ITALY. LETTER II. 1J 



The Paduan-hilh, which lie free and ifolated, 

 and are known under the name of Monies Euganei^ 

 confift of lavas of ancient extinct volcanos, ne- 

 ver mentioned by any hiftorian. Thefe lavas are 

 of a red, black, grey, and whitim colour, and 

 commonly contain a great number of white cryf- 

 talline garnets, and black fherl-nodules. Being 

 very common and hard, they are, together with the 

 broken bafalt-columns, employed in the pavement 

 of almoft every flreet at Padua and Venice. In 

 one of my next Letters I mall fpeak of them more 

 particularly. Befides thefe ifolated volcanic hills, 

 the calcareous Alps run through the Paduan ter- 

 ritories. 



/ Bagni tfAlbano, defcribed in the above treatife 

 of Mr. Vanaeili) are about twenty miles diftant 

 from Padua. An Englimman, Sir John Strange, 

 who, on account of his health, has lived in this 

 country for feveral years, has exactly examined all 

 thefe parts *, arid written a defcription of the fof- 

 fils and lavas found thereabouts and in the Euga- 

 nean hills, which, together with that collection^ 

 he has defigned for the Paduan cabinet of natural 

 hiftory. 



* His account of two giants-caufevvays, or groups of prif- 

 inatic bafaltine columns, and other vulcanic concretions in 

 the Venetian Hate in Italy, together with two engravings of 

 Monte Kofi and il Monte di Diavoto, was prefented to the Royal 

 Society in 1774, and is inferted in Phil Tranfaa. vol. lxv 

 part i. for 1775,
