 be drawn from them.. We have here the ma-

 this fragment of rock from its native place, di- 

 ilant at leaft feveral hundred yards from its pre- 

 fent lituation, place it upright on its edge, en- 

 compafs it with a folid rock, of a nature quite 

 heterogeneous to itfelf, and bellow on it, at the 

 '°'™E fame time, a great addition of folidity and in-

 wadiii; now imbedded, be fuppofed to have been once 



«¥(i ri: in fulion, and forcibly thrown up from below, 

 2d,m invading the ftrata, and carrying the fragments 



along with it, the whole phenomena now de- 

 jj^gl? fcribed admit of an explanation, and all the cir- 

 cumftances accord perfectly with one another ; 

 but, without this fuppofition, they are fo many 

 feparate prodigies, which have no connediion 

 with one another, nor with any thing that is
