Thus in the advance of annelids to insects the muscular system increases in relative bulk, and absolutely in complexity. But a change or increase in the muscle must be accompanied by corresponding changes in the motor-nerve fibrils; and these again would be useless unless accompanied by increased complexity and more or less readjustment of the cells and fibrils of the nerve-centres.
Massillon's injunction, "Look thou within," does but discover to our view in nerve-centres, in emotional or in instinctive tendencies, hieroglyphics graven by long vanished ancestral generations. But Nature, to guard man from despair, has fashioned him a contemporary of the remotest ages.
The nerve-centres, the source of the leg-movements, are situated a little above the wounded point, but the back-to-front direction of the sting makes it possible to reach them. This last wound results in the paralysis of all the eight legs at once. To enlarge upon it further would detract from the eloquence of this performance.
My friend was nonplussed, but what had happened was this: on my first speaking the impulse of the voice had fallen upon his ear and started a nerve-wave which had struggled up as far as the lower apparatus at the base of the brain, and, passing through this, had probably even reached the higher nerve-centres in the surface of the cerebrum, near to which consciousness resides, but not in sufficient force to arouse consciousness.
But, mark you, this intelligence in the cells and nerve-centres of your body is negative to the Central Intelligence in the brain the controlling centre the "I Am" and is affected by suggestions, beliefs and thoughts in your brain. All you have got to do is to avoid projecting negative thoughts from your mind and let it alone.
Professor Bain, another eminent authority, tells us: "The structure of the nervous substances, and the experiments made upon the nerves and nerve-centres, establish beyond a doubt certain peculiarities as belonging to the force that is exercised by the brain.
By and by the piece is so well known that it is played even when the attention is directed to some other subject; that is, the act of playing has been repeated until the lower nerve-centres, which preside over the movements of the fingers during the playing, have been so impressed that when once the impulses are started they flow on uninterruptedly until the whole set has been gone through and the piece of music is finished.
Gerty knelt beside her, waiting, with the patience born of experience, till this gust of misery should loosen fresh speech. She had first imagined some physical shock, some peril of the crowded streets, since Lily was presumably on her way home from Carry Fisher's; but she now saw that other nerve-centres were smitten, and her mind trembled back from conjecture.
The number, arrangement and degree of mutual independence of the nerve-centres guide the sting; the anatomy of the game, rather than its form, controls the huntress' tactics. Let me mention, before I dismiss the subject, a superb example of this marvellous anatomical discrimination.
Here are no lancet-pricks regularly distributed; on the contrary, the operating-method betrays a lack of symmetry which would be inconceivable, if the organization of the patient did not serve as a guide. The Tachytes therefore knows where her prey's nerve-centres lie; or, to speak more correctly, she behaves as though she knew.
