JA's sudden decision to go to London himself and take his family directly to Paris without a pause of some weeks at The Hague, was prompted by the news of Jefferson's arrival in Europe a month or so before JA expected him; see JA to AA, 1 Aug. (Adams Papers), and Jefferson to JA, “On board the Ceres off Scilly,” 24 July (Adams Papers; Jefferson, Papers, ed. Boyd, 7:382–383, with note quoting JA's expressions of pleasure in the appointment of Jefferson as a fellow commissioner).

In JA's accounts as settled by Congress there appears the following entry:

“Expences of his Removal with his Family from the Hague & London to Auteuil in August 1784 including extra Expences of Carriages, Post Horses, Passages by Sea from Helvoet to Harwich & from Dover to Calais &c. £100.... Purchase of a Carriage in London. £120” (DNA: RG 39, Foreign Ledgers, Public Agents in Europe, 1776–1787, p. 267).
