"A powerful electric light is to be
placed on the summit of Mount Snow
don in Wales. where it will be visible
not only over n great part of Wales and
England. but far over Ireland also.
Among the interesting exhibits at
the Frankfort electrical exhibition was
that of a coach and sleigh having in
candescent lamps ut the end of the
tongue and in the lamp-holders ut the
sides. The storage battery is placed
beneath the drivers seat
The following metals will conduct
electricity in the following proportions.
viz: Silver. 100; copper. 90; gold, -;
aluminium, 50; zine, 90; platinum, 10:
iron, Ia; nickel. IL; tin. II; lead. :. OF
the above, copper and iron have the
greatest commercial value as electric
conductors.
"A novel portable electric lamp has
been invented which finds a great de-
mand in mines and for the use of fire.

burns several hours, can be readily
charged, is light. handy and compare
lively inexpensive.
AT the Frankfort electrical cxhibi-
ton there was an interesting feature
in the shape of series of arc lamps
supported on n revolving drum. The
lamps are kept burning in spite of the
movement, and the device is said to be-
valuable especially for steamboats,, To-
comotives and lighthouses
Prof. Elihu Thomson corrects tho
popular impression that luminosity of
arc lamps is due to heated carbon
PARTICLES. He says that, although there
| is steady stream OF carbon vapor be-
tween the carbons, yet the light is
nearly all derived from the enormously
heated surfaces from which the evap-
| GRAFTON takes place.
Another link in the chain of sub
marine cables round the coast of Gen.
| trail and South America has been estab-
lished by the completion of the system
of the Societe Franchise des Telegraphs
| Sous-Marins between the West Indies
and Brazil This places the United
States and Brazil in closer telegraphic
communication than they have been
before. Electrical Review
| The theory of the light of the au-
| rora borealis was evolved from the
analysis of its light by the spectroscope,
| which showed that it was caused by
electrical discharges among the parti-
| cles OF meteoric dust in the atmosphere.
The broad red line of the spectrum of
iron is shown in all these cases, and
thus upholds the theory, rs it is well
known that the principal part of mete-
ors is metallic iron.
An inventor proposes to aereate
waters by passing an electric current
through them. There is no doubt that
this can be done. but stomach-full of
such n mixture is too suggestive of dy-
Mantle to permit of its general adoption
as beverage. Already a number of
plans have been proposed for ageing
liquors and some have been tried with
more or less success
Carl Herring, special correspondent
OF the Electrical World, writes to that
paper from Frankfort, Germany. the fol-
lowing important intelligence regard
ing the long distance transmission of
electric power: THE long distance
high tension transmission plant be-
| bWcch Lauren on the NeC<ar and
Frankfort has been successfully tried.
Two hundred horse power utilized in
operating aload of incandescent lamps,
was transmitted during a rain storm at
voltage of $4,000 volts with entire
success. The efficiency was about as
| per cent
"A short time ago the Western Elec-
trician, of Chicago, published an ac-
count of the manner in which hose
cart was whislsed to fire in Chicago
suburb by being attached to an electric
car. Ont in Omaha, says the same pa

In which the tracks of the electric line
were laid, and in order to get it out of
the way as soon as possible the super
