Paris, Firmin Didot, 1795 (Tirage /issue of)1846.), in-4 (23,5 x 15,5 cm. or 9.25 x 6.10 inches), vi - 118 pp. - 680 pp., contemporary half black calf (some wears), flat spine nicely gilt tooled, sprinkled edges.
Stereotype edition, engraved, melted and printed by Firmin Didot. "After the Estienne family, the one the French imprimery can take pride is indisputably the Didot family, to which one owes the majority of the improvements obtained, lately, in the processes of the typography. Firmin Didot, born in Paris, in 1764, second wire of François-Ambroise Didot, makes his a famous name as literary man, printer, engraver and letter-founder, and as paper manufacturer. In 1789, he succeeded his father in the foundry which he enriched by elegant types. He invented, in 1795, a process of stereotyping, applied to the Tables of logarithms of Callet. At the exibition of the manufacturing products of 1798, he presented stereotype editions done with his new manufacturing process". (Paul Dupont, Didot, 1853). Good edition given by the French mathematician Jean-François Callet (Versailles 1744 - 1798) of these tables of Gardiner, also called tables of logarithms. One of the most complete and pratically useful collections of logarithms published, and peculiar in giving a centisimally divided canon" (J.W. L. Glaisher, F.R.S.). Little split in the bottom of one gathering. Otherwise nice copy. Cfr. Henry Sotheran 667 (autre édition) ; Graesse t. 2 , p. 17
