The following is an excerpt from Chapter Thirteen of Harry Potter and the Prisoner of Azkaban:

Plunging a hand down the neck of his robes, he whipped out his wand and roared, “Expecto patronum!”

Something silver-white, something enormous, erupted from the end of his wand. He knew it had shot directly at the dementors but didn’t pause to watch; his mind still miraculously clear, he looked ahead — he was nearly there. He stretched out the hand still grasping his wand and just managed to close his fingers over the small, struggling Snitch.

…

“That’s my boy!” Wood kept yelling. Alicia, Angelina, and Katie had all kissed Harry; Fred had him in a grip so tight Harry felt as though his head would come off.

…

“Yes!” Ron yelled, yanking Harry’s arm into the air. “Yes! Yes!”

“Well done, Harry!” said Percy, looking delighted. “Ten Galleons to me! Must find Penelope, excuse me–”

“Good for you, Harry!” roared Seamus Finnigan.

“Ruddy brilliant!” boomed Hagrid over the heads of the milling Gryffindors.

“That was quite some Patronus,” said a voice in Harry’s ear.

Harry turned around to see Professor Lupin, who looked both shaken and pleased.
