conimixture of the Fixt Salt was quite inojdorpuSj yet now af-

that even when put from the fire 5 infomuch that if you do not, 
after the toixiog of the Fixt Salt, very accurately clofe yoUr 
veflcl, you i^ill afterwards find no Spirits at all Whereforfe 
as in this Example of Sal Armoniac\ the Fixt fait added^ 
freeth the Alealifat portion of the Salts 5 fo in this 
Fermentation of Tartary the Tartar calcined to blackneis, 
or the Fixt fak of Tartar^ freeth the Alealifat part of the crude 
Tartar from the Acid parts^ For, faith he, in the crude Tartar 
or its putrified Grcme there are^ as in Sal 4rmom4c^ two Vo- 
latil Salts, an Alcali and Acid, from the colliquation of which 
(as hath been faid^ theFixt faltrefults; fincc *tis nof orious,that 
in the fermentation of wine the particles do coagulat the 
fuperabounding Alealifat with the Terreftrial ones to the very 
degree of laturation , and fo by their increafed weight take 
place in the lower part of the veflcls^, 
If therefore to this Tartar^ pregnant with Salts, crude, or 
depurated by a fblution IP water, you add a calcined Tartar^ 
or, which is the fame, Salt of Tartar it felf, ijcnmediatcly this 
Fixed fait will lay hold on the Acid portion of the crude Tar- 
tar, andj as in thQ Sal Armniac^ fo here, freethe volatil Al- 
ealifat J from which coofiift and aftion of the fak onone anb-

_ cin'd Tartar muO: be cootiouedy until! all Fermentation do 
ceafb, that to the very degree 6f Saturation : which unlefi 
it be well obfervedj many inconveniences will obftruftthe 
Operator. But this volatil Ala^li^ being by means of the cal- 
cined Tartar freed from its Acidj (like the Urinous of the Sal 
Armmai^^ will prefently fly away. Wherefore if this volatil 
Spirit could forthwith be received, it would afford a real vo- 
latil Salt of Tartafj, cfpecially ifby art it were freed from its 
phlegme (which makes it a fluid Spiri^,). and, without the ad- 
dition of any extraneous thing, coagulated into Salt. ?ut 
this cannot be, faith feeing that^beforc all the fermentatiofl 
and mption of the faline particles (hall have ceafed, this 
mixture cannot ber put into the Gucurbitj becaufe it would
