ctede that tile height of the mercurial column, if the barometers s 

 had been properly conftruded, would have been about 22 French 

 inches =23, 44 Englifh, and as the temperature was remarkably 

 cold this would indicate a height of about 8200 feet above the 

 level of the fea. 



But, fecondly, let the height be what it may, it is certain that 

 thefe fhells were depofitcd there after the emerfion cf land from 

 the primitive ocean, and confequently by a fubfequent deluge; 

 for Don Ulloa exprefsly tells us, that in the fame rocks in which 

 thefe fhells are found, petrified wood is alfo found, Mem. Phi- 

 lofophiques, p. 372. This wood muft have grown on dry landj 

 and muft have been floated when the fhells were depofited, 

 fmce both are found in the fame rocks. It muft have been 

 brought thither by a deluge, as no wood can at prefent grow 

 there, as Don Ulloa alfo attefts. The ftiells are for the moft 

 part bivalves, which geologifts allow to form petrifadtions of the 

 mof]i modern date. 



Lastly, La Peyroufe mentions that he difcovered marine 

 fhells on Mount Perdu, the-higheft of the Pyrenees, at the height 

 of nearly io,odo feet. How he afcertained the height is not 

 mentioned ; but that thefe fhells were depofited by the deluge is 

 certain, for at the fame height he found alfo the bones of land 

 animals petrified, 37 Journ. des Mines, p. 59, 60 and 64.
