The fullest account we possess of the life of Adam Smith is still the memoir which Dugald Stewart read to the Royal Society of Edinburgh on two evenings of the winter of 1793, and which he subsequently published as a separate work, with many additional illustrative notes, in 1810. Later biographers have made few, if any, fresh contributions to the subject. But in the century that has elapsed since Stewart wrote, many particulars about Smith and a number of his letters have incidentally and by very scattered channels found their way into print. It will be allowed to be generally desirable, in view of the continued if not even increasing importance of Smith, to obtain as complete a view of his career and work as it is still in our power to recover; and it appeared not unlikely that some useful contribution to this end might result if all those particulars and letters to which I have alluded were collected together, and if they were supplemented by such unpublished letters and information as it still remained possible to procure. In this last part of my task I have been greatly assisted by the Senatus of the University of Glasgow, who have most kindly supplied me with an extract of every passage in the College records bearing on Smith; by the Council of the Royal Society of Edinburgh, who have granted me every facility for using the Hume Correspondence, which is in their custody; and by the Senatus of the University of Edinburgh for a similar courtesy with regard to the Carlyle Correspondence and the David Laing MSS. in their library. I am also deeply indebted, for the use of unpublished letters or for the supply of special information, to the Duke of Buccleuch, the Marquis of Lansdowne, Professor R.O. Cunningham of Queen's College, Belfast, Mr. Alfred Morrison of Fonthill, Mr. F. Barker of Brook Green, and Mr. W. Skinner, W.S., late Town Clerk of Edinburgh.
