I believe the 6th and 7th diagrams (reading left to right, top to bottom)
in the Bézier vertices examples are incorrect.

On the 6th diagram the control line from (V1, C1) to C2 should not be
present, there should be a line from (C3, V2) to C2 instead. Also the line
from (C3, V2) to C4 should be replaced with a line from V3 to C4.

On the 7th diagram the line from (C3, V2) to C4 should not be present,
there should be a line from (C1, V1, V3) to C4 instead.

I agree. We'll get this fixed for the next printing.
