I then substituted the wooden box used in test IV (text-fig. 

 8) for the wire food box, and turned out the Hght, but a loud 

 noise in the next room frightened the guinea pig. so that the 

 experiment was discontinued 



Aug. 19. The room is again made perfectly dark, the wooden electric bo.x 

 in the labyrinth. Time 3 min. 



The guinea pig knocked against the wire at K (te.\t-fig. 6) which seems to 

 suggest inaccuracy of contact sensations. 



Repeated. Time 2 min. 



The times are rather longer than in the light. I replaced the 

 wire box in the labyrinth and arranged the lighting wire so that 

 when the swinging door was pushed open it would make the 

 current. The contact conditions were then exactly the same as 

 those obtaining in the light. 



Repeated. Time 2 min. 



The wire K was pushed down, which had never happened in the light, and 

 the guinea pig walked over it to get in.

The wire labyrinth was now learned since there were few 

 random moverpents, and though the time was longer than in the 

 light, there was the accuracy of movement showing familiarity 

 with the turns to be made. 



To test whether the successive steps of the path were 

 recollected through immediate contact stimuli, it was necessary 

 to change the character of the contact and leave all the other 

 conditions the same. Only the first reaction after such a change
