Everyone makes mistakes; including me. The errata for each release of the book is below. A special PDF of page 361 (based on an error in Release 1.1) is in another file (1):

The following forms are provided for your convenience:
(1) Page 361 of Release 1.1 has a PDF rendering error making part of the page unreadable. The PDF provided here is what that page should have looked like.
(2) Release 1.2 was only ever made as a PDF. If you have a copy of that PDF, it is highly recommended that you download a copy of Release 1.3; Errata will no longer be maintained (i.e., updated) for Release 1.2.
