"'I have killed him, I have killed him,' she cried. "'Pardon me', said I, 'Monsieur Dervilly is in great danger; still if we knew the cause of this dreadful attack we might gain some advantage by it.' "'Ah, it is my work,' murmured the fair mystery to herself, without heeding my observation; 'I have done it, and if he dies, I am a murderer--_his_ murderer.' She appeared no way disposed to betray her secret, and I did not press the subject. Presently Louis came in. He made his inquiries of me, and then went to the patient. There was no change, except in the increase of fatal symptoms. The delirium was more furious, the pulse hard, full, frequent, and vibrating. The most vigorous course was adopted; two other students were called in to assist Stabb and myself, and every means used to give effect to the prescribed treatment. "As for Mademoiselle de Coigny, she remained in the sitting-room, the picture of intense anguish. I urged her to retire, but she shook her head. I now begged her to tell me what had caused this strange attack, but she was silent. At length I went and called Madame Lecomte--you recollect what a kind-hearted creature she was--and told her briefly the little I knew of the unfortunate girl. She answered the summons at once, and in the most gentle manner endeavored to persuade Mademoiselle de Coigny to go with her. It was in vain. She would not leave the room. Occasionally, through the day, she would step to Dervilly's bedside, and in the softest, sweetest, gentlest tone I ever heard, say, 'Alfred.' The effect was always the same as at first--exciting the poor fellow to still deeper paroxysms, and more violent exclamations. On the fourth day he died; the symptoms becoming more and more aggravating, until _coma_ supervened to delirium. During the whole period of his sickness Mademoiselle de Coigny never left the house--scarcely the room--Madame Lecomte on two or three occasions almost forcing the wretched girl away to her own apartments. When poor Dervilly sunk into that deep lethargic slumber, so much dreaded by the physician, because so fatal, she came almost joyfully into his chamber, and threw her arms tenderly around him, 'He sleeps at last,' she said, 'is it not well?'
