Perfume  

"Scents, like sounds, appear to influence the olfactory nerve in certain definite degrees. There is, as it were, an octave of odors like an octave in music; certain odors coincide, like the keys of an instrument. Such as almond, heliotrope, vanilla, and orange-blossoms blend together, each producing different degrees of a nearly similar impression. Again, we have citron, lemon, orange-peel, and verbena, forming a higher octave of smells, which blend in a similar manner. The metaphor is completed by what we are pleased to call semi-odors, such as rose and rose geranium for the half note; petty grain, neroli, a black key, followed by fleur d'orange. Then we have patchouli, sandal-wood, and vitivert, and many others running into each other."--The Art of Perfumery (1855) by George William Septimus Piesse

"Peau d'Espagne may be mentioned as a highly complex and luxurious perfume, often the favorite scent of sensuous persons, which really owes a large part of its potency to the presence of the crude animal sexual odors of musk and civet. It consists of wash-leather steeped in ottos of neroli, rose, santal, lavender, verbena, bergamot, cloves, and cinnamon, subsequently smeared with civet and musk. It is said by some, probably with a certain degree of truth, that Peau d'Espagne is of all perfumes that which most nearly approaches the odor of a woman's skin; whether it also suggests the odor of leather is not so clear." --Studies in the Psychology of Sex, Volume 4

"There are perfumes that are fresh like children's flesh,
sweet like oboes, green like meadows
— And others, corrupt, rich, and triumphant,
having the expansiveness of infinite things,
like amber, musc, benzoin, and incense,
which sing of the raptures of the soul and senses."--"Correspondances" by Baudelaire
