eight and nine feet, and floated two veflels before 
quite dry, but all fmoothj no fea broke. 
In the little harbour of Heyle, about four miles 
north of the Mount on the Severn fea, the agitation 
did not make its appearance till an hour and a little 
more after the ebb began, which mufl: be full an 
hour later than with us, and is eafily accounted for 
by the circuit of land at the extremity of this county, 
which the fwell mufl; have made before it could 
reach into the north chanel to St. Ives and Heyle, 
In this inland half-tide harbour it continued viflble 
but an hour and half ; the greatefl: flux was about 
the middle of that time, the furgc being at that time 
feven feet high 3 but in general it rofe and fell but two 
feet only, owing, as I fuppofe, to the force and quan- 
tity of water being broke in its advances into fo re- 
tired a creek. 
At Swanfea, in Wales, further up in St. George’s 
chanel, where their ebb is later fl:ill than in Heyle, 
I find the agitation was proportionably later than 
with us, and was not obferved till after two hours 
ebb, near three quarters after fix. 
At Kingfale, in Ireland, more indeed to the north 
of us, but more open to the Atlantic ocean than 
Swanfea, and farther to the weft, the agitation reach’d 
not a full hour after us, but above two hours fooner 
than at Swanfea, all tending to ftiew, that the force 
came from the fouth and fouth-weft. 
What relation thefe little palpitations or tremulous 
rebounds of the fea (for, in our parts, we may tliank 
God they were no more) had to the dreadful con- 
vulfions on the coafts of Spain and Portugal, whe- 
ther they were the fainter parts of that deplorable
