1. Autograph letter signed from James Mackintosh to Francis Horner, dated 12 December 1814: “On receiving your letter yesterday my first thought was to request you to call on Lady Mackintosh that she might read to you what I had written when the spontaneous communications of the duke of Wellington were fresh in my recollection. But on farther reflexion both on the unspeakable importance of the subject & on the just authority of your opinion I resolved to request an interview with him which passed this morning without any mention of your name. He behaved as he has always done in his Conversations with me on this matter with considerable apparent frankness & whatever his original opinions might have been he seemed to have a fair disposition to do his utmost in the discharge of his present Trust. The first act done by this Gove[r]nment in consequence of discussions with the D of W. tending to limit the renewed trade was a Circular letter from the Minister of Marine to the Maritime Prefects in the end of September instructing them to grant no ‘autorisations’ (I know no corresponding term in our English usages) to vessels fitted out for the Slave trade to the North of Cape Formosa. Several other communications in the following month to the Prefects & to the Armateurs of Nantes & Havre convey the same directive more or less forcibly but with the exp[re]ssion of a wish that the limitation should for the present not be much noised abroad. – On the 25th of Nov.r the D. of W. laid before the Minister of Marine a set of regulations for answering the observance of this limited prohibition [...] to declare all vessels & Cargoes coming from that part of the Coast, Prize – & all Slaves found on board any vessel within 40 leagues of the Shore between Cape Formosa & Cape Blanco not being part of the Crew of the Ship. To two of these regulations they objected – that relating to the payment of any sum to Capture on the ground of Poverty & to the Establishment of a hovering Act along the whole coast on the ground that it was nautically inconvenient for Ships to navigate at that Distance from Land between Cape Formosa & Cape Palmas. About a fortnight ago they communicated to the Duke? Projet de Reglement which is intended to be published by the King to carry into effect his Declaration of the 27th May be the immediate abolition of the Trade that part of the Coast where it had actually been abolished [...]”.

2. Autograph letter signed to Leonard Horner, after Francis Horner’s death in February 1817, dated 27 July 1817: “I am much gratified by your remembrance & shall thankfully return [...] Wilson’s letters when I have made a few Extracts from them. My letters to your Brother cannot be more agreeably to me placed any where than in your hands. – They should be so [... the] condition which you are so kind as to prepare if they had not as far as I can recollect highly related to private affairs which I was often led to consult him about from my confidence in his Judgements in his goodness to me. I shall look for letters written by him to me I send you in a day or two such as I can find – I think they were pretty frequent during the first part of my Residence in India – Lady Mackintosh & I’d be much gratified by seeing you here if it were only for a day or two on your return to Scotland – & if Mrs Horner too with you it would increase the gratification. You might get agreeably back into the Main Road by Stowe, Axford Blenheim & Warwick – Mrs Erskine is now at Malvern – she seems to have benefited by Cheltenham – But I fear she is scarcely yet qualified to return to India [...]”.
