in coal beds and carbonaceous rocks. He said the first one to pour out this was Tyndall in 1861 before the British Association. Later the idea was carried out more by Arrhenius Freck thinks the idea of carbon dioxide absorbs rather underestimates than over estimates. Coal pours [illegible] about the carbon dioxide and a lot of temperature falls. The new supply he thinks came from the volcanoes, in the periods of just volcanic activity fuse in with the cold times. He pointed out the vast Jurassic vulcanology of the west coast of U.S.A. refill the air as warming again during Jurassic times. The great Tertiary vulcanology to refill the Cretaceous bios and the recent vulcanology to refill the Quaternary loss. The land movements he thought inadequate cut away this off the close of the Paleozoic. The just CO2 absorption by the carbonaceous rocks was the primary cause. The just climatic changes also the cause for the just change in animal life.
