Porte Saint-Honor�; in the University from the Porte Saint-Victor to the Porte Saint-Germain. These two great thoroughfares intersected by the two first, formed the canvas upon which reposed, knotted and crowded together on every hand, the labyrinthine network of the streets of Paris.

In the incomprehensible plan of these streets, one distinguished likewise, on looking attentively, two clusters of great streets, like magnified sheaves of grain, one in the University, the other in the Town, which spread out gradually from the bridges to the gates.

Some traces of this geometrical plan still exist to-day.
