittier than the ordinary tungsten
and comes near daylight The new
lamps at the electrical show are four
monster globes rated at 5000 candle power,
suspended from the four corners of the
big central hall. These lights are turned
on for five minutes at stated intervale
every day. This system has been adop-
ted lest the blaze dazzle the eyes of be-
holders, making it impossible for them
to see anything else"
1t should be a fine system for the white
way.
The United States Government initiates
visitors into the processes of money
making. A fully equipped mint-a small
duplicate of the great plant at Philadel-
phia, which sight-eers must examine
from a distance of 40 feet-has been con-
structed and brought direct to the on
locker. Coin manufacture is shown at
