Su`per*fe*ta"tion (?), n. [Cf. F. superfétation.] (Physiol.)

The formation of a fetus at the result of an impregnation occurring after another impregnation but before the birth of the offspring produced by it. This is possible only when there is a double uterus, or where menstruation persists up to the time of the second impregnation.

In then became a superfetation upon, and not an ingredient in, the national character.
Coleridge.
