ON CIRCULATION AND NUTRITION 179 



thelial linings of the blood vasculature, and sympathetic 

 ganglia, and the nerve cells proper of the systemic nervous 

 system, and conveyed by nutritive circulation, along 

 successive histological processes, or lines, and linked cells, 

 to every texture requiring nutritional supplies. From this 

 it follows, that every cell must belong to one, or other, of 

 the nervous systems, and that, consequently, all nutritive 

 processes are the work of, one, or the other, system, hence 

 nutrition is a dually performed function, according to the 

 dual division of all cells, into, sympathetic, and systemic, 

 respectively. Thus, the sympathetic, nourishes, directly 

 from the blood, every texture of the body, save those 

 dependent on the systemic nervous system, besides laying 

 down in the matrix of the neuroglial substance of the 

 systemic nervous system, the " prepared raw material," or 

 pabulum for the nutrition of that system, while the 

 systemic nervous system nourishes, in like manner, every 

 texture directly continuous with itself, on both its afferent, 

 and efferent aspects. 



The process of nutrition being, thus, effected through 

 cell agency, along communicating histological processes, or 

 connective fibres, porous enough to permit of plasmic 

 circulation within them, and surrounded by a, protective, 

 and insulating, fluid, or lymph, containing "normal saline," 

 or its equivalent, in both its sympathetic, and systemic, 

 varieties, a continually forward, and unmixed, distribution,, 

 of nutritive material is obtained which obviates the oc- 

 currence of regurgitation and consequent autotoxis, and 

 eventuates in the metabolic phenomena constituting the 

 act of nutrition, and including both integration, and dis- 

 integration. 



The act of nutrition varies in extent, with the needs of 

 the tissue, or unit of texture, undergoing nutrition, and is 

 essentially one of supplying tissue molecular, or atomic, 

 wants, due to impaired material continuity, from the effects 

 of functional, or materio-dynamic, tear and wear, and the 

 natural katabolic denudation ever present in all organised, 

 as well as unorganised, substances. 



Nutrition, thus, constitutes the central, and ultimate, 

 vital distribution, aiid incorporation, of the alimentary 

 materials supplied for the body's upkeep waste, and
