Such was this quarter in the last century. The Revolution snubbed it soundly. The republican government demolished and cut through it. Rubbish shoots were established there. Thirty years ago, this quarter was disappearing under the erasing process of new buildings. Today, it has been utterly blotted out. The Petit-Picpus, of which no existing plan has preserved a trace, is indicated with sufficient clearness in the plan of 1727, published at Paris by Denis Thierry, Rue Saint-Jacques, opposite the Rue du Plâtre; and at Lyons, by Jean Girin, Rue Mercière, at the sign of Prudence. Petit-Picpus had, as we have just mentioned, a Y of streets, formed by the Rue du Chemin-Vert-Saint-Antoine, which spread out in two branches, taking on the left the name of Little Picpus Street, and on the right the name of the Rue Polonceau. The two limbs of the Y were connected at the apex as by a bar; this bar was called Rue Droit-Mur. The Rue Polonceau ended there; Rue Petit-Picpus passed on, and ascended towards the Lenoir market. A person coming from the Seine reached the extremity of the Rue Polonceau, and had on his right the Rue Droit-Mur, turning abruptly at a right angle, in front of him the wall of that street, and on his right a truncated prolongation of the Rue Droit-Mur, which had no issue and was called the Cul-de-Sac Genrot.
