In the great volume of nature, we see its effects, 

 which appear to be scattered over every region, or 

 habitable portion of the globe ; and we are left free, 

 to contemplate and trace them to their cause. 



These effects, so multiplied and various, so ob- 

 viously plain and intelligible, inform us in a language 

 that cannot be misunderstood, that in America, they 

 were produced by currents which flowed across the 

 continent from north to south ; and in Asia and a part 

 of Europe, from south to north. 



To these facts, the attention of the philosopher and 

 the votaries of science are earnestly invited. 



The interest which they are calculated to excite, 

 will richly compensate for the trouble of an investiga- 

 tion ; independently of the sublime emotions which 

 the numerous and diversified objects of fossil organick 

 remains, those " medals of creation" are calculated 

 to inspire. 



But this is not all. By an attentive examination of 

 these facts, we shall, not only aid and assist in the 

 great work,* so happily begun and advancing, but be 

 enabled to trace up, in successive gradations, and to 

 comprehend the various physical changes that have 

 taken place, since this earth has been rendered the fit 

 habitation of organized beings. 



To attain this point, we may be considered as 

 having arrived at the ne plus ultra of human sagacity 

 and penetration, as it respects the science of geology.
