and continued 5 minutes, and consequently near twice as long as that of Peru, 

 the duration of which was only 3 minutes. If every thing was not destroyed 

 here, it seems particularly owing to the solidity of the buildings. The inhabit- 

 ants had scarcely begun to recover from their first terror, when they saw them- 

 selves plunged into new alarms. At 10 minutes after 1 1 they saw rolling towards 

 the city a tide of the sea, which passed over the parapet of 6o feet above the 

 ordinary level of the water. At 30 minutes after 1 1 came a 2d tide ; and these 

 2 were followed by 4 others of the same kind, at 50 minutes after 11, at 12. 

 o'clock 30 minutes; 1 o'clock 10 minutes; and 1 o'clock 50 minutes. The 

 tides continued, with some intervals, till the evening, but lessening. They have 

 ruined 100 toises of the rampart; part of which of 3 toises length, and of their 

 whole thickness, were carried by the torrent above 50 paces. A great number 

 of persons perished on the causey, which leads to the isle of Lesu. Seville has 

 been greatly damaged. St. Lucar and Cheres have likewise suffered much ; and 

 Conel is said to be entirely destroyed. 

 jin Account of the Earthquakes that happened in Barbary, inclosed in a Letter 



from General Fowke, Governor of Gibraltar. Communicated by Philip Lord 



Viscount Royston, F.R.S. p. 428. 



AtTetuan the earthquake began, the 1 st of November, at 10 in the morn- 

 ing, and lasted between 7 .and 8 minutes ; during which space the shock was 

 repeated 3 different times, with such violence, that it was feared the. whole city 

 would fall down ; but the only damage that resulted was the opening or parting 

 of some of the walls of sundry houses. It was likewise observed that the waters 

 of the river Chico, on the other side of the city, and those of a fountain, ap- 

 peared very red. 



At Tangier, the earthquake began about the same time, but lasted longer 

 than at Tetuan ; the trembling of the houses, mosques, &c. was great, and a 

 large promontory of an old building near the city gate, after 3 shocks, fell down 

 to the ground, by which 5 shops were demolished ; the sea came up to the very 

 walls, a thing never seen before, and went down directly with the same rapidity 

 as it came up, as far as the place where the large vessels anchor in the bay, leav- 

 ing upon the mole a great quantity of sand and fish. These commotions of the 

 sea were repeated 18 times, and continued till 6 in the evening, though not with 

 such violence as at the first time. The fountains were dried up, so that there 

 was no water to be had till night : and as to the shore-side, the waters came up 

 half a league inland. 



At Arzila, it happened about the same time, but the damage was not great. 

 At the coming up of the sea 7 Moors, who were out of the town walls, were 

 drowned ; and the waters came in through one of the city gates very far. The 

 water came up with such impetuosity, that it lifted up a vessel in the bay
