parts of the Earth for feveral Leagues together : Witneis 
your laft Earthquake about four or five year ago, which 
was felt, (with little difference as to time J in England 
and Ireland. Another Confirmation of this, is, the man- 
ner theie trembling Fits are perform'd,- which is not all 
of a fuddain, like that of Gunpowder in a Mine, but is 
fmall at firft, afterwards gradually more terrible, like 
a growing TempefL A Third may be, the Obfervati- 
on of fome here in Naples, that when Mount Vefuve 
ceafes to burn, the Sulfaterra fends out its Fumes more 
violently, & vice verfay" Now this Sulfaterra is a Hill 
nezrVuzzolo, as diftant from Naples on the one hand as 
the Hill Vefuvio is on the other.; fo that 'tis more than 
probable Naples ftands upon a burning Arch, through 
which, as a. Pipe, thefe two furious Neighbours do re- 
ciprocally receive the.abo.vefaid Exhalation. Thisfeems 
to me a growing Evil to this wealthy and populous Ci- 
ty, and what may poffibly in time make good the Pre* 
di&ionof Sanazarius, who was born here.
