[Footnote AC: The Emperor was very desirous that his correspondence with the allied sovereigns should be published. He wrote to Joseph from Saint Helena to secure their publication in the United States if possible. "It will be the best response," he said, "to all the calumnies which have been uttered against me." During Joseph's sojourn in England, he learned from Dr. O'Meara that the autograph originals of these letters addressed by Napoleon to the sovereigns had been offered for sale in London in the year 1822; that they had been in the hands of Mr. Murray, a well-known publisher; that the letters relating to Russia had been purchased by a diplomatic agent of that power for ten thousand pounds sterling. There was no longer any hope of obtaining them, since they were in the hands of those interested in having them destroyed.--_Memoires et Correspondence, Politique et Militaire du Roi Joseph, tome dixieme_, n. 231.] Joseph loved his brother tenderly, and he never could speak without emotion of the indignities and cruelties Napoleon suffered from that ungenerous Government to whose mercy he had so fatally confided himself. Anxious to do every thing which he thought might gratify the departed spirit of his brother, he implored permission of Austria to visit Napoleon's son, the Duke of Reichstadt, that he might sympathize with him in these hours of affliction. The Court of Austria refused his request. In 1824, Joseph's youngest daughter, the Princess Charlotte, left Point Breeze to join her mother in Europe, where she was to be married to Charles Napoleon Louis Bonaparte, the son of Louis and Hortense, and the elder brother of the present Emperor of the French. The tastes of Joseph inclined him to the country, and to its peaceful pursuits. He had, however, a city residence in Philadelphia, where he usually passed the winters. While thus residing on the banks of the Delaware, sadly retracing the memorable events of the past and recording its scenes, he received a proposition which surprised and gratified him. A deputation of Mexicans waited upon him at Point Breeze, and urged him to accept the crown of Mexico. The former King of Naples and of Spain in the following terms responded to the invitation: "I have worn two crowns. I would not take a single step to obtain a third. Nothing could be more flattering to me than to see the men who, when I was at Madrid, were unwilling to recognize my authority, come to-day to seek me, in exile, to place the crown upon my head. But I do not think that the throne which you wish to erect anew can promote your happiness. Every day I spend upon the hospitable soil of the United States demonstrates to me more fully the excellence of republican institutions for America. Guard them, then, as a precious gift of Providence; cease your intestine quarrels; imitate the United States and seek from the midst of your fellow-citizens a man more capable than I am to act the grand part of Washington."[AD]
