120 Mr Milne on Earthquake'Shocks felt in Great Britain. 



1833. 

 June 11. North of Manchester. 



Sept. 18. At 10 A.M. Chichester, Birdham, Llphook. Barometer 29.26, 

 the air very sultry, warm, and still ; wind from S. and SW. 

 On previous evening, a brilliant aurora with meteors falling. 

 A rushing wind heard before the shock. The shock produced 

 a tremor, followed by an undulation. The pheasants crowed. 

 The shock was felt in a boat in Chichester harbour, as if it 

 had struck a rock. To a person in an old cottage, the shock 

 resembled the sudden turning of a powerful steam-engine or 

 thrashing-machine. In solid buildings, the shock was like 

 the falling of a weighty body, followed by a prolonged undu- 

 lation. 

 Nov. 13. At 2^40' A.M., Chichester (Dorsetshire). A thick fog preceded 

 it on previous day, which came from E., which continued till 

 9 A.M. on 13th. A distinct low sound preceded shock, 

 which consisted of a number of undulations rapidly succeed- 

 ing each other. Another and much slighter shock occurred 

 at Chichester about 6 a.m. 

 This thick fog said, by an observer in Dorsetshire, to be pre- 

 cisely similar to the fog which accompanied the Lisbon 

 earthquakes in 1807 and 181G. This fog commenced on 

 the 12th, succeeding heavy rain on the 11th November. 

 Numerous meteors observed in North America at 3 a.m. on 

 13th November 1833. 

 1834. 



Jan. 23. At 2^ 45' a.m. Longfleet near Poole (Dorsetshire), Liphook, 

 Famhurst, Petworth, Pulborough, Bognor, Portsmouth ; ba- 

 rometer 30 inches, but barometer had previously risen and 

 fallen very capriciously, without any corresponding change on 

 weather. Morning of previous day was rainy, foggy, and 

 warm. At time of shock, air was calm, but instantly after, wind 

 rose and blew strong from S W. with rain and lightning. The 

 same humid weather prevailed up to close of January, and 

 season was a fortnight nearly in advance, up to end of March. 

 A tremor was felt during the shock, which was followed by 

 several undulatory movements, with two-thirds of a second 

 intervening betwixt each. The undulation was at Stansted 

 House from W. to E., and appeared to be single. It lifted a 

 bed there. At Pulborough, three distinct shocks were felt in 

 quick succession. The centre of intensity was a few miles 

 NW. of Chichester. The shock was not felt on Portsdown 

 hill, but along the north and south sides. All the shocks 

 were more severely felt at the lowest places. 

 Feb. 20. At 2 aIm. Chichester, a slight shock.
