In Chapter Ten: 'The Rogue Bludger' the American version has a picture of Harry's LEFT arm having no bones while in the text (pg. 171) it says that Harry's right arm was broken- "...his right arm dangling useless at his side..." If you have the American version of the book, check out the picture at the beginning of chapter 10. It's a minor mistake, but I'm a perfectionist and I just wanted to let ya'll know.
