Note H — The Alcove. (continued 2)

During the youth of the printer of this book, a curious mistake occurred: a splendid folio work was going on for Dr. Bonnell Thornton; in a certain page, as printers technically say, a space stood up; the Dr. (not understanding printers' marks) wrote on a head page "take out horizontal line at p. so and so"—the compositor inserted these words as a displayed line in the head-page whereon they were written—the reader passed it in the revise—and it was so worked off! Being eventually detected—the leaf was of course cancelled.
