But to get at this result we neglect two important factors. We do not take into account, in fact, the attraction which the molecules must exercise on each other. Now, this attraction, which is never absolutely non-existent, may become considerable when the molecules are drawn closer together; that is to say, when the compressed gaseous mass occupies a more and more restricted volume.
Electrons, very much smaller than atoms, can move through the structure, considerable to them, which is constituted by the atom from which they have just been detached. They may be compared to the molecules of a gas which is enclosed in a porous body.
This conception of heat as the rapid change in the form of atoms and molecules, due to their elasticity, is a phenomenon peculiar to matter. It implies a body possessing form that may be changed; elasticity, that its changes may be periodic, and degrees of freedom that secure space for the changes. Such a body may be heated.
We give it in the exact phraseology employed by Professor Bastian: "Living matter is formed by, or is the result of, certain combinations and rearrangements that take place in invisible colloidal molecules a process which is essentially similar to the mode by which higher organisms are derived from lower in the pellicle of an organic infusion."
Usually they deform the mental and spiritual estate. We should have many acquaintances or none. When two men begin to "tell each other everything," they are hiking for senility. There must be a bit of well-defined reserve. We are told that in matter solid steel for instance the molecules never touch. They never surrender their individuality.
There were a couple of long-chain molecules that he could only believe after two re-examinations and a careful check of the machine, but with the help of the notes he could deduce how they had been put together. They would be the Ingredient Alpha and Ingredient Beta referred to in the notes.
I will not stop to ask how if reproduction of lost limbs be due to polarity of the molecules, in other words to the direction which in the circumstances of the case the molecules are bound to take, and if the polarity of each particular set of molecules be impressed upon them by the group formed immediately previously how it is that the group terminating the docked stump of a limb, which group is represented as commencing the work of reproduction, imparts a different direction or tendency to the fresh molecules of nourishment that are supplied to it, from that which it has been accustomed to communicate to previous molecular supplies.
He held that all space was filled with molecules of matter in a state of rapid motion in every direction. These molecules were subject to gravity and endowed with properties or forces.
Greater than his adventure in the world of thought was his love-adventure. The world itself was not so amazing because of the atoms and molecules that composed it according to the propulsions of irresistible force; what made it amazing was the fact that Ruth lived in it. She was the most amazing thing he had ever known, or dreamed, or guessed. But he was oppressed always by her remoteness.
But this is overlooking all generic distinction in respect to processes or modes of action. Crystals are inorganic matter which form, do not grow. They are mere symmetrical arrangements, not organic growths; and are produced by some law akin to chemical affinity, acting on the molecules of their constituent mass. They possess no vital function. They show no beginning or cessation of life.
