In addition to his regular school work E, by the time he was 8 years old, had covered the following special work in language and mathematics, either with a tutor or with his mother:
Mathematics: Algebra as far as equations; geometry.
Latin: Partial knowledge of the four declensions (he has been taught by the direct, informal method, and reads easy Latin).
Greek: Worked out the alphabet for himself from an astronomical chart, between the ages of 5 and 6 years.
French: Equal to about two years in the ordinary school.
Spanish: Attended class with his mother--reads and understands.
Italian: Reading knowledge and simple conversation.
Portugese: Asked his mother to take this course at the Columbia Summer School because he could not be registered himself.
Astronomy: He has worked out all the constellations from MacCready, and displays a very great interest in this subject.
One evening this winter he noticed a new planet near the Twins. He said it was Saturn but his mother thought it was Mars. E went home, worked the position out from the chart and found it to be Saturn.
Miscellaneous: He has a great interest in nature, wherever found, and is already able to use Apgar intelligently.
His writing is not equal to his other accomplishments. He is very slow at it and for this reason dictates most of his "home work" to a stenographer.
History is his chief and absorbing interest among school subjects.
At the time E was first tested, at Teachers College, Columbia University, in November, 1916, the Stanford revision of the Binet-Simon measuring scale was used for the determination of the child's mental level.
_General intelligence_. The examiner [[L. S. H.]] began with the "ball-in-the-field" test. E responded at once with the superior solution, thus giving a preliminary cue to the quality of his mind, and the examiner proceeded immediately with the other tests at the 12-year level of intellect. E passed all the 12-year tests with facility and ease, giving responses of excellent quality. From the 12-year level the examiner then worked forward in all the higher levels through Superior Adult. This is, of course, a long examination, and in view of the actual age of the child it was deemed best to give the tests at two separate sittings, when it was seen that he would cover the whole upper range of the scale. The examination was therefore accomplished in two sittings of about fifty minutes each. The final record of E shows that he measures on the scale as follows:
