IN THE ELECTRICAL WORLD.

The electrical building is the first
OF the exposition buildings at Atlanta,
Ga, to be completed.
There are now $50 electric railway
companies in the United States, oper.
ating 5000 miles of track, $4,000 cars
and having an invested capital of $780,.
100000.
Electric lights will probably soon
be authorized in the churches of Rome
for illuminating purposes, though wax
candles and oil lamps must be retained
for the use OF the altars and shrines.
The Brockport, N. Y, electric light
plant has been equipped with auto
matte sprinklers in the boiler room,
and all wires in the dynamo room will
be run in porcelain tubing under the
floor.
When the cable between Scotland
and the Isle Of Null broke recently
communication was kept up without d
wire by induction. The distance is two
miles, and the telegraph wires along
the island coast were paralleled on the
mainland.
1T is said that "the rays of the arc
light have decided therapeutic value
and that the arc unprotected by glass
globe is very useful disinfecting
agent It is asserted that bad odors
are dissipated by the direct rays, and
that real purifying action has been
frequently observed.
"A vibrating helmet for the cure Of
nervous. headaches has been devised by
d French physician. It Is constructed
Of strips of steel, put In vibration by a
small electric motor, which makes six
hundred turns a minute. The sensa-
tion, which is described as not un-
pleasant, produces drowsiness; the pa
tient falls asleep under its influence,
and awakes to find that the pain had
ceased.
"A new primary cell has recently
been described, which is said to be the
most powerful cell known. 1t consists
OF plate of metallic magnesium in .
solution of ammonium chloride, and a
plate of copper in a solution of cupric
chloride and hydrocholoric acid. The
electromotive force of this cell is given
as three volts, and it's internal resis-
tance is quite low. The current is said
to be constant for long periods.
The housewives summer friend, the
gas stove, has rival in the form of an
electric cooking apparatus. Cheap
hess, GOODNESS, evetiness and speed are
some of the attributes claimed for it.
1t may be used in any house which is
wired for incandescent lights'and there
are those who maintain that its use
makes July roasting of beef de-
light and August ironing a refresh-
ment. 1t has been estimated that it
costs about seven cents an hour to
keep it going.
lin further confirm alton of the sue
cessful experiments concluded last
year in England in transmitting tele-
graphic messages over long distances
without wires, an account has been re-
ceived from Scotland of the mainte-
nance of telegraphic communication
by means of the same system between
the island of Null and the mainland.
The six mile cable which usually kept
the islanders in touch with the outer
world had broken down, and they were
uncertain as to how long the inter-
ruption Of the communication would
last. A local electrician, who had
heard of Mr.. Preece's plan, saw no
reason why it should not operate at
Oban just as we'll as anywhere else,
and lost no time In running gutta'
percha insulated wire, ~ miles long.
along the ground from Movern, is
miles from Oban, and signaling through
that; while on the island of Null the
ordinary overhead circuit connecting
two distant villages was made use Of.
The distance intervening between tho
two parallel circuits was about az
miles A vibrator was used as trans.
mitter and telephone as receiver,
and the usual telegraphic traffic was
carried on until the cable was repaired.
