Since Willoughby's time several cases of similar interest have been noticed, one in a woman of forty, who had been married sixteen years, and who had had several pregnancies in her early married life and a recent abortion.

Her last pregnancy lasted about twenty-eight or twenty-nine weeks, and terminated, after a short labor, by the expulsion of the ovum entire.

The membranes had not been ruptured, and still enclosed the fetus and the liquor amnii.

On breaking them, the fetus was seen floating on the waters, alive, and, though very diminutive, was perfectly formed.

It continued to live, and a day afterward took the breast and began to cry feebly.
