She recovered and was doing her work. There was no possibility
that this was a case of retained secundines.
Anomalies of the Umbilical Cord.--Absence of the membranes has
its counterpart in the deficiency of the umbilical cord, so
frequently noticed in old reports. The Ephemerides, Osiander,
Stark's Archives, Thiebault, van der Wiel, Chatton, and Schurig
all speak of it, and it has been noticed since. Danthez speaks of
the development of a fetus in spite of the absence of an
umbilical cord. Stute reports an observation of total absence of
the umbilical cord, with placental insertion near the cervix of
the uterus.
There is mentioned a bifid funis. The Ephemerides and van der
Wiel speak of a duplex funis. Nolde reports a cord 38 inches
long; and Werner cites the instance of a funis 51 inches long.
There are modern instances in which the funis has been bifid or
duplex, and there is also a case reported in which there were two
cords in a twin pregnancy, each of them measuring five feet in
length. The Lancet gives the account of a most peculiar pregnancy
consisting of a placenta alone, the fetus wanting. What this
"placenta" was will always be a matter of conjecture.
Occasionally death of the fetus is caused by the formation of
knots in the cord, shutting off the fetal circulation; Gery,
Grieve, Mastin, Passot, Piogey, Woets, and others report
instances of this nature.
