are such that a series of measurements in any people on the adults in 

 the prime of life and on those above 60 years of age will invariably 

 stand well apart. The nose grows with the face far into the adult life, 

 but with the advance of senility becomes often independently broad- 

 er ; finally in those of old age its height tends rather towards diminu- 

 tion. The nasal index in the aged is thus heightened and the change 

 is at times such that what formerly was a leptorhinic nose becomes 

 mesorhinic, while one originally mesorhinic may become platyrhinic. 



In the Kharga men, among whom but few were older than 55 

 years of age, the age element, though not completely eliminated, is 

 relatively unimportant and the series may be considered in its en- 

 tirety. 



The average height of the nose was found to be only moderate, 

 amounting to 4.87 cm., and it was much the same in each group of 

 50; it is also practically the same with the mode and the median. 

 The range of variation of the measurement is ordinary, extending 

 over 18 mm., or ±0.18 per unit of the average. Eighty- four per 

 cent of the cases are contained within the limits of 4.4 to 5.25 cm. 

 The range of distribution of the measurement is fairly regular 

 (fig. 11).
