Between experiments, Aylmer tells Georgiana about alchemy. He believes that he could turn base metal into gold and create a potion that would grant eternal life if he wanted to, even though he says he knows that doing so would be wrong. He disappears for hours and then shows her his cabinet of wonders. One such wonder is a vial that holds a powerful perfume. Another is a poison that, depending on the dose, would allow Aylmer to kill someone instantly or after a long period of time. Georgiana is appalled, but Aylmer says the poison is more good than bad. He shows her another potion that can wipe away freckles, but he says her birthmark needs a much deeper cure.
