As George III. had made choice of Baron von Lichtenstein as the medium through which all immediate communications to him on the subject of the queen his sister should pass, it was highly important to apprise the baron of this intention. Mr. Wraxall accordingly wrote to him on the same day by the post, expressing in very few words that, on account of some circumstances which had arisen, he would probably see Mr. Wraxall again in London early in the ensuing month. The writer added, that if, unfortunately, the baron should have quitted England before his return, he relied on his leaving accurate directions in writing how to proceed in the affair. Mr. Wraxall also wrote to Baron von Seckendorf, apprising him that he might be expected again in Celle in a few days. On March 20, Baron von Bülow delivered Mr. Wraxall the letter for the King of Great Britain. It was not signed by him or by any of the party, on account of the danger incurred by such a signature.

That they were so numerous and powerful a body, possessed of such means, and inspired by motives so strong, as to render their success almost infallible. That the consent of the King of Great Britain to the only request preferred by them would, indeed, accelerate, as his refusal might retard, the accomplishment of the projected enterprise, but that nothing could prevent its ultimate execution. That even a discovery of the design would not frustrate it; and that, if the executioner should strike off ten heads or twenty, a number sufficient would still survive to seat her on the throne. That the plan, when ripe, would be carried into execution in the following manner:--
