 these same two minds could have two bodies with sets 

 of senses complete, so that each might be able to follow 

 its own line. I envied the chameleon just then a 

 strange creature which is said to change its colour ac- 

 cording to its surroundings. That, however, is merely 

 a physical condition, one which it shares with certain

 psychology, is the divisibility of its mind, the faculty of 

 being two persons in one body, each thinking and

 of his brain are working separately, each occupied with 

 its own problem. It may be seen in his eyes minute 

 round lenses mounted on swivels, or small fleshy or 

 rubber processes, capable of being elevated or de-
