of the IJland of Ponza. 373 
tiles, with a like infcription, had been dug up on the fame fpot, 
and had been made ufe of in building the church and barracks 
newly eredted in this ifland. Another fragment of a tile was 
likewife found here, and given to me, with the following 
infcription : 
SAB. A PI. 
which the fame antiquary explains, sabinae avgvstae, Piae 
Imperatrici dicatum Balneum ; but, I believe, tfhere is no men- 
tion in ancient authors of Sabina having been at Pandataria : 
of Julia’s banifhment to this ifland there can be no doubt. 
Between Ventotiene and the ifland of Ponza, and from the 
latter at the diftance of about twelve miles, a group of rocks 
- 
rife feveral feet above the furface of the fea. They are called 
the Botte , and are compofed of a compact lava ; probably they 
are the fmall remains of another volcanic ifland, the fofter 
parts of which may have been carried off and levelled by the 
a&ion of the fea, which is open and violent here. 
The 20th of Auguft I arrived at the ifland of Ponza, about 
thirty miles from Ventotiene, and the next day I went round 
it in my boat. It is near five miles long : its greatefl: breadth 
not more than half a mile, and in fome - parts not more than 
five hundred feet. It is furrounded by innumerable detached 
rocks, fome of them very high, and mofl: of which are of 
lava ; in many are regularly formed bafaltes, but none in large 
columns. In fome parts the bafaltes have a reddifli tint of 
iron ochre, are very fmall, and irregularly laid one over another. 
Some mafles of them are in a perpendicular, others in an hori- 
zontal, and others again in an inclined pofition : and the rocks 
themfelves, in which thefe mafles are found, are lava of the 
fame nature as the bafaltes. At firft fight thefe rocks have 
very much the appearance of the ruins of ancient Roman
