When your hand is dry, hold the vial open to my nostrils for two minutes by your watch.

By that time, I shall be asleep.

Put the vial in this pocket of my _caftan_; open all the doors and windows, and tell my servant to leave them so, but not to admit any one.

Then you can leave me; I shall sleep very comfortably.

Come back and wake me a little before midnight.
You will wake me easily by lifting my head and pressing one of my hands.
Remember, if you should forget to wake me, and I should still be asleep at one o'clock, I should never open my eyes again, and should be dead before morning.
