creating new species.
Chicago scientists predicate from
the amazing results of their work, that
the surgeon of the future may so util-
lie the various organs of the body as
virtually to create, in some instances,
new men and in other instances in
definitely to prolong youth.
They believe they have discovered
how new species of animals have been
manufactured by nature, from the time
of the first monad, hundreds of mill
lions of years ago, down. to date. Fur
Their, they profess to regard life and
death as simple functions comparable
with other functions of an animal.
The genius of these Investigations
is DR.. Charles Manning Child, asso-
ciate professor of zoology. He has
given the results of some of his ex-
periments in a book entitled Scenes
cense and Rejuvenescense," just is
sued from the Chicago University
Press.
In an interview he describes some
of the astounding results of his work,
particularly in its bearing on the mys-
teries of life and death. In fact, he
doesn't consider such matters mys
teries at all. His statements follow:
1.-THE animals experimental with are
known as fresh water planarians of
several species. One species is found
in great abundance in various parts
of the country, chiefly in springs and
streams. They are less than one inch
in length.
SIN the laboratory, with abundant
food, their strength doubles. The body
is near fiat. The body wall consists
of a layer of skin, muscle layers be-
meath it, and with wall of tissue
protecting the internal organs.
'They have the nervous system,
with branches. Their chief organs of
sense are the eyes. These have pig
ment cups, containing sense cells, and
pointed lobes, which are organs of
chemical sense. Even the margins of
the head and body. are sensitive or
ga1s.
1.-THE mouth lies in the middle of the
body. 1t opens on one end into a
throat pouch, containing a tubular
pharnyx. On the other end, it opens
into the alimentary tract.
I'VE have also accomplished the
same result with various other fiat
worms, protocol, fresh water hydra
and several salt water hybrids.
If these simple animals are cut
into pieces, each pieces will become
a new small animal in the course of
a few days. In this change some of
the substance of the piece is used up
in making the piece over into new
whole animal
eff we cut an old animal into piec
es, we find that the new individuals
which develop from these pieces are
physiologically younger than the ami
NAL from which they were taken. The
making over of the piece into a whole
animal has in some way brought about
a rejuvenescense.
Sometimes these animals divide of
their own accord into two pieces and
each piece develops into a whole ami
NAL. In this case also the new animal
formed from the piece is younger than
that from which the piece comes.
I'm all of these cases of natural
and experimental production we find
that the smaller the part of the ami
NAL which is separated and develops
into a new animal, the younger the
animal produced. The smaller piece
must undergo more change than the
larger in order to become whole an
imal and uses up more of its sub
stance in the process and this evil
IDENTIFY makes it younger than the an
imal produced from the larger piece.
1.-The results indicate that senes-
cence or growing old, consists in a
gradual decrease in the chemical act
ivity in the body in consequence OF
changes in the body substance.
"As regards man, we may say that
the conditions and processes which
make him what he is are the same
conditions and processes which lead
to death of the individual in the end.
There is much evidence to indi-
cate that all reproductive processes
involve rejuvenescence.
Sooner or later, however, after the
developing individual begins to take
food from outside its own substance,
it once more begins to accumulate
the structural substances as parts of
its protoplasm and commences the de-
crease in chemical activity and with
it the process of growing old.
rs continued existence of a species
without growing old possible? Any
answer must be little more than mere
guess.
1T is possible that species may un-
dergo very gradual progressive
changes, not entirely eliminated or
compensating periods of individual re-
juvenescence. 1t is possible that the
union of two germ cells from different
lines of descent may be an important
factor in retarding or accelerating
such changes if they occur. In other
words, new species may result in such
union of two cells from different ami
mails, called mutation.
