Hermione sat in Potions class, making her Potion like always. Potions lessons took place in one of the large dungeons. Thursday afternoon's lesson proceeded in the usual way. Twenty cauldrons stood steaming between the wooden desks, on which stood brass scales and jars of ingredients. Snape prowled through the fumes, making waspish remarks about the Gryffindors work while the Slytherins sniggered appreciatively. Hermione, like always, had a perfect potion, and the others had started taking down notes on what she did. Her first and second year books had notes scribbled in the margins on all her changes, and Hermione hoped to bring these to the editors.
