Q. Are you sure that he had the plates at the time you were writing for him?
A. The plates often lay on the table without any attempt at concealment, wrapped in a small linen table cloth, which I had given him to fold them in. I once felt of the plates, as they thus lay on the table, tracing their outline and shape. They seemed to be pliable like thick paper, and would rustle with a metallic sound when the edges were moved by the thumb, as one does sometimes thumb the edges of a book.
