'All the world and his wife' were there. Suddenly, there was a pressing toward one of the grand avenues. It was to see the King of Naples, who is now here on a visit to his aunt, the Queen of the French. The king and the French queen were in an open car, accompanied by two good-looking youths, about sixteen and eighteen, (the Dukes of Nemours and Orleans,) and the two princesses, rather pretty, and dressed with taste and marked simplicity. An elderly gentleman, next to the King of Naples, was said to be his minister or guardian, and he looks as if he needed one. He is a mustachioed, dandyish-looking fellow, and stared through his quizzing glass in a style quite amusing. The people took off their hats, as the car passed, but there was not a whisper of applause or enthusiasm. On our return, just as we stopped at the park of St. Cloud, the French king's carriage came up, kept as close as a prison; and in a few minutes, the queen and he of Naples arrived, and stopped in the park to change horses; so we had a chance to scan them all very closely. The queen might have been handsome once, but she certainly is not now. She bowed repeatedly to some one by the carriage; but not a word was uttered, which appeared very strange. * * * * * 10TH.--My way to Galignani's reading-room, every morning, is through the portico of the hall of the celebrated French Institute, over the Pont des Arts, and through the quadrangles of the Louvre and Palais Royal. What a world in miniature, (and not on a very small scale either,) is this Palais Royal! A palace that would _cover two or three of our squares_, in the heart of the city, was converted by its proprietor, the late Duke of Orleans, into an immense bazaar; the entrance from every part being from the interior court, which is a long promenade of itself, adorned with rows of trees, fountains, and gardens. The lower floor of the palace is divided into stores, in the arcade fashion, in which are displayed every article, almost, which can be imagined or desired, for use or ornament. The jewellers are the most numerous. There are, I should think, at least three or four hundred of these shops on the first floor, and they each rent for four thousand francs per annum. The second floor is occupied by cafés, reading-rooms and by gambling-establishments, or 'hells,' and the upper stories by characters of all sorts, male and female. In short, there is a specimen of every thing, good and bad, in this Palais Royal; and even the bad is made so alluring and dazzling, that altogether, it is no very difficult matter for an unwary novice there to rid himself of his superfluous cash. The imposing _coup d'oeil_ of the palace and gardens you can imagine better from the prints, than from any description. Near the Bourse, is the Halle au Blé, an immense circular building, the dome of which is nearly as large as that of the Pantheon at Rome. * * * * *
