Courier Democrat. (Langdon, N.D.) 1891-1920, 1910-08-04

LII. DupfaC was waiting Tor them IN
his laboratory, absorbed in recording
the results of his latest experiments.
A kind eyed, grave faced man was
this, who, for all his modesty, was
famous over Europe as q brilliant
worker in psychological criminology.
Entering the laboratory, they found
themselves in a large room, quite dark,
save for an electric lantern at one
end that threw a brilliant circle on a
sheet stretched at the other end. The
light reflected from this sheet showed
the dim outlines Of a TERED amphithe-
alter before which was a long table
spread with strange looking instru-
ments.
Everything is ready" said DR.. Du-
pratt. "Is this the-er-the subject?"
He glanced at the prisoner.
Hauteville nodded.
"Please bring him over here. That's
right-in front of the lantern.' Then
he spoke gently to Groener, "Now, my
friend, we are not going to do any
thing that will cause you the slightest
pain or Inconvenience"
For some moments he studied the
prisoner in silence.
Interesting, very interesting" MUIR
INJURED the doctor. ESPECIALLY the
lobe of this ear. 1 will leave a note
about it for Bertillon himself. Please
turn a little for the back of the head.
Thanks! l must study this head when

must have these off," he pointed to
the handouts. "Also the coat. Don't
be alarmed. There! Now, I want the
left arm bare above the elbow" When
these directions had been carried out
DR.. Duprat pointed to a heavy wooden
chair.
please sit here" he went on, "and
slip your left arm into this leather
sleeve"
"Why must I sit in this chair" ask
ed Groener. why do you want my
arm in that leather thing?"
"Some pictures of persons and places
will be thrown on that sheet, and as
each n appears I want you to say
what it is. Most Of the pictures are
familiar to every one"
"But the leather ~sleeve?"
"The leather sleeve is like the stop
watch; it records your emotions. Sit
down"
Groener hesitated. II want to know
how it records my emotions"
The magistrate answered. "There
Is a pneumatic arrangement" he ex-
planned, "by which the pulsations Of
your heart and the blood pressure in
your arteries r registered automat-
ically. Now, then! I warn you if you
don't sit down willingly-well, you had
better sit down." Then Groener sat
down.
Quickly the assistant adjusted the
leather sleeve over the barred arm.
Immediately a familiar scene ap-
peared upon the sheet, a colored pho
tograph of the Place de la Concorde.
"What is it?' asked the doctor pleas
antly.
The prisoner was silent.
"You surely recognize this picture.
Look! The obelisk and the fountain,
the Iu1lerleS gardens"
"The Place de la Concorde," an
swered Groener sullenly.
The picture changed to a view Of the
Grand Opera House. and at the same
moment a point of light appeared in
the headpiece back Of the chair. It
was shaded SO that the prisoner could
not see it. and 1t Illuminated a grad
uated white dial on which was a glass
tube about thirty inches long, the
whole resembling a barometer. Inside
the tube a red column moved regularly
up and down, up and down, in steady
beats. and Coquenil understood that
this column was registering the beating
OF Groener's heart. Standing behind
the chair, the doctor. the magistrate
and the detective could at the same
time watch the pulsating column and
the pictures on the sheet, but the pris-
oner could not see the column.
what is that?" asked the doctor.
Groener answered at once, "The
Grand Opera House,"
Good! Now. another"
'"The Bastille column"
"And this?'
'Notre Dame church."
So far the beats had come uniform
ly about one in q second, for the mans
pulse was slow. At each beat the
liquid in the tube shot up six inches
and then dropped six inches, but at
the view of Notre Dame the column
rose only three inches, then dropped
back and shot up seven inches.
The doctor nodded gravely, while
Coquenil, with GREATNESS interest.
with a morbid fascination, watched
the beating Of this red column. 1t was
like the beating Of red blood.
"And this?"
As the picture changed there was a

itation with a quick fluttering at the
