 credences of which I speak have never the full force of thought—such sentiments are seldom thoroughly stifled unless by reference to the doctrine of chance, or, as it is technically termed, the Calculus of Probabilities. Now this Calculus is, in its essence, purely mathematical; and thus we have the anomaly of the most rigidly exact in science applied to the shadow and spirituality of the most intangible in speculation.

The extraordinary details which I am now called upon to make public, will be found to form, as regards sequence of time, the primary branch of a series of scarcely intelligible coincidences, whose secondary or concluding branch will be recognized by all readers in the late murder of Mary Cecila Rogers, at New York.

When, in an article entitled "The Murders in the Rue Morgue," I endeavored, about a year ago, to depict some very remarkable features in the mental character of my friend, the Chevalier C. Auguste Dupin, it did not occur to me that I should ever resume the subject. This depicting of character constituted my design; and this design was thoroughly fulfilled in the wild train of circumstances brought to instance Dupin's idiosyncrasy. I might have adduced other examples, but I should have proven no more. Late events, however, in their surprising development, have startled me into some farther details, which will carry with them the air of extorted confession. Hearing what I have lately heard, it would be indeed strange should I remain silent in regard to what I both heard and saw so long ago.

Upon the winding up of the tragedy involved in the deaths of Madame L'Espanaye and her daughter, the Chevalier dismissed the affair at once from his attention, and relapsed into his old habits of moody reverie. Prone, at all times, to abstraction, I readily fell in with his humor; and, continuing to occupy our afforded. Thus much escaped the writer of which he could have availed himself had he been upon the spot, and visited the localities. It may not be improper to record, nevertheless, that the confessions of two persons, (one of them the Madame Deluc of the narrative) made, at different periods, long subsequent to the publication, confirmed, in full, not only the general conclusion, but absolutely all the chief hypothetical details by which that conclusion was attained.
