no granite mixed with the lava, in thefe lower limeftone 
Ikirts of the Alps, though it abounds fo much in the 
neighbouring Euganean hillsy^as well as in Auvergne 
and Velay, as I before obferved. Notwithftanding the 
general vulcanic charadler of this branch of Montebello, 
its original ftruaure and chara6ters are hill very evident, 
and perfectly correlpond with thole of the neighbouring 
branches, that have never fulfered fire. For though fome 
new igneous modifications have accidentally and partial- 
ly taken place about the Ikirts and furface of this branch; 
yet in other more internal parts, not only the original 
horizontal pofition and parallelifm of the Jirata are ma- 
nifefi:, but fmall, though integral parts of thofe Jirata, 
here and there, remain unburnt, and fliow their calca- 
reous qualities, ltru6ture, and extraneous contents, per- 
fectly fimilar to thofe of the other neighbouring moun- 
tains, that have never fuffered by fire. This I particu- 
larly obferved along the brows, or upper lateral Jirata of 
the vulcanic branch juft mentioned, above the valley be- 
tween Sorio and Montebello. The famous foflil fifhquar- 
ly at Bolca, fo well known to all the curious in Europe, 
is only an unburnt, calcareous, and flaty point, or fide 
promontory, as it were, of the higheft part of the fame 
vulcanic branch, that defcends into the valley, from the 
church and village of Bolca, which are built upon it. 
This point within unites immediately with the lava^ 
forming, in a manner, an integral part of the fame hill. 
In other parts again, and particularly at Ronca, alfo in 
the Veronefe territory, a few miles to the north- weft of
