Besides maceration effects, many of the villi show marked changes, undoubtedly hydatiform in character. In this case it is possible that we are dealing not so much with absorption as with dissolution of the embryo, for the digestion products of embryo, yolk sac and amnion, instead of having been wholly absorbed still may be contained in the fluid within the chorionic vesicle. Before briefly considering the evidence regarding absorption offered by tubal and ovarian specimens, I wish to refer to number 1843. This specimen, which was donated to Stanford Uni-.
