In March, 1924, at the age of 9 years 4 months, F was given a mental test, using Army Alpha, by L. M. Potter. He was then in Grade 6B, P.S. 14, Manhattan. His score was recorded as 124 points. But there is also a copy of an Army Alpha Test, Form 7, given F in the fall of 1924 upon his entrance to P.S. 165, on which the score is 163 points. On April 14, 1924, at the age of 9 years 5 months, F was given a Stanford-Binet test by M. V. Cobb, in P.S. 165, Manhattan. His Mental Age shown at that time was 15-2, and an IQ of 162 was reported. Strength of grip measures were also recorded as of May 15, 1924. These were made by Leta S. Hollingworth, three trials for each hand. The records were (median of three), right, 10.5; left, 9. On April 22, 1925, at the age of 10 years 5 months, F was given a Stanford-Binet examination by Leta S. Hollingworth as a demonstration before a class of 60 adults. His Mental Age was 19-0, and the IQ is recorded as "over 182, unmeasured by the scale." On May 8, 1926, at the age of 11 years 6 months, F was again tested with the Stanford-Binet [[by L. S. H.]]. He passed at this time all the Superior Adult tests and was thus unmeasured. He was at this time in his first year of senior high school. January 7, 1933, at the age of 18-2, while a college freshman, his score on Army Alpha, Form 8, was 198 points. _Music tests_. F showed no active musical interests but became very fond of listening to good music, being particularly fond of string quartets. As was the case in every field to which his interests turned, he quickly acquired a fund of information about it which he took pleasure in exhibiting. F was given the Seashore Music Tests four times [[by L. S. H.]] over a period of 11 years. Perhaps the record of these successive examinations will have some intrinsic interest, and such a tabulation is here provided.

After six months' acquaintance, on September 14, 1924, when F was about 10 years old, he was rated by Leta S. Hollingworth for various estimated traits on a 7-point rating scale as follows:
