Morning at the Office. Received a letter from my Aunt Smith,1 instead of the usual one from my Mother, to inform me she was unwell. I had been apprehensive of this. My own customary letter was written notwithstanding and occupied me a large part of the morning. Remainder, reading Massachusetts Reports and Statutes. Afternoon, Mr. Burke upon the Regicide Peace. Evening at the Debating Society. Heard a very smart and spirited argument upon the subject of closing the Post Office on Sunday. At times, there was much piquancy, and some disagreeable personality, but it was on the whole, the most interesting debate I have witnessed. The subject is one at present agitating the Community, and many petitions are in circulation for the purpose of forcing Congress into Legislation upon it.
