A NEW DEPARTURE IN NEUROLOGY, OR AN ATTEMPT 

 AT THE SOLUTION OF SOME NEUROLOGICAL PRO- 

 BLEMS. 



Cerebro-spinal, or neural^ lymph secretion, circulation, 

 and excretion. 



THE cerebro-spinal, or neural, lymph is a most important 

 element in the economy of cerebral, spinal, and neural 

 structure and function, serving the purposes of intra- 

 cranial pressure regulator, preventer of mechanical friction 

 and concussion, and carrier out of the nervous system of 

 the waste and effete materials resulting from nervine "tear 

 and wear." 



In these, and many other functions, it is continually 

 engaged, so that it is necessarily continually being secreted 

 by the pia mater on the external surface of the brain and 

 cord, and by the choroid plexuses, which are inflections of 

 that membrane into the two lateral, the third, and the 

 fourth ventricles of the brain, circulated through the 

 inter-meningeal spaces, the ventricles of the brain, the 

 central canal of the cord, and the inter-neurilemmar 

 spaces of the whole systemic nervature, with the related 

 sympathetic nervous system, and excreted through the 

 olfactory nerves, the nasal mucosa, the pituitary gland, 

 and united pharyngeo-glossal mucosa, the filamentum 

 terminale of the cord, the coccygeal glomerulus, and 

 related lymph channels particularly, and by the cutaneous 

 sweat glands generally. 



It enters into every space and inter-space of brain, cord,
