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.
