the Sand, Chalk, Earth, and the reft ; 

 or in the perpendicular Intervals of the 

 Strata of Stone, Marble, or other fp-

 on the faid Metalhck and Mineral Bo- 

 dies, (which are the Subjefls of the 

 feco?2d Sedion, ) I have not founded 

 any thing but what purely and imme- 

 diately concerns the Natural Hiftory 

 of thofe Bodies. 



To proceed therefore to the Account 

 of my Obfervations upon Sand-ftone. 

 And in thefej though I do not negleO: 

 to note the leveral Kinds or Varieties 

 of it : Free-ftone, Ragg-ftone, Lime- 

 ftone, and the reft : the different Hard- 

 nefs; or Solidity, of each: as alfo its 

 Colour, Texture, and the peculiar 

 matter which conftitutes it : yet I con- 

 fine my felf more ftriftly to confider 

 the manner how 'tis difpofed in the 

 Earth: the Strata ^ into which, by
