continues, until the whole combined areas have become 

 one for material, and functional purposes, and a complete 

 human organism evolved. 



The nerve cell as it develops from the spongioblast takes 

 unto itself structural characteristics, material, and dynamic, 

 by which it is enabled to traverse, and functionate, the 

 embryonic elements, to the extent permitted to the 

 systemic nervous system functionally to affect the meso- 

 and hypo-dermic areas, while it throws out dendritic 

 processes, through which it texturally supports itself with 

 nourishment from the neuroglial matrix, and develops an 

 axonal process, or processes, through which it effects a 

 union with distant structures, such as the muscles, and skin, 

 at the same time evolving within itself a nucleus, and 

 nucleolus, which perform the specific functions of inner- 

 vation, and harmonise, and co-ordinate, the working of the 

 materio-dynamic agencies of the systemic nervature, within 

 itself, and in union with the sympathetic nervature. 



The formation of each neuron is followed by its dedi- 

 cation to a particular work in the economy of innervation, 

 either as sensory, motor, or psychic ; or as linking up the 

 various forms of neurons within the systemic nervature, and 

 combining in a composite, and co-ordinated, whole, the 

 dual nervatures, systemic, and sympathetic. 



The completed nervous system is, therefore, a compound 

 of innumerable neurons of differing functional ability, 

 according to the nature of the particular locale occupied, 

 and the particular neuronic work entailed by that locale ; 

 thus they may be (a) receivers of sensory impression ; (b) 

 communicators of nerve impulse ; (c) participators in 

 psychic cerebration, or, (d) vehicles of exchange in the 

 balancing of the systemic, and sympathetic, nerve energy. 



Each neuron secretes, and grows upon, neuroglial 

 plasma, and, contrary to current belief, excretes, or passes 

 that plasma, along its axonal process into the texture with 

 which it is functionally, and histologically, connected ; 

 thus the two great divisions of the systemic nervous 

 system terminate in, and become continuous with, the 

 proper elements of the skin, and muscles, respectively, 

 and thereby effect both a material, and dynamic, con- 

 tinuity, and oneness, between the proper neuronal struc-
