THOMAS A. EDISON.

at once rcvOiutlOnlZes anu intellectually
widens the horizon of the medical world
The great inventor has fulfilled the prom.
ise made to the world one week ago-he
has laid bare To the eye of the physician
and the surgeon every organ and tissue
and bone OF the human body. The sim
plest mind can grasp what this means
In the diagnosis, tho treatment, and the
actual observation Of the progress of In
ternal diseases
Everything Is Plainly Seen.
II Is very simple TO Mr. r lison. With
the powerful cathode light behind his
patient he gaZss through q screen of pro-
pared chemicles and sees every organ OF
the body "a plainly as he sees the dishes
on his dinner ra5io II his subject stands
close to the light nothing whatever Is seen
the light goes through bones and every
thing just as sunlight goes through glass.
Ii the patient steps foot or two away
from the light The human skeleton stands
revealed. A step further from the light
and the muscles, tissues and organs of the
body appear as plainly rs If there was no
outside covering of flesh. And so on as
the distance from the light and the focus
Is changed Mr. Il lisou Is now complet-
ing huOrescent screen eight feet high
which will enable him To see all this
from the top of the head To the soles Of
the feet.
Former Promise Is Fuifiiied.
Last week Mr. Edison was experiment.
ing to find n fiuorcscent screen. When
find that, in its most perfect form, shall
sec anything want to see as soon as tho
light tubes are perfect" he then said.
The screen has been found and Mr. Edi-
son has made good his promise Tho
fluorescent substance used by Mr. Edison
and declared by him to be the most per.
foct thing of the kind discovered so far Is
tungstate of calcium. In other words,
tungstate and lime The two substances
are fused in a furnace, and ut a proper de-
gree OF heat form little crystals perhaps
one-eighth the size of French pea
These crystals are glued to piece OF pa
per by means of colodium. transparent
celluloid paint. In the case of the huge
screen that Mr.. Ellison Is building for
taking in at glance the entire internal
organization Of a man, the crystals would
be spread directly OH an inch plank.
Like Mil Hopper.
The screen is made in the shape Of
monster mill hopper, standing on end.
Inc lace Oh WHICH tne Crystals are hp-
piled will be about : feet high and feet
broad. To this face will be fastened
sides that will slant inward to sharp
point. AT this point there will bs left u
slit just large enough to see through with
ease This slit will be protected by means
Of rubber flap In such way as To ex-
clude all light when the eye Is applied to
it. The screen will be set up so that the
side on which the tungstate OF calcium
has been glued faces row Of four or i've
Crookes tubes set, one above the other, at
an equal distance. The person to be ex
anined will then step in between the
screen and the light and he will be In
stantly penetrated and become visible TO
the eyes OF the examiner at the screen.
Not Necessary to Disrobe.
Every defect of every organ will be laid
bare to the physician OF other person who
Is making the examination. 1t will not
be necessary to go to the trouble OF disrob-
ing, as the clothing worn will be penc-
trated as II IL were the fiimsiest mosquito
netting AT three feet from the row Of
Crookes tubes the rays are SO powerful
that they will penetrate everything and
show nothing OH the screen except vague
shadow. Then at four feet matters be-
come more distinct; the rays are not SO
powerful aud show nm outline Of the bone.
AT five feet tho bones are seed distinctly;
they are no longer penetrated. AT six
feet the bones and the internal organs Of
the body are clearly seen.
