I have had three or four sleepless nights this weeks, and for the little rest I have enjoyed I have been indebted to soporific draughts. I dined this day with Mr. Parsons with Bridge and with Foster who took his station in the office on Thursday. This afternoon I mounted a horse and went to Haverhill where I am determined to spend a few days, and see if I cannot recruit my health. I found H. Lincoln here.
