Thanks "Mr le Conseiller d'Etat Fuss" for the honnor to work with the Academie Imperiale. Burckhardt regrets that the years from 1806 to 1807 have not favoured astronomic observation, also due to his illness that was lasting several month. Burckhardt answers to Fuss' request by noting a lunar eclipse observed by Bouvard and sends an entrance ticket, so that Fuss could take part in the next campaign of Wisniewski: "La lettre dont Vous m'avez honorée m'a fait bien du plaisir & je serais infiniment flatté de contribuer, tant soit peu, à la grande & belle entreprise de l'Academie Imperiale.
