soil which is affirmed to be impregnated with sulphur. 
4iot sulphureous waters gush out with such violence that 
the ground is agitated by very sensible shocks. It is said 
that llames have been frequently seen issuing out since the 
great earthquake of 1707. These facts are well worthy of 
being examined. '
