Having been notified yesterday that Mr T B. Potter would come today to present a copy of the resolutions adopted by the Union and Emancipation Society of Manchester, it is forwarded to the President, I went to town, and seized the opportunity to visit the Messr Baring in the City to do some business. Mr Sturgis alluded to the rumor which has become current of my departure, and expressed complimentary regret. On my return Mr Potter came, and spent an hour in conversation. He has been a most efficient friend to America in organizing all the sentiment favorable to us at a time when the Ministry were by no means fixed in their policy. He is of the radical school in politics, and very justly connects the issue of our struggle with the chances of progress in this Kingdom. The instincts of the aristocracy have proved a way to guide them a similar conclusion without the need of reasoning. The remainder of my daylight was devoted to writing droughts of Despatches, and a note to Lord Russell who has tried his hand again at a throw in the case of the Alabama. I fancy he gains little by his motion. Home at four o’clock. I am led constantly to notice the difference between the foggy, misty atmosphere of London and the clear though humid temperature at Hanger Hill. A distance of not more than five miles. Quiet evening at home.
