"In their own way they are the most luxurious of people, but all their luxuries are innocent. They may be said to dwell in an atmosphere of music and fragrance. Every room has its mechanical contrivances for melodious sounds, usually tuned down to soft-murmured notes, which seem like sweet whispers from invisible spirits. They are too accustomed to these gentle sounds to find them a hindrance to conversation, nor, when alone, to reflection. But they have a notion that to breathe an air filled with continuous melody and perfume has necessarily an effect at once soothing and elevating upon the formation of character and the habits of thought. (Ch. XV)"
