6. October 17 fell on a Saturday in both 1761 and 1767. Although BF, WF, and Richard Jackson returned from a journey to the Netherlands about Sept. 20, 1761, Collinson’s pleasure at hearing that BF had arrived “In the happy land of Liberty” sounds much more like the return to England from France on Oct. 8, 1767, than that from the Dutch Republic on September 20 of the earlier year. Collinson’s failure to mention WF, or to include him specifically in the invitation, tends to support the 1767 dating.
7. For Daniel Charles Solander, who had visited the Collinsons with BF during the previous July, see above, p. 215 n. A letter from Collinson to Solander, dated just as is this letter to BF and directing Solander to “concert Measures” with BF about going to Mill Hill, is among the Franklin Papers, APS.

9. Mounted at the same page in the Franklin Papers, APS, is an undated, unaddressed note signed by Collinson. It reads: “I thought the Abbe Nolets had been 3 Distinct books, but I find they are separate Books so have sent them all—have no time to look into them—So expect their Account from you.” This note certainly relates to Nollet’s Lettres sur L’Électricité (Paris, 1753), of which he sent three copies to William Watson to be forwarded to BF in March 1753; Watson delivered them to Collinson to be sent with a shipment of books for the Library Co. Had this note been identified in time it would have been printed as probably belonging to that month; see above, IV, 454, 457–8.
