The view from this bridge up the Seine, upon the islands below mount St. Catharine, is quite enchanting. Upon the quay, although it was Sunday, a vast number of people were dancing, drinking, and attending shows and lotteries. Here were people of various nations, parading up and down in the habits and dresses of their respective countries, which produced quite the effect of a masquerade. The river Seine is so deep at this place, that ships of three hundred tons burden are moored close to the quay, and make a very fine appearance. The exchange for the merchants is parallel with the centre of the quay, and is a long paved building of about 400 feet in length, open at top, having a handsome iron balustrade, and seats towards the Seine, and a high stone wall towards the town. Over all the great gates of the city, is written, in large characters, "Liberty, Equality, Humanity, Fraternity or Death:" the last two words have been painted over, but are still faintly legible. In the evening we went to the french opera, which was very crowded. The boxes were adorned with genteel people, and many beautiful young women. The theatre is very large, elegant, and handsome, and the players were good. I was struck with the ridiculous antics, and gestures of the chef in the orchestra, a man whose office it is to beat time to the musicians. In the municipality box which was in the centre, lined with green silk, and gold, were two fine young women who appeared to be ladies of fashion, and consequence; they were dressed after the antique, in an attire which, for lightness, and scantiness I never saw equalled, till I saw it surpassed at Paris. They appeared to be clothed only in jewels, and a little muslin, very gracefully disposed, the latter, to borrow a beautiful expression, had the appearance of "woven air."--From emotions of gratitude, for the captivating display which they made, I could not help offering a few fervent wishes, that the light of the next day might find them preserved from the dreaded consequences of a very bitter cold night. Rouen, upon the whole, is a fine city, very large, and populous. It was formerly the capital of the kingdom of Normandy. It stands upon a plain, screened on three sides, by high, and picturesque mountains. It is near two leagues in compass, exclusive of the fauxbourgs of St. Severs, Cauchoise, Bouveul, St. Hiliare, Martainville and Beauvisme. Its commerce was very celebrated, and is returning with great rapidity. Most of the fine buildings in this city, and its environs are Anglo-Norman antiquities, and were founded by the English before they left Normandy. The cathedral is a grand, and awful pile of gothic architecture, built by our William the Conqueror. It has two towers, one of which, is surmounted by a wooden spire covered with lead, and is of the prodigious height of 395 french feet, the other is 236 feet high.
