EXPERIMENTS HIT
E|NSTE|N THEORY
Cleveland Scientist Gre ate s
Sensation at Phiosophic
Society Meeting
DEALS WITH GRAVITATl0N

Perhaps Or. Einstein is au wrong
after all.
DR.. Charles F. Brush. Of Cleveland,
distinguished physicist described ex
pcriments in gravitatiOn to the Ameri-
can Philosophc Society today. which
members of the society declared proved,
il accurate. that the famous Einstcin
theory was incorrect.
Or. Brush's paper caused the great e
est sensation of any read thus far at
the sessions of the society, meeting at
1O4 South Fifth street His expert
ments were Of an extremely technical
nature, carried out with vnrious metals.
The scientists. assembled from all
parts of the country, applaudcd the
paper vigorously. There were many
expressions Of astonishmcnt at the re.
suits DR.. Brush had obtained
"lf these experiments are accurate,
commented DR.. 4. G. Webster. of Clark
University, Worcester. Mass. they
absolutely disprove the EinStcin the

Or, Brush said also that the theory
living behind his observations would
undoubtedly upset all our previous cal
culati0ns in regard to the density OF
the earth.
The paper was very fully discussed
by the scientists present.
This reveals startling fact about
gravitation." said DR.. Clark in dis
cussing Or. Brush : paper. 1--WE have
known the how Of gravitation since
Newton. but the why Of grnvitatior
is an absolutely new fact. Einstein' :
theory seems entirely disproycd by this
experiment, and | am 'tiabbCrgaSted.
For the last POO years we have al
ways believed without question. that the
inertia of body was prOpOrtionate to
its mass. Or. Brush says II is not.
Brush Theories Attacked
DR.. Clark went on to say that usinl
q pendulum for these experiments was
something new and probably accounted
for the results achieved.
Dr. Brush answered numerous Qucs
tions and showed StereOpticOn views O
the experiments he had made. Som,
Of the speakers attacked his theories
but answered all their questions un

Another scientist. discussing the pa

would be- better pleased than ProfssO
Einstein himself, for he said recently IL
conversation that he wished some on,
would either prove or disprove hi
theory so that further progress COulC
bc made.
DR.. Carl II. Eigenmann, professor o
Zoology at Indiana University. speaking
ON The Nature and Origin Of the FrpSl

Pacific Slope of Ecuador. remarked
that the fish in these regions were ode
