 to se., at three quarters past one, a.m., and in the same month 

 a tornado and earthquake in Jamaica. Contemporaneous, 

 also, with the earthquake at Chichester was the tremendous 

 eruption of Vesuvius (the greatest ever recorded), on August 

 27, 28, 29., which was preceded by smaller eruptions, at the 

 beginning of the month, and by the drying up of wells and 

 fountains, and which, till September 3., threw out cinders and 

 ashes. The earthquake at Chichester, on Aug. 27. } was pre- 

 ceded by a shock at Melton Mowbray, on Aug. 4., at half past 

 six p.m., which was accompanied by a meteor and great noise : 

 a shock was also experienced at Monica, Gal way, in August, 

 when a quarter of an acre of land sunk 75 feet. The floating 

 island on Derwentwater appeared on August 8. above water, 

 its last rising being from June 10. to July 19. 1831. It dis- 

 appeared after heavy rains on Sept. 14. On June 5. there 

 were a very heavy gale and rain from s.w. in England.* 

 On that day occurred an earthquake at Cephalonia, at four 

 P.M., preceded by dreadfully hot weather ; the shocks were 

 more severe than ever remembered there. Carthagena, 

 Rio Hache, and Maracaibo were also shaken, on the same 

 day, by renewed earthquakes. On June 19. there was a 

 sinking of the earth at Kipon : Vesuvius was in eruption on 

 the same day ; and on the 26th occurred an earthquake at

 the harbour.

 the 22d to the 24th, Santa Martha, in New Grenada, was 

 visited by forty shocks of earthquake. On the 1 Oth, Malta

 gatoro, Pontremoli, &c. Barbadoes was visited by violent 

 gales on the 6th and 7th. Mayence was visited by a dread-

 said to be chased in by porpoises ; but, on enquiry, I think there was
