Read it through once

Presently the chambers gave up their fair tenants one after another: each came out gaily and airily, with dress that gleamed lustrous through the dusk. For a moment they stood grouped together at the other extremity of the gallery, conversing in a key of sweet subdued vivacity: they then descended the staircase almost as noiselessly as a bright mist rolls down a hill. Their collective appearance had left on me an impression of high-born elegance, such as I had never before received.
