Fig. Unica. Ovum ovaricum fœtiferum patefactum.

The cavity formed in the substance of the ovarium by the progressive advancement of the fecundated ovum, is here laid open, in order to exhibit how distinctly and perfectly the fœtus had, up to the time of the death of the mother, found station, nourishment and growth without the assistance of the cavity of the uterus, or of those membranes which physiologists are wont to look upon as essential to the development of the child in utero.

A placental mass with distinct cotyledonous vessels, connects the child with the inner covering of the ovarian cyst. The secreting or transparent involucra are quite distinct. The cortex ovi is almost wholly absorbed, as it ought to be at such an advanced period. The fœtus is perfect.
