TACTUAL SENSATION IN THE RAT

blind rats were trained to run the maze. These rats had some 

 time previously learned a different maze. They were run in maze 

 I only until each individual had learned the maze for herself. 

 Average results were secured for twenty-one runs, as indicated 

 in table II. These results, while obtained under different con- 

 ditions, bear out, as far as they go, the four conclusions given 

 above, and especially add weight to the contact theory of ac-

quiring the kinaesthetic-organic cues. We also subjoin a typical 

 table (III) of an individual blind rat, which will likewise serve 

 to corroborate our conclusions. 



Moreover, the percentage of contacts as shown in tables II 

 and III does not begin so high as in table I, and throughout 

 the learning process it remains lower. This indicates that the 

 rats were probably influenced by the previous learning of a maze. 

 One of the most obvious factors doubtless was that the blind 

 rats did not have to learn that there was food in the food-box. 

 Furthermore, they w^ere accustomed to running a not entirely 

 dissimilar maze.
