When feen from the fea, on the fouth- 

 eafl: fide, at the diftance of two or three 

 miles, this ifland has the appearance of an 

 obtufe cone, but with a confiderable incava- 

 tion on one fide. This incavation has no 

 refemblance to a crater, and on a nearer ex- 

 amination we find it is only a lower part 

 of the mountain. In fad, we perceive no 

 marks of the mouths of ancient volcanos in 

 the whole circuit of Alicuda ; either becaufe 

 they have never exifl:ed there, or becaufe all 

 traces of them have been effaced by time or 

 fome other deftructive agent. I have dif- 

 covered the appearances of a true crater no 

 where but in the higheft part of the ifland, 

 where there is a hollow, not very deep in- 

 deed, but about half a mile in circumfe- 

 rence ; and I incline to believe it to have 

 been a crater, from finding there a group 

 of lava diverging as from a centre over the 

 body of the ifland. 



I examined the lavas which cover the 

 fides of this mountainous ifland, at leaft: 

 where I could reach them without danger,
