In Rue des Fossés St-Bernard, stretching along the line of Philippe-Auguste’s wall, between the site of two great gates: Porte St-Victor, a spot desecrated by the massacres of September, and Porte St-Bernard, we see Halle-aux-Vins, where abbey buildings stood of yore. The Halle-aux-Cuirs, in Rue Censier, is on the site of the famous orphanage “La Miséricorde,” called vulgarly “les Cent Filles” or “les Cent Vierges.” The apprentice from the Arts and Crafts Institution, who should choose one of these orphan maidens for his wife, obtained as her dowry the privilege of becoming at once a full member of the Corporation. In Rue de la Clef we have at No. 56 the site of part of the notorious prison Ste-Pélagie. No. 26 is still owned by the Savouré, whose ancestors kept the school where Jerôme Bonaparte and many of his compeers were educated. Rue du Fer-à-Moulin, dating from the twelfth century, a stretch of blackened walls, has been known by many names. In the little Rue Scipion leading out of it we see at No. 13 the _hôtel_ built in the sixteenth century for the Tuscan, Scipion Sardini, who came to France in the suite of Catherine de’ Medici, a rich and rather scandalous financier; terra-cotta medallions ornament its walls. It serves now as the bakehouse of the Paris hospitals. In the square opposite we see the curious piece of statuary: “des Boulangers,” by Charpentier. Rue Monge, running from boulevard St-Germain to Avenue des Gobelins, was cut through old streets of the district in 1859. A fountain Louis XV brought here from its original site, Rue Childebert, was set up in the square, and many other old-time relics: statues from the ancient hôtel de Ville, débris from the Palais de l’Industrie, burnt down in 1897; a copy of the statue of Voltaire by Houdin, etc. Rue d’Arras, so named from a college once there, began as Rue des Murs, referring to the walls of Philippe-Auguste. The concert hall we see was not long ago Père Loyson’s church. L’École Communale, No. 19 Rue des Boulangers, is on the site of part of the convent des “Filles Anglaises,” which had existed there from 1644--razed in 1861. Rue Rollin began in the sixteenth century as Rue des Moulins-à-vent. On the site of the house at No. 2 Pascal died in 1662. No. 4, with its fine staircase, its _grille_ and ancient well in the courtyard, was the home of Bernardine de St. Pierre, during the years he wrote his world-known _Paul and Virginie_. Rollin lived and died (1741) at No. 8. Descartes lived at No. 14. When the street was longer and known as Rue Neuve-St-Etienne, Manon Philipon, Madame Roland of later days, was a pupil in the _annexe_ of the English Augustine convent on a site crossed now by Rue Monge and Rue de Navarre.
