tive condition leading to rest more or less complete. For 

 when satiety is attained hunger has no existence, and im- 

 pressions from that source are null and void, and with that 

 a general tendency to quietude and inaction. 



If the seven senses are more carefully considered from 

 another point of view, they naturally divide themselves into 

 three body senses, or the somatic senses, and four accessory 

 or supplementary senses, orthe 7rapairio$, or the paraitic senses. 



The somatic senses are touch, weight, and hunger, and 

 give us a knowledge of self, or supply to us the condition of 

 consciousness known as the ego or conscious ego. 



The paraitic senses are supplementary to and servants of 

 the somatic senses to a greater or less extent, and include 

 the senses of sight, hearing, smell, and taste. 



These last-named senses are viewed as having peculiar 

 apparatuses of metamorphic sense differentiation, distinct 

 from the differentiations of the somatic senses in many and 

 important particulars. 



The paraitic senses are, saving in the sense of taste, 

 elongated limbs, having special apparatuses for communi- 

 cating afar off the conditions and circumstances of nature, 

 through fixed and definite media, so that all necessary prac- 

 tical knowledge is supplied of external surroundings, by a 

 new device in adaptation of limbs or indirect tactile touch, 

 external to and beyond the range of the somatic senses. 

 But the conscious ego (formed by the somatic senses) would 

 be little else than a cipher in the world, with all its powers of 

 locomotion, prehension, and satiety, unaided by the accessory 

 senses, or servants to the somatic ones, yet with their aid 

 the servants will carry out more completely what by himself 

 the master cannot accomplish ; and one of the main points 

 that servants can do for a master, which the master alone 

 cannot do, is, that through representative servants he can be 

 in two or three places at one and the same time ; so we can
