P bilofophical History of Plants. | ai 
55- §. And ifby means of the faid Organical Parts, it is, that their 
Contents become fuch and fich peculiar Mixtures ; it is hence alfo mani- 
fe(t, That, by the fame means, they are of fuch diftin& Faculties and 
Powers: Becaufe the Faculty or Power of a Body, lieth not in any of 
its Principles apart 5 but isa Refultance from them alls or from their 
being, in fuch peculiar fort and manner, United and Combined toge- 
ther. So the Principles of the Purgative Parts ofa Root, as of Rhu= 
barb, although we fhould fuppofe them tobe exiftent in the furround- 
ing Earth, yet we cannot fay, That that Earth, or the Principles there- 
in contained, are Purgative; but only that theyare fuch, as by being 
combined together, in fuch a peculiar way, may become fo. So the fe- 
veral parts of aClock, although they are and mutt be all pre-exiftent 
to it, and it is their Form, by which they are, what they ares yet is it 
the fetting together of {uch Parts, andin fuch a way only, that makes 
them aClock, And fince we fee that the Mixture of two Bodies of two 
different Qualities, as of Two Colours, will produce a Third Colour, 
differing from them both 5 as Blue and Red, do a Murrey : Why fhould 
not Two or More Bodies of different Natures, be fo combined to- 
gether, as to produce a Third Nature? Or whereforemay not that be 
allowed to be performed by Nature, which by Artificial Compounding 
of Medicines, or other Bodies, is defigned, and oftentimes effected ? I'll 
give but one Inftance ; Water, Greafe, and an Alcalizate Salt, may be 
eafily {0 ordered as to be invefted with new Qualities, Nature, and 
Powers 5 the Salt, to lofe its extreme fiery Pungent Tafte 5 the TaVow,its 
Swell; and being before unfociable with the Water, to mingle there 
with: neither Tallow, Salt, nor Water alone, will fetch out a fpot of 
Greafes but all united eafily doit: the fame Three Bodys united, are, 
in fome Cafes, as in the Fanmdies, no ill Medicine , any of which, gi- 
ven alone, may rather prove prejudicial, than a cure: and all this done, 
only by duly boiling them together into one Body, which we call 
Sope. 
56. §. Whence again, if it be fuch an Uziow, and Proportion, of 
fuch a Sort of Principles, which produceth fuch a Faculty and that 
we may, by any means, come to know what thefe are 5 we may, pofli- 
bly, alfo attain to the knowledge of fuch Rules, whereby any kind of 
Faculty may be made; as to Compound fuch Bodies, which are neither 
Purgative nor Vomitory, fo together, as to beInvefted with thofe Fa- 
culties. And ifto Make them, then confequently, to Mend, Exalt, 
Strengthen, and Enoble them, with greater eafe and certainty. And thus 
much for the Fourth General Meaz, 
57- §. HITHERTO, We haveconfidered the Materials ofa Ve- The Fiftti 
getable, only asIngredient to it : there yet remains a Fifth story to be General 
afcended; which is, to confider thefe Materials as they are derived Mean. 
from abroad : oras, after they are received and naturalized, they may, 
with others yet abroad, have any kind of correfpondence. And thefe 
are Four in general, (cil. Earth, Water, Aer, and Suz all which, in 
that they contribute fo univerfally to Vegetation, and to whatfoever is 
contained in a Vegetable, it is therefore requifite, that of Thele likewife, 
Particular Obfervation fhould be made. ; 
58. §. And Firft, of the Barth, and of all Solid Receptacles of 
Plants. Where we are to confider their feveral Kinds; as Mellow; 
Sandy, Clayie, Chalky, and others, Their Ingredients; as Rank and
