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

with warer.

Spiril of nitre, well dephlegmated, and combined wirh

fpirit af wine, preCents likewife fome very fingular ap–

pearances.

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.
