half an Hour after 5 in the Morning. It was much 
ftronger than that which happen'd in February ; two 
great Shocks being felt prcfently after each other. 
Thofe who were out of Doors felt the Ground 
fhake under them very fenfibly s whereas, in the 
former, few were fenfiblc of the Shock, except 
thofe who were in Houfes. I do not hear of any 
Mifchief done by it in this Neighbourhood $ neither 
can I learn that it extended farther Weft ward than 
the former. I am very well allured, that it was 
flrongly felt at Fulham , and at Turnham-Green. 
Several were fenfible of a fmaller Shock about 
3 the fame Morning } and fome talk of unufual 
Appearances in the Air. But this laft Circumftance 
feems not very well attefted. For my own part, I 
look'd out of my Chamber-Window to the S. W. 
at a Quarter after 5, and only perceived it to be a 
grey Morning, fuch as ufually predi&s a fine Day. 
I am, Sir, with the greateft Refpedt,
