CHAPTER V
Palæontological and Biological Arguments |
73 |
The views of twenty specialists on the land-bridges. Late age of the Atlantic. Evidence of earthworms. Reptiles and mammals of both sides of the North Atlantic. Carboniferous fauna. Examples of other affinities. Faunal and floral affinities of both sides of the South Atlantic. Juan Fernandez. Hawaian Islands. Lemuria. The three components of the Australian fauna.
CHAPTER VI
Palæoclimatic Arguments |
90 |
Organic evidences of climate. Inorganic evidences of climate. Spitsbergen as an example of an alteration from a tropical to a polar climate. Alteration of the climate of Central Africa from polar to tropical. The hypothesis of the wandering of the poles. Former attempts to verify the hypothesis of the wandering of the poles. Inexplicability of the Permo-Carboniferous glacial phenomena. Solved by the displacement theory. Ice, Glossopteris flora, coals, rock-salt as evidence of climate in the Permo-Carboniferous. Provisional position of the poles for the periods after the Carboniferous and up to the present day. The Quaternary glaciation of North America and Northern Europe.

The absolute duration of the geological periods. The amounts of the annual displacements to be expected. The increase of the distance between Greenland and Europe. The question of the variation of the difference of longitude between Europe and North America. The secular alteration of latitude of the European and North American observatories.
