still discussing the remarkable discovery
announced to have been made by Prof.
Roentgen of the Wurzburg University in
Vienna. According to the stories which
come from across the water this wonder.
ful new method enables photographs to
be taken through substances which we're
hitherto considered impervious to light.
Human flesh, leather and wood seem
now to be no bar to the rays OF light and
pictures of the skeletons of living beings,
coins inside of closed purses, and pieces
of metal inside of wooden boxes are all
gwen as easy to obtain by the new pro.
cess. -
1t is evident the possibilities Of the new
discovery are endless, and Prof. Roent-
gen is credited with having taken some
remarkable negatives. One instance is
that of mans ankle wherein a bullet
was imbedded. The photograph shows
the bullet just as it is lodged in the ankle.
thus revealing what heretofore could only
be learned by probing and the use of the
surgeons knife. The coins in leather
purse were also photographed, showing
clearly through the supposed Opaque
covering.
A human hand was then subjected TO
the process. In the picture resulting
appears skeleton hand, the covering OF
| flesh seeming to have vanished as If by
magic. 1t must be remembered, too,
that this was not the hand of dead per-
son, but belonged to living, breathing
man, the remainder of the arm being SO
screened and arranged as to be excluded
from the focus of the tube-camera.
Perhaps the most most notable expert
ment related, which illustrated with
graphic clearness the eccentric power OF
the new discovery, was the photograph OF
a man seated beside young lady before
the photographer in ordinary dress, but
whom the negative shows perfect skele-
ton. To test the clearness with which
the new process would reproduce the
skeleton OF living subject negatives
were also taken by the ordinary method.
In the first case the spinal vertebre were
Reproduced in every detail, forming a
CHASTITY specimen of realism.
The secret OF the wonderful results said
to be obtained by the Roentgen discovery
is in the production of light rays of I'M
usual penetration and actinlc value.
These are obtained from what are known
as Geissler or Crooke tubes. The tubes
are made of small glass pipes from which
the air has been exhausted. When a
current of electricity from an induction
coil is sent through these tubes green.
ish blue pickering light is given out,
which possesses unusual ability to act on
Photographic plates and also to penetrate
opaque substances. In many ways these
light rays seem to be allied to the mag
netic waves produced bv Tesla in his re-
cent alternating current experiments,
where electric undulations are often sent
through brick walls without deteriora-
ton. Although wood, flesh, leather, and
number of similar substances are said
to permit the passage of the radiant
energy from Crooke tube, metal, bone,
and other substances are said to stop it
abruptly. Hence the power OF photo
graphing skeletons and metallic objects
inside of flesh, wood, or leather.
The Crooke tube used is arranged like
the lens of an ordinary camera, the in
duction coil-that is, the wire over which
the electricity passes into the tube--run-
ming from small storage battery arrang.
ed in the camera, and at the rear OF the
tube. Then over the end of the tube
from which the heat rays are focused a
heavy cloth is thrown 10 such manner
as to clearly outline the tubes cad, en-.
abling the operator to focus the rays
without difficulty. Thus it will be seen
that the photograph is taken through
this heavy cloth, as well as the substance
surrounding the object it is desired to re-
produce.
