On two 17th century dispute by naturalists
The article discusses two disputes held by naturalists in the 17th century. In the first dispute Jan Amos Komensky attacked the Cartesian doctrine of compression and decompression of air. In the second, the Jesuit, Wojciech Tylkowski, challenged the then prevalent theories of the origin of amber, according to which amber was being created continuously from "earth oil", which was supposed to be flowing to the surface of the earth. Following Pliny, Tylkowski assumed that amber had been formed from the resin of coni-ferous trees, subsequently submerged by the Baltic Sea.
