The Nature of SMixture. ~— Let L 

Ch. 3.$.8. » Onion, is when they touch in a Plain, As in the Cryftals and Shoot- 
ings of all Salts, and other like Bodies, For if we purfue their. di- 
vided and fubdivided parts, with our eye, as far as we cans they ftill 
terminate, on every fide, in Plains. Wherefore, ‘tis intelligible, That 
their very Atomes do alfo terminate, and therefore touch, in Plain, 
Concentration, is when two, or more Atomes touch by Reception 
Ch.3. §. 8. and Lutrufion of one into another: which is the clofeft, and firmeft

Ch.3: §.18. Natural and Artificial Mixture are the fame 3 
Miscture of all as in any fixed nnodorable, or untaftable Body: the 
Atomes of fach Bodies, being not able to make any Swell or Tafte, 
unlefs they were firlt difolved; that is to fay, unpin'd one from 
another. 
17. §. Hence, Sixthly, we underftand, how in fome cafes, there 
feemeth to be a Penetration of Bodies; and in what Jenfé it may be 
admitted: vz, if we will mean no more by Penetration, but Intrafi- 
on. Forthe Intrufion of one Atome into the Concave or hole of ano- 
ther, isa kind of Penetrations whereby they take up lefs room in 
the zzixed Body, then they would do by any other way of Contad. 
As anaked knife and itsfheath, take upalmoft double room,to what ° 
they do, when the knife is fheathed. Whence we may affign the 
reafon, Why many Liquors being mixeds take up lefs room or {pace, 
then they did apart; as the Ingenions Mr. Hook hath made it to appear 
by Experiment, that they do. [fay the plain reafon hereof, or at leaft 
one reafon, is the Ixtrufion of many of their Atomes into one ano- 
ther. Which yet isnot a Penetration of Bodies ftriGtly fo called. 
18. §. Seventhly, If all that Nature maketh, be but Mixture 3 and 
‘all this Mixture be but Conta *tis then evident, That Natural and 
* Artificial Mixture, are the fame. And all thofe feeming fubtilties 
whereby Philofopbers have gone about to d 
iftinguifh them; have 
been but fo many Svarcrows to affright ate from the Lwitation 
of Nature. 
19. §. Highthly, Hence it follows, That Art it (elf may go far in 
doing what Nature doth. And who can fay, how far? For we have 
nothing to Make; but only to mix thofe Materials, which are al- 
ready made to our hands, Even Nature her felf, as hath been faid, 
Maketh nothing xem 5 but only mixeth all things. So far, therefore, 
“as we can govern Mixture, we may do what Nature doth. 
20. §. Which that we may ftill the better underftand 5 let us be- 
fore, and in the next place, fee the Canfés of Mixture. For fince 
the immediate Canfes of 
both, are and muft be the fame. ¢
