The papers of Professor Hugh Blair consist principally of correspondence. The material includes: a letter probably to T. Cadell and to William Strahan and A. Constable, between 1778 and 1796 at Dc.2.76/10 which are copies from originals held by the Earl of Rosebery and 'in Edinburgh Public library'; letters to Miss Nancy Ord at Gen. 1730/1 Blair; and, another letter to Cadell and a letter to the Lord provost of Edinburgh at Dc.4.101 Blair. There are also lectures on rheoric and the belles lettres, in manuscript, and including Synopsis, taken down 1765, at Dc.10.6, and lectures, 1779, at Gen. 1990. There are further notes of lectures on rhetoric and belles lettres at Dc.3.42, and sermons from 1800 at Dc.3.43. Included in the collection too are letters (one probably to Lord Keith, 1789), another from 1783, and a note to Dr. Archibald Davidson, 1788, at E95.60, E89.74, and E99.11.
