etheric molecule revolved so rapidly that, thin as it was in its
shell, it gave us the dust out of which worlds were made. There
is one fatal error in this idea, although it is held even now by
many. It is based entirely on gravity, and gravity is alone
considered in its problems. There are two great forces in the
universe, not one, as many scientific people fail to remember
--Gravity and Apergy, or the centrifugal and centripetal forces.
The pull in is and must be always balanced by the pull out.
There is in the universe as much repulsion as attraction, and the
former is a force quite as important as the latter. The bubble's
speed kept increasing until apergy, the tendency to fly off,
overcame gravity, and it ruptured.

"Professor Lodge failed to take into account this apergic force,
this tendency to fly off, when he gave such high revolutionary
speed to the etheric molecules, a speed in which apergy would
necessarily exceed gravity. The failure to take apergy into
consideration has been the undoing of many physicists.

"Today we know that the ether is matter, the same as our own,
only finer and rarer and in much more rapid vibration. We know
that this ether has its solids, liquids and gases formed from
molecules of its atoms, even as our own are formed. We know that
its atoms combine as ours do, and while we have but eighty
elementary combinations, it must have more than double the
number. We know that every form and shape and combination of
these elements from this plane flows from inherited tendencies
having their root in the etheric world.

"The two worlds are one world--as much at one with ours as the
