dks there are Acid particles, that may juftly be called Fire.md 
that there is fuch a Fire in the Stomach of all Animais,and even ia 
the ventricles of all Mufcles ; (for,according tohim,every Muf- 
cle and part of the body hath its peculiar ventricle or ftomack, 
which impregnates the aliments convey 'd to them with the Semi- 
nal acid of the part, whereby the nourifliment is tum'd into the 
nature of this or that mufcle, or nerve, vein, artery, or any other 
part.) And as this Fire is by him placed in all Animals^fo he en- 
deavours to prove it tobe in all Minerals and Vegetables,where- 
by the matter, convey 'd to them for their nourifliment and in- 
creafe, is,according tothediverfityof the Seminal acid Sulphur, 
converted into this or that Mineral or Plant. 
Again, in that part of this Book, where the Author maketh it 
his bufinefs to prove, that the Tm Pr/V;^ of the Chymiftsare 
not the true Principles of Natural Things,he undertakes, where 
he treats of tjiat reputed Principle, Salt^ to bring clearer proof 
of what was formerly faid in Numb, 92. of thefe Tm^jnot to 
have been fufficiently prov'd, viz. That the fixed Alcalifate Salts 
do as fuch by no m.eans pre-exift in Bodies before Calcinations ; 
after he hath firft diftinguiOi't between the fixt Tartareous Salt 
that is in all the Juycesof Vegetables really and formally, with- 
out c-alcining them, fof which he faith he fpcaks not,j and the 
fixt AlcalifsLte Sd\.t oi the Tartar ^f.^.of Wormwood, which he po- 
fitively affirms nor have formally pre-exifted in the body be- 
fore calcination, becaufc he will have that produced by the col- 
liquation made by the fire of the Volatile Salts with the terre- 
ftnal parts of the body; and the Union of the Terreftrial parts 
with the Saline tobethe fole caufe of Fixity; a^on the other hand 
he maketh the feparation of thbfe Earthy parts the true and only 
reafon of Volariiicy. Which whether he hath evinced by fuch ir- 
refragable proots,as he thinks, we muft ftill leave to truly Phi- 
lor)phicaland fagacious Chymiftsto judge ^andfliall only take 
the 1 iber ty to demand, whether he be fure, That two Acids may 
jior without any Terreftreity be fo combined and brought into 
fuch a Texture, as to afford a Fixt Body, that fliall endure a con- 
iiderable degree of heat before itbefublimed or volatilized?
