GB here Mag borrowed on page 25, but I don't know the pagenumber of the source, and there is more on the previous page not shown. - The current edition at the time would have been the 5th 2003, or 5th updated 2005. Substantial parts of the 7th ed are available here. There one finds the passage on page 334 in "Chapter 14 - Immunologic Tolerance and Autoimmunity".
