The marquise was a close friend of the principal French researcher into electricity, Charles Du Fay, keeper of the Jardin du Roi in Paris. She also studied Newton’s General Scholium of 1713, in which he referred to his “electric spirit.” Mme du Châtelet died far too young, in childbirth in 1749 while in her early forties. One of the might-have-beens of Franklin’s career is this: if the marquise had lived to read his electrical essays, would the two have met, and what would have been the consequences?

6. Clymer’s fire: PG, January 13, 1743.
7. The fire engine came from Richard Newsham’s workshop in Cloth Fair, London, just around the corner from the printing shop at St. Bartholomew the Great, where Newsham started to manufacture his “new invented perpetual water engine to quench fire” in 1721: Applebee’s Weekly Journal, November 4 1721.

11. Bartram, Collinson, Grace, and Franklin: E. and D. S. Berkeley, The Correspondence of John Bartram, 1734–1777 (Gainesville, FL, 1992), pp. 43, 49, 63–64, 79, 99, 106, 188–89, and 214.
12. BFP 2, pp. 378–83. The standard account of the society’s early days is still Carl Van Doren, “The Beginnings of the American Philosophical Society,” in Proceedings of the American Philosophical Society 87 (1944): 437–62, but Van Doren did not see the connections between the society and the crisis in Indian affairs in 1743. In general, and despite the brilliance of his writing, Van Doren had a tendency to neglect the wider political and economic circumstances of Franklin’s work in Philadelphia. On the new sophistication of material culture in Pennsylvania in the early 1740s: Mark Reinberger and Elizabeth McLean, The Philadelphia Country House: Architecture and Landscape in Colonial America (Baltimore, 2015), pp. 70–78.

18. Franklin to Jane Mecom, July 28, 1743, BFP 2, p. 384–85.
19. Spencer’s description: London Evening Post, April 14–16, 1743. Genealogical records from Scotland contain a reference to an Archibald Spence born at Jedburgh on July 10, 1700, the son of a tobacco spinner, and this is probably our man.
20. London career of Spencer, and lectures by Desaguliers: London Evening Post, March 16–18, 1736, December 1–4, 1739, February 26–28, 1741, and November 19–21, 1741; and Daily Advertiser, November 29, 1742. His career and reputation in America: J. A. L. Lemay, “Franklin’s ‘Dr Spence’: The Reverend Archibald Spencer (1698?–1760), MD,” in Maryland Historical Magazine 59, no. 2 (June 1964): 199–216. Spencer obtained his medical degree from St. Andrews University in October 1739 by providing testimonials from two physicians who belonged to the Royal Society: William Stukeley, often regarded as the founder of British archaeology, and Robert Taylor, who was one of the king’s doctors: St. Andrews University Library, Special Collections, UY 350/28.
21. Details of Spencer’s American lectures: I. Bernard Cohen, “The Mysterious ‘Dr Spence,’ ” in his Benjamin Franklin’s Science (Cambridge, MA, 1990). His brick church—All Hallows—is still standing at South River, Maryland, not far from Annapolis. With the help of the Sunday congregation I tried in vain to find his grave in the churchyard; and so it may be that Archibald Spencer lies buried beneath the floor of the building.
22. Electrical experiments in the 1730s, and the life and work of Du Fay: Fontenelle, “Éloge de Du Fay,” in Histoire de l’Académie Royale des Sciences, 1739 (Paris, 1741); Henri Becquerel, Notice sur Charles-François de Cisternay Du Fay (Paris, 1893); and the superb modern account by J. L. Heilbron, Electricity in the Seventeenth and Eighteenth Centuries: A Study of Early Modern Physics (Berkeley, CA, 1979), Vol. 1, Chapters 8 and 9.
23. Just as there is no full-length modern scholarly biography of James Logan, the same is true in the case of Cadwallader Colden. The most recent study is John M. Dixon’s book, The Enlightenment of Cadwallader Colden: Empire, Science, and Intellectual Culture in British New York (Ithica, NY, 2016), but it is relatively brief. Colden’s correspondence was published by the New-York Historical Society a century ago, but without adequate annotation or commentary. The relevant volumes are The Letters and Papers of Cadwallader Colden, Vol. 1 (1711–1729) (NYHS, 1917); Vol. 2 (1730–1742) (NYHS, 1919); and Vol. 3 (1743–1747) (NYHS, 1920).
24. American science in the 1730s: Raymond S. Stearns, Science in the British Colonies of America (Urbana, IL, 1970), pp. 502–14, with also a brief account of Colden’s work on pp. 491–97.

After James Alexander was named as New Jersey’s surveyor general in 1718, he delegated the work involved to a deputy, Franklin’s old Burlington friend Isaac Decow, who held the post until his death in the 1740s: see note 15 to Chapter 12.

21. Timing of Franklin’s visit to Boston: Lemay 2, pp. 316–17. Publication date of the American Magazine & Historical Chronicle: Boston Evening Post, November 10, 1746, referring to the article titled “Electrical Phenomena Produc’d at Paris and the Apparatus Described.” Of the nineteen items in the October issue, every one was lifted verbatim from the British monthlies.
22. Le Monnier’s full-length account of his experiments appeared as Recherches sur la communication de l’électricité in the 1746 edition of the Histoire et mémoires de l’Académie Royale des Sciences. The condensed version by Father Needham was dated July 4, 1746, and addressed to Martin Folkes, president of the Royal Society. After appearing in the July Gentleman’s Magazine (Vol. 16, pp. 371–74), it was separately published in London at the end of September, before its formal reading at the Royal Society on October 23: see London Evening Post, September 27–30, 1746, and John Turberville Needham, “A Letter…Concerning some New Electrical Experiments Lately Made at Paris,” in the Royal Society’s Philosophical Transactions 44 (1746–47), pp. 247–63. See also Heilbron, Electricity in the Seventeenth and Eighteenth Centuries, Vol. 2, pp. 316–21; and Lemay 3, pp. 65–67. Their account of the beginning of Franklin’s experiments differs from mine by leaving out the decisively important influence of Le Monnier.
