In some versions of the book there are some errors on pages 528-9. These can be seen in the version which is linked to in the board called "Useful Links".
Here is a copy of the text from my version of the book, which is the most up-to-date version:
Bottom of page 528- top of page 529.
"Put differently this says that the circulation along a path between two points in the flow is dependent on the choice of that path. The circulation $\Phi(z)$ along a path from a fixed point to a variable point $z$ is a multifunction of $z$: if the difference of two paths is a loop winding round the obstacle $n$ times, the difference of the two values of $\Phi(z)$ will be $nS$."
