[HORLOGERIE], DELAMBRE, Extrait d'un rapport sur un ouvrage de M. Janvier, 1813

First edition.
Rare booklet probably published by Antide Janvier in which he reproduces the minutes of a session of the Academy of Sciences in which Delambre acts as rapporteur for the reading of his work: "Revolutions of the Celestial Bodies by the Mechanism of the Cogs ". Janvier adds some comments in footnotes in which we sense his bitterness that the Institute did not judge his book worthy of being sent to universities for study. He is saddened that they preferred to give four thousand francs to the miller Girardot for his uranographic machine. Janvier was one of the most brilliant watchmakers of his time, famous in particular for his spheres and planetaries.
