The way Berthollet effectively directed the practical installation of the Institute at Qassim Bey's Palace in Caïro, cemented the friendship with Bonaparte in a way that proved its worth in the patronage of the Arcueil Society.
When Berthollet, in 1807, concluded that the arrangement for research facilities at Arcueil had cost him more than he could afford, Napoleon, alerted by Laplace and Monge, immediately lend him 150.000 francs to break even.
The informality of the "Institut d'Egypte" found its continuance at Arcueil where Berthollet from his Egyptian-decorated study remained in charge of the publication of the "Description de l'Egypte (1809)" (ref: Crosland, 1967).The quantitative applications of the new science of chemistry had important significance for the state economy.
Following Volta's visit to Paris in 1801 important work on the Voltaic pile, involving the Arcueil circle, was carried out under Bonaparte's auspices rewarding Paul Erman, Humphry Davy, Gay-Lussac and Louis Jacques Thenard in the process.
The enhancing of the quality of iron and steel, with Collet-Descotils -the precursor in the discovery of iridium- in charge as chief engineer at the "Ecole des Mines", and above all the development of gunpowder were of prime military significance.
In 1820 Dulong wrote to Berzelius: It was the testimony of a changing mood and when John Dalton, who had strong differences of opinion with the Society, visited Arcueil in 1822, he received a hearty welcome.
The Society of Arcueil however, through the younger generation, was still to illuminate such work as that of Liebig, Pasteur, Fresnel, Niepce, Daguerre, Léon Foucault ... as well as many others in the field of scientific education.
