hence which may be further regarded as the proper nerve 

 substance, or the substance the molecular affection of which 

 conveys those impulses called nervous. 



We shall now ask ourselves the question, and what 

 here seems to us to be the question of questions, viz. : 

 Whence and whither are these nerve impulses most pro- 

 bably conveyed ? and we think there can only be one 

 answer given, if what we have here stated be true. The 

 nerve impulses are conveyed to the nucleoli of the nuclei 

 of the cells, the only structures of the neurons remaining 

 undescribed and unaccounted for, through the axis- 

 cylinders of the sensory nerves from their " nerve 

 endings," on the one hand, and from these nucleoli 

 themselves, which initiate and determine them and pass 

 them outwards through the various motor nerves to their 

 " nerve endings," on the other. 



The nucleolar structures of the neurons of the brain 

 proper, or cerebrum, and it may be of some of the higher 

 related basal centres, thus become, and we contend must be 

 recognised as, what we are in search of, viz. the Dwelling- 

 place or Home of the Ego. 



The nucleoli of the cerebral and higher basal neurons 

 must thus be regarded as the most highly functioned and 

 organised structures of the body, as the most deeply 

 sensitive, receptive and retentive, and consequently as the 

 most finally poised and explosive. Hence, emotion, voli- 

 tion, and "staying-power" in the healthy, and the "nerve 

 storms " in the diseased. 



In arriving at this conclusion we have guided ourselves 

 by a process of structural elimination, and in searching for 

 the various possible " dwelling-places of the ego " to be 

 found throughout our bodies, we first of all eliminated 

 the organs and structures external and inferior to the 

 brain ; and in the brain itself we have, in a like a ner > 

 eliminated the neuroglial substance proper, as only afford 

 ino- the soil on, and in, which the neurons, of which t 

 higher organisms of the nervous system are composed 

 grow, and from which they develop and derive continue 

 sustenance. These two eliminations leave us with th 

 neurons, the consideration of which in their comple 

 details in turn leaves us with, after the elimination of the
