Whenceit follows, that the very in any Mixture is fafficient, not onlyfor the variation of the Degrees one Species of Taft 3 but alfo for the deftroying of one Species, and the introducing of another.

O fpeak of the Canes of Tafts, before we have well enumerated and diftinguifhed them ; is to provide Furniture for a Houfe,before the Roomes hive been counted and meafured out. Butthe of other Princéfharpned or whetted ; that is, cleared from the foyl X varieties of Tafts having been firft laid down ; 29) it will induce us to believe, and inveftigate as f. great a variety in their Cau/és. ‘ LY, 2. g. NowtheCanjes of Tafts, particularae SF Wyof the Tafts of Plants, whereof we chiefly {peak,are,in general,thefe Four or Five, fc. The Bed out of which they grow; The Aer in whichtheyftand; The Parts of which theyconfit; The feveral Fermentations under which their Fuyces pafs ; And the Qe fans by which their Taftable Parts are perceiv'd: as will appear upon nftance. 3. §. But the immediate Caufes, befides the Organs of Taffe, are the Principles of Plants. As many of which, as come under the noes of Senfe, we have already fuppofed to be thefe Seven, Alkaline, Acid, Aer, Water, Oyl, spirit and Earth. The Particles both of Alkaline age Acid Salts, are all angular and poynted. Thofe of Aer, properly and ftritlyfo called,are Elaftick or Springy; and therefore alfo Crooked 3 as I have likewife formerly conjeGtured. And find the Learned Borel in a Bookofhisfince then publifhed,to be of the fame Opinion. Thofe ot all Fad Bodies, qua Flvid, and therefore of Water, Oy] and Spirit I conceive to be Globular, but hollow, and with holes in their Sides, Thofe of Water, to be larger Globes, with more holes; thofe of Oyl, to be leffer, with fewer holes 5 and thofe of Spzrit the leaft. Laftly. that ih pace of Earth are alfo Round; yet angular 5 and nearer bon old. 4. §. Thefe Principles affe& the Organs of Senfe, according to the variety of their Figures, and oftheir Mixture. So thofe which are {harp or poynted; and thofe which are fPringy 3 are fitted to produce any ftronger Tafte : and thofe which are round, are apt, of their own Nature, to produce a weaker or fofter one. And fo by the diverfities of their Mixture; not only with refpett to their Proportion, but alfo the very Mode of their Conjunéfion. Hence it is, that many Bodies which abound with Salt, as Ambar withan Acid. and the Bones of Land-Animals with an Alkaline, have notwithftanding but a weak Taft, the Saline Parts being in the former drowned in the Oyl, andin the latter alfo buried in the Earth. 5. §. i Thefame is further confirmed by an Experiment mentioned _ ina former Difcourfe 5 fe. the Tranfimtation of Oyl of Anife-Seeds, with the help of Oy! of Vitriol, into a Rofiz. For both thofe Liquors, though fo {tronglytafted, apart; yet the Rofiz made of them, being well wafhed, hath a very mild Tafée, and without any fmatch ofthat in TTA bh Hil} Mini of Tafts, Lea.

And fo h ‘Plants which have a Pungent Taft, whofe Fuyces or Tinitures, althoug that being they confift of divers Prénciples, yet all fo loofely mixed, Where. diffolved by the Saliva, the Saline are hereupon left naked. the Fuyce fore biting Plants, qua biting, are Nitrous Plants. So that Parts of fach Plavts, is a kind of Spirit ofNitre, made by the feveral the ofthe Plant. Hence Arum grows beft under an Hedg; wherethofe e Ground, not being expofed to the Sun, but the Aer only,lik quanRoows in Houjés,which are covered, isimpregnated with a greater tity of Nitrows Salt. And thofe Roots which are Biting, have but few al Sap are or butfall Aer-Veféels; whereby fewer parts ofthe nitroacre wonder; no carryed off into the Truk, For the fame Cane, it is cold, yet that many Aquaticks are Biting 5 Water being, thoughit felf in laxer the Menftruum by which all salts are imbibed moft eafily, and s.
