springs of pure water which gush from rocks are
extremely cold ? A subterraneous fire must there-

probably at a very great depth beneath them,
yet sufficiently near to produce a very sensible
heat after passing a long dislance through cold
fubfiances.
The last., and as it appears to me conclu-
sive evidence, terrified the inhabitants of Bristol,
on the 1 st of November, 1755, when the wa-

esfect was produced by the dreadful earthquake
at Lisbon, and demonslrates a remote connec-
tion with the cause of that horrible convulsion
os Nature.
It would be futile to say the concussion of the
earth roosed a cleposit of soil from the sides and
bottom of the spring, and spread it through the
