Geoffroy Saint-Hilaire pleased Audubon greatly and proved to him by his conversation that he understood perfectly the difference between the French and the English. The Duke of Orleans, who then occupied the Palais Royal, seemed to him the finest physical type of man he had ever met. "He had my book brought up," said the naturalist, "and helped me untie the strings and arrange the table, and began by saying that he felt great pleasure in subscribing to the work of an American, for he had been most kindly received in the United States and should never forget it." When the plate of the Baltimore Orioles was held up to view, the Duke exclaimed: "This surpasses all I have seen, and I am not astonished now at the eulogiums of M. Redouté." He conversed in both English and French, had much to say of American cities and rivers, and added: "You are a great nation, a wonderful nation." The Duke wrote his name in Audubon's subscription book, promised to try to enlist a number of the crowned heads of Europe in his behalf, and gave him besides a number of orders for pictures of animals. Audubon had already made friends with the veteran painter of flowers, Pierre Joseph Redouté, and when it was proposed that they should exchange works, the "Raphael of Flowers" consented, gave Audubon at once nine numbers of his _Belles Fleurs_, and promised to send "_Les Roses_." During this visit of eight weeks Parker painted portraits of both Cuvier and Redouté; Swainson worked steadily at the Museum, where Isidore Geoffrey Saint-Hilaire gave him the use of his private study; while Audubon, for the most part, was driving from post to pillar in his not altogether successful efforts to extend his subscription list. As already intimated, his greatest success in Paris was in winning the friendship and endorsement of Cuvier, who reported upon his work at a meeting of the Royal Academy of Sciences held on September 22.[362] Audubon has related how on this occasion he had an appointment to meet the Baron in the library of the Institute at precisely half past one o'clock; he waited; the hall filled, and the clock ticked on, but the great savant did not appear. Finally, said Audubon, after an hour had passed, "all at once I heard his voice, and saw him advancing, very warm and apparently fatigued. He met me with many apologies, and said, 'Come with me'; and as we walked along, he explaining all the time why he had been late, while his hand drove a pencil with great rapidity, and he told me that he was actually now writing the report on my work!"[363] Cuvier's published report, which was extremely laudatory, showed little signs of haste. After speaking of Audubon's talents and accomplishments he said:
