Boswell presented Arbuthnot to Dr Johnson in Edinburgh on August 15, 1773, a few days before Johnson and Boswell set out on their tour of Scotland and the Hebrides. Boswell wrote of him, in Journal of a Tour to the Hebrides, that he was "a relation of the celebrated Dr. Arbuthnot, and a man of literature and taste. To him we were obliged for a previous recommendation which secured us a very agreeable reception at St. Andrews, and which Dr. Johnson in his Journey1 ascribes to "some invisible friend"."
- 1Ten years before Boswell published his account of their journey, Dr Johnson had written A Journey to the Western Isles of Scotland (1775).
