Morning cold. Went to Meeting in Federal Street, and heard Mr. Emerson preach a Sermon upon Slander. Very good, more to the purpose than ten from Mr. Gannet. The good effect of these is palpable, that of others serves only to heat and inflame the community. After dinner, I went out to Medford and passed the day as usual. Abby was not well, and I myself felt a little head ache. Nothing remarkable.
