From Samuel Wharton
ALS: American Philosophical Society
Philada. August 30 1766
The Bearer hereof is Dr. Jonathan Potts son of your Friend John Potts Esqr. He pays Europe a Visit for an Improvement in the Duties of his Profession.2
He has requested me to mention his Name to you; Which I am persuaded, is all, that is Necessary, to introduce Him to Gentlemen of the first Character in the Physical Class. I did myself the Pleasure to call at your House a few Days ago and Miss Sally (Who this Moment passed my Window On Horse Back) was complaining She had missed the Packet—I therefore took Charge of the within Letter.3
My Partners and self are writing you a Letter to go by this Conveyance; But I am fearful We shall be too late.4 I am with the [since]rest Esteem and Respect Dear [Sir Your] Obli[g’d Friend] &c
Benjamin Franklin Esqr.
Addressed: To / Benjamin Franklin Esqr. / Deputy Post Master General / of North America / in Craven Street / London / per favor of / Dr. Jonathan Potts
2. On Jonathan Potts, his traveling companion Benjamin Rush, and their journey to Great Britain to pursue medical studies, see above, pp. 387–8. Young Potts had only just reached Edinburgh when he learned that his fiancée, Grace Richardson, was very ill, so he returned to Philadelphia at once. She had recovered by the time he reached home. They were married in the spring of 1767; he completed his medical studies at the College of Philadelphia, and she became the mother of his seven children. DAB.
3. No letter from Sally to her father of about this date has been found.
4. Presumably the letter of August 28, the next document but one above.
