rfnattered by craters. The most elevated summit, Inclin'1^ 
to the S. W.. is, agreeably to Spallanzani, about a mile 
height. 
in this volcanic mountain the effects of a constai^ 
active fire are every where visible, heaping up, destroyi’’^' 
changing, and overturning every instant what itself 
produced, and incessantly varying in its operations. At 
distance of one hundred miles the flames it emits are vi**' 
ble, whence it has been aptly denominated tlie light-hoU*^ 
of that part of the Mediterranean sea. 
From the more elevated summit, all the inner part of 
burning crater, and the mode of its cniption, may be se®**' 
It is placed about half way up, on the N. W. side of 
mountain, and has a diameter not exceeding 250 
Burning stones are thrown up at regular intervals of sev^'' 
or eight minutes, ascending in somewhat diverging mf' 
While a portion of diem roll down towards the sea, tlj^ 
greater part fall back into the crater j and these being ag^^^ 
cast out by a subsequent emption, are thus tossed ai><5® 
I’lnti'l they are broken and reduced to ashes. The volcaD?' 
ihowever, constantly supplies others, and seems inexhausf*' 
ble in this species of productions. Spallanzani afiBrt*'^ 
tliat, in the more violent eruptions, the ejected matter ris®* 
to the height of half a mile, or even higher, many of ^ 
ignited stones being thrown above the highest summit 
tlie mountain. 
The erupted stones, which appear black in the day-tint^ 
have at night a deep red colour, and sparkle like fire»work* 
Each explosion is accompanied by flames or smoke, 
latter resembling clouds, in the lower part black, in 
upper white and shining, and separating into globular 
inegular forms. In particularly high winds from the S. 
S. E. the smoke spreads over every [>art of the ish'»“' 
Spallanzani observed this volcano on a particidar nig*’^' 
when the latter of these winds blew with' great viole0‘^^ 
The clear sky exhibited the appe:trance of a beautiful aui'oj'* 
borealis over that part of the mountain on which the v‘’‘' 
cano is situated, and which from time to time became 
red and brilliant, in propiirtion as the ignited stones 
thrown to a greater height. The violence of the con'-ad' 
sions depends on that of the wind. ^
