nervous matter. By reason of its extreme mobility 

 this great mass of nerve tissue, permeating every point 

 of the organism, is in perpetual motion. This isomeric 

 molecular motion constitutes the consciousness of the 

 individual, keeping it in perpetual unity, with the 

 same energy, or force, which produces molar motion, 

 in the environment the two being differentiated 

 phases of the persistence of force. 



Whenever there is an impression made on any of 

 the organs of the senses, of touch, sight, hearing, 

 smelling, or tasting, it is conveyed inwardly, along 

 the receptive nerves, by what is called isomeric molecu- 

 lar motion; that is, there is a re-arrangement, and 

 more or less destruction, of the little invisible particles 

 called molecules, which make up the substance of the 

 nerve, through its whole length, or through a sufficient 

 length, to convey the impression to one of the ganglia. 

 These ganglia, composed of yet more mobile matter 

 than the nerve threads of conveyance, add to, co- 

 ordinate, and discharge the motion along effector, or 

 motor nerves, and thus produce the phenomena of 

 bodily motion, and all the phenomena called psychical. 

 The ganglia acting, apparently, like galvanic batteries 

 of electrical energy, send the impression, if need be, 

 by the molecular motion of motor nerves, to exhaust 

 themselves in muscular action. But, if the sensations 

 are of a nature to require brain action instead of 

 muscular action, then the sensory energy, coming from 

 the environment, is conveyed to the central nervous 

 organ, called the brain, and there by molecular and 

 chemical process, it is co-ordinated into one of the 

 phases of psychic phenomena, called perception, image, 

 emotion, conception, reason, memory, or will. The 

 individual sensations are co-ordinated with each other,
