Sir, - It may probably occur to you that we have met, and visited, and conversed; on my side, with interest. You may remember that you have done me several courtesies, for which I was prepared to be grateful. But there are duties which come before gratitude, and offences which justly divide friends, far more acquaintances. Your letter to the Reverend H. B. Gage is a document which, in my sight, if you had filled me with bread when I was starving, if you had sat up to nurse my father when he lay a-dying, would yet absolve me from the bonds of gratitude. You.
