Mr, Lloyd’s Account of an Earthquake. roj 
lowing account of an ingenious friend of mine, who is con- 
cerned in the great copper mine at Paris Mountain, and was at 
that time within a mile of the mine at his own houfe. 
44 I perceived the earthquake to begin at Amlwoh at 40' paft 
44 eight o’clock at night, on Saturday the 5th of Oftober. The 
44 fhock was great and alarming. The houfe in which I was 
44 w'as fhaken terribly, and underwent feveral vibrations for 
44 the continuance of near a quarter of a minute. I thought 
44 it moved from N.E. to S.W. but was not certain. It was 
44 attended with a rumbling noife, as loud as thunder, and 
44 like it juft before it ceafes. I have made an enquiry at leveral 
44 diftant parts in the ifland to the S.W. about it, to have found 
44 out, if pofTible, at what rate it moved, but in vain.” 
At the time it was felt in the places I have mentioned, I was 
at St. Afaph with fome other gentlemen, looking over fome 
parifh accounts ; but none of us perceived it, though it was 
perceived by a relation of mine, who was then alone, reading 
at the diftance of a mile and a half from us, and in the line 
between Anglefey and Mold, fo that I was probably further 
north than the fhock reached. I judge every phenomenon of 
this kind to be interefting to the fpeculative oblervers of na- 
ture. You may probably be of the fame opinion ; and if you 
are, and fhould think this imperfect account of fufficient con- 
fequence, you will pleafe to lay it before the Royal Society. 
I have the honour to be, &c.
