_Rusk's case, from Scotland_. In 1917 Rusk (19) published an account of a Scottish boy whose IQ, calculated from Rusk's detailed record, was 166 on first test and about 200 on second test given two and a half years later, the Binet-Simon tests of 1911 being used. This child was the son of a widow in Dundee, who lived and supported her two sons by letting rooms to lodgers. The young brother of this boy was not judged to be remarkably intelligent, but no test was given to substantiate this impression. Details of family history are not recorded.
The boy was brought to attention at the age of 5 years by his teachers, who noted particularly his aptitude for mathematics. The mother was unaware of her son's extraordinary intelligence, but she had noticed that he spent a considerable amount of time on the floor, counting. He would count such objects as cigarette coupons begged from lodgers. Also the mother observed that he "had learned before going to school, or being taught to read, to recognize certain words."
CHILDREN WHO TEST ABOVE 180 IQ BY STANFORD-BINET TESTS
_Beatrice_. Terman and Fenton (25) first described Beatrice in 1921 under her own name. In 1930 Terman (27) again described this child, under the name of Beatrice (evidently being then convinced that pseudonyms are to be preferred in designating children studied), adding data about development.
The child's four grandparents were respectively of Swedish, German-French, English, and Scottish descent. "The mother is a woman of more than average intelligence, and of considerable musical ability. The father's line of ancestry includes several notables, among them a Lord Mayor of London. The father is a physician, and the author of the _Ford Stitch_, favorably mentioned in standard texts on surgery. Betty [Beatrice] has no sisters or brothers."
Beatrice was born in San Francisco, January 21, 1912, and was first tested six weeks before her eighth birthday, by Stanford-Binet, yielding then a mental age of 14 years 10 months and an IQ of 188. Her speaking vocabulary was at that time 13,000 words. A variety of mental tests gave nearly the same composite result as that achieved by Stanford-Binet. At the time of testing, the child had never attended school but had been given a little private instruction at home. Her scores on standard tests of scholastic knowledge ranged, nevertheless, from fifth-grade norms (in the four fundamental processes in arithmetic) to second year of college (in tests of poetic appreciation). Her median score in eight scholastic tests was about eighth grade (where the median birthday age of pupils is about 14 years, and where pupils have been in school on an average of eight years).
