UNIQUE THIRD DEGREE PLANNED

transmitted by wires to a small fiber
| which hangs suspended in the magnetic
field Of a powerful horseshoe magnet.
/ The disturbance of this fiber from its
normal position indicates the force of
the heart current. The fiber itself is
SO small that it is invisible to the naked
eye-.200 of them equaling the space of
an inch. Therefore, its action is watched
through a powerful telescope And, in
stead Of watching with the eye, the ac-
| ton Is received on a moving picture film,
which Is afterwaTd developed and repro
duced upon screen.
Just behind the fiber is a powerful
electric arc light which casts the shadow
Of the fiber through the telescope, thence
| through a powerful lense and upon the
| moving picture film, so that it is the
| shadow Of the current generated by the
| heart which is recorded upon the film
Another indication of the wonderful
delicacy OF the instrument is the fact
that in conducting an experiment with it.
the slight electric current generated by
the sweat glands in the palm of the
hands is neutralized and separated from
the current which comes from the heart
And this is the machine with which
Kopf will be given the third degree
He will not know that the experiment is
being performed. He will be seated in
an arm chair and questioned by Commits
sioner Ryder. But the chair will be con-
nected with the cardiograph in the next
room and every movement of his heart
viii be watched by the scientists and re-
corded by the machine. Afterward the
film will be developed and projected upon
a screen and every movement made by
kopfs heart during the ordeal can be
seen.
Old Can Center of Interest.
THE main portion Of the experiment
viii be cen.ered around an old tin can"
SAYS Police Commissioner Ryder. With
out saying anything to Kopf about il, one
Of my men will pick up an old tin can
which will be in sight. He will put his
hand down in the can and withdraw 1t
filled with money. At the same time there
will be a red stain on his hand as
though he had cut himself on the can.
In fact. 1t win be reproduction of the
robbery OF the old miser as told by
Shallenberger in his confession.
If Kopf Is Innocent all that will mean
nothing to him. On the other hand IL
he Is guilty he naturally will be excited
as his memory recalls the murder and rob-
berry. With excitement will come swift
er heart action. He may be able to
control his face, his actions. his express
sions. &c, but he never can control the
beatings Of his-heart. The little fiber In
the next room will be making an indel
ible record Of his real mental conditions
and when the moving pictures are thrown
upon the screen we will know whether
or not Kopf recognized the little pam
tomime which was acted in his presence"
Col. Ryder says the evidence adduced
by the electro-cardiograph Is not of a
nature which can be brought before a
jury. For the present its use is more for
experimental purposes than anything else,
but eventually he expects to see the ma
chine In general use for the detection
of criminals. In the present instance. Col.
Ryder viii have to secure the permis-
sion Of Sheriff Pones. OF Nemaha County,
where the crime was committed before he
can experiment on Kopf. He expects
no difficulty on this score. however and
is making the necessary arrangements to
carry out the experiment as planned. IL
successful. detailed statement and re-
port will be sent TO the police OF every
city in the eountry>---------.-,.s
