Table i c. 

 Higher schools. Boys. 



Only schools for normal children. The school for feeble-minded children omitted. 

 7 years and 2 months. A special calculation of this youngest year class showed, 

 that the average age for those who stood nearest to 7.0 was 7.1 1. It was really 

 anticipated that there so far out in the school year would be a deficit of the 6% 

 to 7 group against 7 to 7%. 



The value of 7.1 1 was first marked in its place on the curve, which then was 

 drawn up towards the left after its most natural continuation to 7.0.
