FAILLE & BOUCHOT, Parisian perfumers who failed in 1818. They gave an order for ten thousand phials of peculiar shape to hold a new cosmetic, which phials Anselme Popinot purchased for four sous each on six months' time, with the intention of filling them with the "Cephalic Oil" invented by Cesar Birotteau.
