purposes of a lantern.-An electrical
stop-watch has been tested in a
bicycle rake, where it determined
the winner although he was only
one-hundredth of a second ahead
Edison's electric percussion drill
can be worked at any distance up
to 3 miles from the dynamo, and
will bore 3 inches a minute into the
hardest granite.-The new electric
log is claimed to give much more
reliable measurements of the speed
of fast vessels than the ordinary ap-
paratus.
An ingenious camera for photo
graphing the internal organs OF men
or animals has been invented in
Germany. It is cylindrical in shape
is contained in a rubber tube, and
has two hemispherical shutters and
two minute incandescent lamps.
Pressing pneumatic ball moves the
camera forward in the tube, opens
the shutters, and makes the electric
light contact. Removing the pres
sure closes the shutters, puts out
the lights, and replaces the camera.
NEW ALLOYS.
This list of recetly invented alloys
is given by the GLASGOW Engineer.
Nickel-aluminium, composed of 20
parts nickel and parts aluminium,
used for decorative threads; zinc
nickel, composed of 80 parts zinc
and 10 parts nickel, used as pig
ment; nickel -hardlead, composed of
100 parts type-metal and parts
nickel, used for metallic types and
for electors; platinide, composed of
go parts platinum, 35 parts neckel, 2
parts gold and 8 parts iron, used
for crucibles and chemical utersels
rosein, composed of 40 parts nickel
10 parts silver 80 parts aluminium
and 20 parts tin, for jewelers. work
sunbronze, composed of 60 or 40
parts of cabalt, 10 parts aluminium,
40 or 3Oparts copper; metaline, com
posed of 35 parts cobalt, 25 parts
aluminium, 10 parts iron, and 30
parts copper.
LIGHTNING FROM A CLEAR SKY.
An English electrician, Mr.. A.
McAdie' has repeated Franklin's
kite experiment when no clouds were
visible. Sparks were drawn from an
insulated wire leading from the kite
to the ground, and an electrometer
was strongly affected. The quantity
of electricity so nearly correspondent
to the height of the kite that the
experimenter could usually deter
mine by the electrometer whether
the kite was rising or falling.
NEW FEvER-HoUsE.
Tropical countries have been ad-
vised to establish cold greenhouses
as hospitals. This idea has resulted
from the remarkable success of a
Cuban physician, who has been
treating yellow fever by keeping the
patients in artifcially cooled rooms.
It is proposed that each town in
districts liable to epidemics of this
disease shall build a great glass
house for the fever victims. These
houses would be artiicially cooled,
and plants of cold and temperate
regions would be grown in them.
SOUTH AMERICAN FIND.
The discovery of immense deposits
of rem lrkable mineral substance,
not unlike asbestos in its properties
has been reported from the United
States of Columbia. 1t has the
color of amber, is perfectly trans
parent, and cannot be burned. Elk
periments made at Bogota indicate
that it will be of great value for the
manufacture of bank-note paper, for
fire proof and waterproof roofing
tiles. and for incombustible suits
for fremen. A white varnish can
also be extracted from it. The SUBJ
stance has been named bucaraman-
quina, and it is expected to prove of
greater importance than asbestos.
Acurious misapplication of science
was recently witnessed in an attempt
to break up an operate performance
in Paris. Disorderly persons car
ried thin glass bulbs filed with
sulphide of ammonium, and these,
each loaded with the concentrated
fragrance of a hatful of rotten eggs,
were to be hurled at the performers
upon the stage.
The first iron suspension bridge
in ireland has just been opened. 1t
is 124 yards long, 3 yards wide and
has 6 steel wire ropes weighing 81,
tons each.
At Melbourne hospital yeast has
been used a remedy for typhoid
fever. In 81 cases-about half OF
them severe-there was no failure
to recover without relapse.
A new Ife-belt has been patented
