I could not sleep last night. Lay restless till about 3 in the morning. Then got up, and read one of Bishop Berkeley’s Dialogues against matter,1 a curious System, and rather a new one to me. At day light I went again to bed, and slept till eleven o’clock. In the afternoon I went down to see my Grand-mamma, but she was not at home.
