Long Retention of Extrauterine Pregnancy .-- The time of the retention of an extrauterine gestation is sometimes remarkable, and it is no uncommon occurrence for several pregnancies to successfully ensue during such retention.

The Ephemerides contains examples of extrauterine pregnancy remaining in the abdomen forty-six years; Hannaeus mentioned an instance remaining ten years, the mother being pregnant in the meantime; Primperosius speaks of a similar instance; de Blegny, one of twenty-five years in the abdomen; Birch, a case of eighteen years in the abdomen, the woman bearing in the meantime; Bayle, one of twenty-six years, and the Ephemerides, another.

In a woman of forty-six, the labor pains intervened without expulsion of the fetus.

Impregnation ensued twice afterward, each followed by the birth of a living child.
