"Uffenbach completes noting down the names of the people on the 20 portraits in the library of the University of Franeker. One of these portraits does not include the name and remains unidentified. Uffenbach comments on the portraits not being original. The librarian informs them about the negotations between the States of Friesland and the heirs of Oiselius about purchasing his book collection. That afternoon the Uffenbach brothers visit Gürtlerus, who has a small but good collection of mainly history books."
