Menstruation; Miscarriage

In this specimen of an early miscarriage, the Ovulum exhibits the
      filiform vessels as in No. 1; but one half of its circumference is
      denuded of them, and the diaphanous involucra are distinctly
      visible in that part. They are represented flaccid owing to the
      escape of a part of the liquor amnii. In size the embryo (which
      required to be viewed in a very strong light) resembled that of
      No. 6.

            (Three weeks after menstruation.)

      A mossy Ovulum, shewing the inner or secreting membrane, within
      which I could not discover any embryo at the time of the
      miscarriage occurring. On searching among the coagula consequent
      on a very extensive hemorrhage, the Ovulum was found flat, and
      appeared like a confused mass. The liquor amnii had escaped, and
      probably the embryo along with it. The artist has most skilfully
      delineated the peculiar turns of the involucra where they have
      been divided so as to display those marked inflexions which are
      still more distinctly seen in No. 4.


Fig. 4. Ovulum semi-lanuginosum.

            (Four weeks after menstruation.)

      I look upon this as one of the most perfect specimens of
      mono-embryoferous Ovula at four weeks, I have seen; exhibiting as
      it does, not only the mossy or _nutritive_, but also the inner,
      amnionic, or _secreting_ involucrum, with its peculiar inflected
      turn, forming a _sacculum_ within which is lodged the embryo. The
      nutritive involucrum is separated from the middle membrane by the
      _allantoid_ cavity, and the middle membrane itself stands aloof
      from the amnion, owing to the _vesicula umbilicalis_. The
      existence of these various elementary parts of the human Ovum in
      the present specimen, shews its early development, and serves to
      fix its age, which I consider to be of about three weeks and a
      half.

      As gestation advances, some of those elements are obliterated, and
      others confounded together.


                                REMARKS.


  I imagine that these Ovula pass away from the womb almost
  immediately after they have entered it, owing to a tardy or
  deficient formation of that peculiar lining which the uterine cavity
  begins to weave for itself from the first moment of a successful
  copulation, and to some part of which the Ovula are destined to
  adhere.
