The breadth of the nose in our series is seen to be even more variable than its length. In 

 the two groups of the academicians it is nearly the same. It is perceptibly higher in the academ- 

 icians of both groups than in the old Americans at large, which may be attributed in part to 

 the higher presenile stature of the members, in part to their older age. The effects of age on 

 the measurement are discernible even among the academicians themselves, but are more marked 

 in the Americans at large, who include a series of young adults. 



The distribution of the measurement is much alike in the two groups of the Academy, but 

 in the not old Americans there is perceptible a tendency, probably based on racial differences, 

 toward fewer of the narrower and more of the broader noses.
