THE LEARNING OF A MAZE BY GOLDFISH 255 



The physiological limit for the running of the maze when 

 daily trials were given was, for Group I, 2 minutes reached on 

 the thirty-sixth trial; for Group II, one minute on the twentieth 

 trial; for Group III, one minute on the thirty-sixth trial. The 

 habit was fairly well retained after 13 days lapse of practice. 



The senses of sight and touch were instrumental in the initial 

 steps of the habit formation but later were superseded to a great 

 extent by kinesthesia.
