The relation of the facial form with the head form is shown in 

 the next table. The average lowest facial indices, in other words 

 the least oblong faces, correspond to a somewhat higher cephalic 

 index, that is to somewhat more rounded heads, than the average of 

 the highest indices or most oblong faces ; and the same result appears 

 when the lowest and highest cephalic indices are taken as the base 

 of the comparison. The correspondence of the facial and head form 

 is seen to be quite limited, which is rather surprising, for it was 

 shown before that there exists a considerable direct correlation be- 

 tween, on one side, the facial height and the head length, and on the 

 other between the facial and head breadth. And the weakness of 

 reciprocal relations between the two indices is made still more evi- 

 dent by the many individual exceptions to their correspondence. A 

 partial explanation at least of these facts appears to be possible by 

 the assumption, justifiable by the conditions shown by the individual 

 measurements, that the face dimensions vary to some extent inde- 

 pendently of those of the head, and that this form of variation dis- 

 turbs or obscures more or less the otherwise well established cor- 

 relation of the parts.
