However, it is infifSed that petrified fhells have been found at 

 a far fuperior height to that which I flated as the highefl limit 

 at which they could be found, namely 9000 feet, for that thofe 

 which I quoted as proofs of a fubfequent deluge, found, accord- 

 ing to Don UUoa, at the height of 14,220 feet in Peru, were in 

 reality petrified. To this account, as it was only a hearfay report 

 of Gentil, who had it from Don Uiloa, 1 own 1 did not give full 

 credit, at leafl I thought the circumftance of their having been 

 petrified and imbodied in a rock not probable ; fince that time 

 I have met with a work, compofed by Don Ulloa himfelf, intitled 

 Memolres Philofophiqiies, Hifioriques Sif Phyfiques, in the firfl vol of 

 which, p. 3+ and 364, the fad of the fhells being petrified and 

 imbodied in a rock is fully dated and confirmed ; but I fliall 

 here fatisfaclorily prove that the height at which they were found 

 did not exceed, nor even equal 9000 feet above the level of the 

 fea. And, fecondly, that they were left there by a deluge that 

 fucceeded the emerfion of land from the primseval ocean. 



I**. Gentil tells us, Mem. Par. 1771, p. 459 in 8vo. that thefe 

 fliells were found on a mountain near Guancavelica, a fmall 

 town or village between 12" and 13° fouth latitude, which 

 mountain he fays is far from being one of the highefl of the 

 Cordeliercs, and that on the fpoc in which the fhells were found 

 the mercury in the barometer flood at the height of 17 inches, one 

 line and ^=17, 103 inches, from which he infers that this fpot vas 

 elevated 220o| toifes over the level of the fea, = 13,869 Englifh 

 feet. This height 1 fhall now fhew to have been falfely el^imated.
