feet, Lafius, 148; and Renovants, p. 76, afferts that none of 

 thofe of Siberia on each fide of the Altai exceed two thoufand 

 Paris feet. Nay Pallas does not allow to calcareous mountains 

 that contain petrifadions (which on this account he judges to 

 be formed in the fea) above thirteen or fourteen hundred feet, 

 I Ad. Petrop. 59, but a view of the mountains of Switzer- 

 land fhews that many of them are much higher. 



The neareft approach I have met with, to the limits I have 

 afllgned to the height of the antient ocean when it began to 

 be peopled with fifh, is an obfervation of Mr. De Luc's, that 

 he found cornua ammonis petrified on mount Grenier, whofe 

 height is feven thoufand eight hundred feet, 2d Lettres a k 

 Reine, 227 ; and another of Baron Zoits on the mountain of 

 Terglore in Carniola, that petrifadions were found in limeftone 

 at the height of between thirteen and fourteen hundred German 

 lachters, taking fuch to be equal to thofe of the Hartz, the height 

 was eight thoufand five hundred Englifh feet nearly, and 

 hence I have extended the limits to eight thoufand five hundred 

 feet, yet it does not appear by Mr. De Luc's relation that thefc 

 petrifadions were imbodied in the (lone or rock which con- 

 ftitutes the mountain, and therefore may well be only relics 

 of the deluge. He alfo fays that the chain of Jura abounds in 

 marine remains, but Jura confifts of two chains, the higheft 

 of which confifts of primaeval limeftone in which no petri- 

 fadions are found, and this is the higheft, 30 Roz. 275, but the
