Force, Not Weight or Convolutions,
Gives Brain Power, Says Dr.. MelIus.
Three doctors from Johns Hopkins
university Of Baltimore. by actual dem
onstration on living animal, showed
members Of the Federation of Ameri-
can Societies For Experimental Biolo-
gy, in session in Philadelphia, that it
was possible to remove every drop of
blood from living animal. clean the
blood Of its impurities and return it
to the animal without interrupting the
heart beats.
The demonstration was made on a
dog. The demonstrators were Profess
sor j. ]. Abel and two Of bis colleagues,
DR.. L. G. Rountree and DR.. B. B. Tur-
ner, all of Johns Hopkins. In their
experiment they had every drop Of
blood out Of the dogs body and cours-
ing through coil of tubes whose con-
nected length measured nearly fifty
feet.
Onlookers Amazed.
Scientists who watched the demon
stratiOn in wonder saw the entire cir
culation Of an animal going on in glass
tubes outside the animals body and
blood propelled through the tubes by
the action of the dogs heart, which
never stopped beating while they
watched it,
At the same time, by the use of a
salt solution. through which the blood
was coursing. the animals blood was
being purified of sugar. urea and all
diffusable materials. By varying the
solution and sending the blood through
chemicals of different sorts, other kinds
of poisons can be removed from the
blood by the same process.
Professor Abel and his colleagues
would venture no prediction as to a
practical application OF their method.
Scientists who witnessed the demon
stration, however, did not conceal their
enthusiasm over the channel of op-
portunity opened up by the Baltimore
men.
IF this method of diffusion removes
urea from the BLOOD" said one, 1T
can be used as cure for uraemia. By
varying the chemical the same process
can be used to remove acetone from
the blood. the poison associated with
nephritis.'' ~
May Remove Bichloride. ..s.<5s
DR.. w. Salant. head of the federal
public health service at Washington.
made this comment:
"This apparatus is positively the
newest thing for cleansing the blood.
1t is the most interesting thing in
this convention. 1t may be possible.
though I have not tested this machine,
to remove bichloride of mercury from
the Blood
DR.. A. J. Carlson of the University
of Chicago demonstrated on himself
the efficiency of hunger testing ma
chine, which is his own. invention.
DR.. Carlson defined hunger as SEN
sation which arises in the stomach.
while appetite, he explained, is a nerv-
GUS phenomenon of the brain. He sWal-
lowed small cigar shaped rubber bal
loon which had been fitted with long
rubber tubes. inflated the balloon in
his stomach through the tubes and
then attached the latter to sensitized
paper.
Hunger, he said, caused the muscles
of the stomach to grip the balloon and
drive out the air which registered the
amount Of hunger on the sensitized
paper.
Upsets Old Brain Theories.
In recent paper read before the
American Physiological society Of the
University Of Pennsylvania by DR.. e.
Linden Mellus of Johns Hopkins uni
versity he contradicted the theory &C.
cepted by many scientists that the in
tellectual prowess Of human beings de-
ponds to large extent on the con-
volutions and size of the brain. His
announcement was assumed to have
opened up an entirely new field for
scientific research.
1.-The theory that the weight of
brain has anything to do with it's eff.
ficiency,' DR.. Mellus said. "was of
course exploded long ago. The later
theory, generally accepted, that intri-
cate convolutions were sign of brain
power or efficiency seems based rath-
er on the desire for anatomic explana-
ton than on any procurable facts. l
have investigated countless brains of
all classes Of individuals, and I have
yet to meet with anything that would
bear out this theory"
The results Of investigations. said the
physician, convinced him that some
mysterious force not yet found or de-
fined and as strange as the nerve i'm
pulse itself animated the brain cells.
changed their formation and their re-
lations and thus made for or against
mental efficiency regardless of the size,
weight or outward appearance Of the
brain itself. <@
