The Thomson Houston Electric Co.
Is said to control 1,O3O patents on its
electrical apparatus.
British oculists have been discuss
ing the question of whether the electric
light is injurious to the eyesight, and
they agree that it is not.
1t Is stated that in Aberdeen, Scot
land, tests are shortly to be made on
cattle killed by electricity, to ascertain
If the current has any detrimental eff
feet on the quality of the meat.
1t is now generally. held by electri-
clans that the principle of the aurora
oorealis is the same as that shown by
the Geissler tube, in which electricity
is discharged through rarified air.
The use of electricity in tanning
appears to be a success. One establish
ment in France has an annual capacity
of 600 tons of tanned hide, while in
Portugal there are two electric tanner
les at work.
Two new styles of arc lamps have
been put on the market recently, which
are intended specially for use in rooms
with low ceilings and in other places
where the light of the old style lamp
has proved inconvenient.
The Rochester IN. ~ electric cir
cults have been extended to run sewing
machines in houses on the outskirts of
the city, and there are, it is said, hum
dreds of people who are doing their
work for the large clothing firms in
these parts of the city.
The capital stock of the Bell Tele-
| phone Co. has been increased from $751;
600, 900 to S17, 7,500,O 900. The company has
in use 612, 4O7 instruments, and has 1870,
391 miles of wire on poles, 14,954 miles
on buildings and T0,334 miles under
ground, total of 5,679 miles.
The electric current on the 30th OF
March turned it's first furrow in Ameri-
can soil at the Kansas sorghum expert
mental station. The motor developed
ample power to plow deep and fast,
but it became evident that rheostat,
or resistance coil, such as is used in
starting electric cars is also necessary
with the electric plow
1T is an interesting fact that out of
16 cities of over 100000 population
in the United States, IA, or over
81 per cent, are using the electric rail-
way system, or equipping roads
with the system, and out of 42
cities with populations ranging from
100000 to $4,000, all but one are using
the electric system of street car trac-
tion.
The Electrical World notes the facts
that the municipality of Paris some
time ago offered prize for the best
electric meter; that the meter of Prof
Elihue Thomson, with that Of Aron
received the first prize, amounting to
100000, or about $4,000; and that Prof.
Thomson has just presented the money
won by his meter to the Academic des
Sciences of Paris. M
The Hummer electric fire engine
made by Messrs. Hummer, of Dresden
uses so amperes at 100 volts, or rs am
peres at IS volts, being 500 watts. The
pump throws 180 cubic feet of water
per second, and with nozzle of three
quarter inch diameter gives height
of throw of 100 feet. 1t weighs ~
tons, and costs only about half that OF
an ordinary steam fire engine.
| of great commercial interest, es
pecially to the United States, is the an
nouncement of the completion of new
ocean cable between the southern coast
of Florida and Nassau, New Providence
which will put the Bahamas in clost
connection with the rest of the civil
lied world. While this new cable il
only $50 miles in length, yet at NJ
distant day extensions will be made tx
all the islands in that region.
With regard to the influence O.
electricity on the growth of plants, &
series of experiments made by Prof
Aloi on lactuca scariola, maize, wheat
tobacco and beans, indicate that at
mospheric electricity exercises bene
fetal influence on vegetation; that tn,
electricity of the soil has similar in
fiuence on the termination of seeds
and that the less luxuriant vegetation
of plants which grow in the neighbor
hood of trees is in great part due to th,
diminution of temperature.
