"Oh, I don't need it," responded Mr. Fowler. "I was merely trying to find out what your best experiments had been. Have they all been on the physical plane?" "They are all on the physical plane that is to say, on one plane for me. Any 'spirit manifestation, so long as we are what we are, must be an agitation of what we call 'molecules of matter, and is to that extent physical.

From the one standpoint, the ocean is really excited; from the other standpoint, the molecules are moving according to the laws of hydrodynamics. If I want to understand the meaning of this scene every reminiscence of physics will lead me astray; if I want to calculate the movement of my boat, physics alone can help me.

The light is pale blue. Down in the deepest pitchblende mines, where particles of radium have been hidden away since the creation of the world, they are still found shining with their strange blue light. The radium electrons pass through the space which separates every molecule in a solid body from another. The scientific theory is that no two molecules in any body, however dense, actually touch.

The wave theory of sound requires, if we expect to hear sound by means of a C^ fork of 256 vibrations, that the molecules of the air composing the sound wave must not be interfered with in such a way as to prevent them from traveling a distance of at least 1/50 to 1/1000000 of an inch forward and back in the 1/256 of a second.

It is not my purpose to discuss the truth or falsity of the atomic theory, or the relation of mind to the movements of molecules in the brain; I simply point out the fact that this is virtually an old hypothesis; and I leave each one to judge how great a degree of light it has shed upon the path of human life in the ages of the past, how far it availed to check the decline of Greece and Rome, and how much of real moral or intellectual force it has imparted to the Hindu race.

The general effect is similar to that produced by two ships having a head-on collision at ten miles per second. Anything touched by the beam is broken by its own molecules, twisted by its own strength, and crushed by its own toughness. Nothing can resist it.

A still higher rate of vibrations of a somewhat different type will separate these molecules into their constituent atoms.

"If Jacques Loeb* is right, that action of the iron molecules is every bit as conscious a movement as the least and the greatest of our own. There is absolutely no difference between them. "Your and my and its every movement is nothing but an involuntary and inevitable reaction to a certain stimulus. If he's right, then I'm a buttercup but that's neither here nor there.

Arcot raised his molecular pistol, a blue green ray reached out, and the rock suddenly was black. It settled swiftly down, and a slight depression was the only evidence of the terrific action. Arcot walked over the now cool rock, cooled by the action of the molecular ray. In driving the molecules downward, the work was done by the heat of these molecules. The machine was frozen in the solid lava.

When a tuning fork, for example, is caused to vibrate, it is assumed that the supposed molecules in front of the advancing fork are crowded closely together, thus forming a condensation, and on the retreat of the fork are separated more widely apart, thus forming a rarefaction.
