and thofe better related, than any other earthquake 
of which we have an account. 
2. That thefe concuffions fhould owe their origin to 
fomething in the air, as it has fornetimes been imagined, 
feems very ill to correfpond with the phasnomena. 
This, I apprehend, will fufficiently appear, as thofe 
phasnomena are hereafter recounted j nor does there 
appear to be any fuch certain and regular connexion 
between earthquakes and the fate of the air, when 
they happen, as is fuppofed by thofe who hold this 
opinion. It is faid, for inflance, that earthquakes 
always happen in calm ftill weather : but that this is 
not always fo, may be feen in an account of the 
* earthquakes in Sicily of 165)3, where we are told, 
“ the fouth winds have blown very much, which 
“ f ill have been impetuous in the mold fenfible 
cc earthquakes, and the like has happened at other 
tc times.” 
3. Other examples to the fame purpofe we have 
in an account of the earthquakes that happened in 
New England in 1727 and 17283 the author of 
with fome additional ones, in “ The Hiftory and Philofophy of 
“ Earthquakes,” (a work well worth the perufal of thofe, who 
are defirous of being acquainted with this fubjedf). The author 
of it has given us, belkies the aforefaid fadfs, a very judicious 
abridgment of ten of the moft confiderable writers upon the fub- 
jech I have taken the greateft part of my authorities either from 
this author, or the Philofophicai Tranfacfions, that thofe who 
would wifh to examine them, may have 2n opportunity of doing 
ft the more eafdy 3 fome things only, which were not to be met 
with in thefe, and which yet were neceflary to my purpofe, I* 
have been obl'ged to feek for elfewhere.
