Note 86 — Chapter X
Reading edition
Owen quotes in the Anatomy of Vertebrates, Vol. III. p. 721, a description from Rengger of the development of Didelphis azaræ, which would seem to imply that a vascular adhesion arises between the uterine walls and the subzonal membrane, but the description is too vague to be of any value in determining the nature of the fœtal membranes.
