SECT. VIII.--_Observations on Sulphur, and its Combinations._

Sulphur is a combustible substance, having a very great tendency to
combination; it is naturally in a solid state in the ordinary
temperature, and requires a heat somewhat higher than boiling water to
make it liquify. Sulphur is formed by nature in a considerable degree of
purity in the neighbourhood of volcanos; we find it likewise, chiefly in
the state of sulphuric acid, combined with argill in aluminous schistus,
with lime in gypsum, &c. From these combinations it may be procured in
the state of sulphur, by carrying off its oxygen by means of charcoal in
a red h
