confiit of comnion bafaitine, or other lava, like thofe of 
Aavergae, Velay, and the Vicentine and Veronefe terri- 
tories; yot fome there are, and very curious, which I 
fhill briefly defcribe. Monte Nuovo, or the New Moun- 
tain, about a league to the fouth of Abano, and near Bat- 
taglia, is one of them. Though connedfedwith the prin- 
cipal chain of the Euganean hills, by a depreifed neck, or 
ijfhmus, yet it contains no granite, or lime-ftone, like the 
reft of that chain, but is formed exclufively of lava, of 
various kinds, and different from any lava I obferved 
about thefe hills. Great part of its Rtrface, efpedally 
about the top, is very rough, knotty, and fiiiuous, and 
manifeftly appears to have concreted from a fulion by 
hre. The fkirts and bottoms of it equally prove the fame, 
-confift ing moftly of another fort of mixed and congealed 
lava, which the Italians call lava brecciata, from its re- 
femblance to the Breccia marbles. It is formed by many 
broken and irregular fragments, that have been acci- 
dentally licked up, as- it were, or colleded by the lava, 
while melted and running, and concreted with it, with- 
out however fuffering fulion. Large broken maffes of 
this lava are feen about the foot of the hill, very much 
refembling fragments of ancient Roman buildings ruin*^ 
ed ; infomuch, that I miftook for fuch the firft mafs I 
faw, under a part of the hill, called II Monte della Croce, 
from the church built upon it. The manner in which 
the Romans were accuftomed to fill up the inner parts 
of their thick walls, within the facings, exa6tly refem- 
hles this kind of Breccia lava\ fince they ufed irregular
