A modern writer also reminds us, that these effects are not so local as some would have us believe ; for on the opposite side of the Bay of Naples, on the Sor- rentine coast, which, as well as Puzzuoli, is subject to earthquakes, a road, with some fragments of Roman buildings, is covered to some depth by the sea. In the island of Capri, also, which is situated some way at sea, in the opening of the Bay of Naples, one of the palaces of Tiberius is now covered with water, t They who have attentively considered the effects of earthquakes, before enumerated, as having occurred during the last 140 years, will not feel astonished at these signs of alternate elevation and depression of the bed of the sea and the adjoining coast during the course of eighteen centuries; but, on the contrary, they will be very much astonished if future researches * Voy. datis la Campanie, tome ii. p. 162. f Mr. Forbes, Physical Notices of the Bay of Naples.
