Several large spiders were scuttling over the ground on the other side of the glass, moving in an unnaturally straight line as though taking the shortest route to a prearranged meeting.

| 359 | Mr Malfoy almost knocked Harry over as he swept into the room. Dobby went scurrying in after him, crouching at the hem of his cloak, a look of abject terror on his face. ‘So!’ said Lucius Malfoy, his cold eyes fixed on Dumbledore. ‘You’ve come back. The governors suspended you, but you still saw fit to return to Hogwarts. | Mr. Malfoy almost knocked Harry over as he swept into the room. Dobby went scurrying in after him, crouching at the hem of his cloak, a look of abject terror on his face. The elf was carrying a stained rag with which he was attempting to finish cleaning Mr. Malfoy’s shoes. Apparently Mr. Malfoy had set out in a great hurry, for not only were his shoes half-polished, but his usually sleek hair was disheveled. Ignoring the elf bobbing apologetically around his ankles, he fixed his cold eyes upon Dumbledore. “So!” he said “You’ve come back. The governors suspended you, but you still saw fit to return to Hogwarts.” | 334 |
Other differences: The first Scholastic edition includes several sentences which are missing from the Bloomsbury text. Immediately after Ron says “We’re stuck, right? And we have to get to school, haven’t we? And even underage wizards are allowed to use magic if it’s a real emergency, section nineteen or something of the Restriction of Thingy …”, the following appears in the Scholastic edition only:
“But your mum and dad…” said Harry, pushing against the barrier again in the vain hope that it would give way. “How will they get home?”
“They don’t need the car!” said Ron impatiently. “They know how to Apparate! You know, just vanish and reappear at home. They only bother with Floo powder and the car because we’re all underage and we’re not allowed to Apparate yet…” (CS5)
This discrepancy endured even with the additions and corrections to the text in 2004.
