was necessary. as a chemical cast is
used, which is poured over the head in liquid
closely tight to every wrinkle, dent or up
heaval Of the skull that the slightest swell
ing or contraction may be noticed. On each
side of the cast there are two little disks.
There IS also one on top or the mead over
the spot which in babies is so soft-the spot
which remains soft in the heads or some IN
dividuals through life. These disks are in
turn connected with chemical disks by
means of wires The outside disks are in
turn connected with a battery. Expansion
or contraction in the head of the subject is
recorded on a graduate specially designed

trical processes and actions of which no one
except Mr.. Edison has any knowledge
After the chemical mask had been salts
factorily adjusted to the head of the boy
an opening having been made for the eyes
and little holes near the nostrils and ears
he was told to concentrate his mind on
horse race at the finish. Mr.. Edison de-
scribed in glowing terms the excitement as
the horses swept down the stretch neck
and neck, with the multitude yelling like
mad the jockeys strainng every muscle,
and all the other conditions which go TO
make hair-raising finish. the INDICATOR
the graduate went to point which, If
the marking of u thermometer had been
used, would have read boiling point. Then
MIR. Edison told his subject to turn his
thoughts towards death, a most solemn sub
ject. He pictured a coffin, with the dead
imagine that he was peering over the I'D
into the face beneath. This was almost
enough to make the boys hair stand on end
and his blood freeze in his veins. as was
indicated on the graduate, which showed a
dropping to about the 'zero-point.
Mr.. Edison was inclined to believe that
when the mind was occupied with thought
the eye reflected, in certain way. the sub
ject of the thought, and: therefore, he de-
vised a photographic outfit for the effort of
demonstration. This was machine with
long brass polished tube, containing on the
inside set of prisms, rejecting one to the
other There was also the necessary space
arranged in the tube for taking an X-ray
photograph. Of course, by this time the
subject had been released from his chemical
mask Now Mr.. Edison took a silver quar-
ter of a dollar, placed it on a piece OF white
paper and called the attention of his sub
ject to it, He had him look at 1T steadily,
uninterruptedly, persistenly, for the space
of minute and a half. Then he turned
him at once so his gaze was in straight
line with the polished brass tube and while
in this position Mr.. Edison turned on the
new Photographic machine, with its newly
discovered sensitive film, and took the
that, so sensitive was the film or chemical
substance used in the Photographic work,
would render it useless The film has great
attractive powers and collects dust par
ticles and other substances in the air with
the other end of the brass tube
AS a result of this test the film when de-
veloped (also by secret .process) showed
the outline of a. round object. Mr.. Edison
admits that this was only one experiment,
and that the round outline may be purely
accidental or imaginary. but he feels that
it is an indication of wonderful fields in
which electricity may find its usefulness.
One of the peculiar outcomes of the expert
ment was the fact that while looking in the
brass tube after having gazed for a min
ute and half at the silver quarter the boy
became self-hypnotzed. This in itself was
feature well worth looking after.
Mr.. Edison will continue experiments on
this invention at a laboratory which he has
In some secret, out-of-the-way place, and
he feels confident that he will make
cess of it. In connection with this device
for photographing thought he has made a
discovery which leads him to believe that
he can photograph colors. This will also
be taken up
