3- \Ve obfervc, the vulgar Solution of fubterra- 
ncous Eruptions receives no Countenance from afl 
that was fecn or felt during thefe Earthquakes: It 
would be very hard to imagine how any fitch thing 
could fo fuddenly and inftantaneoufly operate -thro’ 
this vaft Space, and that in fo fimtkr and tender a 
manner, over the Whole, thro' fo great a Variety 
as well as Extent of Countin’, as to do no Mifehief.' 
A philofophical Inquirer iii ' North amptcnjbire, . 
w ho had his Eye particularly cn this Point, takes 
notice there were not any FifTures in the Ground, 
any I’ulphureous Smells, or Eruptions, arsy-wh'ere per- 
cciv’d, fo as to favour internal Convulfions of th'c 
Earth yet we leant, from a Letter,’ at Uppingham 
in Rutland, that a Plaifter Floor became crack'd 
thereby. Thele kind of Floors are frequent in this 
Country; what we cali Stucco in London ; and it 
gives us a good Notion of the uuJuhtory Vibration 
produc'd by an Earthquake ; which fome have com- 
pared to that of a mufical String ; others, to that 
of a Dog, or a Hoi fe, {baking themfelves whemthey 
come out. of the Water. 
4. The former Earthquake, that happened at 
Grantham, Spalding , Stamford (which Towns lie in 
a Triangle) took up a Space which may in grofs 
be accounted a Circle of 20 Miles in Diameter; 
the Centre of which is that great Morals called c Deep- 
ing-Fen. This comprehends 14 Adilesof that 20 in 
Diameter ; and where, probably, the elc&rical Impref- 
fon was firft made. Much the major Part of Deep- 
ing Fen is under Water in the Winter; underneath 
is a perfect Bog : Now it is very obvious how little 
favourable fuch Ground is for fubterraneous Fires.
