is come over ; after which let the Fire go out ; take 
oft the Receiver, and carefully pour the Liquor into 
a Glafs Phial, to be flopped with a Glafs Stopper. 
The volatile Spirit, thus procured, will be about 
Twelve Ounces in Weight, and appear tolerably 
limpid, fmell extremely quick, pungent, and Gaffy or 
fulphureous, almofl like the Gas Sulphur is , prove 
ftrongly acid to the Tafte, and in all other Experi- 
ments ; fo that it may be ufed in the way of a general 
Acid ; being, perhaps, the beft, in all refpedts, that 
is hitherto known, except the following : 
Process IL 
To make the volatile Spirit of Sulphur cum Cake. 
Take a Pound of the Flowers of Brimftone, Four 
Pounds and an half of fixed Alkali Salt ; grind and 
mix them well together ; put the Powder into an 
Iron Pot fet over the Fire ; add a little Water, by de- 
grees, to diffolve the Salt; then boil gently for a 
Quarter of an Hour; add more Water, and after- 
wards Three Pounds of ftrong Quick-lime ; let ail 
boil together for a while: When the Solution is 
complete, filtre the Lixivium, and evaporate to a 
dry Powder, as in the Firft Procefs ; put this Powder 
into a tubulated Retort ; and pour on, by degrees, a 
Pound and an half of re&ified Oil of Vitriol ; pro- 
ceed to diftil as before: Thus ye will obtain Eight 
Ounces of a more ftrong, more acid, and more 
volatile Spirit, than the former, and of a yellowifii 
Colour.
