The external labia and the vulva in all its parts were well formed, and the mons veneris was covered with a full growth of hair.

Sir Astley Cooper, Mandelshof, the Ephemerides, Rause, Geoffroy-Saint-Hilaire, and several others a report instances of menstruation occurring at three years of age.

Le Beau describes an infant prodigy who was born with the mammae well formed and as much hair on the mons veneris as a girl of thirteen or fourteen.

She menstruated at three and continued to do so regularly, the flow lasting four days and being copious.

At the age of four years and five months she was 42 1/2 inches tall; her features were regular, the complexion rosy, the hair chestnut, the eyes blue-gray, her mamma the size of a large orange, and indications that she would be able to bear children at the age of eight.
