o’clock in the morning a fhock of an earthquake 
was felt at Cork j but I have not met any perfons of

ral boats were drove from their anchors, and cafl; on 
fhore. This, attended with violent thunder and light-

returned to its natural fltuation. 
Thefe are all the particulars I was a witnefs to, or 
could colled; from good authority. I am,
