Discusses the education of the son of a mutual friend [possibly named Sumner or Summer], whose legitimacy is suspect. Writes, "I am afraid whether I have any thing in writing that acknowledges him as his Son & that he ment [sic] to consider him as such with respect to his property." Forwards a letter from Dr. [William] Eustis concerning his desire to "have the charge of the Invalids" in Massachusetts (not present). Speaks highly of Eustis's integrity, and suggests Knox may want to appeal to Colonel [Alexander] Hamilton on Eustis's behalf, as Hamilton will be making the appointment. Mentions balls and parties being held in the area, and wishes that Knox's daughter Lucy was in Boston to attend it. Adds, "I believe I drank too much wine yesterday, as I have a most severe headache this day - I can hardly see the paper on which I am writing." Includes "post" written on the address leaf. A note on the address leaf declares that the enclosure from Dr. Eustis had been given instead to Dr. [Andrew] Craigie to pass along to Knox.
