NUTRITION, INNERVATION, ETC. 573 



matrix of every tissue of the body, a well-marked circula- 

 tion, through formed or organised vasculatures, con- 

 tinuous the one with the other, takes place, and when 

 they arrive at these tissues their circulation is taken up by 

 cellular agency, and transmitted from cell to cell by 

 connecting cell processes, previous to the passage of 

 anabolised nutriment, the preceding metabolised plasma 

 having been moved on and katabolised, when it is shed 

 into the intercellulo-fibral lymph spaces, gathered into the 

 lymphatic vasculature, and returned into the blood stream 

 to be further dealt with as still useful or altogether 

 effete, while a portion of that arterial circulation is 

 diverted into the pia mater vasculature and deposited in 

 the meshes of the neuroglial matrix as the material for 

 the maintenance of the systemic nervous system, another 

 portion being released to form or become the cerebro- 

 spinal lymph all of which in turn continue circulating 

 until they either are returned directly into the outer 

 world or join once more the great blood circulation to 

 be still further dealt with.
