IV. A SECOND EXPERIMENT IN A BOYS' SCHOOL.This experiment was carried out with the whole of a Standard IV class, numbering 51, of an average age of 11 years, 1 month, on June 30, 1911.The school was the same as that in which the previous experiment was done, but the standard of mental proficiency and the age of the boys were different and they were taught by a different teacher.This class was also taught by a young man of capacity, but differing from the teacher of the preceding class somewhat in the greater evenness, though, perhaps, slighter intensity of his demands upon the mental energy of his pupils.i.
