I have left that Pawtuxet place forever, and we must extirpate everything existing there, alive or dead. I shall not go there again, and you must not believe it if you ever hear that I am there. I will tell you why I say this when I see you. I have come home for good, and wish you would call on me at the very first moment that you can spare five or six hours continuously to hear what I have to say. It will take that long—and believe me when I tell you that you never had a more genuine professional duty than this. My life and reason are the very least things which hang in the balance.
