Vaginal examination revealed a dilatation of the os uteri of at least one inch and a fetal head pressing out; subsequently a living fetus of about six months of age was delivered.

Severe hemorrhage complicated the case, but was controlled, and convalescence speedily ensued.

Huse cites an instance of a mother bearing a boy on November 4, 1834, and a girl on August 3, 1835.

At birth the boy looked premature, about seven months old, which being the case, the girl must have been either a superfetation or a seven months' child also.

Van Bibber of Baltimore says he met a young lady who was born five months after her sister, and who was still living.
The most curious and convincing examples of superfetation are those in which children of different colors, either twins or near the same age, are born to the same woman,--similar to that exemplified in the case of the mare who was covered first by a stallion and a quarter of an hour later by an ass, and gave birth at one parturition to a horse and a mule.
