Philadelphia 29. April 1781
I beg pardon for delaying so long to return a thousand thanks to your Excellency for your polite & obliging Letter of February 14th.
Since I left the public service I flatter myself I have been useful in qualifying young gentlemen for your hospitals & army as well as for private life—I impatiently wait to execute any commands you may still honor me with, & beg your & your good Ladys acceptance of my most affectionate compliments & best wishes. I am with unremitting zeal & Esteem Your Excellencys very humb. & obedt Servt
