The August letter in this folder discusses the injustice of the execution of Jean Calas because he was not a Catholic. Frederick complains about how Calas had no proof or evidence against him, and also did not have a witness. He writes how he thinks that the law should punish people in proportion to their faults, but that in the case of Calas, it didn't happen that way because the magistrates used their own judgment instead. The letters are signed with a large and elegant letter "F".
