rted to the Royal Society in 1748 the history of a
child which was born with a tumor near the anus larger than the whole
body of the child; this tumor contained rudiments of an embryo. Young
speaks of a fetus which lay encysted between the laminae of the
transverse mesocolon, and Highmore published a report of a fetus in a
cyst communicating with the duodenum. Dupuytren gives an example in a
boy of thirteen, in whom was found a fetus. Gaetano-Nocito, cited by
Philipeaux, has the history of a taken with a great pain in the right
hypochondrium, and from which issued subsequently fetal bones and a
mass of macerated embryo. His mother had had several double
pregnancies, and from the length of the respective tibiae one of the
fetuses seemed to be of two months' and the other of three months'
intrauterine life. The man died five years after the abscess had burst
spontaneously.

Brodie speaks of a case in which fetal remains were taken from the
abdomen of a girl of two and one-half years. Gaither describes a child
of two years and nine months, supposed to be affected with ascites, who
died three hours after the physician's arrival. In its abdomen was
found a fetus weighing almost two pounds and connected to the child by
a cord resembling an umbilical cord. This child was healthy for about
nine months, and had a precocious longing for ardent spirits, and drank
freely an hour before its death.

Blundell says that he knew "a boy who was literally and without evasion
with child, for the fetus was contained in a sac communicating with the
abdomen and was connected to the side of the cyst by a short umbilical
cord; nor did the fetus make its appearance until the boy was eight or
ten years old, when after much enlargement of pregnancy and subsequent
flooding the boy died." The fetus, removed after death, on the whole
not very imperfectly formed, was of the size of about six or seven
months' gestation. Bury cites an account of a child that had a second
imperfectly developed fetus in its face and scalp. There was a boy by
the name of Bissieu who from the earliest age had a pain in one of his
left ribs; this rib was larger than the rest and seemed to have a tumor
under it. He died of phthisis at fourteen, and after death there was
found in a pocket lying against the transverse colon and communicating
with it all the evidences of a fetus.

500 students and many ph
