guided by an Array picture. iHN
special equipment designed by Dr..
WullyamoZ includes the N-ray stand,
with a Horoscope, and surgical IN
struments differing from the ordl-
nary in being bent at right angle.
The patient is so placed that the
X-rays projected upward from the
bulb in the stand pass through the
wounded part and fall upon the tuor-
oscopic screen. First locating the
bullet accurately by observations
from different angles, the surgeon
guides his probe so that the shadow
at it's point touches the shadow of
the bullet, then cuts the skin. and.
adjusting his forceps by the shadows,
presses it vertically downward.
Opening the forceps and graspins
the foreign body, and kind of bullet
or shell fragment can be removed
in less than a minute.
Some interesting facts in the rapid
development of the aeroplane were
lately brought to the notice of the
London Royal institution. In 1912,
the Cody machine, winning the mill
tary prize, travelled at maximum OF
70 and a minimum of 4S miles an
hour, a speed range of 33 per cent;
and in 1914, Sopwith machine had
maximum and minimum speeds of
90 and 81 miles, a range of so per
cent. The power required for flying
at 70 miles an hour has been lessen
ed more than 10 per cent. by simply
changing the shape of the aeroplane
wires from round to oval.
The airs temperature range near
the earth's surface is given as about
131 degrees For from 1874 de-
grees accepted as the highest reading
for Ouargla, Algerian Sahara, to 97.6
degrees below zero at Verkhoyansk'
Siberia. Thermometers not proper
ly shaded from the suns direct rays
are thought to explain the higher
temperatures reported by travellers.
The very lowest record is 135 degrees
below zero, but this is the register
of a sounding balloon at height OF
10 miles above Java.
Haphazard invention has brought
to the United States results so mar
yelous that one can only vaguely
wonder what limits of achievement
will be reached in the dawning era
of scientific research by trained spec
ialists with apparatus of the highest
type. The research laboratory of the
General Electric company has al
ready put upon the market such
epoch-making products as drawn
tungsten wire, the nitrogen-flled
damp, and the Coolidge X-ray tube.
and has just made known the keno
tron" rectifier for high pressure cleo
trio currents. Based upon curious
effect noted by Edison, the kenotron
has been worked out chiefly by DR..
Irving. Langmuir. A metal plate IS
sealed into a vacuum bulb with car
bon or tungsten filament, and a cur
rent passes across the high vacuum
when the filament is charged mega
lively by an electric current and the
plate positively, but when the fila
ment is made positive no current
passes. The so-called "hernlonic
current" is attributed to the passage
of a stream of electrons, or negative
ly charged particles about 1900
times smaller than hydrogen atoms.
The kenotron changes alternating in
to direct currents very effectively,
but so far has been chiefly useful for
producing small direct currents at
very high voltages. as for X-ray work,
precipitating dust. etc.
A new gasoline-electric automobile
depends for its power on a two-cylln-
der water-cooled engine connected
directly to a five-kilowatt generator
operating at so volts. The storage
battery is in two sections, one-half
being placed on each side of the
chassis outside the frame; and the
motor is connected directly to the
rear axle through a double universal
jointed shaft and four to one reduc-
ing gear. The cars total weight is
about 5000 pounds. On ordinary
roads it can be run 20 miles by the
battery without aid from the engine,
and tests have shown an average
deficiency of 5S.5 ton-miles per gallon
4 of fuel.
The fire alarm siren heard II
miles from it's Colorado station is the
rotor of an electric motor. At $500
revolutions per minute air is driven
through II apertures in the rotor

90 vibrations per second, giving an
