 differentiated bv the vocabulary scale. 



to the records of the understanding of sentence scores. Table 

 2 (p. 12) gives a class of 25 in which 12 children made Set C or 

 8 ; 6, Set B or 6 ; 6, Set A or 4 ; and 1 who fell below the lowest mark. 

 When we recall that the grade-interval between grades 4 and 5 is 

 1 or one-half the distance between Set A and Set B, and that the 

 difference between the best dozen members of this class and the 

 poorest half dozen is four times this inter-grade interval, the 

 case remains about what it was under the visual vocabulary 

 test. Nor is it improved by a study of Figure VIII where the 

 distribution of all the grades of one city is shown in parallel figures. 



In Figure IX there are shown the results for the grades of 

 one citv.
