We are happy to tell you that G is full of his school work and is very contented with the present curriculum. Inasmuch as he has always complained until this term of lack of work at school and always considered his school work a necessary evil, we feel very grateful to you for his increased interest and happiness.
EARLY MENTAL TESTS
The first recorded measurement of G's mental ability is found in a report from the Educational Clinic of the College of the City of New York, where he had been taken by his father for a private examination. The report is made by Elise S. Mustor, Assistant Director, as of January, 1930. G was then 6 years 7 months old. His Mental Age was found to be 10-9, and his IQ is reported as 163. This report also gives numerous other details which may be summarized in the following tabulation.

LATER TEST RECORDS
1931. G was given a Stanford-Binet examination by Leta S. Hollingworth in May, 1931, within a few days of his eighth birthday. He achieved an IQ of 192. The following comment is included in the record:
The increase over the IQ obtained at the age of 6 is not unusual for a very young, very bright child, although it would be very unusual for an average child. I shall be glad to test G again when he is about 12 years old, and when he is 16 years old. Also his little brother.
