THAT the cells of which the hui.
man body is composed can
live forever Is the remark
able conclusion reached BY DR..
Alexis Carrel, the eminent biologist.
as a result OF recent experiments
carried out at the Rockefeller In
stitute of Medical Resca rch.
II this be true. then, OF course
physical Immortality, the dream OF
ages, becomes possibility
Or. Carrel has been working along
these lines for several years. His
most recent experiments demou-
strate, in brief, that human cells
may be kept alive indefinitely if
sustained in the proper medium and
kept at the proper temperature. In
other words, Immortality, as far as
living cells goes, Is only n question
of protecting the cell from destruc-
tive forces and continually providing
II with the sustenance 1t requires.
Cells do not necessarily die. They
are killed by outside influences or
through lack OF nourishment
Curiously enough, Seneca, the
great Roman philosopher. declared
some two thousand years ago that
man doesn't die-he kills himself
Recent scientific research seems 10
indicate that this may be so, and
that If his various vital organs are
properly safeguarded, nourished and
renovated from time 10 time there
Is no reason why man should not
live forever. Physical Immortality
becomes now merely q matter OF
scientific vigilance.
DR.. Carols early experiments are
more or less familiar. A few years
ago his one great ambition was to
ascertain whether human tissue
could be kept alive outside of the hui
man system. Could q. microscopic
piece Of tissue be taken from the
body and kept alive in n glass YES
sel-in vitro, as the scientists desig-
nate 1t?
The scientist experimental along
these lines for years trying to find
proper medium in which to keep
alive the severed tissue His efforts
were rewarded with success. His
experiments demonstrated that hui
man tissue did not necessarily die
as soon as 1t was separated from the
body. BY immersing it in certain So
lutions, consisting principally of
blood plasma, he found that it con-
tlnued 10 i've
The next step was to ascertain
whether tissue thus severed from
the human body could be made to
grow. DR.. Carrel's experiments con-
clusively established that connective

And now further experiments have

the conclusion that this condition of
active life may be made to continue
forever
DR.. CarrePs most recent expert
ments were carried on during the
five months of 1913 with strains of
connective tissue cells derived from
tissues extirpated from embryonic
or adult chickens during the months
of January and June, 1912, and Feb
ruary, 1913.
The fragments Of tissue composed
of these cells were preserved in q
medium composed Of two parts Of
adult chicken plasma and one part
CT juice taken from q chick embryo
eight days old. Every two or three
days the tissue was removed from
ne culture medium, washed for thir-
II seconds or one minute in Ringer
solution, divided into two or three
parts If it's volume had increased,
and placed in a new medium at
temperature of thirty-nine degrees
centigrade.
This fragment soon surrounded
itself with large number of cells,
which formed a new tissue. After
forty-eight hours the ring Of new
tissue was measured with G micro
meter, an instrument for measuring
matter which can be seen only I'M
der microscope. It was found that
the rate Of growth of tissue thus
preserved remained constant as long
