memory was so strikingly emphasized as to attract attention 

 one day about three years ago, when he remarked to an older 

 brother who had just tuned a cello that the pitch of the instru- 

 ment differed from that of a few days before — an observation 

 that was verified by appeal to the piano. Since then the boy 

 has been tested, usually for amusement or out of curiosity, 

 some five or six times, but without any records being kept. 

 Composition comes easy to him and he has composed not a few 

 melodious pieces during the last four or five years. 



The notes given in the tests and the observer's judgment are 

 indicated in accordance with a quite simple plan. The notes 

 from and including middle C to its octave above are left un- 

 marked. A tone in the next higher octave is indicated by a 

 single accent mark above the letter, in the second higher by 

 two accents placed above, and so on ; similarly with the lower 

 octaves, except that the accent marks are placed below the let- 

 ter in such instances. The usual symbols for sharp and flat are 

 used after the prescribed fashion. 



The note or notes struck are placed first in the record and 

 are followed immediately by the observer's judgment. In both 

 tests the observer himself was seated with back turned at a 

 distance of about eight feet from the instrument and was look- 

 ing away from it. In other and unrecorded tests at home he 

 has been sent at different times to various places about the 

 house within hearing distance of the piano. The results of the 

 unrecorded tests have been practically the same, as conversa- 

 tion with people present on such occasions has revealed. The 

 uniformity of testimony regarding these unrecorded tests is the 

 reason why more tests were not made by the present experi- 

 menters. 



The first test was made on the observer's piano in April of 

 this year. The results are given in table I. 



Several times the observer was asked not to name the notes 

 but to come to the piano and point them out without striking 

 the keys. It was doubtless an unnecessary precaution. 



A few miscellaneous tests were next made. The observer 



was asked to reproduce, either by whistling or singing, certain 



notes that were named, and thereupon sang or whistled in 



correct pitch, as shown by the piano, the following notes, 



f#', g#, c#/. hb, f. b'" a'', d. 



Following that a simple tune was played on the violin and 

 the key asked for. It was promptly and correctly given. The
