Note 156 — BOSWELLIANA.

The celebrated George, tenth Earl Marischal, whom Boswell had the honour of accompanying through Germany and Switzerland in 1763. Born about 1693, Lord Marischal held a high command in the army of Queen Anne, and on her death signed the proclamation of George I. Deprived of office by the Duke of Argyll, he joined the Earl of Mar in the insurrection of 1715, and at the battle of Sheriffmuir commanded two squadrons of cavalry. In 1719 he made a second attempt on behalf of the Chevalier. In the rising of 1715 he took no part. Having by a residence in Prussia gained the favour of Frederick the Great, he became Prussian ambassador at the courts of France and Spain. In 1759 he revealed to Mr. Pitt, afterwards Earl of Chatham, the family compact of the house of Bourbon; he was, consequently, invited to the court of George II., and his attainder was reversed. On possessing himself of his forfeited estates he purposed to reside in Scotland, but on the urgent entreaty of the Prussian monarch he returned to Berlin. He died, unmarried, at Potsdam, on the 28th of May, 1778.
