CONTINUOUS STIMULATIONS VERSUS TRANSITIONAL SHOCK 69 



head firmly fixed showed a marked tendency to rotate the disk 

 away from the eye receiving the most light. Inasmuch as the 

 conditions of the experiment were such as hardly to leave any 

 room for fluctuations of light intensity to play any part, the 

 only reasonable interpretation of the results is that they are 

 due to the continuous action of the light.
