Went into the library, and took out one Volume of Wolff’s mathematics.1 Charles went to Boston: this evening Cranch returned from Braintree: we had a class meeting this evening, and voted to present a petition for a private Commencement to the overseers, who are to meet next Tuesday. I was desired, with Barron and Packard to draw up the petition. The meeting was adjourned to monday night.
