In 1763 he published a Dissertation on James Macpherson's Ossian, and from 1777 and onwards he published his (at the time) wildly popular 4 volume Sermons, which was praised even by Dr. Johnson.
"Learned and ingenious", according to Boswell.1
Boswell and Blair visited Thomas Sheridan together in London on April 6, 1763. On April 9, 1763, they went to Covent Garden with William Nairne. Boswell and Blair moved in the same circles in Edinburgh society from the time Boswell returned to that city in 1766 and often met for social and cultural events.
On [Abebooks] you can find both Lectures on Rhetoric, his Sermons and even original engraved portraits of Blair as well as Robert Morell Scmitz' 1948 biography Hugh Blair.
