ponent part, the distanoe run is never projortional to the time 

 spent, since if the rat does not refuse to run altogether after 

 several vain efforts to reach the center, it will make frequent 

 halts at^the radial stops and at the entri-nce to the maze. It 

 appears that we have here additional evidence for considering 

 the distance as a more accurate measure of the learning process 

 than the time. 



Accorling to the averages which appear below, the females 

 of this groujj are superior to the males in number of trials 

 required to learn, and in final efficiency (absolute time), but 

 inferior in total time consumed, total distance covered, and 

 speed attained throughout the learaing process, so that on 

 the v.'hole the males may be considered as slightly superior to 

 the females.

Males 32 5.7 sec. 213 min. 277.1 m. 21.6 cm. per sec, 

 Females 29 5.6 " 232 " 267.8 " 15.2 " " 



The time variation of the males is leas than that of the 

 females, while the reverse relation ejiiats regarding the distance 

 variation^ as shown below:
