2. Did Alcalies pr$-exift in Plants,prababJy Anima!s,whbre 
folc food they are, would alfo abound therewith ; whereas on 
the contrary we do not find the left footfteps thereof either in 
Blood, Urine, Bones, Horns, &c. which do all abouEid 
with r<?/4^/7 Salts $ nor in fome other parts, Excrements, and 
juyces, that afford ftore of Acidity, which may frequently 
by coagulation be brought to a Saline form or confiftence. 
Nor can it reafonably be pretended , that the Ferment of 
tKc Stomach and other parts, feveral Digeftions and repeated 
Circulations, have altered ifs property, and at length ren- 
dred it VolatiL For,^r/?, Alcalies feem to be of a very fixed 
nature, and arenoteafily volatilized : And daily experience 
will evince, that the Chyle doth not in the leaft participate, 
either in taft, or any other property, with Alcalifat Sales. 
Befides, Herbs taken out of tht OmAjm of ruminating Ani- 
mals, without any further digeftion or preparation yield a 
Volatil Salt whehfeimented or putrified in the open air, with- 
out additament. 
Moll: Vegetables, whether Woods or Herbs, if burnt 
whilft they are green, and with a fmothering fire , yield Salts 
which are far enough from Alcalifate ; being either Neutral 
or Acid, or, tofpeak more properly, Tartareous: For,, 
they do almoft exadly refemble purified Tartar; anddiftilled 
yeild the very fame fubftances. Indeed, fome few Herbs , 
fuch as Satureja, Rofemarj/y&cc. which abound with a fpright- 
ly volatil Oyl , if they are well dri^d, upon fimple incinera- 
tion yeild an Alcalifate Salt ; So do fome dry Woods. Bur, . 
that they are produced by the Fire, and not feparated , I ftali 
anon prove from Experiments, I think, unqueftionable and 
unanfwerable. 
4. In the moft naluralmethodof anal yfing Plants, which 
is by Fermentation or Putrefadion without additaments, or 
the intervening of a fufpicious Analyfer, we receive Oyl, A- 
cid Spirit, and Volati] Salt copioufly ; all which did evi- 
dently pras-exift. But, if the Herbs are perfectly or intire- 
ly putrified, little or no Jlcali can be extrafted from them 5 as
