p.262. Note. Should this be a Tip?
p.263. Bad list in Example 1. 7)-8) should be 1)-2).
p.270-1. Big space below the note, which doesn't make much sense
without the illustration. I think the markup figure would fit in here
but if not, the note should be moved to after the figure.
p.271-2. Ugly gap. Could the figure be moved up to fill it?
