were, written out from the telegraphic symbols into the hand- 

 writing of the clerk at the receiving station. 



Another tekmerion reaches me from the onto-fire through my 

 sense of warmth, and another through my ears. These messages 

 travel to me by other and very different lines of telegraphic com- 

 munication between that auto and me. They also undergo com- 

 plete transformation before they reach their destination. This is 

 in fact true of all the communications made to me by sense- 

 compelling auta. 



The tekmerion being the ultimate form of the message, any 

 change which it undergoes indicates that a change has taken place 

 either in the sense-compelling auto, or somewhere along the line 

 of communication. If, for example, I am looking at a building, 

 the tekmerion which thereupon comes into existence, viz. : my 

 visual perception of the building, will change — 1°, if a window be 

 thrown open. Here the change in the tekmerion is caused by a 

 change in the auto. 1 Or 2°, if the building is seen by a red stron- 

 tium light, instead of by daylight. Here the change has been in 

 the way the sense-compelling auto has been affected by other 

 sense-compelling auta. Or 3°, if I direct my eyes in succession to 

 different parts of the building. Here the change has been in the 

 channel of communication. Or 4 C , if I walk round the building and 

 view it from different sides. Here again the change has been in 

 the channel of communication. Or 5°, if by drugging myself 

 with santonin I become temporarily colour-blind. Here the 

 change has again been in the channel of communication, the 

 repeating station, my eye, having been so altered that it now 

 translates the message it receives differently before sending it 

 forward. 



The enumeration of these particulars is chiefly of use here in 

 order to lead up to the remark that, owing to past experience and 

 an inherited aptitude, my mind, aided by its synergos, has become 

 extraordinarily expert in distinguishing in such cases ; so much so 

 that I can usually tell instinctively, *. e. at once and without any 

 effort (that falls within my consciousness), which of the perceived 

 changes in the tekmerion indicate changes in the originating auto,

 significations that the names used are to be understood. (See Diagram III., p. 486.)
