in either of the Liquors. Whence it follows, that the very Mode of 
Mixture is fufficient, not only forthe 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,Tconceive, That as an Unduout 
Taft dependeth upon Oy! fo a Vapid either on Water, or Earth: or 
upon fuch an intimate Mixture of other Principles, as renders them in- 
difloluble by the saliva, and fo, in a manner, untaftable.

fharpned or whetted 5 that is, cleared from the foyl of other Princi- 
ples 5 asin the Spirit of Sal Aromoniac ox of Sulph And fo in thofe 
Plants which have a Pungent Tafts whole Juyces or Tindiures, although 
they confift of divers Principles, yet all fò 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 Jujce 
of fuch Plants, is a kind of Spirit of Nitre, made by the feveral Parts 
ofthe Plant. Hence Arum grows belt under an Hedg 5 where the 
Ground, not being expofed to the Suz, but the Aer only, like thofe 
Roows in Honfes,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-Veffelss whereby fewer parts of the mötroaerea] Sap are 
carryed off into the Trunk, For the fame Cau/é, it is no wonder, 
that many Aquaticks are Biting 5 Water b though it felf cold, yet 
the Menftrunm by which all salts are imbibed moft eafily, and in laxer 
Rate of Commixture with other Principles,

Salt that is alfo foiled or guarded with Barth. Somer, 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.

Sulphur. The particles whereof being Spherick and bored with holes 5 
thofe of Salt {tick in them, as the Spokes do in the Hub of a Wheel, or 
as the Quills in the Skin of a Porcupine. Whereby, as in Common Fire 
the Sparks of sulphur being agitated and whirled about by the 4er5 
with the help of the Salts, which ftick in them, tear in pieces all kinds 
of Bodies : fo here, being agitated by the Circulation of the Blood, they 
make a kind of hurry or combuftion 3 and fo, according to the degree 
and ftrength of their Motion, tear in pieces fewer or more of t i

Wherefore all Stillatitious Oyls are Hots being {trongly impregnated 
or armed with the Effeztial Salis of the Plants from whence they 
diftilled. And as thofe Plants which are very Parenchymous, from the 
predominancy of their Volatile Acid, are biting: So thofe which are 
Lignows, that is, havea good quantity of Ly» És, from the do- 
miou of their Sulph mmonly He For ıhe-fame reafon 
it is, that many both Biting and Hot Plants, as the Roots of Dragon, 
Garden-Radib, Onion, Tris, Rape-Cromfoot, &c. being corked up in a 
bottle with Water, and fet in a Cellar or other cool place; they do all
