HUTTONIAN THEORY. 221 



But this appearance of fuccefs vanifnes, when 

 , the elevation and diflurbance of the ftrata are 



'1 more minutely examined, and are found to in- 

 ' elude waving and inflexion, in a great variety 

 l\ of forms. It then becomes evident, that the 



r 



beds of rock, at the time when they were di 



llurbed from their horizontal pofition, had 



M not their prefent hardnefs and rigidity, but 



were, in a certain degree at leaft, foft and flexi- 

 ble. Without thefe qualities, they could not 

 ^on have received, as they bave often done, the 

 i!ic; curvature of a circle, not many feet, nay, not 



many inches, in diameter ; nor could they have 

 alji been bent into fuperficies, with their curvature 

 atG in oppoiite directions, fo that the fame furface is 



I 



leia in one part convex, and in another concave, on 



m, the fame fide, with a line of contrary flexure in- 



lini, terpofed. Thefe are appearances, not reconci- 



^011: lable with the mere failing in, and breaking 



down of indurated rocks.

199. The inflexions and wavings that we are 

 here fpeaking of, though not peculiar to the 

 fjj primary fl:rata, are found mofl; frequently among 



them, and are perfeClly familiar to every one 

 who has travelled among mountains with any 

 view to the fliudy of geology. The following 

 are a few inftances of this phenomena, out of a 

 great number which might be produced.
