phenomenon probably occasioned by the clouds having; acquired a great degree of heat in passing through the above-mentioned column of fire.

On the eighth, the mountain was quiet till towards six p. m when a great smoke began to gather over its crater; and about an hour after, a rumbling subterranneous noise was heard in the neighbourhood of the volcano ; the usual throws of red-hot stones and scoriae began and increased every instant. The crater, viewed through a telescope, seemed much enlarged by the violence of the explosions on the preceding night; and the little mountain on the top was entirely gone. About nine, a most violent report was heard at Portici and its neighbourhood, which shook the houses to such a degree as made the inhabitants run out into the streets. Many windows were broken, and walls cracked, by the concussion of the air on this occasion, though the noise was but faintly heard at Naples. In an instant, a fountain of liquid transparent fire began to rise, and, gradually increasing, arrived at last to the amazing height of ten thousand feet and upwards. Puffs of smoke, as black as can possibly be imagined, rapidly succeeded one another, and, accompanying the red-hot transparent and liquid lava, interrupted its splendid brightness here and there by patches of the darkest hue. Within these puffs of smoke, at the very moment of emission, a bright but pale electrical fire was observed playing briskly about in zig-zag lines. The wind was south-west, and, though gentle, was sufficient to carry these puffs of smoke out of the column of fire, and a collection of them by degrees formed a black and extensive curtain behind it; in other parts of the sky it was perfectly clear, and the stars bright. A fiery fountain of such immense magnitude, on the dark ground just mentioned, made the finest contrast imaginable; and the blaze of it, reflected from the surface of the sea, which was at that time perfectly smooth, added greatly to this sublime spectacle. The lava, mixed with stones and scoriae, having risen to the amazing height already mentioned, was partly directed by the wind towards Ottaiano, and partly falling, still red-hot and liquid, upon the top of Vesuvius, covered its whole cone, as well as that of the summit of Somma, and the valley between them.

The falling matter being nearly as inflamed and vivid as that which was continually issuing fresh from the crater, formed with it one complete body of fire, which could not be less than two miles and a half in breadth, and of the extraordinary height above mentioned, casting a heat to the distance of at leastsix miles round. The brush wood on the mountain of Somma was soon in a blaze; and the flame of it being of a different colour, from the deep red of the matter thrown out by the volcano, and from the silvery blue of the electrical fire, still added to the contrast of this most extraordinary scene. The black cloud increasing greatly, spread over Naples, and threatened the city with speedy destruction; for it was charged with electrical fire, which kept constantly darting about in bright zigzag lines. This fire, however, rarely quitted the cloud, but usually returned to the great column of fire whence it proceeded; though once or twice it was seen to fall on the top of Somma, and set fire to some dry grass and bushes. Fortunately, the wind carried back the cloud just as it reached the city, and had begun to occasion great alarm. The column of fire, however, still continued, and diffused such a strong light, that the most minute objects could be discerned at the distance of ten miles or more from the mountain. Mr. Morris informed our author, that at Sorrento, which is twelve miles distant from Vesuvius, he read the title page of a book by that volcanic light.

All this time the miserable inhabitants of Ottaiano were involved in the utmost distress and danger by the showers of stones which fell upon them, and which, had the eruption continued for a longer time, would most certainly have reduced their town to the same situation with Herculaneum and Pompeii.

The mountain of Somma, at the foot of which the town of Ottaiano is situated, hides Vesuvius from the view of its inhabitants ; so that till the eruption became considerable, it was not visible to them. On Sunday night, when the noise increased, and the fire began to appear above the mountain of Somma, many of the inhabitants flew to the churches, and others were preparing to quit the town, when a sudden and violent report was heard; soon after which, they found themselves involved in a thick cloud of smoke and ashes, a horrid clashing noise was heard in the air, and presently fell a vast shower of stones and large pieces of scoriae, some of which were of the diameter of seven or eight feet, which must have weighed more than 100 lbs. before they were broken, as some of the fragments which Sir William Hamilton found in the streets still weighed upwards of 60 1bs. When these large vitrified masses either struck against one another in the air, or fell on the ground, vivid sparks of fire proceeded from them, which communicated to every thing that was combustible. These masses were formed of the liquid lava; the exterior parts of which were become black and porous, by cooling in their fall through such a vast space; whilst the interior parts, less exposed, retained an extreme heat, and were perfectly red. In an instant, the town and country about it were on fire in many parts, for there were several straw huts in the vineyards, which had been erected for the watchmen of the grapes, all of which were burnt to the ground. A great magazine of wood in the heart of the town became one sheet of fire; and had there been much wind, the flames must have spread universally, and the inhabitants have perished in their houses; for it was impossible for them to make their escape by flight. Some, who attempted it with pillows, tables, chairs, the tops of wine casks, etc. on their heads, were either knocked down by the falling masses, or soon driven to make a speedy retreat under arches, and in the cellars of their houses. Many were wounded, but only two persons died of their wounds. To add to the horror of the scene, incessant volcanic lightning was darting its corruscations about the black cloud that surrounded the inhabitants, and the sulphureous smell and heat would scarcely allow them to draw their breath.
