8vo. P. [i], half-title, verso blank; p. [iii], title, verso blank; pp. [1]-4, “Avis au Lecteur”; p. [5], “Avant Propos,” verso blank; pp. [7]-71, text; p. [72], blank. Copies: HEH, NYP, YU. Sabin #95793. Sixième Edition, with identical title (except for change in number of edition), identical imprint and date; the text is set largely from the same type but extended by new matter to p. 76, and there is no blank page at the end. The Cinquième Edition described above may be safely regarded as the _editio princeps_; there were, however, at least three variant issues, two of which are easily confused with the original edition. One of these corresponds exactly in imprint, pagination, and signatures with the regular Cinquième Edition but is set from different type, has a different title-page border, and uses less elaborate printer’s ornaments throughout; it may be at once distinguished from the original by the fact that the words “Monsieur de Sartine” in the title are printed, not in red as in the original, but in black; copies in BA, NYP. A second variant has the same imprint as the regular Cinquième Edition, but the title-page has a still different border, no rubrication, and the word “Cinquième” is erroneously printed with an acute instead of a grave accent; the pagination is the same as that of the regular Cinquième Edition, but the variant is a smaller octavo, the type is not the same, nor are the signatures (regular: []², B-K⁴; variant: []², B-E⁸, F⁴); copies in NYP, YU. There is, finally, in the Yale University Library an issue called the “Cinquieme [_sic_] édition,” with a title-page border different from any in the preceding issues, with the same pagination as the regular Cinquième Edition, but from different type, with signatures[]¹, B⁸, C-I⁴ (half-title doubtless wanting), and with the puzzling date “M. DCC. LXXXII.” _La Cassette verte_ is a political and bibliographical hoax. The text purports to be secret papers found in a dispatch-box belonging to M. de Sartine, French Minister of Marine. (On Mademoiselle Du Thé, i.e., Rosalie Duthé, a Parisian courtesan who had recently visited England, see Pierre Larousse, _Grand dictionnaire ... du XIXᵉ siècle_, Paris, 1866-90, VI, 1447-1448.) The papers expose the motives of the French government in aiding the United States and satirize Franklin’s activities in Paris, English sympathizers with the American cause, and the like. A letter supposedly written by one of Sartine’s agents in London provides a gloss on certain passages in _Anticipation_. I quote from the English version (no. vi, below):
