The Life of Sir James Mackintosh
“The Life of Sir James Mackintosh”“How beautiful, how purely intellectual, this friendship was, may be best felt from reading the two letters Sir James wrote many years after to Robert Hall upon his recovery from derangement.”
Fuller, Margaret. Art, Literature, and the Drama. Edited by Arthur B. Fuller. New York: The Tribune Association, 1869. · p57
Inferred Fuller names Hall but not the work — “…om reading the two letters Sir James wrote many years after to Robert Hall upon his recovery from derangement.” — so the identification as letters is the editor’s and is not confirmed by this passage alone.
