30-MiIIion-Yeur History
In Seu-Bottom Cores
Samples Collected in Pueifie
Studied by Scientists
By Thomos R. Henry

Fifty-foot-long cores from the sea
bottoms are providing record Of more
than 80 million years Of earth's history.
These cores were collected four years
ago, largely in the Pacific, by the Swed-
ish Deep Sea Expedition, but extensive
analysis was required before any con-
clusions could be drawn. The ocean
floor is built up through the centuries
In large measure from dust which falls
from the sea surface rather than from
erosion from the land
These cores were the subject of an
exhibit before the British Royal Society
a few weeks ago. Some fantastic anom-
allies have been uncovered. For example,
the content Of nickel is from three to
four times that of the average for the
land surface. Thus it could not pos
Sibly have come from land deposits.
Cosmic Dust Theory.
The only logical explanation. accord
ing to DR.. E. J. Opik Of the University
Of Dublin, who has studied the samples.
is that the deep ocean floor deposits
are made up largely Of cosmic dust
which comes from the outer edge Of the
solar system.
1t has long been observed that me-
teorites contain considerably more nickel,
on the average, than the crust of the
earth. The dust must be considered
as consisting of essentially the same
material as the shooting stars.
DR.. Opik calculates that the amount
OF this invisible dust is so great that
about three feet of ocean floor will be
built UP in about two million years. For
the past million years. the cores indi-
cate fhnFa
amount Of cosmic dust hitting the sea
surface. This may be accounted for by
the assumption that the solar system is
passing through vast cosmic dust
cloud. Very little of this dust, actually
only the smallest particles moving at
the greatest speeds, reaches the earth.
Most is drawn in and captured by the
gravity OF the outer planets.

How about krebiozen?
few months ago DR.. A. C. Ivy, vice
president of the University OF Illinois
and one Of this countrys foremost
medical scientists. announced that he
had produced dramatic remissions Of
disease in small series Of patients with
advanced cancer.
The substance used was krebiozen,
developed in Buenos Aires and brought
to the United States by DR.. Steven
Durovic, Yugoslav biologist who spent
much OF the last war in a German con-
centratiOn camp. The announcement
naturally has brought a'fiood Of in
quiries from all over the United States
to all cancer agencies, particularly the
National Cancer Institute of the Public
Health Service.
Answers Discouraging.
1t has been necessary to return some
what discouraging answers. The ma.
terial is under clinical investigation. /"
Under the biological control law it can
not be sold. 1t can be supplied to re-
sponsihle investigators only through DR..
Ivy.
Meanwhile. according to the National
Cancer Society," early and incomplete
data from several clinics do not seem
nearly so rosy as the original announce.
ment."
Still, 1t is explained, the theory behind
kreblozen is fascinating and it may have
opened new line of approach to one
OF the major problems which confronts
science.
The substance is extracted from the
blood serum Of horses after stimulation
OF one type of blood cell. The hypo-
thetlcal basis of the preparation rests
on the assumption that every living cell
contains regulator which keeps its
proliferation-dividing in two to pro-
duce new cells-in line with the needs
OF the individual.
krebiozen, DR.. Durovic says, is this
regulator. 1t is assumed to be particu-
larly abundant in the type of blood cells
which are stimulated.
Cancer, he holds, is due to the fact
that cell growth is not properly regu-
lated because the individual has too
little krebiozen.
The treatment, he holds, will normal
ize cells in the early stages of malignancy
and those in advanced stages will be
killed or damaged.
Results to date are difficult to inter.

position of the material or the exact
method of its preparation.
