ON CEREBRO-SPINAL, OR NEURAL, AND H^MAL LYMPH 

 IN COMPARISON WITH EACH OTHER, AND IN THEIR 

 MUTUAL RELATIONSHIPS. 



WHILE lymph is regarded as a generic term, embracing 

 all the varieties of that fluid found in the lymphatic 

 vessels, the cerebro-spinal cavity, and the various ' ' shut 

 sacs," as they are commonly called, which are to be found 

 throughout the body, as well as in the inter- and intra- 

 textural spaces of the connective and more organised 

 tissues and organs, the liquor sanguinis being truly lymph, 

 may be looked upon as the source from which all lymph 

 is originally drawn, and the great storage depot, so to 

 speak, into which it primarily and secondarily finds its 

 way, because into it comes the chyle, fresh from the 

 digestive organisms, with the lymphatic fluid proper, 

 collected by the lymphatic vascular system throughout 

 the body, to be emptied into the great blood stream. A 

 great exception to his rule, or manner of lymph disposal, 

 however, must be claimed, according to our views on the 

 subject, for the distribution and direct final elimination of 

 a great proportion of the cerebro-spinal lymph, inasmuch 

 as it is walled off, and kept regionally separate from the 

 lymphatic circulation proper by its own containing spaces 

 and vessels, with the exception of its distribution to the 

 muscular structures, where it secondarily or finally becomes 

 continuous with the systemic or haemal lymphatic fluid and 

 the lymphatic circulation proper, and where, consequently, 

 its sometimes pathological or pathogenic condition is liable 

 to disturb the physiological lymphatic equipoise, and to
