Misc. Subj. XL. Vol. IV. No. 44., REMARKABLE VOLCANICK OBJECTS OF THE LOWER ITALY., Fig 1. The Solfatara., 1 lie Solfatara is a narrow valley near Naples about 500 paces broad and 800 long. It lies between craggy rocks, and probably ows its oi'igin to a funk Volcano. It is, as it may be laid, the great manufacture of Nature for Ammoniac and Suiphur wliich by the beat of the fubterraneous fites are hère continually produced in abu'ndaiice. The ground is every where warm, in some places quite hot. Hère and there thick fuîphrtreous vapours break forth from the clefts especially those of the opening N. 3. at the end of the valley are forced out with great noife; they generali)" rife to a great height in the air, and fhine at night. Upon the sides of these openings fhoots the Amoniac and Sulphur or Briirrstone which is gathered and manufactured in the building N. I. at the other end of the valley. The whole ground of the Solfatara is white and consists of différent minerais. It trembles and founds when walked upon; but lying on the sround one hears a noife like that of boiling vvater. On the north of the valley these fubterraneous waters fall in a low and dark ground into a stinking brook. On the Eaft a small pond is feen, where the water is conltantly bubbling like boiling water though the heat is far inferiour to that uf boiling vvater. Ail these phenomena are effected by the fubterraneons lires which continually struggle under ground, though they nevèr break out into fiâmes., Fig. 2. Profpect of Stromboli., Stromboli is one of the small isles of Lipari between Naples and Sicily. The whole island consists almost entirely of a high conick mountain which rifes from the fea and whofe fummit N. I. is burning like a Volcano and emitting fmoke and fiâmes beyond the reach of hiftory and tradition. THough this little island appears wafte and defolate at a diftance, yet approaching its coaft, one feon perceives some feattered liutts, orchards and vineyards, so that the inhabitants whofe number amounts to about 1500, may be faid to live above and betwixt frre and fiâmes. Familiär with the danger they feem to defy it, for sometimes the fiâmes break out on lèverai places between the houles and gardens at the foot of the mountain. (N. 2.). The mufeadine and malmfey-wine which grows upon this hot-bed of Nature, is quite excellent.
