Chapter 11: paragraph 3: replaced "y" in "Vouley" with "z" -- it

appears to be a spelling error.

Chapter 12 paragraph 1: replaced "wolves" in "individual lion, tiger, wolves," with "wolf" -- it is a list of singulars.

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.
