The manuscript is in the Harry Ransome Research Center, University of Texas at Austin, and is stated to have been ‘removed from a copy of Essays Moral, Philosophical and Political (London: 1772) by John Mills’. The application of a rigidly mathematical approach to questions of political economy is especially characteristic of De Quincey’s Westmorland Gazette period, so it may be that the manuscript dates from around 1819, but this is by no means certain.
