Ratings for traits of character and for physique gave this child a score much above average in both respects. She weighed 11 pounds and 15 ounces at birth, and at the age of 8 years 2 months corresponded to the standard for 9 years 6 months in weight and for 10 years 6 months in stature. Her hand grip at this time was equal to that of the average 10-year-old. She began to walk at 7 months of age, which is the earliest age of walking recorded for any of the children so far studied, including those who are the special subjects of this monograph. At 19 months she talked clearly and knew the alphabet; and at the age of 4 years 6 months she was discovered reading _Heidi_, a book of about fourth-grade degree of difficulty. Her parents did not know that she could read, and they have no idea when or how she learned. By her eighth birthday Beatrice had read approximately seven hundred books, many of them twice. At that age it was one of her favorite pastimes to write stories or poems and to illustrate them with original drawings. Her health was said by her parents to be excellent. The measurements given show her to be large and strong for her age. Beatrice was not entered at school until she was 11 years old, but studied at home under her mother's guidance. There was little formal instruction--as a rule there was arithmetic, from ten to twenty minutes daily. At 11 years of age Beatrice entered the ninth grade of a private school for girls, which she attended for two years. She entered the university when she was 14 years 8 months old, and graduated at 17. In college Beatrice earned A and B grades in English and languages and C's in science. She fell barely short of Phi Beta Kappa Election. Throughout her life she has had few playmates and few intimate friends. Her desire is for a literary career. _Root's case, VIII A_. In 1921 Root (18) described a boy who at the age of 8 years 0 months scored at a Mental Age of 16 years 0 months, with an IQ (S-B) of 200. Other tests agreed in placing this boy near an average adult level in processes of thought. The stature of the child at this time was 4 feet, and the weight 59 pounds. The ancestry in the case is predominantly English. Father and mother both graduated from high school. The father was a railroad engineer. Two maternal aunts held prominent places in the public schools. The family had "all comforts but few luxuries." "The aunt who has guided the [[boy's]] education seems a rare combination; her educational ideas are a happy union of radical, common sense, and practical factors." "Nervous temperament" is judged by Root to be characteristic of the family on the mother's side.
