average number of errors per animal was 20% less than in the 

 normal maze but the animals made two and one-half times as 

 many errors as their brothers in the experiment where the trail 

 was in the true path. The learning time was actually shorter 

 than in Experiment 1. There is so little difference, however, 

 that it may be a matter of chance. The conditions, as a whole, 

 were very favorable for learning as compared with the normal

maze and scarcely less so than those in Experiment 1, where 

 the trail was in the true path. It seems fair to conclude, there- 

 fore, that these conditions did affect the accuracy, and in general 

 favorably, but that there was a variableness in the final reactions 

 which will require explanation. 



3. Comparative Speed 

 The speed in this maze was quite comparable with that in the 

 normal maze except when the rats were in the cul de sacs and,
