"Well," said he, "I think we must use a remedy which has hitherto succeeded. Magnetism will enable you to sleep, and perhaps will soothe your sufferings." Rising, then, he placed his hand on the patient's brow, as he had done a few months before when the Marquise had experienced such good effects from it. He placed his hands on the young girl's temples, and then made passes across her face, the result of which was that she sank softly to sleep. The state of somnambulism ensued, and Marie unfolded the condition of her heart to the young physician. While he was thus engaged the Duke entered. "You here, Doctor?" said he; "how imprudent!" "_She_ was suffering," said the physician; "now she sleeps." The Duke thanked Von Apsberg for his care, but seemed to centre all his hope in the young Doctor, as the sailor devotes himself to the lord of storms and waves. Now, though, every word the Duke said seemed a reproach. He shuddered as he thought of the confessions of Mlle. d'Harcourt, and asked himself if he participated in her sentiments or had suffered her to divine his. All his delicacy and loyalty revolted from the idea that this confession would cost the unfortunate father the life of his daughter.[5] Von Apsberg saw that henceforth it would be impossible for him to remain longer at the Duke's hotel, and that it would be criminal to remain with one the secret thoughts of whom he knew. He, therefore, made up his mind to speak to the Duke. Just then Marie, who had been for some time free from any magnetic influence, awoke calm and smiling. "How deliciously I have slept," said she; "how well I am!" The Duke kissed her affectionately. He said, "All this you owe to the Doctor; and I thank heaven amid our misfortunes that he has been preserved to us. I am glad I have been able to rescue him from his persecutors, and preserve my daughter's health by means of his own watchful care." Marie gave the Doctor her hand. The young girl did not remember what she had said while she slept. This slumber of the heart, however, could not last, and the young Doctor knew it. He resolved on the painful sacrifice which, but for the waking of his patient, he would at once have communicated to the Prince. The reflections of the night confirmed the Doctor in the course he had resolved to adopt. On the next day he put on a long cloak, which disguised his stature, and went to the room of the Duke, after having also put on a wig which René often wore when he visited Matheus, and which the Duke had sent for to enable him in case of a surprise to leave unrecognized.
