While this was the state of affairs with reference to the immediate relations of the two countries, Lord Palmerston was urging France into a coöperation with the four other leading powers of Europe in the adoption of a policy, by the negotiation of the quintuple treaty, which would have left the United States in a position of dangerous insulation on the subject of the great maritime question of the day. At this juncture, a change of administration occurred in England, subsequent but by a few months to that which had taken place in the government of the United States. Lord Melbourne's government gave way to that of Sir Robert Peel in the summer of 1841; it remained to be seen with what influence on the relations of the two countries. Some circumstances occurred to put at risk the tendency toward an accommodation, which might naturally be hoped for from a change of administration nearly simultaneous on both sides of the water. A note of a very uncompromising character, on the subject of the search of American vessels on the coast of Africa, had been addressed to Mr. Stevenson by Lord Palmerston on the 27th of August, 1841, a day only before the expiration of Lord Melbourne's ministry. To this note Mr. Stevenson replied in the same strain. The answer of Lord Aberdeen, who had succeeded Lord Palmerston as Secretary of State for Foreign Affairs, bears date the 10th of October, 1841, and an elaborate rejoinder was returned by Mr. Stevenson on the very day of his departure from London. Lord Aberdeen's reply to this note was of necessity addressed to Mr. Everett, who had succeeded Mr. Stevenson. It was dated on the 20th of December, the day on which the quintuple treaty was signed at London by the representatives of the five powers, and it contained an announcement of that fact.
