SUCCESSION OF ANIMALS AND PLANTS. 141 



botanical characters of these remains are not remarkable 

 for the accuracy and for the ingenuity with which they 

 have been traced. On the contrary, having myself thus 

 far devoted the better part of my life to the investigation 

 of fossil remains, I have learned early, from the difficulties 

 inherent in the subject, better to appreciate the. wonder- 

 ful skill, the high intellectual powers, the vast erudition, 

 displayed in the investigations of Cuvier and his succes- 

 sors upon the faunce and florae of past ages. 1 But I can- 

 not refrain from expressing my wonder at the puerility 

 of the discussions in which some geologists still allow 

 themselves to indulge, in the face of such a vast amount 

 of well digested facts as our science now possesses. They 

 have hardly yet learned to see that there exists a definite 

 order in the succession of these innumerable extinct 

 beings ; and of the relations of this gradation to the other
