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
