The doctor tells the patient that he has been poisoned, and the patient is delirious. The doctor tries to calm the patient down, but the patient's involuntary movements are too intense for him to do so. He suggests that the patient should be given morphine to treat his seizures. The patient is too weak to take morphine, so the doctor prescribes a different type of morphine, which is more effective in treating seizures. When the patient regains consciousness, he thanks the doctor for stopping him from killing the butcher.
