J., who lent them, with his own notes on them, to Andrew Lang for use in his book, The Mystery of Mary Stuart (1900-1904).
It was argued by Andrew Lang that Wood was likely to show these letters to Lennox; and that as Lennox follows Moray's version of Mary's long and murderous letter, and does not follow Letter II., the murderous letter (a forgery) was then part of the dossier of Mary's accusers.
But Lang did not long remain an official.
In 1792 Lang again betook himself to a university, this time to Gottingen.
At intervals from 1793 to 1801 Lang was closely connected with the Prussian statesman Hardenberg, who employed him as his private secretary and archivist, and in 1 797 he was present with Hardenberg at the congress of Rastadt as secretary to the legation.
