feconds before the fliock was intirely over, it being, 
then thirty-one minutes after four. People, I per- 
ceive, differ very widely refpedling the whole dura- 
tion ,of the earthquake, from the firft apparent fym- 
ptoms of it, till it was intirely over, fome fuppofing 
it to have been fix or feven minutes/ fome four or 
five, and others fcarce more than one. Accordine 
to the beft computation I am able to make, which 
is from what I did daring the continuance of it, re- 
moving from one place to another, as related above,, 
I think it could be but little more, and certainly not 
much lefs, than two minutes. There was another 
fliock about an hour and ten minutes afterwards, 
which, though fmall in comparifon to the former, 
was yet univerfally perceived by thofe who: were 
awake. The vifible effedfs of the earthquake are 
very confiderable in the town ; to be fure much more 
confiderable than thofe of any other earthquake,, 
which has been known in it. Many chimnies, I 
coniedture (from obfervation) not much lefs than an 
hundred, are levelled with the roofs of the houfes : 
many more, I imagine not fewer than 1 2 or i yoa 
ace ihattered, and thrown down in part ; fo that in 
fome places, efpecially on. the low loofe ground, 
made by encroachments on the harbour, the fireets 
are almoft covered with the bricks that have fallen.. 
Some chimnies, though not thrown down, are 
diflocated, or broken feveral feet from the top, and 
partly turn’^d round, as upon a fwivel > fome are: 
flioved on one fide horizontally,, jutting over, and 
jufi; nodding to their fall : the gable ends of feveral 
brick buildings, perhaps of twelve or fifteen, are 
thrown down, and the roofs of fome houfes are.
