8 OBJECTS OF THE SOCIETY. 



clay, gravel, or sand, in which they were found, distinctly 

 noted— a precaution upon which their value almost entirely 

 depends — and will send them to the Society, accompanied by 

 any remarks which may occur, on the position of the bed, 

 and the character of other beds lying above or below it, he 

 will confer a favour on the Institution, and contribute 

 materially to the advancement of knowledge. 



Proprietors of land, whose enlightened views have led them 

 to procure geological surveys of their estates, may greatly 

 benefit the cause of Science, by communicating documents 

 relative to the portions of the Strata thus examined; and the 

 Society is anxious to invite the correspondence both of 

 Surveyors and of Miners, and to obtain the assistance which 

 they are so capable of lending to its objects ; par- 

 ticularly by noticing those points of junction, where 

 different kinds of rock or other beds come in contact with 

 each other, and by furnishing Sections of the Strata, as 

 they are laid open, in some parts, naturally by rivers or the 

 sea, and, in others, presented artificially by quarries, wells, 

 or mines. 



These indeed are minute details ; but with such minutiae 

 great practical utility is both immediately and remotely 

 connected :from such minutiee the knowledge of the Earth's 

 structure is to be deduced, and a Science hereafter to be raised, 

 which may lead to conclusions as important, perhaps, as any of 

 those which have been so happily derived from the other parts 

 of Natural Philosophy.
