In 1792 the eleventh Earl of Buchan published a volume of Essays on the Life and Writings of Fletcher of Saltoun and the Poet Thomson. It contains our only biography of Fletcher; but, though founded on original sources of information, it is frequently inaccurate, and must, therefore, be used with great caution. The author of the article on Fletcher in the third edition of the Encyclopædia Britannica (1797) mentions that the tenth Earl Marischal, when Governor of Neuchâtel, suggested to Rousseau that he should write the life of Fletcher. Rousseau was furnished withmss. for this purpose; but nothing came of it, and most of the materials on which that work was to have been founded seem to have been lost.
