Transcriber’s Notes
Illustrations which were line-drawings had page numbers which were not printed; illustrations which were more complex had no numbers and had facing blank pages. This accounts for the oddities in page numbering.
Obvious typographical errors have been corrected silently. Less obvious ones which were changed are:
page [9], latter was replaced by letter
page [18], drawing-toom was replaced by drawing-room
page [153], Twen- at end of a line and not finished on next line was replaced by Twentieth
