are feveral kinds of this Stone, which differ much 
one from the other in Colour : They are ranked 
among the Jafpers. 
The Country round Mount Vefuvius abounds 
with a kind of Stone, which in its Eruptions 
iffues from it in great Abundance in form of 
a burning Rivulet, deftroying every thing in its 
wiy : When the Eruption ceafes, this Subftance as 
it cools hardens, and is called Lava : it is a very 
hard Stone, takes a fine Polifh, and is fit for many 
Ufes, being frequently manufactured into Boxes, 
Tables, &V. It is fo plentiful, that in Naples the 
Inhabitants very commonly make ufe of it for pav¬ 
ing the Streets. There is a fine large cubic Piece 
of this Lava preferved in the Hall. 
In another Part is a painted genealogical Tree 
of a Noble Venetian Family *, and, befides all I have 
mentioned, there are a great Number of Epitaphs 
and Infcriptions (on the original Stones, by Acci¬ 
dent found) in Latin, Greek , and other Langua- 
ges. 
The Staircafe and fome of the Cielings are orna¬ 
mented with good Frefco Paintings, of which I 
fhal 1 enter into no long Defcription. On the Side 
of the Staircafe, Cafar and his military Retinue are 
feen, with the Chiefs of the Provinces he had in 
part fubdued attending on him, and others on their 
Knees, imploring his Protection or Afliftance. 
In a Compartment are the Bacchanalia, or Feafts 
and Sacrifices of Bacchus. 
In another the Rivers Nile and Tiler are repre- 
fented by gigantic Figures emblematically orna¬ 
mented : and there are Views of beautiful Land- 
fcapes at a Diftance, and feveral fine Pieces of 
Architecture.
