te vember laft, I find you had a remarkably fudden* 
“ flux and reflux of the fea at Portfmouth and 
“ other parts of the coaft, which was agitated in 
* c like manner, at the fame time, on the coaft of 
tc America, and all thefe iflands. The tide rofe 
<c here twelve feet perpendicular feveral times, 
Cc and returned almoft immediately : the lame at 
£c Barbadoes. At Martinique, and moft of the 
a French iflands, it overflowed the low land, and 
<c returned quickly to its former boundaries. The 
“ people at Barbadoes were never more aftoniflied ; 
tc . the riling water in Carlifle Bay appearing as black

<c Since I wrote this, I have taken a more par- 
ticular account of the flux and reflux above-men- 
^'tioned, from an obferving man of this ifland ; 
<c who remarked, that here it began at half an hour 
<c after three in afternoon, on the ift of November 
u laft; and flowed, every five minutes, five feet per- 
cc pendicular, till as much after fix, without any 
“ violent difturbance on the furface of the water. 
P. S. In Martinique, in that remarkable flux and 
u reflux of the fea, it was in fome places dry 
<c for a mile; and, in others, flowed into the 
sc upper rooms of the houfes, and deftroyed 
<c much coffee. At the ifland of Sabia, it flowed 
tc twenty-one feet ; and at St. Martin’s, a floop, 
<c that rode at anchor in fifteen feet water, was 
“ laid dry on her broadfide.” 
If the Royal Society have not yet had any more 
particular accounts of this matter from the Weft- 
Indies, the above is at their fervice ; and, with my
