Note 226 — Chapter XI
Reading edition
Menstruation has been known to commence in England at the age of eleven, generally in cases of well-nourished blondes, and in exceptional cases even earlier. It has been known to occur at nine years, but this was induced by a severe accident. This is unknown among the forest people. I made out the age of puberty to be not less than fifteen for girls, and eighteen for boys, among the tribes I was with.
