According to Schnitzels recent investigations, both forms of processes 

 of these central ganglion cells (fig. 30-8) possess a fibrillated texture, more 

 apparent in the axis cylinder processes (a) than in the protoplasm ramifi- 

 cations (6), in which latter a granular interstitial substance is present iu 

 considerable quantity. All these primitive fibrillse may be followed up

into the body of the ganglion cell, and may be easily recognised there, 

 especially in the external portions, imbedded in a finely molecular 

 mass. Their course is a complicated one, sometimes diverging on 

 entry, and sometimes giving rise to an interlacement of crossing and 

 re-crossing fibrillre. Connection with the nucleus or nucleolus does 

 not take place. Whether we have here the true origin of the primi- 

 tive fibrillse, or whether the latter merely undergo a re-arrangement 

 here, that is, that, arriving from remote localities through the various
