Somerville’s letter of 22 Nov. 1791, recorded in SJL as received 22 Nov.1791, has not been found. George Skene Keith’s Pamphlet: Tracts on Weights, Measures, and Coins (London, 1791). See No. 3766. TJ subsequently disparaged this work, critical of his advocacy of the rod pendulum as a standard of measure, as vague and imprecise (TJ to David Rittenhouse, 8 June 1792).
