 Montes fecundarios y the large calcareous hills, di- 

 vided into ftrata, confiding of a compact impal- 

 pable limeftone, and containing petrified marine 

 bodies j fuch are part of the Alps, or the large 

 chain of mountains that feparate Germany from 

 Italy; Montes tertiarios^ or colles, he calls the 

 lower hills, which confift likewife of fmall lime- 

 ftone beds filled with petrifactions, or now and 

 then confift of fand and clay-beds, but are of a 

 later origin, fmce incumbent on the Montes fecun- 

 darios, and produced by their decays varioufly 

 \vafhed down and accumulated together. Add to 

 thefe the volcanic hills, or their remains and old 

 devaftations. Remember what I faid to you

 tions came from beneath the flate, or from a ft ill

 way through the Montes fecu/idarios and tertiarios. 



And now permit me to entertain you by a par- 

 ticular account of each of thefe four different 

 fpecies of mountains, which are found in the 

 Vieentine and Veronefe territories.
