 and at the bottom of the fea, they were broken, 

 fet on edge, and raifed to the furface. It is even 

 probable, as formerly obferved, that to this fuc- 

 ceeded a depreilion of the fame llrata, and a fe- 

 cond elevation, fo that they have twice vifited 

 the fuperior, and twice the inferior regions. 

 During the fecond immerlion, were formed, firft, 

 the great bodies of pudding-ftone, that in fo 

 many initances lie immediately above them ;

 llrata, and the confequent formation of the cry- 

 ftallized and unftratified rocks, namely, the gra- 

 nite, i^ietallic veins, and veins of porphyry and 



whinftone.
