THE SYSTEMIC NERVOUS SYSTEM 369 



fluid, is thrown out of the system, without the possibility 

 of its admixture, except in somewhat rare pathological 

 states, with the systemic, or haemal, lymph, or the blood 

 circulation : diseases, therefore, occurring within this 

 area, begin, and end, as purely nervine, and cutaneous 

 morbid entities, being initiated, as a rule, by sepsis of the 

 cerebro-spinal lymph, and closed by the excretion of the 

 resulting bacterial organisms, with their resulting toxins, 

 through the various cutaneous, and other nervine emunc- 

 tories, where their nature can be read, in characters 

 impressed on the implicated areas, by varying modes of 

 eruption, and outfall disposals. 



On the contrary, the efferent, or motor, nervature, 

 terminating directly in the musculature of the body, 

 throughout its entire extent, exudes, or excretes, into 

 that musculature, the entire lymph, passed along its 

 peri-neural inter-spaces, or lymph paths, which, in morbid 

 conditions of that fluid, must necessitate the production 

 of specific morbid effects, in the form of morbid entities, 

 determined by the nature of the particular materies morbi, 

 besides the occurrence of morbid processes in succession, 

 throughout the entire " course of circulation," followed 

 by the lethal, and malign, viri, and "sequences of events," 

 characterising much of the disease incident to this mixed 

 region, before elimination, or neutralisation, of the tainted 

 neural lymph can be effected, by haemal, or systemic, 

 agencies. 



As types of two classes of disease, thus arising, we 

 would mention Herpes Zoster, and acute rheumatism 

 the former, representing a disease beginning, and ter- 

 minating, with, and comprising the stages of invasion, 

 occupation, and abandonment, of a limited portion of the 

 neural, or cerebro-spinal, lymph, area, the latter repre- 

 senting, a more or less, wholesale invasion, and occupation, 

 of the motor areas, together with the extra-nervine areas, 

 to which it is related, and which lie between it and the 

 systemic lymph circulation, along which combined tracts of 

 circulation, morbid action may prevail, before the cessation 

 of its symptoms can ensue, or its evil results subside. 



This much applies to the lymph disposal, only in its 

 aspect of distinctness, from the surrounding haemal lymph
