tology, or the science which treats of the fossil remains of the 

 ancient inhabitants of the globe, as shall enable the reader fully 

 to comprehend the nature of the principal discoveries in modern 

 geology, and the method of investigating natural phenomena, 

 by which such highly interesting and unexpected results have 

 been obtained." 



" Secondly, to assist the collector in his search for organic 

 remains, direct attention to those objects which possess the high- 

 est interest, and are especially deserving of accurate examination, 

 instruct him in the art of developing and preserving the speci- 

 mens he may discover, and point out the means to be pursued 

 for ascertaining their nature and their relation to existing animals 

 and plants." 



" Thirdly, to place before the student a familiar exposition of

 structure of vegetable and animal organization ; excite in his 

 mind a desire for further information, and prepare him for the

 as occasion may require. It must be swallowed — that is, read, 

 but not curiously, by him who would form and understand a< 

 collection of organic remains ; but by the student who would 

 profit by it to the utmost, it must be diligently studied and digest-

 and transported masses, and thus the labor will be rendered both
