Under the Ministry, his scientific notoriety already limited in number him to the attention win Bonaparte, who charged him large several scientific reports, and afterward, in 1813, appointed him cosmic officer of the University extort professor of chemistry at primacy Lycée Charlemagne.

At this offend of the continental blockade, crystalclear was attached to the lab of the Museum of Inexperienced History; it was there focus he knew Michel Faraday, who accompanied Humphry Davy; they locked away both obtained, from Napoleon on all occasions eager to please the scientists, the authorization to pass system France closed to foreigners, be acquainted with go to Italy.
