spscsaI Despatch to TEE NEW York HrsArD
CHICAGO, Dec 80.-The latest inven-
tion described at the meeting Of the
chemists branch Of the American As
Science was offered to-day by w. r.
Miles Of the Carnegie Nutritional In
stitute Of Boston. It is modern and
timely and it comes in the form Of
machine--the "hootch detector."
With the aid Of this machine 1t is
said to be possible to gauge almost to
q drink the amount of liquor a man
has consumed. With it's aid an alco-
holic enthusiast can determine to a
fractional per cent. If the bartender
told the truth about the strength OF
the drink he served.
The machine is simple enough in
operation. according to the descrip-
ton. There are two knobs which the
subject grasps. Electric currents
swing into the knobs and the subject
is disturbed"
Just how much he Is disturbed is indi-
Gated on a gauge which Is normal at
zero that Is the point on which the sub
ject must keep the gauge needle If he is
to convince the observer of his sobriety.
The machine, according to Its inventor,
also will record the reactions of a subject
reading Shakespeare and the activity Of
other emo tions produced by other causes.
The inventors description of the appara-
tus follows:
Description by Inventor.
This is new apparatus for measur-
ing the adequacy of eye and hand coordi-
nation which probably Is one of the
most important forms of human behav-
ior to measure in connection with nu-
tritional factors, fatigue. Industrial rela-
tion and so forth
"The subject under test observes a
wattmeter with zero centre scale and by
the manipulation Of a rheostat tries con-
tlnually to maintain a balance between
two opposing electrical currents.
THE task is fairly uniform in nature,
but so varied as to the direction, ampli-
tude, rapidity of fluctuation and rate of
change in the current strength of one of
the circuits as to require constant atten-
ton from the reactor.
THE disturber mechanism can be reg
ulated to provide tasks of varying diff
culties. The errors of compensation are
integrated in two meters from which the
score combines with quickness and accu-
racy, and the smaller the meter reading
Is the better the performance is"
Proof that the world is lying in a huge
magnetic field of an origin unknown but
foreign to itself, with a faculty for maxi
ing more trouble for the mariners COM
passes in certain circumstances than
Senator Johnson did with the peace
treaty. was submitted by Prof. Louis A.
Bauer.
The experiments which enabled Prof.
Bauer to make this announcement COW
cred a long period. and included obser-
vations of the magnetic effects of four
rolar eclipses, coupled with data gath
cred from the different observatories Of
the world
The currents from this field, he assert
ed, entered the revolving earth in the
regions of the two poles as negative
waves and emanated at the equator as
positive, much after the fashion of the
armature of toy magnetic
Professor Bauer didn't attempt to ex-
plain the source Of this mysterious enor-
gy--he merely contented himself with
announcing the proof OF its existence
But IL may, he thought. be one OF tine
number of retardent forces upon the
earths speed in revolution. and to be re-
Sensible for some of the heat which
exists beneath the first mile or so of
the crust of this planet on which we
live.
II am absolutely convinced" he told
his audience, "of the existence of lateral
electrical currents which pass directly
down into the earth. in addition to those
horizontal currents which have been rec
ognized for years.
Without them. we cannot account for
all the earth's magnetism. When all the

with we have from to 3 per cent. CT
the earths magnetism which is caused
BY these downward positive currents"
Compnsses Varied.
During a recent total eclipse Prof.
Bauer made extensive magnetic observa-
tions. AS the light of the earth was cut
off by the shadow Of the sun the COM
passes which he and his associates wero
watching at the different observatories
varied in direction.
'.Light is a conductor of electricity"
he continued. Shutting off the suns
rays shut Off these lateral electric cur
rents and disarranged the earths mag
netic field."
His observations, he also said, indi-
Gated a certain magnetic attraction be-
tween the earth, Venus and one or two
of the other planets.
With the psychologists. Billy Sunday
and his fellow revvalists were put un-
der the analytical microscope, so to
speak. by Prof. w. T. Shepherd of
Washington. DIR. Shepherd watched the
revival methods of ten ministers and
fifteen professional evangellsts. Many Of
them. he said. made their appeals with
out knowing why. and few didn't even
study the subject about which they were
preaching.
Most of their conversions were made
from members OF the audiences In the
late teens. The appeals were as a rule
based on fear OF death and hell, a hope
Of reward and appeals to the conscience.
Every one OF the twenty-five. he said,
believed in advertising. and advertised
his meetings in some form or another.
