Profeffor WILLIAMS, on Earthquakes, 277 
There were. feyeral {mall fhocks foon after this of Novem- 
ber 18 .—One. in about an hour and a quarter after the firft, 
viz. at $^ 29'. A fecond, on November 22, at twenty-feven 
minutes after eight at night. .A third, on December 19, at 
10^ P. M. Their wi/ence and duration was {mall ; their 
caurfe, much like that of the great fhock ; and. their extent, 
fuch as to be pretty generally felt through the country. Many 
others, but very fmall, were felt in different parts of the Maf- 
fachufetts and. New-Hampfhire, for feveral months after. 
In:1757, there was another earthquake ; which, tho’ {mall, 
was generally felt... I cannot find any printed. account of. this 
fhock, and, therefore, can only mention fome general obferva- A 
tions, . which I then made of it. Be came on July 8, N. ‘Sivat er: 
about 2h 20',, P. M.. I was then i in an open field, furrounded 
with pretty high hills, from fouth-weft. to north-eaft, i in com- 
pany with another perfon The. firft. thing we perceived, was 
a fmall noife, like that of a rifing wind, which feemed to be at 
a great diftance, but fwiftly advancing. It was half a minute 
before there was any fhock. ‘This I inferred, not barely from 
y conjedure. I was then able to 2 make, » hich in 2 fan of 
Repa muft be greatly. uncertain, but 
after hearing. the noie, we had enquired. of ‘each other hat it it 
cga bs s and as there was no fhake, concluded it was not an

veratión I well remember ; and am certain it muft haye taken 
up. Balt, a minute, if not more, - The ai isfelf "was not of very 
. great 
ground z ie parts of an zen which was quic AR any T de bad been for, | 
feven years before, and about. fve or fix times as great as what is common in this dd 
'eountry. The’ account of this earthquake is collected from Profeffor Winthrop’s 
Lesure; and account of it in Phil. Tranf for 1757, at. 1. aud from Disc Ghaun- 
cey’s and Mayhew’s accounts of it.
