1 See the following equation: 

 Nasal breadth X 100 _ 

 Nasal length 



The nasal index is very similar in the two groups of the Academy, and it is practically iden- 

 tical in these and the more aged and cultured old Americans at large. In all the series it shows 

 high variability, ranging with the most variable determinations on the human body. And 

 while it showed unmistakable increase with age in the series of the old Americans at large when 

 young adults were contrasted with older, 38 in the members of the Academy it is very near the 

 same in those up to and over 60, those indicating that while both the length and the breadth of 

 the nose have augmented slightly during advanced years their relative values remained very 



similar.
