I make them under the impression that I may use them in my books, but I
never do unless I happen to remember them at the right time. When I
wrote “Ramblings in Cheapside” [in the _Universal Review_, reprinted in
_Essays on Life_, _Art and Science_] the preceding note about Public
Opinion would have come in admirably; it was in my pocket, in my little
black note-book, but I forgot all about it till I came to post my
pocket-book into my note-book.
