Isidoro Bianchi to the Abbé Martin Lefebvre de la Roche (unpublished)
Sunday morning, Paris
Monsieur,

I have the honor of sending you two portraits of Franklin, painted with electricity. I can only express my lively gratitude by my good will, and when I have something new in physics by which to express it to you. Monsieur Morel is staying at the Carriage Bureau in Versailles, near the Pont Royal, if you have a moment to send him a brief note. In the meantime, I am with all possible respect your very humble and obedient servant

I Bianchi

I beg you, my very humble respects to Madame Helvétius. ps If Monsieur Franklin would like to have the equipment to do the experiment, I can provide him with it.
Addressed: Monsieur Monsieur L'Abbé La Roche, at Madame Helvétius's in Auteuil [On the third page is a little portrait of Franklin, on silk]
