Four of the twenty-nine women have the "narrow" leptorhine nose with nasal index below 70; seven have platyrhine or the "broad" nose with index greater than 85; while seventeen have the "medium" or mesorhine nose with nasal index between 70 and 85. The broadest nose has an index of 97.56, and the narrowest an index of 58.53. The women reach the age of maturity well prepared for its responsibilities.
