When reverting to Table V we see that more than half the 
number of boys and rather more than */, of that of the girls of 8 
years are slow Workers. Among the boys of 8 and 9 years there 
are respectively 6 and 14°/, quick workers; among the girls of the 
same age there are none. Since among the girls of 10 years there 
is as large a percentage of quick workers as among the boys of 8, 
the latter have the start of the former by two years. Later on this 
advantage lessens: then the boys between 9 and 10 years are on 
a level with the girls of 11; boys between 10 and 11 years on a 
level with girls of 12. 
Conversely, the percentage of slow workers among the girls is 
invariably greater than that of the boys of the same age. In course 
of time it also decreases far less rapidly among the girls. So also 
here the boys are in advance of the girls. Among the boys of 9
