Rue des Bauches, opening out of it, still narrow and quaint, was in olden days a lane through the _Bauches_, a word signifying a marshy tract or used to designate hut-like dwellings on waste, perhaps marshy land. Passy had within its bounds the Hautes Bauches, and the Basses Bauches. We of the 16th arrondissement know the street nowadays more especially as that of the tax-paying office. Rue de l’Assomption marking the boundary between Passy and Auteuil began as Rue des Tombereaux. The convent of the Assomption is a modern building (1858), in an ancient park. The old château there, so secluded on its tree-surrounded site as to go by the name of l’Invisible, rebuilt in 1782, was for a time the home of Talleyrand, later of the actress Rachel, of Thiers, the statesman, of the comtesse de Montijo, mother of the Empress Eugénie; the nuns came here from Rue de Chaillot in 1855. No. 88 is an old convent-chapel used as chapel of ease for Passy. In Avenue de Mozart we see modern structures only, but old-time streets open out of it at intervals. It was in a house in Rue Bois-le-Vent, near the château de la Muette, that André Chenier was arrested in 1794. Behind No. 13, of Rue Davioud we find traces of an old farmyard and a well. Rue de la Cure refers by its name to the iron springs once there. Rue de Ribéra is the ancient Rue de la Croix. Rue de la Source, was in old days Sente des Vignes. Benedictine nuns from St-Maur settled there in 1899 to be banished or laicized a few years later. Rue Raffet dates from the eighteenth century as Rue de la Grande Fontaine. Rue du Docteur Blanche, named to memorize the organizer of the well-known private asylum in the _hôtel_ once the dwelling of princesse de Lamballe, is the ancient Fontis Road. Rue Poussin, and the short streets connected with it, all date from the middle of the nineteenth century, opened by the railway company of the Ceinture line in the vicinity of their station at Auteuil. Rue des Perchamps, once Pares Campi, crosses the site of the ancient cemetery of the district. In Rue la Fontaine, in olden days known for its fountain of pure water, we find here and there an eighteenth-century building among the garden-surrounded houses. In Rue Théophile Gautier, a tennis-court and tall houses let in flats cover the ground where till 1908 stood the Château de Choiseul-Praslin, in its latter years, till 1904, a convent of Dominican nuns. Rue de Remusat runs along the course of the ancient Grande Rue; Rue Félicien-David was the first street flooded in the great inundation of 1910.[H] The street became a river three mètres deep. Rue Wilhem, of so commonplace an aspect to-day, dates from the eighteenth century, when it was Sentier des Arches, then Rue Ste-Geneviève. Place d’Auteuil, until 1867 Place d’Aguesseau, is on the site of the churchyard of past days. The monument we see there was set up to the memory of D’Aguesseau and his wife by command of Louis XV, in 1753. This is the highest point in the district,
