[Footnote C: One method of advertisement which I observed in Chicago has
not yet, so far as I know, been introduced into England. One of the
windows of a vast dry-goods store on State Street was fitted up as a
dentists parlour; and when I passed a young lady was reclining in the
operating-chair and having her teeth stopped, to the no small
delectation of a little crowd which blocked the side-walk.]
