bits of ftone, confufedly thrown into, and cemented with 
a large body of mortar. This kind of lava is common 
enough about Vefuvius, and other recent volcanos; and 
alfo occupies large tra6ts in Upper Auvergne, efpecially 
between Murat and Aurillac ; where it covers the Ikirts 
of the hills, by the fide of a valley, for many miles ; form- 
ing the moft grotefque figures imaginable. I have alfo 
obferved it, in plenty, in the environs of Puy, in Velay. 
The famous St. Michael’s church at Puy is built on the 
fummit of a high, ifolated, and almofi: pointed rock of 
this lava^ and makes a very extraordinary appearance. 
Monte Nuovo feems to have fuffered a more recent con- 
flagration than any other of the Euganean hills, as its 
name rather implies. But though its fkirts and furface 
appear, almofi: every where, to have fuffered a fufion ; 
yet parts of the internal firu6ture of the mountain,- ma- 
nifeft, however, the primary horizontal direction and pa- 
rallelifm of the Jlrata^ as I before remarked of the Vero- 
nefe vulcanic hills. This I particularly obferved within 
the park of Cataio palace, which is fituated at the north- 
eafi: extremity of Monte Nuovo, and has parts of its un- 
der apartments cut out. of. the folid rock of lava> Sup- 
pofing Monte Nuovo ifolated from the low narrow ifth- 
mus before mentioned, it.would meafure about fix miles 
in circumference at the bafe. Ifliall further obferve, that 
it forms a fort of half moon, on the weft fide of the plain 
near Battaglia,, and ftands in the centre of feverai hot 
fprings; as thofe of St. Elena, and San Bartolomeo, to the 
fouth and weft ; thofe of Abano and Monte .Ortone to the 
north.
