The shutting of a door disturbed me, and, looking up, I found my cousin had departed from the chamber. But from the disordered chamber of my brain, had not, alas! departed, and would not be driven away, the white and ghastly _spectrum_ of the teeth. Not a speck upon their surface--not a shade on their enamel--not a line in their configuration--not an indenture in their edges--but what that brief period of her smile had sufficed to brand in upon my memory. I saw them _now_ even more unequivocally than I beheld them _then_. The teeth!--the teeth!--they were here, and there, and every where, and visibly, and palpably before me, long, narrow, and excessively white, with the pale lips writhing about them, as in the very moment of their first terrible development. Then came the full fury of my _monomania_, and I struggled in vain against its strange and irresistible influence. In the multiplied objects of the external world I had no thoughts but for the teeth. All other matters and all different interests became absorbed in their single contemplation. They--they alone were present to the mental eye, and they, in their sole individuality, became the essence of my mental life. I held them in every light--I turned them in every attitude. I surveyed their characteristics--I dwelt upon their peculiarities--I pondered upon their conformation--I mused upon the alteration in their nature--and shuddered as I assigned to them in imagination a sensitive and sentient power, and even when unassisted by the lips, a capability of moral expression. Of Mad'selle Sallé it has been said, "_que tous ses pas etaient des sentiments_," and of Berenice I more seriously believed _que tous ses dents etaient des idées_. And the evening closed in upon me thus--and then the darkness came, and tarried, and went--and the day again dawned--and the mists of a second night were now gathering around--and still I sat motionless in that solitary room, and still I sat buried in meditation, and still the _phantasma_ of the teeth maintained its terrible ascendancy as, with the most vivid and hideous distinctness, it floated about amid the changing lights and shadows of the chamber. At length there broke forcibly in upon my dreams a wild cry as of horror and dismay; and thereunto, after a pause, succeeded the sound of troubled voices intermingled with many low moanings of sorrow, or of pain. I arose hurriedly from my seat, and, throwing open one of the doors of the library, there stood out in the antechamber a servant maiden, all in tears, and she told me that Berenice was--no more. Seized with an epileptic fit she had fallen dead in the early morning, and now, at the closing in of the night, the grave was ready for its tenant, and all the preparations for the burial were completed.
