With the exception of the last three comparisons, which are in- 

 serted in this place because they were made in immediate connec- 

 tion with the preceding ones in the same table, the experiments 

 whose results are given in Tables VII. and VIII. involve a more 

 serious difficulty in estimation than do those previously consid- 

 ered; since, instead of having to decide merely which of two notes 

 is the higher, it is necessary to determine the musical relation of 

 the various notes in the set sounded. Nevertheless, even with the 

 shortest observed duration of the sound, the uniform preponderance 

 of correct over incorrect or doubtful judgments is altogether too 

 great to be the result of chance. 



Moreover, even when the ability to determine which was the 

 higher of two notes was lost, with briefer durations of the sound 

 than those recorded in the tables, there was always a clear difference 

 in the pitch of the two notes; that is, they did not seem like the 

 same sound. 



It will of course be observed that, with the method used by us,
