It is in the gallery on the ground floor, that the merchants meet, when the rainy weather does not permit their meeting in the uncovered exchange: This was formerly the _Juridiction consulaire_; so its destination has not been changed since the tribunal of commerce is established here. In the middle of the gallery on the ground floor, and to the right on entering from the quay, we remark a handsome staircase, which is formed by a double flight of steps, from the first landing. Before the revolution, the statue of Louis XVth was placed here. This staircase leads up to the audience hall of the chamber of commerce, which is the most remarkable of the three rooms which compose the first floor of the building. It is ornamented, with a fine picture of Christ by Van Dyck. In one of the neighbouring rooms are two paintings of large dimensions, by Lemonnier, a native of Rouen. One of these paintings represents the audience given by Louis XVIth to the Chamber of commerce of Rouen, on the 28th june 1786, in the great hall of the archbishop's palace, called the _Salle des États_. All the figures are of natural size, and are striking likenesses. The subject of the other painting is allegorical. There are three different entrances to this edifice, one from the rue Nationale, another from the rue des Charrettes and a third from the Quay. THE CUSTOM-HOUSE. The edifice containing the ancient custom-house being a great deal too small and inconvenient for that purpose, it became indispensable to erect another building. For this object, the municipal administration opened a public competition on the 14th october 1833, for the erection of another edifice. In the month of may 1834, the preference was given to the plan of Mr Ed. Isabelle, a distinguished architect in Paris, who was charged with putting his plan into execution. The excavations were commenced on the 17th february 1835, in the presence of the mayor, the municipal council, etc., and the building was terminated in 1838.
