EXTRACT XXXIV. A. 



ON THE DIVISION OF THE "NEURAL WORK" AS 

 EXEMPLIFIED IN "THE NERVOUS SYSTEM" IN 

 ITS RESPECTIVE PARTS OF SYMPATHETIC AND 

 SYSTEMIC. 



IN a previous treatment of this subject, we endeavoured 

 to make plain the respective roles played by the two 

 systems. Further study of the subject, however, compels 

 us to amplify these remarks, in order to make plainer 

 our views on the subject, and to afford, to a fuller extent, 

 the materials necessary, for laying the foundation of a 

 more exact neuro-psychology, than we have yet been able 

 to formulate. We would, in beginning these supplemen- 

 tary statements, again bespeak, for the sympathetic division 

 of the nervous system, a larger place in the scientific field 

 of neurological phenomena, every day brought into re- 

 search prominence, by the army of investigators, now 

 spread over, we may say, the whole world, and a fuller 

 treatment, than it has yet obtained, so that its proper 

 value, to the science and art of medicine, may be ob- 

 tained, as we are firmly convinced that this can only be 

 attended by unmixed advantage, both to the progress of 

 abstract science, and . the enlargement of our powers, of 

 healing and amelioration. 



All vegetable life is due to a vital mechanism, actuated 

 by the equivalent of that neuro-dynamic agency, which 

 is entrusted with the administration of sympathetic nerve 

 energy, and the maintenance of lower animal life exclu- 

 sively, and which shares, with the systemic nervous 

 system, the maintenance of life, throughout the higher 

 animal world, and, therefore, in man, par excellence.
