Plein veau de l'époque, dos à cinq nerfs orné et doé. Un volume in quarto (250x197 mm), (8)-lxiv-660 pages et 15 planches dépliantes. Coins émoussés. Premier mors fendu sur quelques centimètres. Première édition en français et surtout édition originale des importantes tables sur le mouvement de la lune calculées par Flamsteed et les ajouts de Le Monnier. L'ouvrage est agrémenté de 2 cartes zodiacales, 3 cartes des cratères lunaires, 1 plan du système solaires, et 9 planches géométriques (numérotées de I à IX).
