Theories of Transubstantial Transfiguration is a book in Quidditch Through the Ages.
Albus Dumbledore borrowed a copy from the Hogwarts library. While he was reading it, he absentmindedly doodled on a page. Irma Pince, the librarian, had jinxed the book just in case anyone damaged it. Dumbledore was suddenly attacked by the book which beat him fiercely around the head.[1]
