PANTELLAEIA, the largest of the outlying islands belonging to 

 Sicily, and containing one of the twelve Sicilian volcanoes, 

 lies 53 miles from Sicily, and 34 from the coast of Tunis. It is 

 8^ miles in length and 4^ in breadth, with an area of 25,423 acres. 

 Its Montagna Grande rises 2742 feet, and it has other mountains of 

 less height. The south and east sides have precipitous cliffs ; but 

 at the northern extremity the ground slopes gently downwards to 

 the coast with its little port. The town of Pantellaria has 3167 

 inhabitants ; and 4148 people live in the five country villages or 

 groups of cottages. Volcanic rocks, and rich soil from their decora- 

 position, constitute the country. The volcano itself had numerous 

 prehistoric eruptions, from centre and sides. As a member of the 

 Lipari, Vulcano, and Ischia system, it maj'^ not be regarded as quite 

 extinct, especially since earthquake shocks, and a submarine eruption 

 not far from the coast, occurred in October last. It may be noted 

 that an upheaval of the sea-bed for 40 fathoms would convert the 

 Adventure Bank, now about 40 miles from Pantellaria towards 

 Marsala, into an island, 14 miles long, and 3 miles broad, and 

 rising nearly 200 feet above sea-level. Thirty-seven miles N.E. of 

 Pantellaria, and 25 miles from the south coast of Sicily, the Graham 

 Shoal remains where the submarine volcano in 1831 formed the
