Let. 1. The Power andUfe of Mixture. 335 


INSTANCE III, & IV. 
F ROM the aforefaid Premiffes, and by the aforefaid Means, there is 
no doubt to be made, but that alfo the other /exjible Qualities of 
Bodies may be Imitated, as their Odors, and Tafts. And that not only 
the geveral ones, as Fragrant, or Aftringent: but alfo thofé which aré 
JSpecifical and proper to fuch a fpecies of Bodies. 
2. §. Thus for Example, by mixing Spirit of Nitre or Vitriol with 
reEified Oyl of Turpentine, and fome other Vegetable Oyls, feverally; 
and ina due Proportion and Time, 1 have Imitated the Smells of divers 
Vegetables 5 as of Tanfy, of Lignum Rhodium, and others, And I con- 
clude it feafable, To Jwitate the Taft or Smell of Musk, or Amber- 
greece, or axy otherbody in the world. 
3. §. Hence alfo we may be Tanght, How to Imitaté the Farulties, 
as well as other Qualities of Bodies. ‘The reafon is, becaufe even the/é 
have no dependance upon any fbifantial Form: but are the meer re= 
fult of mixture; effetted by the fame Caufés, whether in Nature or 
Art; asIthink I have made to appear in the foregoing Idea. And Id, §. BS, 
as in the Premiffes of this Difcourfe hath been fhew'd. Ch.2.$.10.

ROM whence, again, it is likewife a Key to Difcover the Nature 
of Bodies. For how far foever we can attain to Mixgle, or td 
Make them, we may alfo know what they are. 
2. §. For Bodies are wingleable, either of themfélves, or by fome 
Third. As to thofé which mingle of themfélves, we may certainly con= 
clude, That there is a congruity betwixt them, in fomie refpeé or other: 
So upon various Tryals I find, That Effential Oyls do tore eafily im 
bibean Acid, then an Alkaly. Whence it is evident, That there is 
fome Congruity and Similitude betwixt Efentian Oyls, and an Acid, which 
there isnot betwixt the faid Oyls and an Alkaly. 
3. §. Astothofe that mingle only by fome thirds we may alfocer- 
tainly conclude, That though the two extreams are unlike; yet that 
they have both of them fome congruity with that third, by which they 
are united. 
4. §. Moreover, We may make a fudgment from the manner or 
Degree of Mixture. Thusthe Acid Spirit of Nitre, asis faid, will coa- 
gulate Oyl-Olive, and renderit confiftent. Whence it might be thought, 
That any other {trong Acid willdo the likes and that therefore, there 
is no great difference in the Nature of the faid Acid Liquors. But the 
contrary hereunto, is proved by Experiment. For having digeffed the 
fame Oyl in the fame manner, and for amuch longer time, with {trong 
Oy! of Sulphur; although it thenceacquired fome change of Colour; yet 
not any Confi/fence. ; eae 
5. $. Again, Becaufe the {aid Spirit of Nitre coagulates Oxl-Olive § 
itmight be expected, it fhould have the fame effet upon Oy! of Anis 
feeds or, at leaft, that if other Acids will Coagulate Oy! of Anifeeds, 
that this fhould do it beff. But Experiment proveth the contrary. For 
of all [have tryed, Oy! of Vitriol is the only Acid that doth it infbais 
taneonfly. Oyl of sulphur, if very ftrong, will do it; but not fo ie
