SYSTEMIC NERVINE NUTRITION 171 



economy of the neuronal organisms composing the great 

 neuronal commonwealth, or nerve cell union, which goes 

 to make up the systemic nervous system, as displayed in 

 man, and his more highly organised neighbours in " the 

 scale of being." 



The pabulum thus supplied to the neuronal dendritic, 

 or secretory, processes, is absorbed and passed into the 

 cell body cavities with which they are related, where it is 

 converted into medullary substance, or enters the nuclear 

 body cavities to form the axis cylinder substance of the 

 various axons, or as a final contribution to the economy 

 of nervine nutrition, it supplies the molecular and

atomic wants, of the nucleolar bodies, which latter 

 disposition of the plasma in question, thus constitutes 

 the central and final act of nutritional and formative 

 material organisation, and represents the final, or con- 

 cluding, material contribution to the evolution of that 

 cryptic union of " mind, and matter," which has hitherto 

 defied " the best laid schemes " of the acutest intellects of 

 biologists, physicists, and metaphysicians, alike, to unravel, 

 or fully appreciate. 



The nutritive systemic nervine plasma thus obtained 

 and disposed of is circulated in, or grows along jealously 

 insulated, and continuous, intra-spaces, to the confines of 

 the afferent, and efferent, nervatures, alike, or respectively, 

 where it terminates within, and in continuity with, the 

 structural elements of the skin, and muscles, as a
