A congratulatory letter from Lord Kinnoull to the Duke of Atholl dated 9 March 1765, immediately following the conclusion of the Isle of Man Revestment agreement with the British Government. Kinnoull affirms that the Duke acted wisely in accepting the compensation offered, despite concerns about its adequacy. The letter also praises the parliamentary advocate Mr Cooper's performance at the Bar of the House of Commons. This is a key contemporaneous source confirming the Duke's acceptance of terms and the successful conclusion of negotiations.
