water, destroying the fish. In a mill-pond, near Guildford in Surrey, a like 

 swell and agitation of the water was observed by several persons, one of whom 

 stood all the time on a bridge of wood, over the pond. Not the least tremor or 

 motion of the earth was felt in any of these places, or at the bridge at Guildford. 

 3. In the Parish of Cobham. By Sivithin Adee, of Guildford, M.D., F.R.S. 



p. 357. 

 A man, in the parish of Cobham, was watering a horse in hand, at a pond 

 close by the house, which is fed by springs, and had no current. The time he 

 fixes was about 10 in the morning, but their clock goes too slow. While the 

 horse was drinking, the water ran away from the horse, and moved towards the 

 south with swiftness, and in such a quantity, as left the bottom of the pond 

 bare ; then returned with such impetuosity, as made the man leap backwards, to 

 secure himself from the sudden approach of the water. It went back again to 

 the south, with a great swell, and returned agiiiii. On inspecting the place, 

 Dr. A. found the water must have risen above 1 foot. The ducks were alarmed 

 at the first agitation, and flew all instantly out of the pond. The man observed, 

 that there was a particular calm at this time of day. You will observe here were 

 tw.o fluxes and two refluxes seen distinctly. 



4. At Medhursl. By Mr. John Hodgson, p. 358. 

 As to the ponds near Medhurst, every body agrees, that there was an extra- 

 ordinary swelling of the water. The water was thrown several feet above its 

 banks, both at north-mill, at south-pond, and the pond in Lord Montacute's 

 park; and at the first of these, on its retreat, left some fishes on dry land. 

 5. At Cranbrook in Kent. By Wm. Tempest, Esq. F.R.S. p. 36o. 

 The people here are very much alarmed on account of an earthquake, which 

 happened last Saturday (Nov. the 1st). I felt nothing of it, but some people 

 fancied they did. I do not hear that the earth moved ; only the waters of several 

 ponds, in this and the adjacent parishes, were in such motion, that they over- 

 flowed their banks, then returned back, and overflowed the other side. 

 6. Near Tunbridge. By John Pringle, M. D., F. R. S. p. 36o. 

 The pond at Eaton-bridge, near Tunbridge, is about an acre in size, and across 

 it is a post and rail, which is almost quite covered by the water. Some people 

 heard a noise in the water, and imagining something had tumbled in, ran to see 

 what was the matter; when, to their surprise, they saw the water open in the 

 middle, so as that they could see the post and rail a good way down, almost to 

 the bottom, and the water dashing up over a bank about 2 feet high, and per- 

 pendicular to the pond. This it did several times, making a grejit noise. They 

 did not feel the least motion on the shore, nor wa.s there any wind, but a dead 

 calm.
