ON WHAT DISTINCTNESS OF THE SYSTEMIC NERVOUS 

 SYSTEM IMPLIES. 



DISTINCTNESS of the systemic nervous system, within 

 its organic textural surroundings, implies, amongst other 

 things, only comparative, or practical, distinctness for we 

 are not warranted in making the term absolute of its 

 organised nervous texture, as well as of its lymph, or 

 peri-nervine fluid, and hence the removal of the latter, 

 from within the nervine precincts, without admixture 

 with the surrounding systemic, or haemal, lymph, is 

 uniformly effected, save when the efferent nervature 

 discharges its contents, fluid, and plastic, into the muscu- 

 lar areas, and substance, and thence into the systemic, 

 or hasmal, lymph, circulation. This discharge, so long 

 as the nervine lymph is maintained in a state of purity, 

 chemical, and physiological, is accomplished, without 

 pathological incident, so soon, however, as it betrays a 

 departure from that condition, tell-tale sequences of 

 morbid events, begin to manifest themselves, in accord- 

 ance with the nature of the morbid interference, or diseased 

 process, which often culminate in the production of a 

 definite morbid condition, as it is known to the, diagnos- 

 tician, and nosologist. To the keen observer, therefore, 

 is thus afforded most valuable information, and circum- 

 stantial evidence, for his guidance, in the choice of 

 treatment, as well as, for the satisfaction of his scientific 

 amour propre. 



The afferent, sensory, or cutaneous, peripheral nerva- 

 ture, possesses outlets, by which the nervine lymph, or
