Following the Russian-Siberian journey, Humboldt intensively dealt with the geology and climatology of the Asian continent. A first result was an Academy lecture held in January 1831 in Paris, entitled “Sur quelques phénomènes physiques et géognostiques de l'Asie au nord de parallèle de 50 degrés” (<ref xmlns="http://www.tei-c.org/ns/1.0" target="http://kalliope-verbund.info/DE-611-HS-1035153">Papers Large Box 5</ref>), which will be published for the first time in the <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">edition humboldt digital</hi>. Here, too, Humboldt's research reveals itself to be a science on the move: “La description du globe n'est point une science stationnaire” [The physical description of the Earth is not a stationary science].
