energy of formation.

The mistiness again appeared in the air, and became a globe, a globe of
brown. But it changed, and disappeared. Morey recognized the signal. "He
will now make the artificial matter into all the elements, and many
nonexistent elements, unstable, atomic figures." There followed a long
series of changes.

The material shifted again, and again. Finally the last of the natural
elements was left behind, all 104 elements known to man were shown, and
many others.

"We will skip now. This is element of atomic weight 7000."

It was a lump of soft, oozy blackness. One could tell from the way that
Arcot's mind handled it that it was soft. It seemed cold, terribly cold.
Morey explained:

"It is very soft, for its atom is so large that it is soft in the
molecular state. It is tremendously photoe-lectric, losing electrons
very readily, and since its atom has so enormous a volume, its electrons
are very far from the nucleus in the outer rings, and they absorb rays
of very great length; even radio and some shorter audio waves seem to
affect it. That accounts for its blackness, and the softness as Arcot
has truly depicted it. Also, since it absorbs heat waves and changes
them to electrical charges, it tends to become cold, as the frost Arcot
has shown indicates. Remember, that that is infinitely hard as you see
it, for it is artificial matter, but Arcot has seen natural matter
forced into this exceedingly explosive atomic figuration.

"It is so heavily charged in the nucleus that its X-ray spectrum is well
toward the gamma! The inner electrons can scarcely vibrate."

Again the substance changed--and was gone.

"Too far--atom of weight 20,000 becomes invisible and nonexistent as
space closes in about it--perhaps the origin of our space. Atoms of this
weight, if breaking up, would form two or more atoms that would exist in
our space, then these would be unstable, and break down further into
normal atoms. We don't know.

"And one more substance," continued Morey as he opened the relay once
more. Arcot sat down and rested his head in his hands. He was not
accustomed to this strain, and though his mind was one of the most
powerful on Earth, it was very hard for him.

"We have a substance of commercial and practical use now. Cosmium. Arcot
will show one method of making it."

Arcot resumed his work, seated now. A formation reached out, and grasped
the lump of platinum still on the floor. Other bars of iron we
