Correlation of General Intelligence and Place in Form for constant Age and 
constant Form : — 
(a) With the higher values of r 13 and r^... p 12 = — "582 + - 029. 
(b) „ lower „ „ ... p 12 = - -631 + -026. 
This correlation is lower than in the first investigation for General Intelligence 
and Place in Form and, as was mentioned before, the result is most likely due, at 
least in part, to the fact that one-third of the boys had been under observation 
for a much shorter time than in the first case. 
(vi) General Conclusions. It will be seen that although the individual 
correlations for the two series differ considerably, the partial correlations of 
General Intelligence and Place in Form for constant Age and constant Form are 
not widely separated. We see at the same time, however, that General Intelli- 
gence is more closely related to Examination Place than to Place in Form 
('87 against - 81, taking the higher value in each case ; or "83 against 75, taking the 
lower values). These values agree well with those found by Miss H. G. Jones in 
her series from the Aberdeen Schools (see Biometrika, Vol. VII. p. 547). Place in 
Form depends largely on boldness and presence of mind in classwork ; a shy boy 
* Form Vc did not exist at the time for which the first Keport was made.
