In August 1698, Leeuwenhoek wrote to Magliabechi:

The Reverend Papenbroek personally handed me Your very kind letter, Most Illustrious Sir, at the time when recently, during my stay at Antwerp, I was given an opportunity to enjoy his company and his most learned conversations. From this letter I see that You do not by any means advise me to reimburse the Man in question, who lives at Brussels, in any way for the expenses he says he has incurred in getting the Book (with which you recently saw fit to make me happy).
