"The Uffenbach brothers are visiting the Pesthuis in Leiden. Uffenbach mentions a relief depicting an allegory of the pest above the door. That afternoon they visit professor Salomon van Til for two reasons: to talk with him, but also in his function as former secretary of the university to get a pass for shipping their cases. Uffenbach notes down a rumour about how he makes money from students. The next day, the brothers visit the medicinal garden. Uffenbach notes down several trees and plants he observes."
