in either of the Liquors. Whence it follows, that the very Mode of 
Mixture is fafficient, not only for the variation of the Degrees in any 
one Species of Taft 5 but alfo for the deftroying of one Species, and the 
introducing of another. ; 
6. §. THESE things being premifed,I conceive, That as an Unéinois 
Taft dependeth upon Oy!; fo a Vapid either on Water, or Earth: or 
upon fuch an intimate Mixture of other Principles, as renders them ins 
difloluble by the Saliva, and fo, ina manner, untaftable. 
7. § That a Pungent, is made either by an Alkaly or an Acid 
fharpned or whetted 5 that is, cleared from the foyl of other Princi- 
ples asin the Spirit of Sal Aromoniac or of Sulphur. And fo in thofe 
Plants which have a Pungent Taft; whole Fuyces or Lindures, although 
they confift of divers Priwciples, yet all fo loofely mixed, that being 
diffolved by the Saliva, the Saline are hereupon left naked. Where. 
fore biting Plants, qua biting, are Nitrous Plants, So that the Fuyce 
of fuch Plants, is a kind of Spirit of Nitre, made by the feveral Purts 
ofthe Plant. Hence Arum grows beft under an Hedg 3; where the 
Ground, not being expofed to the Su, but the Aer only, like thofe 
Roows in Houfes,which are covered, isimpregnated with a greater quan- 
tity of Nitrous salt. And thofe Roots which are Biting, have but few 
or but fmall Aer-Veffels; whereby fewer parts of the zitroaereal Sap are 
carryed off into the Trawk. For the fame Cane, it is no wonder, 
that many Aquaticks are Biting 5 Water being, though it felf cold, yet 
the Menftrunm by which all salts are imbibed moft eafily, and in laxer 
{tate of Commicxture with other Principles. 
8. ¢. Penetrant (fomething flower than Purgent ) is made by any 
Salt that is alfo foiled or guarded with Earth, Sower, by an Acid only 
foyled with Earth. Salt, by an Acid guarded.by an Alkaly, and foyled 
with Earth. Cold, by an Acid drowned in Water, and foyled with 
Earth, 
. §. Inall thefe, the salts are predominant; In Heat the Ojl o¢ 
Sulphur. The particles whereof being Spherick and bored with holes $ 
thofe of salt {tick in them, as the Spokes do in the Hub of a Wheel, or 
as the Quills in the Skiz of a Porcupine. Whereby, as in Common Fire 
the Sparks of Sulphur being agitated and whirled about by the Aers 
with the help of the salts, which ftick in them, tear in pieces all kinds 
of Bodies : {o here, being agitated by the Circulation of the Blood, they 
make a kind of hurry or combuftion 5 and fo, according to the degree 
and ftrength of their Motion, tear in pieces fewer or more of the Fz 
bers of the Tongue 5 and ina greater quantity, would raife a Blifter 
upon it; the common Effect of Fire, or any {trong Epi/pastickh. So that 
a Hot Taft, is produced by Swlphur toothed or armed with Suits. 
Wherefore all Stil/atitiovs Oyls are Hot; being {trongly impregnated 
or armed with the Efential Salts of the Plants from whence they are 
diftilled. And as thofe Plants which are very Parenchymous, from the 
predominancy of their Volatile Acid, are biting: Sothofe which are 
Lignows, that is, have a good quantity of Lymphedudts, fromthe do- 
miou of their Szlphur are commonly Hot. For the fame reafon 
it is, that many both Biting and Hot Plants, as the Roots of Dragox, 
Garden-Radifh, Onion, Iris, Rape-Crowfoot, &c. being corked up in'a 
bottle with Water, and fet in a Cellar or other cool place; they do all 
of them turn Sower in a few days: The fame Fermentation, at once
