 in the advocacy of Playfair, than was Moro in numbering 



it his admirers Cirillo Generelli, who, nine years 



among 



afterwards, delivered at a sitting 



Academicia 



mona a 



spirited exposition of his theory. 



This learned 

 Carmelitan friar does not pretend to have been an original 

 observer, but he had studied sufficiently to enable him to 

 confirm the opinions of Moro by arguments from other 

 writers ; and his selection of the doctrines then best estab- 

 lished is so judicious, that a brief abstract of them cannot 

 fail to be acceptable, as illustrating the state of geology in 

 Europe, and in Italy in particular, before the middle of the 



last century. 



The bowels of the earth, says he, have carefully preserved 



the memorials of past events, and this truth the marine 

 productions so frequent in the hills attest. From the reflec- 

 tions of Lazzaro Moro, we may assure ourselves that these 

 are the effects of earthquakes in past times, which have 

 changed vast spaces of sea into terra firma, and inhabited 

 lands into seas. In this, more than in any other department 

 of physics, are observations anc
