lated that a shock was felt in Paris, Navarre, Cologne, Aix- 

 la-Chapelle, Maestricht, the Hague, Amsterdam, &;c. The 

 time of its occurrence at all these places was, as nearly as pos- 

 sible, the same. The direction of the motion in England agrees 

 with the supposition that the shocks were identical, being from 

 E. to W. The district most affected by this earthquake seems 

 to have been near Cologne ; a great rent was formed in a 

 mountain there. 



(6.) On the 18th and 20th Nov. 1756, shocks were felt in 

 different parts of Argyleshire, and chiefly at Rothsay and In- 

 verhallan. On the last of these days, there was an earthquake 

 at Malta. 



(7.) On the 3d Jan. 1768, the register shews that shocks 

 were felt in Shetland and in Northamptonshire. 



(8.) On the 30th Dec. 1789, it is mentioned in the Trans- 

 actions of the Royal Society of Edinburgh, that a shock was 

 felt simultaneously at Parson''s Green, near Edinburgh, and at 

 Florence. 



(9.) On the 13th Aug. 1816, when the remarkable earth- 

 quake which agitated the northern half of Scotland occurred, 

 Signor Gemallaro* relates that a loud noise was heard from 

 Etna, and which was caused (as he subsequently ascertained) 

 by a portion of the interior of the great crater falling in. 



(10.) On the 20th Feb. 1818, as the register shews, shocks 

 were felt at Inverness, and in Lincolnshire. On the same day 

 a series of earthquakes commenced in Sicily, which, on the 

 28th February, destroyed Catania. 



(11.) On the 18th Sept 1833, when an earthquake was felt 

 at Chichester, and on the sea off that part of the English 

 coast, the towns of Arica and Tacna, in Peru, were utterly de- 

 stroyed. 



(12.) On the 25th August 1834, an earthquake was felt at 

 Comrie, on which day, as well as on that preceding and on 

 that following, Vesuvius was in violent eruption. 



(13.) On the 22d Sept. 1834, when the shock of an earth- 

 quake was felt at Chichester, the city of Tacna, in South Ame-
