Aristotle says, that the purple consists of three parts, the upper being the τράχηλος, or neck; the middle the μήκων, or poppy; and the lower the πυθμήν, or trunk; and that the juice lies between the first and second of these parts, or the throat. This juice, which Pliny calls “flos,” “flower,” “ros,” “dew,” and “succus,” “juice,” is distilled, Cuvier says, not from the fauces of the animal, but from the mantle or membranous tissue which lines the shell.
