TESLA ON THE X RAYS
THEIR ALMOST MAGIC POWERS
SHOWN BY HIM.

The Yong electrician Obtains Results
That Suggest New Fields of Usefulness
For Professor Roentgen's Discovery--MAy
Cure Diseases with Rays.
An article by Nicola Tesla is pub
lished in the current number of The
Electrical Review describing his expert
nients i'll photography. The scientific
world has been eagerly awaiting an ex.
preston Of opinion from Mr.. Tesla.
who is known to have begun his expert
ments within half an hour after the
news of Professor Roentgen's discovery
was cabled to this country. Two re-
markable photographs are printed with
the article. One of these shows the right
shoulder of "a man taken through his
clothing and through plate of glass
three-sixteenths of an inch thick and
two inches of wood This photograph,
which was made at the distance of four
feet from the source of the X rays,
shows the ribs, shoulder bones and
bones of the upper arm. The other radi
ograph shows copper wire bent to
form the word "Roentgen, and was
made at a distance of / feet from the
wooden slide covering the sensitized
plate.
Mr. Tesla also states that the rarefac-
ton of Crookes tubes used in these ex-
periments may be increased by electrical
means to any degree desirable, far be-
yond that obtainable by mechanical APP
planes. In regard to the nature of x
rays he says:
am getting more and more con-
WINGED that we have to deal with a
stream of material particles, which
strike the sensitive plate with great We
locities. Taking as a basis the estimate
of Lord Kelvin on the speed of project
ed PARTICLES in Crookes bulb, we ar
rive easily by the employment of very
high potentials to speeds of as much as
hundred kilometers second. Now,
again, the old question arises, Are the
particles from the electrode or from the
charged surface generally, including the
case of an external electrode. projected
through the glass or aluminium walls,
or do they merely hit the inner surface
and cause particles from the outside of
the wall to fly off, acting in purely
AiSShdhttdi ways as NHtn IOM vi lSOIy
balls is struck? So far most of the phe-
nomena indicate that they are projected
through the wall of the bulb, of what
ever material it may be, and | am seek
ing for still more conclusive evidence
in this direction. 1t is now demonstrate
ed beyond any doubt that small metal
lie objects or bony or chalky deposits
can be infallibly detected in any part Of
the body"
Tesla has also secured photographs
showing the bony structure of birds and
rabbits, even to the hollow of the bones.
He has secured photograph of rabbit
after an hours exposure in which not
only every detail of the skeleton is visi-
BILE, but also clear outline of the alb
domiual cavity, the lungs and the fur.
photographs of large birds show the
feathers distinctly. in another instance
an exposure of 40 minutes gave radio
graph of the human skull, showing
clearly not only the outline but the
cavities of the eye, chin, cheek, nasal
bones, the lower jaw and connections to
the skull, the flesh and even the hair.
Mr.. Tesla concludes his communication
as follows:
By exposing the head to powerful
radiation strange effects have been noted
For instance, find that there is tend
ency to sleep, and the time seems to
pass away quickly There is a general
soothing effect, and have felt a sensa.
tion of warmth in the upper part of the
head. An assistant independently con-
firmed the tendency to sleep and the
quick lapse of time. Should these re-
markable effects be verified by men with
keener senses of observation, shall still
more firmly believe in the existence of
material streams penetrating the skull
Thus it may be possible by these strange
appliances to project suitable chemical
into any part of the body.
'Roentgen advanced modestly his re-
suits, warning against too much hope
Fortunately his apprehensions were
groundless. for, although we have to all
appearance to deal with mere shadow
projections, the possibilities of the APP
plication of this discovery are vast. -
