land, and others lying on land were fet afloat. At Am- 
fterdam, about eleven in the forenoon, the air being per¬ 
fectly calm, the waters were fuddenly agitated in their 
canals, fo that feveral boats broke loofe ; chandeliers 
were obferved to vibrate in the churches ; but no motion 
ot the earth* or concuflion of any building, was’obferved. 
At Haerlem, in the forenoon, for near four minutes toge¬ 
ther, not only the water in the rivers, canals, &c. but 
alfo all kinds of fluids in fmaller quantities, as in coolers, 
tubs, backs, &c. were furprifmgly agitated, and dafhed 
over the fides, though no motion was perceptible in the 
veflels themfelves. In thefe fmall quantities alfo the 
fluid apparently attended prior to its turbulent motion; 
and in many places, even the rivers and canals rofe twelve 
inches perpendicular. At Leyden, between half an hour 
after ten and eleven in the forenoon, the waters rofe fud¬ 
denly in fome of thecanals, and made feveral very fenfible 
undulations, fo that the boats were ftrongly agitated. 
Round the ifland of Corfica, the fea was viole'ntly'agi- 
tated, and mod of the rivers, of the ifland overflowed 
their banks. In the city of Milan in Italy, and through¬ 
out that diftridt, fhocks were felt. At Turin in Savoy, 
there was felt a very violent (hock. In Swiflerland, many 
rivers turned fuddenly muddy without rain. The lake 
of Neufchatel fwelled to the height of near two feet above 
its natural level for the fpace of a few hours. An agita¬ 
tion was alfo perceived in the waters of the lake of Zu¬ 
rich. At the ifland of Antigua, there was fitch a fea 
without the bar as had not been known in the memory of 
man ; and after it, all the water at the w'harfs, which 
ufed to be fix feet deep, was not two inches. At Barba- 
does, about two in the afternoon, the fea ebbed and flowed 
in a furprifing manner. It ran over the wharfs and 
ftreets into the houfes, and continued thus ebbing and 
flowing till ten at night. 
The agitation of the w'aters was perceived in many 
places of Great Britain and Ireland. At Barlborough 
in Derbyfliire, between eleven and twelve in the fore¬ 
noon, in a boat-houfe on the weft; fide of a large body of 
water called Pibley Dam, fuppofed to cover at lead; thirty 
acres of land, was heard a ftirprilipg noife ; a large fwell 
of water came in a current from the fouth, and rofe two 
feet on the dam-head at the north end of the water. It 
then fubfided ; but returned again immediately, though 
with lefs violence. The water was thus agitated for 
three quarters of an hour; but the current grew every 
time weaker and weaker, till at laft it entirely ceafed. At 
Bufbridge in Surrey, at half an hour after ten in the 
morning, the weather being remarkably (till, without the 
lead wind, in a canal near feven hundred feet long and 
fifty-eight feet broad, with a fmall fpring conftantly run¬ 
ning through it, a very unufual noife was heard at the 
eaft end, and the water there obferved to be in great agi¬ 
tation. It ralfed.itfelf in a heap or ridge in the middle ; 
and this heap extended lengthwife about thirty yards, 
rifing between two or three feet above the ufual level. 
After this, the ridge vibrated towards the north fide of 
the canal, with great force, and flowed above eight feet 
over the grads walk on that fide. On its return back into 
the canal, it again ridged in the middle, and then heeled 
with yet greater force to the fouth iide, and flowed over 
its grafs walk. During this latter motion, the bottom on 
the north fide was left dry for feveral feet. This ap¬ 
pearance lafted near a quarter of an hour, after which the 
water became fmooth and quiet as before. During the 
whole time, the fand at the bottom was thrown up and 
mixed with the water; and there w'as a continual noife 
like that of water turning a mill. At Cobham in Surrey, 
between ten and eleven o’clock, a perfon was watering a 
horfe at a pond fed by fprings. Whilft the animal was 
drinking, the water fuddenly ran away from him, and 
moved towards the fouth with fuch fwiftnefs that the 
bottom of the pond was left bare. It returned again 
with fuch impetuofity that the man leaped backwards 
4w fecure himfelf from its hidden approach. The ducks 
QUAK E. 
were alarmed at the firft agitation, and inftantly flew all 
out of the pond. At Dunftall in Suffolk, the water of a 
pond rofe gradually for feveral minutes in the form of a 
pyramid, and fell down like a water-fpout. Other ponds 
in the neighbourhood had a fmooth flux and reflux from 
one end to the other. 
Near the city of Durham, about half an hour after ten, 
a gardener was alarmed by a hidden ru filing noife from a 
pond, as if the head of the pond had been broken down; 
when calling his eye on ihe water, he faw it gradually 
ri£e up, without any fluftuating motion, till it reached a 
grate which flood fome inches higher than the common 
water level. After this it fubfided, and then fwelled 
again; thus continuing to rife and fall during the fpace 
of fix or feven minutes, making four or five returns in the 
fpace of one minute. The pond was about forty yards 
long and ten broad. At Earfy Court, Berks, about ele¬ 
ven o'clock, as a gardener was (landing by’a fifh-pond; he 
felt a violent trembling of the earth, which lafted about 
a minute. Immediately after, lie obferved a motion of 
the water from the fouth to the north end of the pond, 
leaving the bottom at the fouth end altogether dry'for 
about fix feet. It then returned, and flowed at the fouth 
end, rifing three feet up the (lope bank ; and immediately 
after returned to the north bank, rifing there alfo about 
three feet. In the time between the flux and reflux, the 
water fwelled up in the middle of the pond, collected in 
a ridge about twenty inches higher than the level on each 
fide, and boiled like a pot. This agitation from fouth to 
north lafted about four minutes. At Eaton-bridge, Kent, 
in a pond about an acre in fize, a dead calm, and no wind 
ftirring, fome perfons heard a noife, and imagining fome- 
thing had been tumbling in, ran to fee what was the mat¬ 
ter. On their arrival at the pond, to their furprife they 
faw the water open in the middle, fo that they could fee 
a poft a good way down, almoft to the bottom. The wa¬ 
ter in the mean time dallied up over a bank two feet high, 
and perpendicular to the pond. This was repeated feve¬ 
ral times with a great noife. 
At Eyam-bridge, Derbyfliire, in the Peak, the over- 
feer of the lead-mines fitting in his writing-room about 
eleven o’clock, felt a hidden (hock, which very fenfibly 
raifed him up in his chair, and caufed feveral pieces of 
plafter to drop from the fides of the room. The roof 
was fo violently fliaken, that he imagined the engine fiiaft 
had been falling in. Upon this he immediately ran to fee 1 
what was the matter, but found every thing in perfect 
fafety. At this time two miners were employed in cart¬ 
ing the ore and other materials to be raifed up at the 
(hafts. The drift in which they were working was about 
120 yards deep, and the fpace from one end to the other 
fifty yards or upwards. The miner at the end of the 
drift had juft loaded his cart, and was drawing it along ; 
but he w r as fuddenly furprifed by a (hock, which fo terri¬ 
fied him, that he immediately quitted his employment, 
and ran to the weft end of the drift to his partner, who 
was no lefs terrified than himfelf. They dnrft not attempt 
to climb the (haft, left that fnould be running in upon 
them ; but while they were confulting what means they 
fliould take for their fafety, they were furprifed by a fe- 
cond fnock, more violent than the firft ; which frightened 
them fo much that they both ran precipitately to the 
other end of the drift. They then went down to another 
miner who worked about twelve yards below them. He 
told them that the violence of the fecon.d (hock had been 
fo great, that it caufed the rocks to grind upon one ano¬ 
ther. His account was interrupted by a third fnock, 
which, after an interval of four or five minutes, was fuc- 
ceeded by a fourth ; and, about the fame fpace of time 
after, by a fifth ; none of which were fo violent as the 
fecond. They heard, after every (hock, a loud rumbling 
in the bowels of the earth, which continued about half a 
minute, gradually decreafing, or feemihg to remove to a 
greater diftance. At Shirburn caftle, Oxfordftiire, at a 
little after ten in the morning, a very (Irar.ge motion was 
obferved
