From the book:

In one of the finest houses of the rue Neuve-des-Mathurins, at half-past eleven at night, two young women were sitting before the fireplace of a boudoir hung with blue velvet of that tender shade, with shimmering reflections, which French industry has lately learned to fabricate. Over the doors and windows were draped soft folds of blue cashmere, the tint of the hangings, the work of one of those upholsterers who have just missed being artists. A silver lamp studded with turquoise, and suspended by chains of beautiful workmanship, hung from the centre of the ceiling. The same system of decoration was followed in the smallest details, and even to the ceiling of fluted blue silk, with long bands of white cashmere falling at equal distances on the hangings, where they were caught back by ropes of pearl. A warm Belgian carpet, thick as turf, of a gray ground with blue posies, covered the floor. The furniture, of carved ebony, after a fine model of the old school, gave substance and richness to the rather too decorative quality, as a painter might call it, of the rest of the room. On either side of a large window, two etageres displayed a hundred precious trifles, flowers of mechanical art brought into bloom by the fire of thought.
