is
the use of this same sulphur in a powder compound which, having been
ignited, throws out balls of stone, iron or copper from a new kind of
military machine. On the other hand the best use is in medicine. Since
it has the power of drawing out poison it cures the stings of sea
scorpions, marine reptiles and snakes. It can be spread on dry or mixed
with saliva, old oil, honey or turpentine according to Galen. Mixed
with soda it soothes the itch since it possesses the property of
cleansing. Mixed with vinegar it cures skin eruptions and when mixed
with turpentine it cures mange and rash. Bright yellow, transparent
sulphur that is not as hard as stone is selected for medicinal uses.
