fulphur precipitates, juft as in jhe common way of 
precipitating the decodtion of the fcoria of the regu- 
lus, or hepar antimonii. Though this fulphur au- 
ratum, as well as the other, like the alchemiftical 
gold, fo much talked of, and expedted, by the adepts, 
is much greater in profpedt than reality ; for when 
duly walked, feparated, and dried, it fcarce amounts 
to the fortieth part of what it feemed to be at the 
time of precipitation. I take this fulphur to be ra- 
ther milder, and more fixed, than that from the 
fcoria : however, here alfo is an abundance of regu- 
line parts, as is evident from the orange-colour, and 
the emetic quality, which this alfo poffeffes. This 
decodtion may as well be precipitated with juice of 
lemons or Seville oranges (which give the brighteft- 
coloured precipitate) j or by a folution of fal ammo- 
niac, or frefh urine : even common faliva will do it ; 
for, on taking a fpoonful of this perfedtly limpid 
decodtion into my mouth, it in an inftant turned 
intenfely yellow : fo that not only vegetable and mi- 
neral acids will precipitate this antimonial decodtion, 
but likewife neutral falf c . 
This decodtion of antimony in lime-water ferves 
alfo to a further end j for the mineral, thus boiled, 
may be in a great meafure deprived of its fuperficial 
fulphur, efpecially if boiled a fecond or third time 
in frefh ftrong lime-water. And then the powder, 
well wafhed and dried, is at fit for making regulus, 
or glafs of antimony, as when the ftibium is roafted 
and calcined in the common way. And perhaps 
antimony, thus prepared, may be more effedual in 
many cafes, than the crude, when given internally :
