Menstruation; Miscarriage

This class of human Ova throw no inconsiderable light on the
  progress of fœtal intro-uterine life. They prove that the embryo,
  called into existence by the mysterious act of fecondation (the only
  point that _is_ mysterious about the process of generation according
  to Cuvier) may, and will, and does live independently of the
  mother,—with a life wholly its own, and that it derives from its
  parent growth only, or accretion of substance, as I stated in my
  preliminary observations. The museum of the Royal College of
  Surgeons supplies a most striking illustration, and I may add,
  corroboration of this opinion.

  No. 3448 is a single spherical denudated diaphanous Ovum about six
  inches in diameter, without the slightest appearance of any
  placenta, filiform or cotyledonous vessels, or other of the
  nutritive involucra or membranes. The secreting or amnionic
  membrane, is capable of containing more than six ounces of fluid;
  yet the embryo is not larger than an embryo at one month. When this
  specimen was sent by Mr. Lugar, of Richmond, to the College, Mr.
  Clift found it attached to a PLACENTAL OVUM, containing a perfect
  fœtus of the proper size at four months and a half, with an
  umbilical cord nine inches long. The attachment of the two or _twin_
  Ova, was by a spot not larger than a shilling, which is still
  visible on the smaller or diaphanous Ovum, and was of a bright red
  colour at the time of separating the two Ova for the purpose of
  making a distinct preparation of the more complete Ovum, marked in
  the museum 3448 A.

  It appears that the twin Ova were ejected together five months after
  menstruation.

  That the embryo in the smaller Ovum _lived_ is proved by its size as
  well as by the secreting involucrum having enlarged with fluid to
  the capacity afore stated. But it did not grow, because
  _unconnected_ with the mother; while the twin fœtus properly
  encircled by the placental envelopes, which placed it in immediate
  communication with its parent, lived as well as acquired growth.
