[100] The following statement of Cuvier's views is taken from Jameson's translation of the first _Essay on the Theory of the Earth_, "which formed the introduction to his _Recherches sur les Ossemens fossiles_," the first edition of which appeared in 1812, or ten years after the publication of the _Hydrogéologie_. The original I have not seen, but I have compared Jameson's translation with the sixth edition of the _Discours_ (1820). [101] Cuvier, in speaking of these revolutions, "which have changed the surface of our earth," correctly reasons that they must have excited a more powerful action upon terrestrial quadrupeds than upon marine animals. "As these revolutions," he says, "have consisted chiefly in changes of the bed of the sea, and as the waters must have destroyed all the quadrupeds which they reached if their irruption over the land was general, they must have destroyed the entire class, or, if confined only to certain continents at one time, they must have destroyed at least all the species inhabiting these continents, without having the same effect upon the marine animals. On the other hand, millions of aquatic animals may have been left quite dry, or buried in newly formed strata or thrown violently on the coasts, while their races may have been still preserved in more peaceful parts of the sea, whence they might again propagate and spread after the agitation of the water had ceased."

Clark, from 14th Annual Report New York State Geologist, 1895, pp. 127-217 (p. 16). Bernard gives no reference to the work in which Schlotheim expressed this opinion. E. v. Schlotheim's first work, _Flora der Vorwelt_, appeared in 1804, entitled _Beschreibung merkwürdiger Kraüterabdrücke und Pflanzenversteinerungen. Ein Beytrag zur Flora der Vorvelt._ I Abtheil. Mit 14 Kpfrn. 4^o. Gotha, 1804. A later work was _Beyträge zur Naturgeschichte der Versteinerungen in geognostischer Hinsicht_ (_Denkschrift d. k. Academie d. Wissenschaften zu München für den Jahren 1816 und 1817_. 8 Taf. München, 1819). He was followed in Germany by Sternberg (_Versuch einer geognostischbotanischen Darstellung der Flora der Vorvelt._ 1-8. 1811. Leipzig, 1820-38); and in France by A. T. Brongniart, 1801-1876 (_Histoire des Végétaux fossiles_, 1828). These were the pioneers in palæophytology. [104] Bernard's _History and Methods of Paleontological Discovery_ (1879), p. 23.
