standardization of his language-completion tests, and of Woody in his standardization of his arithmetic tests. In this section the final results, merely, will be presented.

Graph I. is the curve indicating the scores to be expected at the various ages from 3 years to 19 years. This curve has been smoothed but slightly within the range of ages below ten, though rather considerably from fifteen to nineteen. This was necessarily the result of a deficiency in the number of cases at the higher ages. The median score at each age is represented by a circlet with a dot enclosed.
