Union, is when they touch in a Plain. As in the Cryftals and Shoot- 
ings Of all Salts, and other like Bodies. For if we purfüe their di- 
vided and fubdivided parts, with our eye, as far as we can 5 they (till 
terminate, on every fide, in Plains. Wherefore , ‘tis intelligible, That 
their very Atomes do alfo terminate, and therefore tonch, in Plain. 
Concentration, is when two, or more Atöwes touch by Reception 
and Ivtrafion of one into another: which is the clofeft, and firmeft 
Mixture of all; as in any fixed nmodorable, or untaftable Body: the 
Atomes of fuch Bodies, being not able to make any Smell or Taft, 
unlefs they were firft difoloed that is to (ay, umpir'd one from 
another. 
17. $. Hence, Sixthly, we underftand, how in fome cafes, there 
feemeth to be a Penetration of Bodies; and in what JSenfe it may be 
admitted: vz, if we will mean no more by: Penetration, but Intrufi- 
om. Forthe Intrufon of one Atome into the Concave or hole of ano- 
ther, isa kind of Penetration; whereby they take up leß room in 
the mixed Body, then they would do by any other way of Contatt. 
As anaked knife and its fheath, take upalmoft double room,to what 
they do, when the knife is theathed. Whence we may affign the 
reafon, Why many Liquors being mixed; take up lef room or fpace, 
then they did apart; as the Ingenious Mr. Hook hath made it to appear 
by Experiment, that they do. Ifay the plain reafon hereof, orat leaft 
one reafon, is the Intrufion of many of their Atomes into one anc- 
ther. Which yet is nota Penetration of Bodies ftri&ly fo called. 
18. $. Seventhly, If all that Nature maketh, be but Mixture 
all this Mixture be but Comtad ‘tis then evident, That Natural and 
Artificial Mixture, are the fame. And all thofe Jeeming fubtilties 
whereby Philofophers have gone about to diflinguifo them; have 
been but fo many Svarcrows to affright Men 
¿and 
from the Imitation 
of Nature. 
19. $. Eighthly, Hence it follows, That Artit felf may go far in 
doing what Nature doth. And who can fay, how far? For we have 
nothing to Make; but only to ix thofe Materials, which are al- 
ready made to our hands, Even Nature her felf, as hath been faid, 
Maketh nothing wem 5 but only »ixeth all things. So far, therefore, 
as we can govern Mixture, we may do what Nature doth. 
20. $. Which that we may (till the better underftand 5 let us be- 
fore, and in the next place, fee the Canfés of Mixture. For fince 
Natural and Artificial Mixture are the fame; the immediate Canfes of 
both, are and muft be the fame.
