There is not any very great variation in the correlations be- 

 tween marks in academic subjects, such as the languages, 

 sciences and mathematics. The Pearson coefficients run be- 

 tween 40 per cent, and 60 per cent. The correlations of 

 drawing with academic subjects are low — lying as a rule 

 between o and 25 per cent. From a psychological standpoint, 

 the academic correlations are high. But it must be borne 

 in mind that many constant errors enter which would make 

 the correlations much higher than the essential relationships 

 would be. From an educational standpoint the correlations 

 are low. They show the futility of the belief in general bright- 

 ness for all things, and are one of the best arguments for the 

 elective system. James E. Lough,
