ants. Ordinarily such differing indi
viduals are less well adapted than tn,
parents and soon perish. The law o.
nature Is that only the fittest individ

to be in this condition, especially tn,
more civilized races. It allows grea

The evolutionary theory Of descent
with notifications, Dr. Morgan said" Is
the only rational explanation of wide
range Of we'll aScertained facts. The
history Of evolution is of the same order
as that the Mayflower brought the Pill
grim Fathers to the New World. The
extant, written record Of their arrival 4
not very different from the record OF
the rocks as revealed by paleontolOgy
There Is no good reason to suppose that
evolution stopped when man appeared
There Is strong evidence that evolution
is going forward and backward today
as in the past"
One of the puzzles which Darwin and
the older evolutionists were unable tO
answer satisfactorily, DR.. Morgan said
was how a race with new features could
appear out Of an old one. But. he said
today geneticiSts working with fruit flies
are combining species on large scale
to produce hundreds Of new types, some
of which are self-perpetuating.
The mysterious cosmic rays which
lombard the earth from outer space
were declared by Prof Robert A. Milll-
kan and Dr. !. S. Bowen OF the Cal1for-
mia Institute Of Technology to comprise
by far the greater part OF the total
radiant energy in the universe. Less
than half the energy total comes from
the heat and light Of the stars, said
Prof. Millikan. In our own star sys-
tenn, in which the sun is only one OF
thousands and millions Of stars, he ex-
planned, the cosmic ray radiant energy
is nearly equal to all other forms.
New Heavy Water" Process.
Beyond our own star system, In the
spaces between 1t and the innumerable
other great galaxies, it was explained
the cosmic rays presumably are ]us'
as intense but by the time the ngh'
and heat of the stars reach those
regions of space they must be only
fraction of what they are inside oul
galaxy Hence the cosmic rays mus
make up most Of the energy.
Discovery of a new way OF making

Bureau of Standards He predicted
that the discovery may make necessar.
new chemistry and a new biology
The discovery makes possible for tn
first time the isolation Of quantities o
"isotopes" of oxygen and hydrogen
which are atoms with different weight
than the normal atoms of these ele
ments, but which otherwise are exactl.

by sending an electric current through
ordinary water, which takes out tn
lighter oxygen and hydrogen atoms
leaving behind only the heavy ones
The new water has many peculia
properties, including higher boiling ant
freezing points.
The isotopes have different chemica
properties from ordinary oxygen ant
hydrogen and can be expected to pro
