We are alarmed with frequent fhocks of earth*- Fyal iflan 4 
quakes. The mod violent ffiock we have had of late, Azores thC 
was on the 3 i ft of March laft (17). 
“ On the 31ft of March, the fea rofe to a great Terceira> 
<c hight, and fell again fo low, that the quays were 
" left dry ; all the lighters and fifhing-boats, that 
“ were hauled up in Portorico, were carried down 
<c into the bay, and broke to pieces upon the 
“ rocks (18).” 
N. B. About a fortnight after, feveral earthquakes 
(fucceffively more and more violent) ended not, till 
on the 20th three volcanoes threw out as many rivers 
of lava, of near a mile in breadth, and four yards 
high, which threatened defolation to the whole 
country, and continued over-running every tree and 
houfe, till the 24th (19). 
Thefe, Sir, are all the memorandums I could 
colled; in this place ; and it muft foon be feen, that 
they are lame and imperfed, not either diffidently 
precife as to time, or fo particular as to weather, 
place, and other circumftances, as might be wifhed j 
but, fuch as they are, (and I doubt not other papers 
may furniffi an additional number to others) I have 
thrown them into a table, under general heads, with 
a few dedudions, which rofe from their comparifon.
