under exposure of an hour, not only eve
~ detail of the skeleton is visible, Dut
likewise a clear outline of the abdominal
cavity and the location of the lungs, the
FUR, and many Their features. Prints OF
even large birds show the feathers quite
distinctly.
Clear shadows of the bones of human
limbs are obtained by exposures ranging
from quarter of an hour to an hour,
and some plates have shown such an
amount OF detail that it Is almost i'm
possible to believe that we have to deal
with shadows only. For instance. pic
ture OF O foot with shoe on it was tax
en-, and every fold of the leather, trous-
ers, stocking, &C., is visible, while the
flesh and bones stand out sharply.
Through the body of the experim enter
the shadows Of small buttons and like
objeota are quickly obtained, while with
an exposure of from one to one and
the bones Of the upper arm appear clearly
as is shown in the annexed print. 1t is
now demonstrated beyond any doubt
that small metallic objects or bony or
chalky deposits can be infallibly detected
in any part of tho body
can outline of the skull is easily OBJ
tanned with an exposure of twenty to
forty minutes. In ole Instance an ex-
posture of forty minutes gave clearly not
only the outline, hut the cavity of the
eye, the chin, and cheek and nasal bones,
the lower jaw and connections to the up
per one, the ver tebral column and con-
nections to the skull, the flesh and even
the hair. By exposing the head to q
powerful radiation strange effects have
been noted. For instance, I find that
there is tendency to Sleep and the time
seems to pass away quickly. There is a
general soothing effect, and have felt q
sensation of warmth in the upper part of
the head. An assistant Independently
confirmed the tendency to sleep and o
quick lapss of time. Should the SO re-
keener sense of observation I hall still
more firmly believe in the existence of ma
terial streams penetrating the skull.
Thus it may be possible by these strange
appliances to project a suitable chemical
into any part of the body.
"Roentgen advanced modestly his re-
suits. warning against too much hope.
Fortunately his approximations were
groundless, for, although We have to all
appearance to deal with mere shad or
projections, the possibilities OF the appli-
cation of his discovery are vast. / am
happy to have contributed to the develop
ment Of the great art he has created"
Tesla has prepared five papers since
this one, in each of which he has told
about some branch OF the
new photography that had heretofore
neen unknown. Soms of the pictures
he has Obtained are wonderful The last
and the one that created the most talk Is
a picture Of man which shows, among
other things the outline of the heart.
Tesla showed this picture to the Sun
reporter, together with picture of leg
and foot, both of them remarkable speci-
mems of the work of the Roentgen pilot
ography.
Tesla was asked if he was well off, His
reply was:
If every man who uses my machine
in electro theurapy alone would give me
a quarter I would be very wealthy
mar. never received a dollar for it, and
there is no way in which / could. I re-
ceiye small income from my invention
in the rotating field, and have small
income from home. All this ! spend
here"
Regarding the future he has said:
~ expect to live to be able to set ma
chine in the middle Of this room and
move it by the energy of no other agency
than the medium in motion around us. >
