5. Edward Nairne (1726–1806), F.R.S., 1776, was an English electrician and instrument maker. In 1774 he published a paper showing the superiority of pointed lightning rods over rounded ones, thus supporting BF in his controversy with Benjamin Wilson. BF bought various things from Nairne during his first mission and on Sept. 6, 1765, during his second mission purchased an “Achromatic prospective Glass with two Eye Glasses in one Slider that Magnifies Different,” a set of “6 Inch Magnetts in Mahogany Case,” and an “Electrical Machine with 6 Inch Globe in a plain box.” DNB; “Account of Expences,” pp. 5, 41; PMHB, LV (1931), 104, 121; Nairne to BF, Sept. 6, 1765. APS.
6. These directions have not been found, but they may relate to an “Electrical Air-thermometer” which Ebenezer Kinnersley “contrived” and described to BF in a letter of March 12, 1761; see above, IX, 286–9.
7. John Canton, the English electrical experimenter; see above, IV, 390 n.
