The New York and New Jersey
Telephone Co, is said to be issuing

handsomely engraved passes which en-

They are experimenting with an
electric cab in Berlin by having it run
races with the ordinary horse cabs.
The reports to date seem to show the
superiority of the vehicle propelled by
electricity. A distance of six English
miles was covered by it in twenty min
utes, or at the rate of about three min
utes a mile.
With the introduction of the arc
lights in the south, it is said that nu-
merous bugs of more or less dangerous
species are attracted to the cities. One
OF these is termed the light electric. 1t

been considered harmless, but now it is
believed that they will bite or sting
with direful results. The Electrical
REVIEW tells of a case of poisoning oc-
curing by the bite of one of these crea-
lures, which produced great suffering.

into in England. Experiments have
been carried on for over year and a
half in one of the large Laboratories,
which have embraced testing ozone as
an exterminator of every conceivable
sort of insect, germ and bacteria, as
well as determining the exact cost OF
manufacturing it electrically on a
large scale. The results as given out

Ohio evidently appreciates the troll
ley better than any other state in the
union, for, according to the Electrical
Review, there are more lines of electric
railway representing greater amount
of capital invested in that state than in
any other portion of the country. These
roads, it appears, are used for freight
and passenger traffic, as United States
mail routes, and for carrying people
from cities and towns to summer and
pleasure resorts. Roads are now con-
templated and in course of construction

can be made SO that one may travel
from the eastern to the western bound.

ufacture of diamonds, by which some
perfect though minute stones have been
made, is thus described: About 200
grammes of mixture of cast iron and
carbonized sugar is placed in a crucible
OF carbon, resting in bed of magnesia,
the whole being placed in specially-de-
signed furnace, heated by an electric
arc to about 5000 deg. Centigrade. At
ter five or six minutes subjection to
this intense heat the crucible and it's con-
tents are plunged very quickly into
cold water. The interior is thus sub
jected to high pressure, which solidifies
the carbon. On dissolving the metal
with acid a number of very small dia-
monds are found. .
"A useful form of telephone has been
invented, whereby one instrument can
be used by persons in different parts of
building, so that communications NAV
be received in and sent from a room in
which no telephone is located. Speak
ing tubes are placed throughout
building, running from central office.
"a circuit wire is placed in connection
with each tube, and in a guest room, if
in hotel, or Office, is telephone re-
ceiver, which, when not in use. hangs
from peg. If this apparatus is used
in hotel, and a call comes to the Office
telephone for guest, the clerk calls
through the speaking tube to the
guests room that his attention is re-
quired. The guest.has only to take the
receiver from the peg in his room and
carry on conversation the same as If
he were directly at the telephone, prop
er connection having previously been
made in the office.
