First page of the Postscript, page 383, paragraph 1, sentence 4. "The experience was so much fun that I wanteßd to try something again..."
"Latin small letter sharp s" (eszett) is used instead of an apostrophe. I'm not sure if this is a printing error exclusive to this specific copy, or if it's included in other books.
I left the little publishing info page, in case anyone wanted to check. This is a library copy.
