By 1870 the edifice had become known as the Palais du Senat, then as the headquarters of the Prefecture of the Seine, and finally, as to-day, the Palais du Luxembourg, the seat of the French Senate and the residence of the president of that body. The principal public apartments are the Library, the "Salle des Seances," the "Buvette"--formerly Napoleon's "Cabinet de Travail," the "Salle des Pas Perdus"--formerly the "Salle du Trone," the Grand Gallery and the apartments of Marie de Medici. The chapel is modern and dates only from 1844. The Palais du Petit Luxembourg is the official residence of the president of the Senate and dates also from the time of Marie de Medici. The picture gallery is housed in a modern structure to the west of the Petit Luxembourg. [Illustration] The facade of the Palais du Senat is not altogether lovely and has little suggestion of the daintiness of the Petit Luxembourg, but, for all that, it presents a certain dignified pose and the edifice serves its purpose well as the legislative hall of the upper house. [Illustration: _The Petit Luxembourg_] The gardens of the Luxembourg form another of those favourite Paris playgrounds for nursemaids and their charges. It is claimed that the children are all little Legitimists in the Luxembourg gardens, whereas they are all Red Republicans at the Tuileries. One has no means of knowing this with certainty, but it is assumed; at any rate the Legitimists are a very numerous class in the neighbourhood. Another class of childhood to be seen here is that composed of the offsprings of artists and professors of the Latin quarter, and of the active tradesmen of the neighbourhood. They come here, like the others, for the fresh air, to see a bit of greenery, to hear the band play, to sail their boats in the basins of the great fountain and enjoy themselves generally. One notes a distinct difference in the dress and manners of the children of the gardens of the Luxembourg from those of the Tuileries and wonders if the breach will be widened further as they grow up. The Jardin du Luxembourg is all that a great city garden should be, ample, commodious, decorative and as thoroughly typical of Paris as the Pont Neuf. Innumerable, but rather mediocre, statues are posed here and there between the palace and the observatory at the end of the long, tree-lined avenue which stretches off to the south, the only really historical monument of this nature being the celebrated Fontaine de Medicis by Debrosse, the architect of the palace. It was a memorial to Marie de Medici. While one is in this quarter of Paris he has an opportunity to recall a royal memory now somewhat dimmed by time, but still in evidence if one would delve deep.
