Dantiscus sends the chapter copies of the letter to the duke [Albrecht von Hohenzollern] and his reply to it. In light of this exchange, he sees the need to revise the previously prepared draft of a joint letter from himself and the chapter to the duke. He recommends that the provost [Paweł Płotowski] and Doctor Nicolaus [Copernicus] should come to him the following day in order to discuss these revisions.
