Eau de Beauté, Eau de Paris sans pareille, or Eau de Princesses (August Renard, Paris); with a German title, “Rhümhehst bekanntes cosmetisches Wasser genannt Prinzessen-Wasser.” The well-known and renowned cosmetic called Princesses’ Water.’ To experience the brilliant effects of this marvellous fluid we need only, after washing, habitually pass a small sponge moistened with the fluid gently over the skin, and allow it to dry without rubbing. By so doing our complexion will remain white, smooth, clear, and soft, even to extreme old age. Those, however, who are troubled with freckles, heat-spots, or any other eruption should use the water several times a day as directed. They need suffer no longer from any defect of the skin. Princesses’ Water when shaken is a milk-white fluid contained in an oval bottle with a long neck, which holds 125 grammes. On standing it deposits a white precipitate. It is made from 2·5 grammes calomel, ·45 grammes corrosive sublimate (so altered by the added perfume that the usual tests do not reveal it), and 122 grammes orange-flower water.
