The Uffenbach brothers are visiting Van den Bogard in Delft. Besides his large collection of naturalia he also had some good paintings. Uffenbach purchases from him a small portrait of Erasmus for 3 guilders and his brother a "perspective" of the Oude Kerk by Johannes Coesermans for 14 guilders. Uffenbach describes the gratitude festival that night, which ended with shooting and music from the carillon. The next morning they visit Leeuwenhoek with a recommendation by Van Arckel. They are received by his daughter, who tells them that her father had found many new things through his microscope but refuses to publish his findings because he is being mocked.
