Chapter 12 paragraph 9: inserted paragraph start and opening quotes
before "You observe, in both these skulls" -- blockquotes cannot be
inside paragraphs in the layout scheme.

Chapter 12 paragraph 13: inserted closing quotes after "becoming a
judge." -- they appear to be missing, since the speech is not
continued in the next paragraph.

Chapter 13 paragraph 17: replaced "woful" with "woeful" in "by woful
experience" -- it appears to be a spelling error.

Chapter 13 ballad: replaced "feats" with "feasts" in "O rich are the
feats" -- it appears to be a spelling error.

Chapter 14 paragraph 3: replaced fullstop with questionmark after
"Llewelyn Ap-Yorwerth" -- the sentence is a question.

Chapter 14 paragraph 5: inserted comma after "said the lady" -- one
would be expected here.

Chapter 14 paragraph 27: capitalised "Squire" in ""Your daughter,"
said squire Headlong." -- all other instances of "Squire Headlong" are
capitalised.
