“Let’s try again. Potter, where would you look if I told you to find me a bezoar?”
Hermione stretched her hand as high into the air as it would go without her leaving her seat, but Harry didn’t have the faintest idea what a bezoar was. He tried not to look at Malfoy, Crabbe, and Goyle, who were shaking with laughter.
“I don’t know, sir.”
“Thought you wouldn’t open a book before coming, eh, Potter?” Harry forced himself to keep looking straight into those cold eyes. He had looked through his books at the Dursleys’, but did Snape expect him to remember everything in One Thousand Magical Herbs and Fungi?
Snape was still ignoring Hermione’s quivering hand.
“What is the difference, Potter, between monkshood and wolfsbane?”
At this, Hermione stood up, her hand stretching toward the dungeon ceiling.
“I don’t know,” said Harry quietly. “I think Hermione does, though, why don’t you try her?”
A few people laughed; Harry caught Seamus’s eye, and Seamus winked. Snape, however, was not pleased.
“Sit down,” he snapped at Hermione. “For your information, Potter, asphodel and wormwood make a sleeping potion so powerful it is known as the Draught of Living Death. A bezoar is a stone taken from the stomach of a goat and it will save you from most poisons. As for monkshood and wolfsbane, they are the same plant, which also goes by the name of aconite. Well? Why aren’t you all copying that down?”
There was a sudden rummaging for quills and parchment. Over the noise, Snape said, “And a point will be taken from Gryffindor House for your cheek, Potter.”
Things didn’t improve for the Gryffindors as the Potions lesson continued. Snape put them all into pairs and set them to mixing up a simple potion to cure boils. He swept around in his long black cloak, watching them weigh dried nettles and crush snake fangs, criticizing almost everyone except Malfoy, whom he seemed to like. He was just telling everyone to look at the perfect way Malfoy had stewed his horned slugs when clouds of acid green smoke and a loud hissing filled the dungeon. Neville had somehow managed to melt Seamus’s cauldron into a twisted blob, and their potion was seeping across the stone floor, burning holes in people’s shoes. Within seconds, the whole class was standing on their stools while Neville, who had been drenched in the potion when the cauldron collapsed, moaned in pain as angry red boils sprang up all over his arms and legs.
“Idiot boy!” snarled Snape, clearing the spilled potion away with one wave of his wand. “I suppose you added the porcupine quills before taking the cauldron off the fire?”
