LETTER XXir. 
Accoimt of the Earthquake felt in Penfylvania, 
Novem. i 8, 1755’, iu a Letter to Peter Col- 
linfgn, F. R. S. dated at Philadelphia, Decern, i. 
1755 - 
Read Mar. 1 BOUT four of the clock the 18th 
November lafl^ this province 
was pretty generally alarmed with the fliock of an 
earthquake, which occafioned great confternation, 
but I do not hear of any damage that enliied, unlcfs 
the breaking fome China-ware and glafles. I heard 
no noiie like that of a rulhing' wind, which was 
heard in? many places ; but felt a gentle fhaking of 
my bed, in fuch a manner as convinced me what it 
was, which continued to ihcreafe, and the windows 
by the increafing trepidation of the earth began to 
rattle ^ fome China on a cheft of drawers were moved 
pretty much. As I conjedtured, it gradually increafed 
for one minute, to fuch a degree as to open my cham- 
ber door,, by drawing the bolt of the lock out of 
the ftaple. 
Some people think they felt its continuance five or 
fix minutes, but I think it did not exceed two, nor 
was it lefs. I felt the fhock of the two earthquakes 
in England j but they were little in comparifon to 
this. - ■
