years of the century began to be largely entrusted with the conduct of Hanoverian diplomacy in its relations to both England and Holland, he seems generally to have been on excellent terms. But from 1705 onwards, when after the reunion of Celle and Hanover Bernstorff became the leading minister of the Elector George Lewis, and Bernstorff's right hand man, the Huguenot Robethon, was charged by him with reports on the progress of the Succession question, Leibniz's communications with the Electress Dowager on the subject become essentially those of a private correspondent.
