In Germany, in the seventeenth century, there lived a woman who on three different occasions is said to have vomited a fetus.

The last miscarriage in this manner was of eight months' growth and was accompanied by its placenta.

The older observers thought this woman must have had two orifices to her womb, one of which had some connection with the stomach, as they had records of the dissection of a female in whom was found a conformation similar to this.
Discharge of the fetal bones or even the whole of an extrauterine fetus by the rectum is not uncommon.

There are two early cases mentioned in which the bones of a fetus were discharged at stool, causing intense pain.

Armstrong describes an anomalous case of pregnancy in a syphilitic patient who discharged fetal bones by the rectum.
