The format of this tiny book is described as "in-128" in the "Catalogue de la bibliotheque de M. le Comte Charles de l'Escalopier" (1866), no. 513. This seems accurate if the original sheet of paper was 18" x 23." Such a sheet folded six times would produce a Medium 64mo of 128 pages, each measuring approximately 2 7/8" x 2 1/4" -- or about twice the size as the present "volume" (if one could describe it as such). The diminuitive such is such that it is surprising that more copies didn't get lost or accidentally discarded -- or perhaps even swallowed -- over the last 282 years. Arthur A. Houghton Jr. had a copy (his sale, Christie's NY, Dec. 5, 1979, lot 81) along with the 1733 issue published by J. Francois Herissant. The present edition is a reissue of the Herissant's sheets with a different imprint. We challenge anyone to collate them (hint: A-M8. This is not a chess move).
