intermediation of impressions from the Special Senses, 

 the centres of which have been awakened and rendered 

 more receptive by being brought into relation with distinct 

 though ' unconscious ' Visceral Impressions. 



It would seem, indeed, from some observations which 

 have been already made, that in many cases of Hemi- 

 ansesthesia, the viscera remain at least as tender as ever 

 under firm pressure upon both sides of the body ; and 

 this, of course, would indicate that the cerebral channels 

 for these impressions do not intermix, in the region of 

 the * internal capsule,' with those of other modes of sen- 

 sibility. 



And, though their so-called * Centres ' may also be dif- 

 ferently situated, it is pretty certain that Visceral Im- 

 pressions must either radiate into, or be brought into 

 intimate connection with, some parts of the province of 

 each of the Special Senses, since they all so frequently 

 interact in the manner already referred to. The inter- 

 action does not, however, only take place in one direction. 

 There is on the part of the ' Sexual Appetite,' as Prof. 

 Bain points out, "a, many-sided susceptibility to inflam- 

 mation, through all the senses, through the trains of 

 thought, and through emotions that are not sensations.'* 

 To a less extent a similar ' inflammability ' by means of 

 sensorial impressions also obtains in regard to the ' Ap- 

 petite for Food.*
