Haller observed a case of impregnation in a girl of nine, who had menstruated several years, and others who had become pregnant at nine, ten, and twelve years respectively.

Rowlett, whose case is mentioned by Harris, saw a child who had menstruated the first year and regularly thereafter, and gave birth to a child weighing 7 3/4 pounds when she was only ten years and thirteen days old.

At the time of delivery she measured 4 feet 7 inches in height and weighed 100 pounds.

Curtis, who is also quoted by Harris, relates the history of Elizabeth Drayton, who became pregnant before she was ten, and was delivered of a full-grown, living male child weighing 8 pounds.

She had menstruated once or twice before conception, was fairly healthy during gestation, and had a rather lingering but natural labor.
