According to Bateman, and also Rueff, in the year 1552 there were born, not far from Oxford, female twins, who, from the description given, were doubtless of the ischiopagus type.

They seldom wept, and one was of a cheerful disposition, while the other was heavy and drowsy, sleeping continually.

They only lived a short time, one expiring a day before the other.

Licetus speaks of Mrs.
John Waterman, a resident of Fishertown, near Salisbury, England, who gave birth to a double female monster on October 26, 1664, which evidently from the description was joined by the ischii.

It did not nurse, but took food by both the mouths; all its actions were done in concert; it was possessed of one set of genitourinary organs; it only lived a short while.
