Lacépède continued the part of the "Histoire Naturelle" which dealt with animals. A few months before Buffon's death, en 1788, Lacépède published, as a continuation, the first volume of his "Histoire des Reptiles", on egg-laying quadrupeds. The next year, he wrote a second volume on snakes, published during the French Revolution. Between 1798 and 1803, he brought out the volume "Histoire des Poissons". Lacépède made use of the notes and collections left by Philibert Commerson (1727–1773). He wrote "Histoire des Cétacés" which was printed in 1804. At that point, the "Histoire Naturelle", by Buffon and Lacépède, thus contained 44 quarto volumes forming the definitive edition. Another edition in quarto format was printed by the "Imprimerie royale" in 36 volumes (1774–1804). It consisted of 28 volumes par Buffon, and 8 volumes by Lacépède. The part containing anatomical articles by Louis Jean-Marie Daubenton was dropped. The supplements were merged into the relevant articles in the main volumes. The "Imprimerie royale" also published two editions of the "Histoire Naturelle" in duodecimo format (1752–1805), occupying 90 or 71 volumes, depending on whether or not they included the part on anatomy. In this print format, the original work by Buffon occupied 73 volumes with the part on anatomy, or 54 volumes without the part on anatomy. The continuation by Lacépède took up 17 duodecimo volumes. A de luxe edition of "Histoire Naturelle des Oiseaux" (Birds) (1771–1786) was produced by the "Imprimerie royale" in 10 folio and quarto volumes, with 1008 engraved and hand-coloured plates, executed under Buffon's personal supervision by Edme-Louis Daubenton, cousin and brother-in-law of Buffon's principal collaborator. The "Histoire Naturelle" was translated into languages including English, German, Swedish, Russian and Italian. Many translations, often partial (single volumes, or all volumes to a certain date), abridged, reprinted in the same translation by different printers, or with additional text (for example on insects) and new illustrations, were made at the end of the eighteenth century and the start of the nineteenth century, presenting a complicated publication history.
