Pleasure at reading Mrs Howorth's "enigmatically written" letter. His change of plans, now journeying to Montpelier, Genoa, and possibly Rome and Naples, before returning to London via Paris and Switzerland. Account of his "most agreeable jaunt" to the gardens and lands of Marquis de Giardin and tomb of [Jean-Jacques] Rousseau [(1712-1778), philosopher] and surrounding area, including an unfinished temple to modern philosophy, Rousseau's hut, and other monuments; they met Rousseau's widow, who showed them Rousseau's death mask. French literature and English translations; suggests Mrs Howorth's brother, Mr Lane, compiles a selection of French literature for schools, on plan of Enfield's speaker. Asks if Miss Louisa Lane has forgotten him [Mrs Howorth's sister].
