 children will, in most cases, all have high artistic ability 

 (Fig. 23). 



The data for this generalization are sparse. Four matings of this sort 

 furnished 13 children of whom 10 had a high grade, 1 is recorded as medium 

 and two as poor; but both of the latter occur in one record that gives in- 

 ternal evidence that the question was not clearly understood.
