(2) Does not believe in any wide spread Tertiary and Biguaran seas. In the former he says there are several emergences and submergences. He has now come to the view that the changes of faunas seen in continuous sections are a series of migrations (submergences) broken by times of non deposition (emergences). He therefore now holds that there are far more emergences than one thinks for and further that it is but nearly that the orities of the four oceanic sides were connected and eremingly. For instance while the Louisville deposits are forming then in arctic invasion and when the latter sea is at hand then there is ar Gulf invasion. In other words land oceans sea, are alternate elevation of one and then the other end if the continents. (3) Does not believe in Chamberlins Cosmo- portitan faunas, Repressive and Expanding Evolution in times of wide spread continental seas, emergences and submergences.
