but it must be examined more precisely from the standpoint of nervous 

 physiology. In other words, it needs further experiments with dogs as well 

 as with man. The authors presume that it serves as an important clue 

 for the study of some social behaviour of the conditioned reflex in the 

 nervous system — i.e. from the standpoint of physiology. 



The external induction was determined when a subject was alone as well 

 as when he was in a group of several subjects watching the eater. Table 6 

 shows that external induction of 10 persons averaged 0.17 g when one 

 person was eating chocolate, while, that of one person was —0.22 g when 

 10 persons were eating chocolate. The case of the pickled plum was not 

 the same in principle, i.e. 10 persons averaged —0.11 g when one person
