which contains marine shells of recent species. The same 

 observer remarks that Porzio's account upon the whole cor- 

 roborates the doctrine of the cone having being formed by 

 eruption, in proof of which he cites the following passage : — 

 <■ But what was truly astonishing, a hill of pumice-stones and 

 ashes was heaped up round the gulf, to the height of a mile

 contained an hospital for those who resorted there for the 

 benefit of the thermal springs ; and it appears that there 

 were no fewer than three inns in the principal street. Had 

 Porzio stated that any of these buildings, or the ruins of 

 them, were seen by himself or others raised up above the 

 plain, a short time before the first eruption, so as to stand on 

 the summit or slope of a newly-raised hillock, we might have 

 been compelled, by so circumstantial a narrative, to adopt 

 M. Dufrenoy's interpretation. 



But in the absence of such evidence, we must appeal to 

 the crater itself, where we behold a section of the whole 

 mountain, without being able to detect any original nucleus
