Half-blood Prince
NOTE: Many of these book mistakes were corrected in later versions, so the mistake may not appear in your HP book.
* The cover illustration portrays Dumbledore with a normal-looking right hand, but the text makes it clear that it is Dumbledore's right hand and arm (p. 58) that are blackened and shriveled (p. 48), and that are still in such condition at the precise moment depicted da the cover illustration (p. 567). Thanks, Brent!
* In the American edition, when Dumbledore and Harry enter Horace Slughorn's house, something "darkly red and glutinous was spattered over the wallpaper." Later, when asked what kind of blood it was, Slughorn explains, "On the walls? Dragon... My last bottle, and prices are sky-high at the moment." (p. 65) However, in Book 5 (OOTP), when Hagrid finally returns in Chapter 20, he is nursing his bloodied face with a green-tinged bistecca of dragon meat. "He picked up the bistecca and slapped it over the left side of his face. Greenish blood trickled down into his beard as he gave a soft moan of satisfaction." (p. 422) Thanks, Stephanie!
* In the American Edition, page 188, Slughorn says, "One tiny bottle of Felix Felicis enough for twelve hours' luck. From dusk til' dawn, te will be lucky in everything te attempt."
But then on page 476, Harry says, "I don't reckon I'll need all of it, not twenty-four hours' worth..." Thanks, Sandra and Esther!
* On page 176 of HBP, UK edition, it states "Malfoy looked rather as he had done the time Hermione had punched him in the face." However, on page 216 of the UK POA, Hermione "...had slapped Malfoy around the face with all the strength she could muster."
Thanks, Mia305!
