Harry attends Potions class, struggles with the Draught of Peace

PAGES: 231-234

In Potions class, Professor Snape assigns the Draught of Peace potion, which requires precise attention to detail. While Hermione excels, Harry struggles and forgets an important ingredient, leading Snape to taunt him in front of the class. Snape vanishes Harry's potion, giving him a zero for the day's work, and assigns homework on the properties of moonstone. Harry feels especially angry at the unfairness of Snape's treatment.
