Having examined forae of the Quarries 

 which furnifh volcanic ftones, I proceeded 

 to vifit thofe where carbonate of Ume is 

 dug, of which ftone there is no fcarcity in 

 the Euganean mountains. Such are the 

 quarries of BattagHa, Fraflinelle, and Saint 

 James, fituated on the dechvities of the 

 Monte Grande, above Teolo. Before we 

 reach the lava of Battagiia, we meet with 

 this carbonate. It is fcifTile, and eafily di- 

 vides in flakes, for the mofi: part, horizontal. 

 This quarry is very large, and in fome 

 places forty-five or fifty feet deep. It prin- 

 cipally confifts of this ftone, which is excel- 

 lent for making lime. The lime-ftone is 

 difpofed in ftrata of different thicknefs ; 

 from thofe of one inch or lefs to thofe of a 

 foot. We feldom meet with ftony ftrata 

 which preferve fo well their parallelifm to 

 each other, and to the horizon. In the 

 midft of the carbonates are found numerous 

 flints, or fire-ftones, already well known 

 from the mention made of them by other 

 writers; for the Euganean mountains,where- 

 ever they afford calcareous carbonates, ccrti-
