Then, since they want the internal movements of this brain to create or determine the representation of the whole material world an image infinitely greater than that of the cerebral vibrations they maintain that these molecular movements, and movement in general, are not images like others, but something which is either more or less than an image in any case is of another nature than an image and from which representation will issue as by a miracle.
Soddy asks if the physical distinction between living and dead matter begins in the jostling molecular crowd begins by the crowd being directed and governed in a particular way. If so, by what? Ah! that is the question. Science will have none of it, because science would have to go outside of matter for such an agent, and that science cannot do.
If the pressing hand has a twisting motion, the book will be warped. Any solid may be thus sheared or warped, but neither liquids nor gases can be so affected. Molecular cohesion makes it possible in the one, and the lack of it, impossible in the others. The solid can maintain such a deformation indefinitely long, if the pressure does not rupture its molecular structure.
A molecular reached down from somewhere in space, hit the ray screen of Ortol, which the Thessians had attacked for hours, and the screen flashed into sudden brilliance, and disappeared. The ray struck the Thessian fort, and the fort burst into tremendous opalescence, while the invisible barrier the ray had struck was suddenly a great sheet of flaming light.
This theory of molecular force, as extended to vital physics in the force-doctrine of life, is irreconcilably at war with the principal phenomena of life, and should be classed with the other undiscovered correlates of force, which Professor Beale speaks of as "the fictions of a mechanical imagination."
The skin of the handsome caterpillar thus has two sorts of coloured patches. Those of an intense black may be likened to dyers' products: they are completely impregnated with the colouring matter, which is part and parcel of the molecular constitution and cannot be isolated by the nitric solvent.
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.
In such a case an additional charge is required only when some of the original charge is taken away, escapes. This is Static electricity; the same as the other, but in theory differing in application. The molecular theory is, unquestionably, tenable under present conditions. It is that to which science has attained in its inquiries to the present date.
The fact that steam and snow can be changed back into water, and by simple manipulation cannot be changed into any other substance, finds, as we now believe, its true explanation in the fact that the molecular structure, as we phrase it that is to say, the ultimate particle of which water is composed, is not changed, and this is precisely the explanation which Anaxagoras gave of the same phenomena.
In the case of gases, a molecular theory has been developed by Clausius and others, capable of mathematical treatment, and subjected to experimental investigation; and by this theory nearly every known mechanical property of gases has been explained on dynamical principles; so that the properties of individual gaseous molecules are in a fair way to become objects of scientific research.
