We the undersigned hereby certify that the foregoing statement is in the hand-writing of Abraham Lincoln. DAVID DAVIS. LYMAN TRUMBULL. CHARLES SUMNER.[E] [E] The circumstances under which the original preceding sketch was written are explained in the following letter:-- NATIONAL HOTEL, WASHINGTON, D. C., Feb. 19, 1872. COLONEL WARD H. LAMON: DEAR SIR,--In compliance with your request, I place in your hands a copy of a manuscript in my possession written by Abraham Lincoln, giving a brief account of his early history, and the commencement of that political career which terminated in his election to the presidency. It may not be inappropriate to say, that some time preceding the writing of the enclosed, finding, in Pennsylvania and elsewhere, a laudable curiosity in the public mind to know more about the early history of Mr. Lincoln, and looking, too, to the possibilities of his being an available candidate for the presidency in 1860, I had on several occasions requested of him this information, and that it was not without some hesitation he placed in my hands even this very modest account of himself, which he did in the month of December, 1859. To this were added, by myself, other facts bearing upon his legislative and political history, and the whole forwarded to a friend residing in my native county (Chester, Pa.),--the Hon. Joseph J. Lewis, former commissioner of internal revenue,--who made them the basis of an ably-written and somewhat elaborate memoir of the late president, which appeared in the Pennsylvania and other papers of the country in January, 1860, and which contributed to prepare the way for the subsequent nomination at Chicago the following June. Believing this brief and unpretending narrative, written by himself in his own peculiar vein,--and in justice to him I should add, without the remotest expectation of its ever appearing in public,--with the attending circumstances, may be of interest to the numerous admirers of that historic and truly great man, I place it at your disposal. I am truly yours, JESSE W. FELL.
