ing signs of mental operations underlying the displayed activi- 

 ties. When ar was rapped, br, a-, dr and er contracted 

 respectively instead of remaining motionless until each received 

 individual blow. Apparently from previous experience, the 

 organism foresaw, when ar was hit, that the succeeding seg- 

 ments were doomed to the same unpleasantness, so a total 

 contraction was signalled to all on one side. 



The fourth series of experiments was conducted after the 

 chrysalis had been left undisturbed for a number of days. 

 The blow was not, as in former experiments, given at either 

 ra or la, but at the apex. The change of starting points was 

 made purposely to give the organism a larger field for exercise 

 of higher mental activities than hitherto. 



Shortly after the experiment was resumed, the organism so 

 readily recalled the experiments of the 'previous days that 

 when re or le (at the apex) was touched, the succeeding seg- 

 ments on either side (not both) contracted successively. After 

 a continuation of similar experiments, the organism learned to 

 contract both sides of segments simultaneously in response to 

 impulse starting from any point of the body. 



Hopes of further experimenting were frustrated by untimely 



extinction of life.
