- The closing remarks made at the end of a book, story, performance, etc.“And I well remember that when I visited Elizabeth in her German Garden, during the early years of the April, May, and June babies, those charming young persons were in the habit of writing not only introductions but "outroductions" to their own manuscript novels.
