The chimneys of the houses in it are below your feet.

Opposite to the lowest flight of steps, there is a large old mansion facing you, with a spacious walled garden behind--and to the right of it.

In front of this garden, on the same side as the mansion, and with great boughs of trees sweeping over their lowly roofs, is a row of small, picturesque, old-fashioned cottages, not unlike, in degree and uniformity, to the almshouses so often seen in an English country town.

The Rue d'Isabelle looks as though it had been untouched by the innovations of the builder for the last three centuries; and yet any one might drop a stone into it from the back windows of the grand modern hotels in the Rue Royale, built and furnished in the newest Parisian fashion.
In the thirteenth century, the Rue d'Isabelle was called the Fosse-aux- Chiens; and the kennels for the ducal hounds occupied the place where Madame Heger's pensionnat now stands.

A hospital (in the ancient large meaning of the word) succeeded to the kennel.
