Included in the collection is an autograph letter signed from Jean-Rodolphe Vautravers to Benjamin Franklin, dated 21 September 1777. The letter begins by discussing electrical experiments exhibited at Zurich by the Chevalier de Volta of Como before moving on to discuss the contemptuous treatment of the republics of Switzerland by the present rulers of Great Britain. Vautravers notes that he encloses the fruit of his neglect and adds to it a copy of verses sent by Voltaire to [Charles Gravier,] Comte de Vergennes. The conclusion of the letter turns to diplomacy, with Vautravers noting that His Excellency is to proceed to Venice to secure that republic in the Bourbonian interest, having already secured Portugal. There is a brief discussion of the attitude of Russia toward Hanover, and Vautravers provides proofs of the Emperor’s aversion to republics. The letter concludes by noting that Franklin’s adversaries are now crowing over Burgoyne’s success in Canada.
