new VIEW OF
EARTH ORIGIN
ISSET FORTH
Old "Nebula Hypothesis" Attack
ed By Prof. Chamberlain Of
Chicago University

Chicago, Nov. 17.-New doctrines
of geology, based on a new theory of
the origin of the earth. were outlined
to the National Academy of Sciences
here today by Prof. Thomas C. Cham
berlin, emeritus head of the depart
ment of geology of the University OF
Chicago.
Emphasizing the revolutional mo-
tions of the earth as planet, which
have largely gone unnoticed in geol
Ogy. Prof Chamberlin declared that
they were some thousands of times
greater than the more tangible vi
bratory energies" such as light, heat
and sound
Describing the old view of the neb-
ular hypothesis that the interior of
the earth is molten, Prof. Chamberlin
told the Academy that it was solid.
Prof Chamberlin, who is one of the
worlds foremost biologists, present
ed two papers: The Contrasted
Types of Earth-Energy and Their Re-
lation Values" and THE Paths TAX
en- by Energy in the Self-Compres-
sion of the Earth" Prof. Chamberlin
called attention to the fact that the
older studies of the earth related
chiefly to its substance and that re-
Gently attention has turned more
largely to its energies.
He pointed out that formerly it was
supposed that the earth was once in
a gaseous state and that it condensed
from this into a molten globe. Its sur
face confguration and it's deforma-
tions were assigned to cooling. The
studies of the earth's energy and mo-
mentum. however, relieved serious
difficulties in making such a history
fit the facts disclosed by later inves-
tigation. DR.. Chamberlin abandoned
the old view some twenty years ago
and offered a new view known as the
planestesimal hypothesis. Under this
view the earth was built up very
slowly by gathering in minute bodies
whose energies and momenta were
of the same sort as that of the plan
cts into which they are gathered and
hence they met the old difficulties.
The new view, however, makes it
necessary to recast many of the old
doctrines of geology to bring them in
to accord with the new basis. Dr.
Chamberlin has been at work upon
this for several years.
His first paper today brought out
the remarkable preponderance of
the constructive revolutional ener-
gies over the agitative vibratory en-
ergies."
This appears to have escaped at
tention," Prof. Chamberlin said, "be-
cause the former are so singularly
unobtrusive. The latter, though much
inferior in real value, are very DEM
onstrative and have had the lions
share of attention.
1.-The revOlutional motions of the
earth as planet and the similar mo-
tions now believed to be essential fea-
lures of the atoms, largely escape or
binary notice, while the vibratory ac-
tons, such as sound heat, light, the
X-rays, etc, make themselves felt
very keenly, especially if these are at
all intense
I'VE are so constituted that we are
sensitive to these agitative energies,
but not to the other type Our sense
Impressions need therefore to be rec
titled"
By estimates of the real values of
the two types. DR.. Chamberlin showed
that the unobtrusive revolutional en-
ergies connected with the earth are
some thousands of times greater than
the more tangible vibratory energies.
The two kinds, however, cooperate
with one another and are mutually
interchangeable.
DR.. Chamberlin's second paper re-
lated to the self-compression of the
earth. Under the new view, this is
merely the pulling together of solid
body by its own attraction. The earth
grows more and more solid as the
work goes on, he said. Much of the
energy goes to make up more COM
pact and more resistant structures.
Some, however, goes to liquify the
more Equitable substances, but these
are squeezed out about as fast as
they reach squeezable volumes. They
thus leave the interior solid
