F ROM the aforefaid Premijfes, and by the aforefaid Means, thereds 
no doubt to be made, but that állo the other fèzfble Qualities of 
Bodies may be Imitated, as their Odors, and Tafts. And that not only 
the general ones, as Fragrant, or Aftringent : but alfothofe which are 
Specifical and proper to fuch a fpecies of Bodies. 
2. $. Thus for Example, by mixing Spirit of Nitre or Vitriol with 
reifified Oyl of Turpentine, and fome other Vegetable Oyls, feverally, 
and ina due Proportion and Time, I have Imitated the Smells of divers 
Vegetables 5 as of Tanfy, of Lignum Rhodium, and others, And I con- 
clude it feafable, To Imitate the Taft or Smell of Musk , or Amber- 
greece, or any otberbody in the world. 
3. §. Hence alfo we may be Taught, How to Imitate the Faculties, 
as well as other Qualities of Bodies. The reafon is, becaufe even thefe 
have no dependance upon any Jubifantial Form: but are the meer re- 
falt of Mixture; effected by the fame Cunfes, whether in Nature or 
‘Art; as [think I have made to appear in the foregoing Idea. And Id. $. 53.

of Bodies. For how far foever we can attain to Mingle, or to 
ke them, we may alfo know what they are. 
2. $. For Bodies are mingleable, either of themfelves, or by fome 
Third. As to thofe which mingle of themfélves, we may certainly con- 
clude, That there is a congruity betwixt them, in fome refpect or other. 
So upon various Tryals I find, That Effential Oyls do more eafily im- 
bibe an 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. 9. -Asto thofe that mingle only by fome third; we may alfo cer- 
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 Judgment 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 will do the like; 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 digefted the 
fame O)! in the fame manner, and for a much longer time, with ftrong 
Oyl of Sulphur; although it thenceacquired fome change of Colour, yet 
not any Confiftence. 
5. $. Again, Becaufe the faid Spirit of Nitre coagalates Oyl-Olive 3 
itmight be expected, it fhould have the fame effect upon Oy! of Ani- 
feeds; or, at leaft, that if other Acids will Coagulate Oyl of Anifeeds, 
that this fhould do it beft. But Experiment proveth the contrary. For 
of all I have tryed, Oy! of Vitriol is the only Acid that doth it inftan- 
taneoufly. Oyl of sulphur, if very ftrong, will doit; but not fo foo,
