THE TWO NERVOUS SYSTEMS 367 



functions, of even the systemic nervous system, in that 

 while the control over voluntary muscular activity is lost, 

 the work of the mind, or intellect, can be continued, it 

 may be, with pleasure, and interest. 



For the life, and growth, of the body, during its pre- 

 natal existence, it is not necessary that there should be 

 an actively working systemic nervous system, because an 

 acephalic monster can be developed, and born, alive ; we, 

 however, would reserve, in such a case, the surmise, that 

 the presence of, it may, or rather must, be, some of the 

 basal, cerebral centres, and certainly all the cord, and 

 nerves, with the exception of some of the cephalic, are 

 essential to its evolution, and development besides, it is 

 most likely that the acephalic factors produced their 

 effects, long after the inter-penetration of the fcetal tex- 

 tures, by the systemic nerve elements, took place. 



In the work of development, and organisation, of the 

 embryo, in the growth of the fcetus, in its attainment of 

 the adult condition, and in the maintenance of what 

 constitutes the remainder of the individual life, we claim, 

 that the sympathetic nervature is everything, does every- 

 thing, and supplies everything, for its own wants, besides 

 producing for, and ministering to, every material want of 

 the systemic nervous system, and maintaining the material, 

 and functional, oneness, of the united organisms. There 

 are, thus, only two material entities constituting the 

 highest type of animal organism animated by, or with, 

 that immaterial ego, which is the proud, and distin- 

 guishing, prerogative, and attribute, of, at least, every 

 human creature. 



We shall, therefore, express our strong desire that two 

 distinguishing, and expressive, terms, should be adopted, 

 and used, to express, in less cumbrous fashion, than we 

 have been able to do, with those which have now come 

 to our hand, to describe, so to speak, the dual dynamico- 

 materiality, of man.
