“By profiting by my counsels. Ambrosio, I live but to serve you: your interest and happiness are equally mine. Be your person Antonia’s, but to your friendship and your heart I still assert my claim. Contributing to yours forms now my only pleasure. Should my exertions procure the gratification of your wishes, I shall consider my trouble to be amply repaid. But let us lose no time. The liquor of which I spoke is only to be found in St. Clare’s laboratory. Hasten then to the prioress; request of her admission to the laboratory, and it will not be denied. There is a closet at the lower end of the great room, filled with liquids of different colours and qualities. The bottle in question stands by itself upon the third shelf on the left. It contains a greenish liquor: fill a small phial with it when you are unobserved, and Antonia is your own.”
