The Crillon-quotation on page 62 is due to Mr. W. M. Salter (who employed it in a similar manner in the 'Index' for August 24, 1882), and the dream-metaphor on p. 174 is a reminiscence from some novel of George Sand's—I forget which—read by me thirty years ago.

Finally, the revision of the essays has consisted almost entirely in excisions. Probably less than a page and a half in all of new matter has been added.
