The cold made them clasp each other the tighter; their sighs seemed more profound; their eyes, though they could scarcely discern them in the gloom, seemed bigger; and in the stillness that enfolded them a word, softly murmured, would fall upon their hearts like the note of a crystal bell and pass, trembling with infinite vibrations, into silence.
— Flaubert, Madame Bovary, chapter 19
