It is true Werner was not so well versed in comparative 
anatomy as M. Cuvier, who in this branch surpasses all his 
predecessors, — Attar his contemporaries also; yet I 
will venture to to M. Cuvier, that it appears to me he is 
not ssipneiniod witht the merits of Werner in contributing to 
the promotion of the natural history of organic remains, 
om confining hi to the mere science of mineralo- 
gy, in forming his theory of the earth, Werner from the first 
occupied himself with the study of the different relations of 
all the classes of organic remains. A genius like his must 
naturally have pork = that a complete know. t 
relations was absolutely necessary to a geologist, and ac- 
cordingly, with such a conviction, he informed himself of 
all that was known of petrifactions. During his lectures, he 
often called the attention of his auditors to the importance 
of forming collections, which besides a complete series of 
rocks and minerals, to illustrate the formation of our globe, 
he insisted, ought also to embrace an extensive collection of 
organic remains, both of vegetables and animals. Neitler 
did he neglect, at the same time, to make mention of the nu- 
merous researches and discoveries, relating to those caverns 
which contained large quantities of animal remains. * 
Werner also insisted much upon the observation, made, if 
I mistake not, by M. Lister, more than one hundred and fifty 
years ago, that the different formations were capable of be- 
mg distinguished by means of the fossil remains they con-
