form any tolerable Idea of the Nature of Springs 
and Fountains perpetually flowing, and that (gene- 
rally fpeaking) from the Creation of the World, 
we rauft needs conceive, that God Almighty 
has laid their Pipes and Canals in the Earth, like 
as he has planted the Veins, Arteries, and Glands, 
in an animal Body ; and that like wife they arc more 
and more ramify ’d, as they nearer approach the out- 
ward Shell of the Earth. 
The Workmen in Coal-Mines, and the like, ne- 
ver fail to meet with the Veins of Springs every- 
where : They that dig for Wells feldom fail of 
finding Water every-wherc. The Colliers are ob- 
liged to drain, at very great and continual Expence. 
A Circumfiance not very favourable to fubterranc- 
ous Fires. 
Now it is apparent enough, that the Hypothe- 
fls of Vapours, and fubterraneous Fermentations, 
Explofions, and Eruptions, being the Caufe of 
Earthquakes, mull abfolutely ruin the whole Syftern 
of Springs and Fountains, where-ever it has once 
been. But this is quite contrary to Fact j even 
where an Earthquake has been repeatedly ; for In- 
flance, from home. 
On IVedneJday , Jpril 6. iy8o. about 6 in the 
Evening, juft iuch another Earthquake was felt in 
London , and around it, as thefe two we have fecn. 
Another, exactly fimilar, in 1692. In all thefe 4 no 
Houfes thrown down, nor any Springs difturb’d there- 
by : No fenfible Eruptions or Smells. 
Thefe Confiderations I apply only to this little 
inconfiderable Space of a Circle of 30 Miles Dia- 
meter. But what is that to the Appearance of fome 
Earthquakes
