There is further correspondence regarding Manning being executor of Tuthill's will which includes letters between Manning and Tuthill's daughter, Laura (1835-1836)

Draft of a letter to the Editor of the Quarterly Review with an article concerning the publication of a pamphlet "Expostulations on the Iniquity of the present spy system" by Jacob Bray. The article attacks the author's knowledge particularly concerning spies in France during the Napoleonic conflict. The letter is signed D.L. but appears to be in Manning's hand. The pamphlet was published in 1818 which suggests the letter and article are of that date. Addressed to Mr Murray, bookseller, Albemarle Street, for the Editor of the Quarterly Review. Handwritten, 1 piece, 3 sides
