Erskine's Preface (pp. x,āburnā xi) contains various other references to Leyden's work which indicate its quality as tentative and unrevised. It is now in the British Museum Library.
Little need be said here about the _Memoirs of Baber_.[24] Erskine worked on a basis of considerable earlier acquaintance with his Persian original, for, as his Preface tells, he had (after Leyden's death) begun to translate this some years before he definitely accepted the counsel of Elphinstone and Malcolm to undertake the _Memoirs_. He finished his translation in 1813, and by 1816 was able to dedicate his complete volume to Elphinstone, but publication was delayed till 1826. His was difficult pioneer-work, and carried through with the drawback of working on a secondary source. It has done yeoman service, of which the crowning merit is its introduction of Babur's autobiography to the Western world.
Amongst Erskine's literary remains are several bound volumes of letters from Elphinstone, Malcolm, Leyden, and others of that distinguished group of Scots who promoted the revival of Babur's writings. Erskine's grandson, the late Mr. Lestocq Erskine, placed these, with other papers, at our disposal, and they are now located where they have been welcomed as appropriate additions:—Elphinstone's are in the Advocates' Library, where already (1826) he, through Erskine, had deposited his own Codex—and with his letters are those of Malcolm and more occasional correspondents; Leyden's letters (and various papers) are in the Memorial Cottage maintained in his birthplace Denholm (Hawick) by the Edinburgh Border Counties Association; something fitting went to the Bombay Asiatic Society and a volume of diary to the British Museum. Leyden's papers will help his fuller biography; Elphinstone's letters have special value as recording his co-operation with Erskine by much friendly criticism, remonstrance against delay, counsels and encouragement. They, moreover, shew the estimate an accomplished man of modern affairs formed of Babur Padshah's character and conduct; some have been quoted in Colebrooke's _Life of Elphinstone_, but there they suffer by detachment from the rest of his Baburiana letters; bound together as they now are, and with brief explanatory interpolations, they would make a welcome item for "Babur Padshah's Book-pile".
