Clips and images from this book are from the Google Books edition scanned from a volume from the Harvard College Library.  Their scanned copy publisher was New York: Harper Brothers, Publishers, Franklin Square,  1862.

The quality of the scan varies greatly with many errors of punctuation and character recognition.  I attempted to validate the clips using an edition from The Narrative Press, 2003.  Theirs is reportedly a scan of the first edition from Longman, Green, Longman and Roberts, London, 1861.  The Narrative Press edition suffers from a lack of proof reading.

I eventually found Fawn M. Brodie's edition from New York Alfred A Knopf, 1963.  This is my preferred edition for reading and a source of much material about Richard F. Burton.
