Note 73 — Chapter VIII · LAMARCK’S WORK IN GEOLOGY

J. G. Lehmann of Berlin, in 1756, first formally stated that there was some regular succession in the strata, his observations being based on profiles of the Hartz and the Erzgebirge. He proposed the names Zechstein, Kupferschiefer, rothes Todtliegendes, which still linger in German treatises. G. C. Fuchsel (1762) wrote on the stratigraphy of the coal measures, the Permian and the later systems in Thuringia. (Zittel.)
