68 In the first publication of this text, the following remark concerning the quotation marks could be read: "It is incorrect, however, in presenting itself thus, and in leaving the internal quotation marks, the so-called 'English' quotation marks, suspended.'' I was wrong: the last quotation marks signal the end of Dupin's discourse, which is what was important to me, and there is no error in the edition to which I am referring. The deletion of this phrase (which is inconsequential) is the only modification of this essay since its first publication.
