We are enabled to throw some fresh light upon the doings of the powers in whose high hands lay the prisoner’s life from certain correspondence, hitherto unpublished, relating to her case. These documents, here printed for the first time from the original MSS. in the British Museum and Public Record Office, will be found in the Appendix.
