"I have great reason to doubt the truth of the anecdote you give (Appendix, p. 85, of your Memoirs) of Cunningham the poet (without an e). I knew him personally toward the latter part of his life, when those moderate sacrifices you speak of, had totally disqualified him from writing pastorals. His first and best pieces were produced before he had acquired that pernicious habit which impaired his faculties and shortened his days. Whiskey may inspire, but I will never believe that gin does."
