It's noted that Measures 25-29 'separate men from boys' and that the 9:8 figure in Measures 35-36 should flow nicely. However, looking at the music below, there are no such measures. I.E. the 9:8 figure is shown to be Measures 20-21.

KnightLineSnare - thank you for catching this. It was actually an error made when the excerpt was extracted for use in the book, but the text was written to the full score. The first citing should actually say Measures 9-13, and the second one should (as you've already deduced) say Measures 20-21.
