Pàgina 100 - Herculaneum was swallowed up ; but we are informed by unquestionable authority, that "the matter which covers the ancient town of Herculaneum is not the produce of one eruption only; for there are evident marks, that the matter of six eruptions has taken its course over that which lies immediately above the town, and was the cause of its destruction. These strata are either of lava or burnt matter, with veins of good soil betwixt them...

Till now the afcent had been fo gradual (for the top of Etna is not lefs than 30 miles from Catania, from whence the afcent begins) as not to have been the leaft fatiguing; and if it had not been for the fnow, we might have rode upon our mules to the very foot of the little mountain, higher than which the canon our guide had never been: but as I faw that this little mountain was compofed in the fame manner...

From thefe circumftances, and from repeated obfervations I have made in the neighbourhood of Vefuvius, I am fure that...
