HOGG: ABSOLUTE TONE MEMORY. 117 



In closing, a few statements are made by way of addition 

 and partial summary. For our observer the difficulty of iden- 

 tifying a single tone is scarcely harder in one region of the 

 piano scale than another. But there is a decided difference in 

 ease of analysis according as there are high or low complexes 

 of tones. In the third octave below the mental separation of 

 two notes was not attempted, the remark being made, ''It's 

 such a jumble, I can't remember," while in the third above the 

 identification was made with accuracy and without a noticeably 

 great amount of concentration. Images from the organs of 

 utterance seemed to play no part whatever in his recall of 

 tones. Sound images apparently furnished exclusively the ma- 

 terial used in all the judgments. Upon being questioned as 

 to his method of identification and of reproduction the observer 

 said he "just heard the tones in his head and told in that way." 

 Of a piece of music recently purchased for him he said he had 

 played it off "in that way" before touching a finger to the 

 piano. His introspective competency was greater than was 

 expected.
