HUMAN BODY LUMINOUS
How Photographs Are Made by
Light Emanating From It.
SCIENTISTS AMAZED AT DISCOVERY


Professor A. W. Goodspeed shows
That Rays From His own Body Act
cd ON Film In one-aixth Of the
Time by the Roentgen Lieht--How
Experiments We're Conducted.
The scientific world stands amazed at
the discovery made by Professor Ar
thur w. Goodspeed Of the Randall Nor
gan Laboratory Of Physics Of the Uni
verslty of Pennsylvania that photo
graphs can be made by light emanating
from the human body, says a Philadel-
phia dispatch to the New York Ameri-
can.
Professor Goodspeed, who has long
been recognized for his important re-
searches Ia the realms Of the light ray
and who il president OF the American
\ Ray society, has proved the exist
ence OF a hitherto unknown ray thrown
out hy human beings, by means Of
which pictures can be taken in five
minutes, which is one-sixth Of the time
required for the production Of a radio
graph BIZ means Of the X ray.
The indisputable proof Of Professor
Goodspeed's remarkable discovery ex-
lists in a photograph of a human hand
taken BY means Of the emanations Of
light from the other hand.
Here is Professor Goodspeed's exnla
nation Of the amazing phenomena res
yealed by his discovery:
"All matter ahsorbs radio active en-
ergy in waves of varying lengths and
gives off this same energy in waves of
a changed and definite length. The en-
6rgy that has been thus transferred Is
characteristic Of the matter that II
gives forth. The human body gives
out the rays or waves Of this energy
with comparative freedom and force.
1T is 70 be presumed that Che char
aeter Of the human rays varies 10 an
infnitesimal degree with the person
End tiiat each man, woman and child
gives forth not merely the characteris
tic human light, but light that is alb
solutely unique and identifying,
''These rays from the human body
are not sufficient to be appreciated by
the human eye. 1t may be that they
are seen by The eyes d smaller ami
mails. For instance, d mouse probably
sees Il man in a dark room by the light
Of the man himself
Professor Goodspeed conducted his
experiments with the aid of d Crooke's
tube, but the Y rays lowing from the
tube were not permitted to proceed to-
ward the Photographic plates. The OBJ
ject Of using the Crooke's tube was to
have Professor Goodspeed's body alb
sorb the X ray waves and transform
them into different kind Of ray. and
from the latter the photographs We're
made.
Professor Goodspeed says, however,
that this process Of absorption, trans
formation and diffusion Of rays from
the human body goes on without the
presence Of a Crooke's tube.
The photographs he showed, he says,
were made BY putting Crooke's tube
In operation inside of d light proof
black box. This box was placed 80
that the platinum plate directed the
rays upward and on top Of the box be
piled up five pieces Of lead. which is
impervious to the X rays
on top OF the box was also placed a
cylinder Of brass with d small aperture
In it, side Within the cylinder and
resting on the It'd Of the box he placed
cent a gold ring and piece Of alu
minimum. The top Of the cylinder was
sealed with two heavy pieces of zinc,
Tho only way that rays could reacl
the objects to he photographed was
through the opening ia the side of thg
cylinder All the tune the room was ii
absolute darkness.
Professor Goodspeed held his hanC
three inches from the opening of TIA,
cylinder for three minutes. Then ths
plate was taken from its box and de
veloned, and Oh it were found the radi
ographs Of tie ring, the cent and th'
piece Of aluminium
This picture. Professor Goodspeet
declares, was produced by the second
aiy activity emanating from his hanG
under the influence Of the X rays.
Professor Goodspeed does not pro
fess 70 be the first 10 demonstrate TIL
principles upon which the discovery 1
based. He acknowledges himself in
debted to certain developments h'
