Note 47 — PART I. MENSTRUATION.

It is very unusual, in this climate, for a girl to become a mother until she be seventeen or eighteen years of age. A case has just occurred, however (1864), where a girl became a mother before she reached her fourteenth year. In his last report to the Registrar-General, the registrar for Park district, Sheffield, says: “I have registered the birth of a child in my district this quarter, the age of the mother being only thirteen years and ten months. She was employed in a cotton mill in the neighborhood of Manchester.”
