the former) and at the diftance, perhaps, of ten or 
fifteen leagues from the coaft. For, 
95. Fir)}, The direction, in which the earthquake 
arrived at Lifbon, was from the north-weft ; at Ma- 
deira it came from the north-eaft ; and in England 
it came from the fouth-weft ; all of which perfectly 
agree with the place aflumed *. 
9 6. Secondly , The times in which the earthquake 
arrived at different places, agree perfectly well alfo 
with the fame point. And, 
97. Thirdly , The interval between thefe, and the 
time of the arrival of the fubfequent wave, concur in 
confirming it. That all this might appear the better, 
I have fubjoined the following table, afluming the 
point, from whence I compute, at the diftance of 
about a degree of a great circle from Lifbon, and 
a degree and half from Oporto. In confequence of 
this fuppofition, I have added three minutes to the 
interval between the time when the fliock was felt 
at Lifbon, and at the feveral other places. The firft 
column in the table contains the names of places ; 
the fecond, the diftances from the aflumed point, 
reckoned in half degrees ; the third, the time that 
the earthquake took up in travelling to each, ex- 
prefled in minutes j and the fourth contains the time 
in which the wave was propagated, from its fource to 
the refpedtive places, exprefled in minutes likewife. 
* All thefe dire&ions, together with the times when the earth- 
quake, as well as the fucceeding wave, arrived at different places, 
(two or three only excepted) are taken from the 49^ volume of the 
Philof. Tranf. and the Hift. and Philof. of Earthq. To thefe, I 
muft refer the reader for the particular authorities, which, as they 
are very numerous, I was not willing to quote at length.
