The reaCon of all Ihe phenomena above·mentioned,
refulring from Ihe mixture of fpiril of \Vine wilh oil of
vitriol, is founded on the g.real affiniry between this acid
aod warer. For if Ihe vitriolic acid be weak, and as it
were over-dofcd \Vith walcry pam, neilher oil nor 3!lher
Cdnbe oblained by means lhereof: Bur when highly cod–
centraled, it attrdéls the aqueolls pans ''fry powerfully'¡
and therefore being mixed with fpiril of wioe, lays hold
of mofl of the waler contaioed in ir, aod even robs il of
Come ponion of thal which is elfeolial tOirs nalure,' and
neeeITary ro conltitule it Cpirit of wioe: Whence'ir comes
10 pafs, thar a cenain quaOlily of the oily panicles in its
compofition being Ceparaled from the watery particJes,
and fo broughl nearer 10 each other, they unite and af–
fllme lheir nalural farOl ¡ and thus !lle oil that fIVims
al
10p of Ihe Culphureous phlegm is produced.
The vitrialic aeid moreover lhickens and eveo bures
fome of Ihis oil; and hente comes the bituminous refidn–
um left al the bOtlom of lhe flill,
whi~h
looks like the
refull of a ,itriolic acid combined \Vilh common oil.
LaOly, the vilriolic aeid becomes Culphureous, as it
al–
ways dOlh whcn lIniled with oily maners, and alfo very
aqueous, on accounl of Ihe quantilY of phlegmwhich il
attraéls from the fpiril of wine.
JElher may be confidered as a fpiril of \Vine exceed–
ingly dephlegmmd, even
10

Spiril of nitre, well dephlegmated, and combined wirh
fpirit af wine, preCents likewife fome very fingular ap–

Firll, in the "ery innant of its mixture with fpirit of
\Vine, it produces a grealer and more violeol efl'erveC–
ceoce than lhe vitriolic acid oceafions.
